Abstract

OBJECTIVE:

Using self-determination theory (SDT), we examined relationships between cardiac rehabilitation (CR) participants' perceived autonomy support, motivation for exercise, and exercise behavior.

RESEARCH METHOD/DESIGN:

Male CR outpatients (N = 53; M age = 62.83 +/- 10.78 years). The design was correlational (cross-sectional and prospective), examining relationships between perceived autonomy support and motivation for exercise at Week 4 of CR participation as well as motivation and CR attendance and other indicators of exercise behavior (frequency, duration, total exercise time) at a 1-week follow-up, 10 weeks later.

RESULTS:

Perceived autonomy support was correlated with self-determined motivation, r(53) = .32, p < .05. Self-determined motivation predicted total exercise volume at follow-up, r(53) = .34, p < .05, as well as length of exercise session duration (R(2) = .27; beta = .52, p < .001).

CONCLUSION:

Results support SDT and the potential for autonomy support from interventionists to affect self-determined motivation and exercise behavior of participants involved in CR.
