| The purpose of this study was to ascertain the psychosocial and fitness benefits provided by an indoor cycling program for cancer survivors. Specifically, we hypothesized that indoor cycling would result in reduced mood disturbance, anxiety and depression, and in turn would enhance overall quality of life (QOL). It was also hypothesized that these findings would be stronger within a group of cancer patients with control over their activity versus those who had less control. Specifically, subjects were divided into three groups, based on different levels of control within the exercise program. Analyses of group differences on the primary outcomes of QOL, anxiety, depression and aerobic capacity from pre to post test, as well as at a 2-month follow-up, showed no statistically significant results, but trends were evident. Overall, the moderate perceived control (MPC) group saw improvements in QOL, mood, anxiety and aerobic capacity from pre- to post-intervention. Changes from post- to follow-up showed few changes within the MPC group. In our secondary analysis, we proposed differences between groups in exercise behaviour and intention due to the manipulation of perceived control over elements within the exercise intervention. The theory of planned behaviour (TPB) was used to investigate these hypotheses. Due to the small sample size, the influence of perceived control on physical activity intentions and actual behaviour was only examined on a preliminarily basis. Trends were evident, but statistical significance was not found in most measures. However, intention was significantly correlated with confidence, social support, and attitude, indicating initial support for the use of the TPB for developing an intervention with cancer survivors. |
