Background/Objective. Physical exercise plays a key role in the prevention and prognosis of chronic diseases.Despite this evidence, a low percentage of patients regularly perform physical activity.A better understanding of the variables associated with poor adherence may help to develop some strategies to encourage people to participate in exercise interventions.This study investigated the factors influencing adherence to an Adapted Physical Activity (APA) program in subjects suffering from Acute Coronary Syndrome (ACS) clinically stable, Type 2 diabetes, or metabolic syndrome.Secondary end point was to test the efficacy of the exercise training on fitness parameters (VO2, Speed and Time) by 1 km test.Methods.The program was planned in two phases.Phase 1: individual and supervised training free program for 4 weeks; Phase 2: paid training supervised program involved small groups of 4-6 participants for 8 weeks.Results.117 patients (50-64 years, 49 men and 68 women) started the APA program, but only 32 patients (17 men and 15 women) completed phase 2. As collected during telephone interviews, the main factors that influenced adherence including health status, work commitments or family problems.Regarding the physical efficacy, an improvement of the three fitness parameters was observed in the 32 patients who completed the 12 weeks of the APA program.Conclusions.The identification of factors that can influence adherence to exercise programs is the first step in planning and improving health interventions.These parameters have an important public health interest.
