We examined the different effects of body mass index (BMI) level on resistance training during menstrual cycle. Thirty-six female subjects performed resistance training and subjects were divided into three groups: BMIunder, BMInorm, BMIover. Subjects completed 12 weeks of sub-maximal resistance training with 3 sets of 8-12 repetitions. Maximum isometric force test was measured before and after training in the follicular phase (FP) and the luteal phase (LP). Maximum isometric force of whole groups (BMIunder, BMInorm, BMIover) was significantly increased both FP and LP after 12-week resistance training. Maximum isometric force after training and absolute increase value in BMInorm and BMIover were no significantly different between FP and LP. However, significant different of maximum isometric force after training (FP, 79.08±11.60; LP, 84.05±12.38) and absolute increase value (FP, 9.63±5.47; LP, 15.13±6.06) were found between FP and LP just by BMIunder. We suggest that if muscle strength is measured in the FP (LP) before training and then they should be measured same phase, such as FP and LP after training and BMIunder can be influenced muscle strength in LP.
我们研究了体重指数（BMI）水平在月经周期中对阻力训练的不同影响。36名女性受试者进行了阻力训练，受试者被分为三组：低BMI组、正常BMI组、高BMI组。受试者完成了12周的次最大阻力训练，每组8 - 12次重复，共3组。在卵泡期（FP）和黄体期（LP）训练前后测量最大等长肌力测试。经过12周的阻力训练后，所有组（低BMI组、正常BMI组、高BMI组）在卵泡期和黄体期的最大等长肌力均显著增加。正常BMI组和高BMI组训练后的最大等长肌力及绝对增加值在卵泡期和黄体期之间无显著差异。然而，仅低BMI组在卵泡期和黄体期训练后的最大等长肌力（卵泡期，79.08±11.60；黄体期，84.05±12.38）和绝对增加值（卵泡期，9.63±5.47；黄体期，15.13±6.06）存在显著差异。我们建议，如果在训练前的卵泡期（黄体期）测量肌肉力量，那么训练后也应在相同阶段测量，如卵泡期和黄体期，并且低BMI组在黄体期的肌肉力量可能会受到影响。
