COMBINING DIFFERENT CONCURRENT TRAINING METHODS IN OLDER ADULTS WITH METABOLIC SYNDROME

ABSTRACT Introduction: There are no studies comparing the effects of different concurrent training routines [i.e., a resistance plus high-intensity interval (RT+HIIT) program compared to an RT moderate-intensity continuous (RT+MICT) program] on cardiorespiratory fitness (CRF) and physical performance in older adults with metabolic syndrome (MetS). Objective: This study aimed compare two routines, RT+HIIT versus RT+MICT, CRF MetS. Methods: Thirty-nine participants (67.0±6.7 years age) were randomly assigned into three groups: RT+ MICT, HIIT control group (CON, exercise). The 12-week consisted 3 sessions/week (~50 minutes/session). aerobic component was customized for iso-caloric energy expenditure (P≥0.217) iso-load distribution (TRIMP, P≥0.893), however MICT had longer time (P≤0.01). We evaluated pre- post-evaluation (VO2peak), capacity [power lower limbs (PLL), running velocity, exhaustion], plasma lactate, rate perceived exertion (RPE), resting heart (HRrest), peak (HRpeak). Results: At end intervention, significant increase VO2peak observed only (P=0.01), but CON both RT+MICT groups improvement (P≤0.02). Only HRrest as baseline group. Also, groups, not CON, significantly improved speed, exhaustion, PLL (P<0.05). changes HRpeak, RPE, lactate any groups. Conclusion: Our results suggest that 12 weeks or improve lower-limb performance. our provides additional benefits Level evidence II; Randomized Experimental Study.
