Effects of rope skipping exercise on physical, cardiovascular fitness and exercise tolerance in adolescent students with moderate intellectual disability

Abstract

AbstractBackgroundAdolescents with intellectual disabilities (ID) who live a sedentary lifestyle may lead to an increased risk of chronic cardiovascular disease in adulthood. The aim of this study is to investigate the effects of 8‐week progressive rope skipping training on physical, cardiovascular fitness and exercise tolerance of high school students with moderate ID.MethodsThirty‐four senior high school with ID (aged 15–18 years old) were randomised into experimental group received progressive skipping rope exercise (RS, n = 17) and control group no rope skipping exercise intervention group (CON, n = 17). The RS group were received progressive rope skipping exercise for 50 min each time, three times a week, for 8 weeks. The control group was not allowed to participate in intervention activities during the study period. The physical fitness, body composition, arterial stiffness index (ASI) and blood pressure were measured before and after the 8‐week intervention.ResultsAfter the 8‐week progressive skipping rope exercise intervention, the participants from the RS group increased in the 3‐min step test, sit‐up test, grip strength and sit and reach test, when compared to the baseline (P < 0.05). The RS group exhibited lower the area under curve of heart rate (HR) during post‐exercise recovery (P < 0.05). The participants in the RS group showed significant decreases in systolic (SBP) and diastolic (DBP) blood pressure, mean arterial pressure (MAP) and HR when compared to the baseline (P < 0.05). Change SBP has moderate positive correlation with change ASI.ConclusionsThe results of this experiment suggest that progressive rope skipping exercise might improve physical fitness and promote cardiovascular health, as well as enhance exercise tolerance for adolescent students with moderate ID.
