Twenty-five athletes were selected to receive three kinds of loads (endurance, strength and sprint training) at the same training time, as well as to receive the same kind of load at different time (morning, am. pm), then the tricarboxylic acid (TCA) cycle products, free fatty acids (FFA), urea nitrogen, creatinine and free amino acids contents in their serum were measured. The results showed that at the same training time, different loads led to different physiological effects, while the same kind of exercise training resulted in more protein catabolism in p.m. than in the morning or a.m. Endurance or training in the morning had considerable influence on the levels of TCA cycle products and FFA components. Training in p. m. may be favourable to improving the quality of the sports of speed and strength.
选取25名运动员，让他们在同一训练时间接受三种负荷（耐力、力量和短跑训练），并在不同时间（上午、下午）接受同一种负荷，然后测量他们血清中的三羧酸（TCA）循环产物、游离脂肪酸（FFA）、尿素氮、肌酐和游离氨基酸含量。结果表明，在同一训练时间，不同负荷会导致不同的生理效应，而同一类型的运动训练在下午比上午或中午会导致更多的蛋白质分解代谢。耐力训练或上午训练对TCA循环产物和FFA成分水平有相当大的影响。下午训练可能有利于提高速度和力量运动的质量。
