Implications for Exercise Prescription and Health Promotion Using BodyMass Resistance Training with Slow Movement
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.40 Vol.40】
ABSTRACT
【Background】The benefit of body weight resistance exercise with slow movement（BWRE-slow） for muscle function is well-documented, but not for energy metabolism.We aimed to examine physiological responses （e.g., energy expenditure （EE），respiratory exchange ratio （RER）， and blood lactate （La）） during and after BWREslowcompared with EE-matched treadmill walking（ TW）． 【Methods】Eight healthy young men （23.4±1.8years old, 171.2±6.2cm, 63.0±4.8kg） performed Squat, Push-up, Lunge, Heel-raise, Hip-lift, and Crunch exerciseswith BWRE-slow modality: Both the concentric and eccentric phase were set to 3sec.A total of 3 sets（ 10repetitions） with 30 sec rest between sets were performed for eachexercise（ 26.5min）．On another day, subjects walked on a treadmill for 26.5min duringwhich EE during exercise was matched to that of BWRE-slow with the researchercontrolling the treadmill speed manually. 【Results】The time course changes of EE and RER were measured. The EEduring exercise for BWRE-slow （92.6±16.0 kcal for 26.5min） was not significantlydifferent from the EE during exercise for TW（ 95.5±14.1kcal, P=0.36）．BWRE-slowelicited greater recovery EE（ 40.55±3.88kcal for 30-min） than TW（ 37.61±3.19kcal,P=0.029）．RER was significantly higher in BWRE-slow during and 0-5min afterexercise, but became significantly lower during 25-30min after exercise, suggestinggreater lipid oxidation was induced about 30-min after exercise in BWRE-slowcompared with TW. 【Conclusion】We also indicated BWRE-slow has 3.1METs in average which iscategorized into moderate-intensity physical activity.
