【Abstract】 In order to reveal the characteristics of androgen metabolism of athletes and the effects of different physical loads on them and to find out the relationship between androgen and physical performance, an analysis of serum testosterone levels of 255 elite Chinese athletes and those of 6 college students before and after physical loading were done in 1984.The results are as follows:1. The average resting value of serum testosterone of 158 elite Chinese male athletes （aged 22±8.3 yr） was 507±149ng/dl. There was no significant difference between athletes and untrained males （5704±156ng/dl） but was lower than the value （600 ng/dl） reported in foreign literature.2. Resting values of serum testosterone of 97 elite Chinese female athletes （aged 224±7.5 yr.） averaged 31.9 ng/dl, significantly lower than those of the untrained females （59±22 ng/dl） and foreign female college students （60 ng/dl）. The serum testosterone concentrations of two tall female athletes （over 2 meters） were very low, being 3.2 and 13.7 ng/dl respectively.3. Six male students（aged 21.34±0.8 yr.） of the Physical Education College performed 30 sec. of Wingate Anaerobic Cycling Test（loads 0.083 kg per kg body weight）.The levels of peripheral venous serum testosterone of all subjects increaed significantly right afterwards（from 447±128 ng/dl to 812±164 ng/dl） and recovered one hour after exercise.4. A temporary increase of serum testosterone levels was observed in four subjects among the five male students running for 1 hour with an intensity of 75% VO₂ max, and after a 24-hr recovery period the testosterone levels of these four students were still lower than the values before running.更多还原
