Exercise Adherence and Cardiovascular Health

Behavioral - Imposed-MICT

Moderate-Intensity Continuous Training (MICT) is continuous exercise for 30 min/session at 60-65% of heart rate max for 5 times/week, consistent with the physical activity guidelines of 150 min/week of moderate activity. Individuals are asked to engage in MICT exercise only (IM-MICT) during the supervised and unsupervised exercise sessions. During the supervised exercise the intensity will be based on the HR monitors, and affective and psychophysiological responses of perceived exertion. The exe ...read more on ClinicalTrials.org

Behavioral - Imposed-HIIT

Individuals randomized to IM-HIIT will be asked to engage in High-Intensity Interval Training (HIIT) exercise only, which is 5 repeated vigorous intervals of 1-min duration at 85-90% of heart rate max with 1-min recovery periods, with 3-min warm-up and 2-min cool-down. Total session duration is 15 min for 5/week and it matches the guidelines of 75 min of vigorous exercise per week. During the supervised and unsupervised exercise sessions participants will perform a 15 min bout of HIIT. During th ...read more on ClinicalTrials.org

Behavioral - CHOICE

Participants will first be familiarized with HIIT and MICT in randomized, counter-balanced order and subsequently they will always self-select the exercise type for the supervised and unsupervised exercise sessions. The IM-HIIT and IM-MICT protocols will match to the parallel imposed conditions. During the supervised exercise the intensity will also be based on affective and psychophysiological responses of perceived exertion. Throughout the 3-week intervention as well as during the 12-month fol ...read more on ClinicalTrials.org
