Purpose:
To determine whether performance accomplishment and perceived exertion predict change in self-efficacy following a single strength training session and whether change in self-efficacy predicts subsequent motivation to join a strength training program.
Methods:
Fifty-nine sedentary older adults participated in a single strength training session at a seniors' exercise center, completed measures of perceived exertion and self-efficacy, and received a voucher for a free fitness consultation.
Results:
Regression analyses indicated that perceived exertion predicted change in self-efficacy. In turn, greater change in self-efficacy was associated with a greater likelihood of using the voucher for a fitness consultation.
Discussion:
Sedentary older adults can be motivated toward joining a strength training program after an initial strength training session that required low exertion. Practitioners could increase strength training initiation by providing such experiences.
