This study explored the fatigue effect on postural control (PC) across menstrual cycle phases (MCPs) in female athletes. Isometric maximal voluntary contraction (IMVC), the center of pressure sway area (CoParea), CoP length in the medio-lateral (CoP) and antero-posterior (CoP) directions, and Y-balance test (YBT) were assessed before and after a fatiguing exercise during the follicular phase (FP), mid-luteal phase (LP), and premenstrual phase (PMP). Baseline normalized reach distances (NRDs) for the YBT were lower ( = 0.00) in the PMP compared to others MCPs, but the IMVC, CoParea, CoP, and CoP remained unchanged. After exercise, the IMVC and the NRD decrease was higher at PMP compared to FP ( = 0.00) and LP ( = 0.00). The CoParea, CoP, and CoP increase was higher in the PMP compared to FP ( = 0.00) and LP ( = 0.00). It was concluded that there is an accentuated PC impairment after exercise observed at PMP.
本研究探讨了疲劳对女运动员月经周期各阶段姿势控制（PC）的影响。在卵泡期（FP）、黄体中期（LP）和经前期（PMP）的疲劳运动前后，评估了等长最大自主收缩（IMVC）、压力中心摆动面积（CoParea）、压力中心在内外侧（CoP）和前后方向（CoP）的长度以及Y平衡测试（YBT）。与其他月经周期阶段相比，PMP期YBT的基线标准化伸展距离（NRDs）更低（ = 0.00），但IMVC、CoParea、CoP和CoP保持不变。运动后，与FP期（ = 0.00）和LP期（ = 0.00）相比，PMP期IMVC和NRD的下降幅度更大。与FP期（ = 0.00）和LP期（ = 0.00）相比，PMP期CoParea、CoP和CoP的增加幅度更大。研究得出结论，在PMP期运动后观察到姿势控制受损加剧。
