The effect of a strength training program on affect, mood, anxiety, and strength performance in older individuals
MetadataShow full item record
The purpose of this study was to evaluate the effect of a strength training program on anxiety, affect, and mood in a group of older adults (≥ 65 years). Twenty men and women participated in a 12-week strength training program. Participants were randomized to an intervention and a waiting list control group. Results showed a significant improvement in the intervention group’s strength scores. Trait anxiety showed a decline in both groups. When mood profiles of participants were analyzed across the initial 12-week of the study, a dimension of mood called Vigor-Activity significantly decreased in the control group while the intervention group’s scores did not change. The affect data showed that negative affect decreased significantly in the intervention group following the training protocol. This study indicates that 12 weeks of strength training results in significant muscle strength increases and moderate improvements of the overall psychological profile.
