This study examined exercise-adherence rates and their predictors across 21 randomized controlled trials (RCTs) involving older adults (age ≥ 55 years). On average, participants completed 78% of their prescribed exercise bouts. Adherence tended to be greater in strength- and flexibility-exercise training programs (M = 87%) than in aerobic-exercise training programs (M = 75%). The best adherers were individuals who were fitter at baseline, had a history of a physically active lifestyle, were nonsmokers, and had higher exercise self-efficacy. Different variables predicted adherence (a) at different time points in a RCT. (b) to different types of exercise, and (c) to different aspects of the exercise prescription (i.e., frequency, intensity, and duration). The findings suggest that older adults might be more adherent to exercise prescriptions than younger adults are. There is also a need for more theory-based research to examine predictors of adherence to various aspects of the exercise prescription.

This study examined whether information about an individual’s exercise habits influences the impressions that others form of the individual. Using a 2 (target’s gender) × 3 (target’s exercise status) design, 627 men and women participants read a description of a young man or woman who was described as an exerciser, nonexerciser, or control. Participants then rated the target on 12 personality and 8 appearance dimensions. Analyses revealed significant main effects for both independent variables (p < .05). Nonexercisers received lower ratings than the exercisers and/or controls did on virtually all the dimensions (p < .05), and female targets were rated more favorably than male targets were on several dimensions (p < .05). The interaction between a target’s exercise status and gender was not significant. The results suggest that for women, as well as men, there are self-presentational benefits associated with being an exerciser and self-presentational liabilities for those who are nonexercisers.

This study used a between-subjects design to examine the effects of exercise attire on older women’s feelings toward exercise groups and their self-presentational efficacy (SPE). Eighty-one older women (mean age = 70.9 years) watched a 2-min videotape showing an exercise group of older adults who were dressed in either revealing exercise attire (sleeveless T-shirts and shorts) or nonrevealing attire (short-sleeved T-shirts and long trousers). Overall there was no difference in participants’ feelings toward the 2 exercise groups, but women who were more physically active had more positive feelings toward the revealingly attired group than did women who were less active (p < .01). Similarly, there was no main effect for exercise attire on women’s SPE, but after watching the revealingly attired exercisers, women with higher social physique anxiety (SPA) reported lower SPE than did women with lower SPA (p < .05). These results suggest that for some women, the attire worn by an exercise group can affect their feelings about the group, as well as about themselves.
