适宜的运动负荷是安全、有效地开展体育锻炼的基础,也是体育教学目标达成的重要保障。体育教师在教学设计中为体育课安排科学合理的运动负荷,可以从“理”、“据”、“标”、“法”四点入手。一、“理”——了解运动负荷安排的生理学原理运动生理学认为体育锻炼是人体不断在运动负荷刺激的作用下发生机体结构和功能适应性变化的过程。因此,科学安排运动负荷的前提是体育教师应该了解与运动负荷相关的生理学知识,尤其是 Appropriate exercise load is safe and effective basis for physical exercise, but also the important goal of physical education reached a guarantee. Physical education teachers in science and education design for physical education courses to arrange a scientific and rational exercise load, from the “rationale”, “according to ”, “standard ”, “law ” four start. First, the “rationale ” - understand the physiological principles of exercise load exercise Exercise physiology that physical exercise is the body constantly under the influence of exercise stress occurs the body structure and function of the adaptive changes in the process. Therefore, the scientific arrangement of exercise load on the premise that physical education teachers should understand the physical load related to exercise, especially
