摘要: Abstract Background: We investigate the effects of 17β-Estradiol across phases menstrual cycle on laxness anterior cruciate ligament (ACL) and neuromuscular control patterns around knee joint in female runners. Methods: Twelve healthy runners who reported normal cycles for previous 6 months were tested twice one complete serum levels 17β-estradiol, laxity (KJL). Electromyographic (EMG) activity quadriceps hamstrings muscles was also recorded during running a treadmill. The changes EMG activity, KJL, hormonal concentrations each subject follicular ovulatory cycle. Results: An observed increase KJL response to peak estradiol phase associated with increased preactivity hamstring muscle before foot impact (p<0.001). A consistent pattern firing recr...
