Summary

The increase in the prevalence of cardiovascular diseases (CVD), directly associated with the aging of the population, is a concern for public health in Portugal. Given the high prevalence of risk factors and the increasing number of cases of CD throughout Alentejo, where there is no cardiac rehabilitation (CR) coverage, there is an urgent need for the implementation of a CR program.

CR has evolved over the past decades to multidisciplinary approaches focused on education, individualized training, modification of risk factors, and overall well-being of cardiac patients. Studies suggest that high intensity interval training (HIIT) allows greater patient benefits compared to moderate continuous training (MCT), reversal of DC and increased aerobic capacity in CR patients. This study intends to compare HIIT and MCT interventions investigating direct and indirect associations between informally performed physical activity (AF), sedentary behavior, cardiovascular fitness and quality of life (QoL) among patients enrolled in RC programs in phase III.

Interventions

High Intensity Interval Training Program

The HIIT group performed 4 × 4-minute high-intensity intervals at 85%-95% HRpeak followed by a 1-minute recovery interval at 40% HRpeak, predicted with a supervised graded exercise test on a treadmill with the Bruce protocol. The protocol will include a warm-up of 10 minutes at low moderate intensity (50-70% of HRpeak) and a 3 to 5 minute calm return period at 50% of the HRpeak. The supervised sessions will take place on treadmill, 3 times a week for 6 consecutive weeks. If a session is lost, it will be recovered that week or the following week. Each session will be limited to three participants.

OTHER

Moderate Intensity Continuous Training Program

The MICT protocol (usual care) consisted of a continuous bout of moderate-intensity exercise to elicit 70-75% HRpeak, rating of perceived exertion 3 to 5 (fairly light to somewhat hard), for 27.5 minutes to equate the energy expenditure with the HIIT protocol. The protocol will include a warm-up of 10 minutes at low moderate intensity (50-70% of HRpeak) and a 3 to 5 minute calm return period at 50% of the HRpeak. The supervised sessions will take place on treadmill, 3 times a week for 6 consecutive weeks. If a session is lost, it will be recovered that week or the following week. Each session will be limited to three participants.
