The characteristics of organized sport and physical activity initiatives for older adults in Sweden

There is a common understanding that sport and physical activity can be important to address healthy aging. There are individual-level recommendations about how much physical activity people of different ages should engage in to gain health benefits, but at the same time there are no recommendations for how organizations should organize physical activities to suit as many people as possible for as long as possible. The purpose of this study was to explore the characteristics of sport and physical activity initiatives that older adults participate in. Different ongoing sport and physical activity initiatives that involve older adults were investigated regarding their focus, organization, intensity and organizer, and in relation to their costs, booking opportunities and recruitment. The study was conducted with a cross-sectional design using the Salutogenic Physical Activity Health Resources Questionnaire (SPAHRQ). The study included 27 different initiatives with 372 participants (60% women) ranging from 60 to 96 years of age. A health-promoting, salutogenic settings-based approach, and specifically the concepts drop-in, drop-through and drop-over were used in discussing recommendations for the organization of sport and physical activity for older adults. The main findings were that who organizes the sport and physical activity initiative seems to affect the characteristics of how it is organized and what characterizes the participants in it. Despite the differing characters of sport and physical activity initiatives, the majority of older adults are recruited by internal contacts like friends and family. Which older adults participate in which initiatives is explained mostly by the age and gender of the participants. In conclusion, to attract as many older adults as possible, organizations should work with lowering the thresholds, as well as within and between, organizations, and raise the threshold for dropping out of sports and physical activity.


Introduction
There is a widespread belief that sport and physical activity is an important "player" with regards to addressing healthy aging.There are individual-level recommendations about how much physical activity people of different ages should engage in to gain health benefits (1), but at the same time there are no recommendations for how organizations should organize physical activities to suit as many people as possible for as long as possible.The purpose of this study is thus to explore the characteristics of sport and physical activity initiatives that older adults participate in and to discuss this in relation to recommendations for how arrangers could organize activities for older adults.

Participation in physical activity and sport for older adults
Participation in organized sport and physical activity provides substantial physical, psychological and social health benefits for older adults (2)(3)(4).Regardless of these apparent benefits, older adults represent one of the least physically active groups in society across the globe (5,6).
At the same time, few older adults participate in sport clubs (7,8).Most older adults instead engage in physical activity in their own regime, the most common activity being walking (9).Older adults also have different purposes, presumptions, and background regarding sport and physical activities in organized form (10,11) and having a history of engaging in sport and physical activity throughout life can lead to being generally more active in older age (12).It can thus be concluded that older adults are a heterogeneous group with regard to sport and physical activity (10,13), although what they find meaningful in the activities can be quite similar (14).

Organization of sport and physical activity for older adults
Older adults have mainly been explored regarding individual perspectives on engaging in physical activity, for example motivation, confidence and resilience (15,16) as well as barriers to participating (10,17,18) and reasons for dropping-out of organized sport (19).
There are limited studies, however, about the organizational perspective on older adults and sport (20), and more attention could be paid to these dimensions of the "how" in organizational contexts and contents (4).The studies that have focused on the organizational dimensions of sport for older adults emphasize aspects such as adaptations to create age-appropriate opportunities (19), modifications in rules (21), or even creating new forms of sport, similar to walking soccer (22).Some studies conclude that older adults often are recruited to sport by internal contacts, like personal invitations (21, 23), and that external recruiting is important but needs more explicit strategies, for example highlighting the different experiences and health and social benefits that participation can give (21).Previous studies are highlighting that senior associations are emphasized as an important place of recruiting and communicating with old adults about PA (21,23,24).Participation fees are mentioned as a structural feature that can affect organizing perspectives; for example, passing over used equipment between participants could be a solution for older adults with different economic possibilities (21).So, with this in mind, lowering the thresholds, for example meaning it should be easy to start exercise without no earlier knowledge or experience and where recruiting also is especially important for increasing diversity and reducing social inequality (24).

The sport and physical activity landscape for older adults in Sweden
There is not much research on what physical activities older adults participate in globally, and this is also the case for Sweden.One smaller Swedish survey revealed that less than one third of the older adults in Sweden were members of a sports club, and slightly more men than women (9).In a national survey on older adults participating in sports clubs it was concluded that this group was homogenous related to socioeconomic status (with a relatively high socio-economic status), but heterogeneous in relation to which sport and physical activity they engage in (25).
In a study from Huffman and Amireault (13) they argue that the organizing of activities for older adults needs to consider a multilevel perspective, such as a socio-ecological framework.This is a conclusion that studies on youth sports have also reached (26,27).However, there has been a limited focus on the organizational perspective in research on older adults' sports participation.Studying sport and physical activity initiatives that are ongoing and exploring how they are designed can thus be a way to understand older adults' participation in sport and physical activity in later life.If they are organized traditionally and similarly for all age groups and genders, there is a danger of missing out on possible participants and perhaps creating overly narrow or conservative activities which could lead to limitations in encouraging participation (13).This research therefore aims to identify what characterizes (in this particular study: costs, recruitment, booking system, type of activity) sport and organized physical activity initiatives for older adults.

The present study
The purpose of this study is to explore the characteristics of sport and physical activity initiatives in Sweden that older adults participate in.In the study, we will investigate different ongoing sport and physical activity initiatives that involve older adults with regard to their focus, organization, intensity, and organizer (see Table 1) (28).We will answer the following research questions: 1) What characterizes the sport and organized PA initiatives that older adults participate in? 2) What characterizes older adults who participate in different sport and organized PA initiatives?
We will investigate this using four proposed activity categories, focus, organization, intensity, and organizer, analysing these in relation to both organizational variables and participant variables to answer the two research questions.In this way, questions like these can give a more complete understanding of the characteristics of organized sport and physical activities for older adults.
In this study, we have used a salutogenic settings-based approach to health promotion in line with (26) to discuss our results in relation to recommendations for how organizers could organize activities for older adults.
The salutogenic settings-based approach has its origin in both salutogenic theory Antonovsky (29,30) applied to a sport context (31) and a health-promoting, settings-based approach for sport clubs Geidne et al. (32), and Van Hoye et al. (33).The salutogenic perspective in health promotion stems from a critique of a dichotomous classification of people as healthy or diseased, and a focus on disease "as the departure from the norm and the normal, as that which has to be explained" (30).In this study we will specifically use the concepts employed in (26), i.e., drop-in, drop-through and drop-over, in discussing recommendations for the organization of sport and physical activity for older adults.These concepts are also discussed in relation to each other using the word thresholds which can be thought of as steps/changes/phases more than clear cut-points, to discuss how to lower the thresholds into the activities, within the organizations and between the organizations to increase the threshold of drop-out of PA and sport initiatives.

Study design and context
This study was conducted with a cross-sectional design using a questionnaire to collect data from 27 ongoing organized sport and physical activity initiatives with older adults in Sweden.The 27 initiatives were either organised by a senior association or a sports club (none in private regime).Ethical approval was granted by the Swedish Ethical Review Authority (Dnr 2019-04818).The Swedish sport movement is traditionally organized as non-governmental organisations but has extensive government funding that could be described as an "implicit contract" (34).In recent decades there has also been an increase in other types of actors, like companies and other organizations that run sport activities in Sweden (35), a trend that can also be observed in other western countries (36).

Participants and procedure
The sport and physical activity initiatives were located among both senior associations and sport clubs with ongoing regular sport and physical activities in and around a medium-sized city.The sampling was conducted with a snowballing strategy (37) (using network contacts in the county sports federation, organizations, and others) to find as many of the ongoing sport and physical activity initiatives in the region as possible.The criteria for inclusion were that sport and physical activity initiatives should be organized and offer weekly group activities for participants 60 years and above.Exclusion criteria were not organizing for a group or being explicitly organized as rehabilitation, prevention, or treatment of disease, for example an activity prescribed or recommended by the health care system.
The recruitment process consisted of contacting the head of the organization/sport club manager by phone.The participants in the 27 recruited initiatives were initially given oral information by the group leader at one of their regular sessions, one week before the data collection took place.Written and oral information were then provided to the participants and informed written consent was received.The questionnaires were handed out in person (in paper and pen form) by the first author.Reading glasses were available, in case participants did not bring them to the training sessions.The participants could fill out the survey on site or request a postage-paid, addressed envelope to send it from home.It was possible to ask questions while filling out the questionnaire on site and also to get in contact with the first author by e-mail or phone.All participants were active in these ongoing organized sport and physical activity initiatives on a voluntary basis.The study took place from December 2019 to early March 2020, when the data collection had to cease due to the Covid-19 outbreak in early spring 2020.All questionnaires were coded and handled confidentially.

Measures
The questionnaire that was used is the Salutogenic Physical Activity Health Resources Questionnaire (SPAHRQ), developed from previous studies on physically active older adults (14,38).SPAHRQ was developed using a salutogenic theory-driven approach as introduced by Antonovsky (30, 39) and further developed for use in studies within sport and physical education (31,40).The SPAHRQ questionnaire has been used to report other outcomes in the same sample but in this particular study variables focusing sport and PA participation are presented.The questionnaire has been used in an earlier study (14).Briefly, salutogenic theory assumes that how we understand health is

Activity organizer
Activity organizer refers to the organizing club or association.A senior association is one where activities take place only for older adults (60+).Sport clubs can have both senior-specific initiatives and activities for other age groups and different purposes; the participants included in this study are in senior activities only.

Activity focus
Activity focus, with the possibility to compete or participate exclusively as a leisure activity.Here activities are categorized as either/or; i.e. if there is a possibility to compete (ex.golf, tennis) even it is categorized as competition, even if someone chooses not to do so.

Activity organization
Activity organization concerns activities requiring a team (or at least an opponent to play against) to take part in, as opposed to individually performed activities (though still in a group).

Activity intensity
Activity intensity describes the level of intensity of the activity and was labelled as low intensity (MET < 4) or medium-to-high intensity (MET > 5) according to the MET table scale (28).
Ericson and Geidne 10.3389/fspor.2023.1168312 Frontiers in Sports and Active Living 03 frontiersin.orgclosely related to both our social, cultural, and natural environment, and our physical, social, and mental resources as individuals (31,41).
A salutogenic perspective consequently helps us consider individual and organizational aspects of older adults' participation in organized sport and physical activity initiatives as well as the relation between individual and organizational aspects.The focus of this study is on organizational-level characteristics of the physical activity initiative in which the older adults participate.As a tool for analysis, the initiatives were first categorized by the authors into four dichotomous pairs inspired by Eime and colleagues' (42) categorization of leisure-time PA by type (which sport or exercise), mode (team-sport, individual sport, exercise and non-organized PA) and setting (school, sport club, home, public park, etc.).Since these terms are based on adolescents' leisure-time PA, we have adapted and refined them into the four category pairs: activity organizer (senior association or sport club), focus (competition or leisure), organization (individual or team) and intensity (low or medium to high).
Here follows information about the categorisation.Activity organizer refers to the organizing club or association.A senior association is one where activities take place only for older adults (60+).Sport clubs can have both senior-specific initiatives and activities for other age groups and different purposes; the participants included in this study are in senior activities only.The activity focus, with the possibility to compete or participate exclusively as a leisure activity.Here activities are categorized as either/or; i.e., if there is a possibility to compete (ex.golf, tennis) even it is categorized as competition, even if someone chooses not to do so.Activity organization concerns activities requiring a team (or at least an opponent to play against) to take part in, as opposed to individually performed activities (though still in a group).Activity intensity describes the level of intensity of the activity and was labelled as low intensity (MET < 4) or mediumto-high intensity (MET > 5) according to the MET table scale (28).
The 27 initiatives in our final sample were relatively evenly distributed according to number of participants between the activity pairs in the categories activity organizer and activity intensity, but differ in activity focus and activity organization.(Activity focus had more leisure than competition initiatives, and activity organization had more individual than team initiatives; see Table 2).Sports and physical activities represented in the 27 initiatives are; group gymnastics, water exercise, which covered almost half of the participants.The other initiatives included are resistance training, tennis, table tennis, indoor boule, walking football, senior Tabata, dancing, golf, bowling, wrestling and outdoor walking.The sports and activities are not seasonally dependent, but ongoing all year round.
The activity categories were then related to the organizational characteristics of sport and physical activity initiatives regarding costs (average in Euros), booking possibilities (three categories), and recruitment to the initiative (three categories).These variables were chosen because they were the quantitative variables on organizational level in SPAHRQ that answered to the first research question.The activity categories were then related to the participants' demographic factors age, gender, education level, city size, and time spent in physical activity per week (overall) to answer to the second research question.Education was assessed and classified according to the International Standard Classification of Education from UNESCO (43) with (1) low-level education (at most nine years of school), ( 2) medium-level education (secondary school) and (3) high-level education (high school and university studies).

Statistical analysis
Descriptive statistics, chi-square tests, t-tests and multivariate logistic regression analysis were performed to determine differences between independent variables related to the four activity pairs.Covariates in the multivariate logistic regression were participants' age (continuous), gender (men, women), education (categorical), and city size (categorical).The percentage of missing data for the logistic regressions was 8%, and this was left out of the analysis in listwise deletion (removing all data for a case that has one or more missing values) (44).The data analysis was performed using IBM SPSS version 26.

Results
The study included 27 sport and physical activity initiatives with a total of 372 participants, ranging from 60 to 96 years of age (mean age: 74.4 ± 7 years); 60% were women.Almost all the initiatives had participants with a high level of physical activity in everyday life; 93% met the general criteria of 150 min/week of physical activity from self-rated data obtained in the SPAHRQ questionnaire (mean 634 ± 464 min/week) and a range of 90.Below, the results on the first research question on, characteristics of the sport and PA initiatives are presented.Followed by the results for the second research question, what characterizes the participants in the different initiatives.

What characterizes the different initiatives?
Costs for the initiatives vary from free (zero) up to around €2,000 for a one-year membership and participation, M (SD) = €149 (117).The lowest costs are found in senior associations,  3).In senior associations, the cost per year is on average €46, compared to an average of €217 in sport clubs.The most expensive activities were tennis and golf.There are also differences in how the participants book their activities in the different initiatives.In senior associations, most activities were booked per semester 60%.In sport clubs the most common booking system was per occasion, 40%.In team sports (almost always in sport clubs), the most common way of booking was per semester (46%).The recruitment into the initiatives on the other hand was very similar between the different activity categories.Around 70% were recruited by an internal contacts like family, friends, and colleagues, around 25% by an external contacts like advertisements or senior exhibitions, and around 5% at the participant's own initiative.
What characterizes the participants in the different initiatives?
The initiatives with the most participants were found in group gymnastics and water exercise, which covered almost half of the participants.Sport clubs have significantly more younger participants (age group 60 to79 years) than senior associations (89% vs. 72%, p < 0.001) (Table 4).Senior associations further had significantly more female than male participants (71% vs. 50%, p < 0.001).Sport clubs had significantly more participants living in cities (74% vs. 30%, p < 0.001) than senior associations.Due to the activity focus, significantly more men participated in competitive activities than women (78% vs. 11%, p < 0.001).The same result was found for team sports when comparing men and women (60% vs. 10%, p < 0.001).Initiatives with medium-to-high intensity level of the PA had more participants in the 60 to 79 age-range than low intensity PA (89% vs. 71%, p < 0.001).A majority of initiatives had participants who began with the activity 1-4 years ago.
A multivariate logistic regression was performed to control for all the variables in one block (Table 5).Age and gender were the variables that had the most effect on which initiatives the participants were involved in.The greatest difference and main finding is that men participate in team sports to a greater extent than women (OR = 21.6).Concerning the focus on the activity, younger participants and men participate in competitive sports to a greater extent than women in this study.In activities with medium-to-high intensity, compared to low, the age is higher.The results also reveal that which organization that organizes the activity is significant for who the participants are.In sport clubs, compared to senior associations, we find male and higher-educated participants to a greater extent, and people living in small towns to a lesser extent.
These findings indicate that the characteristics of both the participants and the initiatives in which they participate are varied.

Discussion
This study has identified characteristics of sport and physical activity initiatives that older adults in Sweden participate in, in terms of how the initiatives are organized and what characterizes the participants in the different initiatives.Exploring sport and physical activity initiatives that are ongoing and investigating how they are designed are a way to better understand older adults' participation in sports and PA and thus be able to organize activities that are more beneficial for their participants.It is of great importance for society as a whole that older adults are physically active and that there are relevant activities for them to participate in.
Our main findings predominantly concern the differences between different organizers, in this study divided in sport clubs and senior associations.Who organizes the sport and physical activity initiative seems to affect the characteristics of how it is organized and what characterizes the participants in them.Secondly, despite the different characters of sport and physical activity initiatives, the majority of the older adults are recruited by internal contacts like friends and family.Thirdly, which older adults that participate in which sport and physical activity initiatives can be explained mainly by the age and gender of the participants.Below we will discuss our main findings in relation to previous research and then present our findings in relation to recommendations for possibilities for how older adults can "drop-in", "drop-through" and "drop-over" in sport and physical activity initiatives as a way to reduce drop-out, in line with the suggestions from Geidne and Quennerstedt (26) and Geidne et al. (25).

Results discussion
To our knowledge, research comparing different types of sport and PA initiatives for older adults in relation to costs, booking and recruitment is lacking.Consistent with previous studies (45,46) we show that the sports club and the senior associations creates a valuable setting to promote health, with our research adding fresh insights to the small but growing corpus of evidence specifically on health-promoting initiatives for older adults.
Which actors that run sport and organized physical activity for older adults can differ between countries, but also within countries (47).In Sweden, most sports are organized by sport clubs that are non-governmental and are included under the umbrella organization the Swedish Sports Confederation.Organized PA can be organized by sport clubs, but also by other organizations, both non-governmental and private.In this study, one of our main findings was the significant differences in both the character of organizations and the participants in them, regarding whether it was a sport club or a senior association that organized the activity.Sport clubs were generally more expensive, even if some sport clubs have senior discounts and cheaper booking in daytime.However, if equipment is necessary for an activity, costs can still be high.One explanation may be that senior associations have less expenditures for renting spaces for activities, since several of the initiatives take place in rooms also used for meetings and by other organizations.Senior associations also had more booking per semester than per occasion, as is more common in sport clubs.There was a large difference, however, between different sports, with golf, for example, more often being booked per occasion, but not table tennis.
Another important finding of our study is that, regardless of what characterizes the activity and the different participants, a vast majority of the participants are recruited by family, friends, colleagues or other internal contacts.Similar results are found by (21, 23), who conclude that most older adults are recruited by internal contacts and personal invitations.External recruiting is important, but needs better and more explicit strategies, according to West et al. (48).If the majority of recruiting is internal it is a risk that many older adults will not participate to this kind of sport and PA initiatives also in the future.This can also be discussed in relation to the group of participants included in our study, because they are a very homogeneous group in terms of socio-economic status and health (14).If most participants are recruited through family and friends, there is a risk that some groups never get invited to join or even know that such activities exist, which will affect the diversity of participation and also lead to social inequality (24).The third main finding that stood out concerned the differences related to age and gender.Men were more than 21 times more likely than women to be participants in team sports.One explanation of this could be that women who were young in the 1960-70s often did not have the same opportunities to participate in team sports, and what you do early in life often affects what you do later (12).On the other hand, women participated more often in individual activities.The gender differences in team sport at an older age are in some studies explained by women reported having more barriers to exercise than men (49).Another study also strengthens the argumentation that males were more motivated than females by mastery and competition in sports, whereas females were motivated more than males by appearance and physical condition (50).The results also show that the intensity of the activity decreased with increasing age.This could also be related to the fact that older women more often participate in senior associations, where individual low-intensity activities are more common.In senior associations, the cost of the activities was also lower and, as Wong et al. ( 51) also state, the financial insecurity that some groups experience in later life, for example women, can impact their ability to afford and access physical activities.Due to the results that men often participated in competitive sports than women are in line with what both Hirvensalo and Lintunen (52) and Chen et al. (53) found.Playing competitive sport at younger age was a significant predictor of sport involvement during old adulthood (53).

Recommendations for drop-in, drop-through and drop over in relation to older adults
In response to the lack of explicit recommendations for how organizers could organize activities to suit as many people as possible for as long as possible, in this section we will offer some suggestions regarding how older adults can drop-in, dropthrough and drop-over in sport and physical activity initiatives as a way to reduce drop-out.
Drop-in concerns recommendations for how to lower the threshold for older adults to start to be active, from the beginning, after a break, or when switching to a new activity.For older adults who used to participate in sports (or have done so continuously since they were younger) the threshold to continuing when older or starting a new activity is probably lower than for someone who has never participated in sports.On the other hand, the threshold to start doing a physical activity in a senior association can be easier to overcome than in other organizations.Here different types of recruitment strategies will be needed to recruit different target groups.As West et al. (21) discuss, other forms of marketing could be a strategy for recruiting and finding new target groups.However, as Wong et al. (51) state, it is not just marketing strategies that are needed; there is also a need for resources for local organizations directly promoting older adults' participation in sport and physical activity.
Another recommendation for lowering the threshold to dropin is to design different forms of sport and physical activity for the quite heterogeneous group of older adults, not only when it comes to which sport, but also focus, organization and booking opportunities.How an activity is booked could make it more or less easy for different people to drop in to an activity.Finding different recruitment strategies could then potentially increase diversity and reduce social inequality in sport and physical activity (24).
A third recommendation related to drop-in is to start with short-term projects as a springboard into ongoing activities.The focus in this study was on the ongoing activities, but to increase drop-in for specific groups, or when testing a new form, short-term initiatives can be a complement.It is then important to make a short-term initiative sustainable, for example, by cooperating with other actors, such as outdoor associations, the scouts, and pensioners organizations (dropover), or having a strategy for keeping participants within the organization (drop-through).Drop-through concerns recommendations for how to lower the threshold for older adults to change activities within an organization.One of our main findings in this study is that age is significant for which activity older adults participate in.Hence, there should be an opportunity for older adults (and others) to change their form of activity within the same organization, for example from medium-high intensity to low, using a golf cart but still playing golf, or doing walking football instead of football.Changing the form of sport and physical activity can be done while maintaining the social relations that older adults have built up and which most of them find to be a meaningful aspect of participating (14).
Here, a life-course perspective on how to organize sports is recommended (23,54,55).In line with our findings that older adults often reveal that they have been members for a long time and were recruited by internal contacts, such as when their children started or even earlier, planning for drop-through could be a successful strategy.In these features we see possibilities for the organizations to also work with external recruiting in the future, with the aim of reaching a broader public that is less familiar with the settings of sport clubs or physical activity initiatives.
Drop-over concerns recommendations for how to lower the threshold for older adults to change from one organization to another.Cooperation between different organizations, for example between a summer and a winter sport, or a senior association and a sport club, could be very beneficial for older adults.Cooperation with other senior associations (also for health care) is also emphasized as an important way of recruiting and communicating in other studies (21,23,24).Geographical considerations, like living in the countryside or in a city, can further affect whether the need for a drop-over alternative is even greater than for drop-through, depending on the size of the organization or the number of organizations in the neighbourhood.It is important to take a holistic approach to the question of increasing drop-in and reducing drop-out among the older adult members.

Limitations and strengths
We have, of course, some reflections on the choices we have made during this journey.For this study we developed a new questionnaire, the SPAHRQ, which of course may have some teething pains.One limitation is that we did not have a question on how long the respondents had been active participants in any sport; we only asked about their current activity.It would have been interesting to compare those.On the other hand, the SPAHRQ was developed from an in-depth theoretical framework for asking questions in a certain way to convey salutogenic theory (29), which contributes to deepening the knowledge about both organizational and individual factors and the relation between them.
We also developed the organizational category pairs of organizer, focus, organization and intensity, inspired by Eime et al. (56) mode, type and setting.In the future it would be interesting if more categories could be developed to explore different characteristics of sport and physical activity initiatives, both for older adults and others, as well as in different contexts.Another sample, which also included for example private gyms with organized physical activity, might have further deepened our results, and this could also be developed in future studies.
Another limitation may be the self-rated data.In some studies, participants tend to overrate time spent in physical activity per week (57).This is a minor problem, however, in this type of study, where the aim of this variable is mostly to describe who the participants are.In this study it also does not matter that the participants are a quite homogeneous group, because the focus is on ongoing initiatives and how these could be organized, and the participants in them are the way they are.Of course, we know that these are very healthy older adults with good preconditions to participate in sport and physical activity.

Conclusion
Individual-level recommendations for how much physical activity people in different ages should perform to gain health benefits are not enough to get older adults to participate in different sport and PA initiatives.In this study, we have proposed some recommendations for how organizations could organize activities to suit as many people as possible for as long as possible.
When considering recommendations like these, with a specific focus on older adults, we conclude that older adults want similar outcomes when participating in sport and physical activity, but that they seek this in different ways.To attract as many older adults as possible, organizations should accordingly work with lowering the threshold into sports and physical activity, as well as within and between different sports and physical activities, in order to raise the threshold to dropping out of sport and physical activity (58, 59).
