Low-Volume High-Intensity Aerobic Interval Training Is an Efficient Method to Improve Cardiorespiratory Fitness After Myocardial Infarction: PILOT STUDY FROM THE INTERFARCT PROJECT.

摘要: PURPOSE To analyze the changes in cardiorespiratory fitness (CRF) and body composition following 2 different (low-volume vs high-volume) high-intensity aerobic interval training (HIIT) programs with Mediterranean diet (Mediet) recommendations individuals after myocardial infarction (MI) compared an attention control group (AC). METHODS Body CRF were assessed before a 16-wk intervention 70 participants (58.4 ± 8.5 yr) diagnosed MI. All received Mediet randomly assigned to AC (physical activity recommendations, n = 14) or one of supervised exercise groups (2 d/wk training): high-volume (40 min) HIIT (n 28) low-volume (20 28). RESULTS Following intervention, no significant seen differences between found any studied variables. Only showed reductions waist circumference HIIT, Δ -4%, P < .05; -2%, .001) improvements 15%, .01; 22%; between-group (attention groups). CONCLUSIONS Results suggest that d/wk) volumes could equally improve Low-volume may be potent time-efficient strategy functional capacity.
