Development of Exercise Prescription Determined by Load to Muscle Energy Metabolism
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.26 Vol.26】
The purpose of this study was to evaluate the effects of exercise prescription determined by energetic stress elicited to working forearm muscle on endurance performance and oxidative metabolism.
Seven healthy male volunteers participated in the study performed two different types of dynamic grip training either right or left arm: one (INT-30) at 30% maximum voluntary contraction, one contraction every second, 5 times a week for 6 weeks and the other (INT-T) at the intensity determined by the change in muscle pH during incremental exercise test. INT-T and INT-30 improved endurance exercise performance by 22.2% and 23.9%, respectively. INT-T reduced the decrease in muscle pH after training.
This result suggests that INT-T training may create greater improvement in endurance performance in submaximal exercise by reducing muscle acidosis.
