Two studies were conducted to examine the relationship between class cohesi
on and exercise adherence in older adult exercisers. Study I examined the p
redictive ability of four dimensions of cohesion on exercise participation
at 1, 6, and 12 months following the initial assessment of cohesion. Study
2 examined the effectiveness of a team-building intervention, designed to e
nhance class cohesion (and based on Study 1 results), on improving exercise
adherence and return rates. Participants were assigned to a team-building,
placebo, or control condition. Study 1 showed that three measures of cohes
ion, Individual attractions to the group-social, Group integration-social,
and Group integration-task, were all significantly related to exercise clas
s attendance following a 1-month interval. Group integration-task was signi
ficantly related to class attendance following a 6- and a 12-month interval
. Study 2 showed that participants in the team-building condition (a) atten
ded more classes than the control and placebo conditions and (b) had a high
er return rare following a 10-week hiatus than the control condition. It wa
s concluded that (a) class cohesion plays a significant role in exercise cl
ass participation, both short- and long-term, and(b) samples of older adult
exercisers are appropriate groups for interventions based on developing cl
ass cohesion.
