百米比赛是径赛中速度最快的项目之一,它是在人体大量缺氧状况下持续高速度跑的极限强度运动。人体运动时,能量消耗明显增加,增加的情况决定于运动的强度和持续运动的时间。研究百米运动员全程跑中肌肉工作的供能特点,可以为科学地制定训练原则、训练计划和选择训练手段提供重要理论依据。1 能量代谢的基础理论 肌肉收缩是需要能量的,肌肉中储存有多种能源物质,其中重要的有三磷酸腺苷 The 100-meter race is one of the fastest programs in the track and it is the ultimate strength exercise that continues to run at high speeds in the body under a lot of hypoxia conditions. When the human body exercises, the energy consumption obviously increases, the increase situation depends on the exercise intensity and the continuous movement time. Studying the energy supply characteristics of 100-meter-long athletes’ running muscles can provide important theoretical basis for scientifically formulating training principles, training plans and selecting training methods. A basic theory of energy metabolism Muscle contraction is the need for energy, the muscle stores a variety of energy substances, of which there is an important adenosine triphosphate
