从运动生理学的角度来看,运动的频度(即每周锻炼的次数)与锻炼的效果有着直接的关系。一次适量的运动后,对肌肉(如肌糖元的储备)和全身各器官系统的健身效果,可以保持一定的时间(从几个小时到几天),例如,运动后,肌糖元的浓度逐渐增高,在第24小时达到最高点,以后又逐渐减少。所以,最合适的运动频度应该这样掌握,即在前一次锻炼的效果尚未消失之前,进行第二次运动,这样,每次锻炼的健身效果逐渐积累,就能够达到提高体能、增进健康的目的。否则,每次运动之间的间隔时间过长,破坏了运动训练的连续性,就难以取得应有的健身效果,还容易在每次运动后都产生肌肉酸痛、疲劳及某些运动创伤。
From the point of view of exercise physiology, the frequency of exercise (ie the number of exercise sessions per week) is directly related to the effect of exercise. After an appropriate amount of exercise, the muscle (muscle glycogen reserve) and the whole body system of the organism can be maintained for a certain period of time (from a few hours to several days), for example, after exercise, muscle glycogen concentration Gradually increased, reached the highest point in the 24th hour and then gradually decreased. Therefore, the most appropriate exercise frequency should be mastered, that is, before the effect of the previous exercise has not disappeared, the second exercise, so that each exercise gradually increase the fitness effect, you can achieve the purpose of improving physical fitness and health promotion . Otherwise, the interval between each exercise is too long, undermining the continuity of exercise training, it is difficult to obtain the proper fitness effect, but also easy to produce muscle pain after each exercise, fatigue and some sports injuries.
