青少年运动员心肌耗氧指数(RPQ)及心功指数在性别、项目间有明显差异。男子高于女子;龙舟、潜泳、游泳等项目的运动员RPQ指数及心功指数均较高,力量速度性项目如柔道、拳击、跳投类和足球运动员的RPQ指数较高而心功指数较低;速度耐力性项目如中长跑、篮球等的RPQ指数较低而心功指数较高。RPQ指数及心功指数的变化也与训练水平有关。RPQ指数和心功指数是反映心脏能量消耗及心脏做功的简易指标,对体育训练及运动员选材是有意义的。
Adolescent athletes myocardial oxygen consumption index (RPQ) and cardiac function index in the gender, there are significant differences between the items. Men are higher than women; athletes with dragon boat, snorkeling, swimming and other items have higher RPQ index and heart function index, while strength-speed items such as judo, boxing, jump jumpers and footballers have higher RPQ index and lower heart function index; Speed endurance projects such as middle and long distance, basketball and other RPQ index lower and higher cardiac index. RPQ index and heart function index changes with the training level. RPQ index and cardiac function index is a simple indicator of cardiac energy expenditure and cardiac work, which is meaningful for sports training and selection of athletes.
