【摘要】：目的研究健美操训练对女大学生跟骨密度及性激素的影响。方法选择湖北第二师范学院参加体育课学习的女大学生60名,随机抽取30名组成试验组进行健美操训练,剩余30名组成对照组进行正常体育教学,分析两组学生跟骨密度及性激素的差异。结果训练后试验组学生雌二醇(E2)为(51.3±2.0)ng/L、跟骨密度为(108.62±15.17)g/cm2,对照组分别是(46.5±1.9)ng/L和(98.66±14.34)g/cm2,试验组高于对照组(P0.05);试验组学生训练后E2显著高于训练前(P0.05)。对照组学生训练期间骨密度变化平缓(P0.05);试验组学生跟骨密度于训练开始至第7周缓慢上升,第7周至第9周之间略下降,第9周至第11周突升,此后缓慢上升,于第11周开始跟骨密度与训练前差异有统计学意义(P0.05)。结论健美操训练有利于增强跟骨密度,促进E2分泌。
[Abstract]:Objective to study the effect of calisthenics training on bone mineral density (BMD) and sex hormone of female college students. A total of 30 subjects were randomly selected for aerobics training in the experimental group, while the remaining 30 subjects in the control group were trained in normal physical education. Results after training, estradiol E _ 2 was 51.3 卤2.0 ng / L in the experimental group. The BMD was 108.62 卤15.17g / cm ~ 2 in the control group, 46.5 卤1.9 ng / L and 98.66 卤14.34 g / cm ~ 2 in the control group, respectively. The test group was higher than the control group (P 0.05). After training, E2 in the experimental group was significantly higher than that in the pre-training group (P 0.05). In the control group, the bone mineral density (BMD) of the control group was significantly higher than that of the control group (P 0.05). The BMD of the experimental group increased slowly from the beginning of training to the 7th week, decreased slightly from the 7th week to the 9th week, rose suddenly from the 9th to the 11th week, and then increased slowly. There was significant difference between bone mineral density (BMD) and pre-training at the 11th week (P 0.05). Conclusion Aerobics training is beneficial to enhance bone mineral density and E2 secretion.
