中文摘要:
      目的:通过测试上海市处于不同生长发育阶段青少年游泳运动员的血清睾酮水平,比较各发育阶段血清睾酮水平的差异,探讨基层教练员利用青少年生长发育的不同阶段来预测睾酮水平的可行性。方法:对420名青少年游泳运动员进行左手正位X线片的拍摄和血清睾酮的检测,按骨龄片中种籽骨形态的差异进行不同发育阶段的分组,从各组中随机抽取30人作为研究对象,男、女运动员分别进行组间血清睾酮水平的比较。结果:不同发育阶段男、女青少年游泳运动员的血清睾酮水平均存在显著性差异(P<0.01);男运动员发育后阶段血清睾酮值是发育中和发育前的186%和1 187%,女运动员发育后阶段血清睾酮值是发育中和发育前的155%和329%;男运动员的睾酮水平与肌肉含量存在显著性正相关(r=0.875,P<0.01),与体脂百分比存在显著性负相关(r=-0.312,P<0.01);女运动员的睾酮水平与肌肉含量、体脂百分比均存在显著性正相关(r=0.774和0.463,P<0.01)。结论:男、女青少年游泳运动员整个生长发育阶段血清睾酮水平都处于显著增加的趋势,且每个生长发育阶段,血清睾酮水平都具有明显的阶段特征;男、女运动员的血清睾酮水平对身体成分会产生影响,且存在性别特征。
英文摘要:
      Objective: The study is to test the serum testosterone level of young swimmers at different pubertal stages in Shanghai, and to compare the difference of serum testosterone concentration at every stage, and to investigate the feasibility of using different adolescent pubertal stages to predict serum testosterone concentration. Methods: The left hands were X-rayed and the serum testosterone concentrations were tested among 420 young swimmers. The swimmers were divided into groups according to different seed bone morphology in bone age film, and then 30 athletes were selected randomly from each group as the subjects. Serum testosterone levels were compared among final groups of male and female athletes respectively. Results: There were significant differences in serum testosterone concentration at different pubertal stages between male and female athletes (P<0.01). The serum testosterone level of male athletes at the post-development stage was 186% and 1187% of those during and before development respectively, and 155% and 329% for females. The testosterone level of male athletes was positively correlated with muscle mass (r=0.875, P<0.01), negatively correlated with body fat percentage (r=-0.312, P<0.01), but both positively correlated for female athletes (r=0.774 and 0.463, P<0.01). Conclusion: The serum testosterone concentration of male and female swimmers in the whole pubertal stage has a significant increasing trend, and the serum testosterone has obvious change at each stage of growth and development. Serum testosterone level has an impact on the body composition for both male and female athletes, and has gender differences as well.
