The fields of biomechanics and gerontology have significantly advanced our understanding of physiological alterations accompanying human aging. Aging is characterized by progressive declines affecting various systems, including the nervous system, muscle-tendon units, and joint and bone structures, which collectively lead to impairments in physical health, motor control deficits, and increased risk of functional limitations. These age-related structural and functional deteriorations, initially subtle, can gradually progress from mild functional impairment to a state of significant incapacity and even prolonged bed rest. With global life expectancy continually rising, the proportion of the world's population above 60 years is projected to significantly increase, making it imperative to address the escalating burden on healthcare systems and promote aging individuals' quality of life through innovative, evidence-based interventions. Recent research underscores the effectiveness of non-pharmacological approaches—particularly physical exercise, nutrition, and technology-driven interventions—in mitigating these biomechanical and physiological consequences of aging.
This Research Topic aims to consolidate current knowledge and emerging evidence regarding the biomechanics of aging and the effectiveness of exercise as well as other targeted non-pharmacological interventions for promoting physical functionality and overall well-being among older adults. The primary objectives include investigating biomechanical adaptations associated with aging, evaluating clinical outcomes of exercise programs, nutritional strategies, and technological interventions, and identifying the most comprehensive and evidence-supported pathways to maintain or enhance older adults' physical capacities, independence, and quality of life. Specific emphasis will be placed on clinical evidence of intervention effectiveness in both healthy older populations and those experiencing common age-related health challenges (cardiovascular, neurological, respiratory, immunological, musculoskeletal, among others). By situating this exploration within a public health framework, we seek to discuss the broader implications for public health approaches to exercise, nutrition, and related interventions.
To comprehensively explore interventions aimed at improving biomechanics and well-being in older populations, the scope includes studies addressing healthy or health-challenged older adults. Contributions are encouraged in, but are not limited to, the following thematic areas:
• Biomechanical adaptations in aging populations
• Effects of physical exercise interventions on older adults' biomechanics and health
• Nutritional interventions combined with physical activity to enhance functional outcomes in older individuals
• Kinematic and kinetic movement analysis in older adults
• Gait and postural control strategies in aging adults
• Morphological and mechanical alterations of muscle-tendon units during aging
• Joint and bone morphology changes and their biomechanical consequences in aging adults
• Biomechanical characterization of muscle-tendon diseases and injuries related to aging
• Biomechanics associated with joint and bone degeneration, diseases, and injuries among older populations
• Biomechanical analyses of nutritional and exercise interventions for older individuals
• Application of innovative technological interventions, such as wearable assistive devices, for enhancing mobility, and quality of life among older adults
This Research Topic will provide critical insights into developing public health strategies that effectively support the aging population's well-being and physical health.
