Effects of hormonal contraception and the menstrual cycle on fatigability and recovery from an anaerobic exercise test. J Strength Cond Res 38(7): 1256-1265, 2024-This study sought to evaluate the effects of oral contraceptive (OC) and hormonal intrauterine device (H-IUD) use, compared with a eumenorrheic (EUM) cycle, on fatigability and recovery between hormone the phases. Peak power (PP), average power (AP), fatigue index (FI), blood lactate, vessel diameter, and blood flow (BF) were measured from a repeated sprint cycle test (10 × 6 seconds) in 60, healthy, active women (mean ± SD ; age: 26.5 ± 7.0 years, BMI: 22.5 ± 3.7 kg·m -2 ) who used monophasic OC (≥6 months; n = 21), had a H-IUD (≥6 months; n = 20), or had regular naturally occurring menstrual cycle (≥3 months) or had a nonhormonal IUD (EUM; n = 19). Subjects were randomly assigned to begin in either the low-hormone phase (LHP) or high-hormone phase (HHP) and were tested once in each phase. Separate univariate analyses of covariances assessed the change from HHP to LHP between the groups, covaried for progesterone, with significance set at p ≤ 0.05. All groups demonstrated similar changes in PP, AP, FI, blood lactate, vessel diameter, and BF between the phases ( p > 0.05). Although not significant, AP was higher in LHP for OC (Δ -248.2 ± 1,301.4 W) and EUM (Δ -19.5 ± 977.7 W) and higher in HHP for H-IUD (Δ 369.3 ± 1,123.0 W). Oral contraceptive group exhibited a higher FI (Δ 2.0%) and reduced blood lactate clearance (Δ 2.5%) in HHP. In recreationally active women, hormonal contraception and hormone phases may minimally impact fatigue and recovery. Individual elite female athletes may benefit from understanding hormonal contraception type as performance and recovery may slightly vary across the cycle.

■Cabre,他,Ladan,AN,摩尔,SR,乔尼亚克,KE,蓝色,MNM,Pietrosimone,BG,哈克尼,AC,还有史密斯-瑞安,激素避孕和月经周期对疲劳性和无氧运动试验恢复的影响。JStrengthCondRes38（7）：1256-1265，2024-本研究旨在评估口服避孕药（OC）和激素宫内节育器（H-IUD）使用的效果，与Eumorrhic（EUM）循环相比，关于激素阶段之间的易疲劳性和恢复。峰值功率(PP),平均功率(AP)疲劳指数（FI），血乳酸，血管直径,和血流量（BF）从重复的冲刺周期测试（10×6秒）在60，健康，活跃女性（平均值±SD；年龄：26.5±7.0岁，BMI：22.5±3.7kg·m-2）使用单相OC（≥6个月；n=21），有H-IUD（≥6个月；n=20），或有规律的自然月经周期(≥3个月)或有非激素IUD(EUM;n=19)。将受试者随机分配到低激素阶段（LHP）或高激素阶段（HHP），并在每个阶段测试一次。对协方差的单独单变量分析评估了组间从HHP到LHP的变化，黄体酮共变，显著性设置为p≤0.05。所有组表现出相似的PP变化，AP,FI,血乳酸，血管直径,和阶段之间的BF(p>0.05)。虽然不重要，OC（Δ-248.2±1,301.4W）和EUM（Δ-19.5±977.7W）的LHP较高，H-IUD的HHP较高（Δ369.3±1,123.0W）。口服避孕药组在HHP中表现出更高的FI（Δ2.0％）和降低的血乳酸清除率（Δ2.5％）。在娱乐活跃的女性中，激素避孕和激素阶段可能对疲劳和恢复的影响最小。个别精英女运动员可能会受益于了解荷尔蒙避孕类型，因为整个周期的表现和恢复可能略有不同。
