A secondary objective is to explore factors associated with compliance with the exercise regimens. Previous research has indicated that cognitive-affective-behavioural profile is related to exercise activity in a number of populations including sedentary adults, older adults and patients with cardiovascular disease. As we anticipate that one of the mechanisms by which the cycling will result in an outcome better than the more traditional type of disability tailored exercise program is through greater compliance, this second objective is very relevant. This study will also address the impact of regular exercise on cardio-vascular risk factor profile.
