Modification of the Forms of Self-Determined Regulation and Quality of Life after a Cardiac Rehabilitation Programme:...

The objective is to analyse and compare the effects of an adapted tennis cardiac rehabilitation programme and a classical bicycle ergometer-based programme on the type of motivation towards sports practice and quality of life in patients classified as low risk after suffering acute coronary syndrome.

The Behavioural Regulation in Exercise Questionnaire (BREQ-2) and Velasco's Qualityof Life Test were applied. The sample comprised 110 individuals (age = 55.05 ± 9.27) divided into two experimental groups (tennis and bicycle ergometer) and a control group.

The intra-group analysis showed a significant increase between pre- and post-test results in intrinsic regulation in the tennis group and in the control group. In identified regulation, the bicycle ergometer group presented significant differences from the control group. On the other hand, in the external regulation variable, only the tennis group showed significant differences, which decreased. Significant improvements in all quality-of-life factors when comparing the pre-test period with the post-test period were only found in the experimental groups. As per the inter-group analysis, significant differences were observed in favour of the tennis group with respect to the control group in the variables of health, social relations and leisure, and work time as well as in favour of the bicycle ergometer group compared with the control group in the variables of health, sleep and rest, future projects and mobility. No significant differences were found in any of the variables between the tennis group and the bicycle ergometer group.

It is relevant to enhance the practice of physical exercise in infarcted patients classified as low risk as it improves the forms of more self-determined regulation towards sporting practice and their quality of life.
