INTRODUCTION:
Multiple-joint exercise tends to be more effective in improving a variety of health outcomes across demographics, and self-efficacy theory can increase self-efficacy in older adults. However, the effectiveness of multiple-joint exercise combined with self-efficacy theory on self-efficacy in elderly people with obesity is unknown. This study measured and compared the self-efficacy changes to multiple-joint exercise (MJ) vs. multiple-joint exercise with self-efficacy theory (MJS) in obese older adults.

METHODS:
The study included 45 obese seniors (MJ group; n = 22, BMI = 25.65±2.61 kg/m2; MJS group; n = 23, BMI =25.91±3.17 kg/m2) aged 60-75 years. MJ consisted of 8 exercises of 2 sets per exercise alternating with resting 1 minute between sets (MJ 60 minutes/day; exercise 40 minutes, warm-up, and cool-down 10 minutes) for 3 day/week. Self-efficacy theory consisted of four primary source: (a) master experiences: giving knowledge of multi-joint exercise; (b) modeling: 30-minute conversation with a model (c) verbal and compliment: encouraging and complimenting; (d) emotional arousal: giving awards for leaders. The MJ group received MJ only, but MJS group received MJ combined with self-efficacy theory. Self-efficacy was assessed by questionnaire.

RESULTS:
Both groups had significantly greater knowledge (pre vs. post; MJS = 5.91±1.8 vs. 8.13±1.3; MJ =6.41±1.3 vs. 7.54±1.7) and self-efficacy for multi-joint exercise knowledge (pre vs. post; MJS = 20.74±3.2 vs. 29.13±1.45; MJ = 21.45±2.0 vs. 28.09±2.2; all p<0.05), but no significant differences were observed following the intervention. After receiving the intervention, both groups recognized an increase in personal efficacy following intervention (pre vs. post; MJS = 27.21±3.4 vs. 29.04±1.3; MJ = 27.68±2.3 vs. 27.86±2.0; all p<0.05), while the MJS group had a greater expectation (29.04±1.3 vs. 27.86±2).

CONCLUSION:
In obese older adults, combining MJ with self-efficacy theory is possible and can be utilized to promote exercise self-efficacy and personal efficacy expectations. Future research is needed to assess the effects of MJS on physical function and blood chemistry in obese elderly people.
