背景：研究报告女性长跑运动员骨密度低。目的：研究大学女生长跑运动员抗阻训练干预前后骨密度和血清激素（包括脱氢表雄酮硫酸酯（DHEA-S）和雌二醇（E2））的变化。方法：14名女大学长跑运动员（年龄，19.8 ± 0.8岁）和14名年龄匹配的健康年轻女性作为对照（年龄，20.5 ± 1.6岁），并分为RT组和对照组（RT组，RRT;跑步者对照组，RCON;非运动员RT组，NRT;非运动员对照组，NCON）。RRT组和NRT组在60- 85%1RM负荷下进行蹲下和硬拉，每次五组，每周两次，持续16周。采用双能X线骨密度仪测量全身、腰椎L2 ~ L4和股骨颈的骨密度。测定静息血清皮质醇、促肾上腺皮质激素、睾酮、生长激素、胰岛素样生长因子1、DHEA-S、孕酮、E2、I型前胶原N端前肽（P1 NP）和N端肽。结果：RRT组和NRT组的全身BMD均显著增加（P
BACKGROUND: Studies report low bone mineral density (BMD) in female distance runners. We aimed to investigate changes in BMD and resting serum hormones, including dehydroepiandrosterone sulfate (DHEA-S) and estradiol (E2), before and after resistance training (RT) inter-ventions in female collegiate distance runners. METHODS: Fourteen female collegiate distance runners (age, 19.8 +/- 0.8 years) and 14 age-matched healthy young women as controls (age, 20.5 +/- 1.6 years) were included and divided into RT groups and controls (runner with RT, RRT; runner controls, RCON; non-athlete with RT, NRT; non-athlete controls, NCON). The RRT and NRT groups performed squats and deadlifts at 60-85% 1RM load for one session of five sets of five repetitions, twice a week for 16 weeks. BMD of the total body, lumbar spine L2-L4, and femoral neck was measured by dual-energy X-ray absorptiometry scanning. Resting serum cortisol, adrenocorticotropic hormone, testosterone, growth hormone, insulin-like growth factor 1, DHEA-S, progesterone, E2, procollagen type I N-terminal propeptide (P1NP), and N-terminal telopeptide were assayed. RESULTS: The results showed a significant increase in total body BMD in both the RRT and NRT (both P
