Examining Group Components On Exercise Adherence In Older Adults, Brody Polk

Masters Theses

Older adults remain the least active population despite the well-known benefits of regular exercise (Beauchamp et al., 2007; Rúa-Alonso et al., 2023). Researchers examining exercise adherence in older adults have determined two modalities of training—individual and group—with individual training being the preferred mode of exercise for older adults (Beauchamp et al., 2007). However, previous research has failed to evaluate the various components of group exercise before making a comparison with individual exercise to determine which form best predicts older adults’ adherence to exercise (Hawley-Hague et al., 2014). As such, the purpose of the current study was to examine the effects …
