Impact of student-led community-based group exercise on strength and balance in older adults

Abstract Age-related declines in strength and balance can negatively affect physical function and independence in older adults. Community-based, student-led exercise programs have been suggested to improve physical function and address barriers to physical activity in this population. This study aimed to evaluate the effectiveness of a student-led, community-based group exercise program in improving strength and balance in older adults. A quasi-experimental pretest-posttest study was conducted across two independent cohorts with pooled analysis performed at a senior center, where Doctor of Physical Therapy students led an eight-session, multicomponent exercise program . Functional outcomes were assessed pre- and post-program using grip strength, the 30-second sit-to-stand (30STS) test, and the Timed Up and Go (TUG) test. A total of 29 participants completed the program across two cohorts. Statistically significant improvements were observed in functional strength and balance, with 30STS repetitions increasing by 34.9% ( p < 0.001) and TUG times decreasing by 1.5 s ( p < 0.001). No significant change was noted in grip strength ( p > 0.05). These findings support the feasibility and potential effectiveness of student-led group exercise programs for promoting functional improvements in older adults within community settings. Further research is warranted to confirm these outcomes in larger, randomized controlled trials.
