Menstrual cycle symptoms are common and around two thirds of elite athletes feel that these can have negative impacts on their performance.
イングランドのトップリーグである女子スーパーリーグ(WSL)のサッカー選手は、生理の前に筋肉の怪我をする確率が、生理中の6倍高いと新しい研究が示しています。この研究は、女性サッカー選手の怪我と月経周期を追跡した最初の長期的な調査で、特定の時期に怪我のリスクが増加する可能性を示唆しています。この研究では、選手が月経の前の時期や初期・中期の黄体期に筋肉の怪我をする確率が、月経中の6倍および5倍であることが分かりました。この結果はさらなる研究の必要性を強調しており、女性アスリートをサポートするために大規模な研究が必要です。

Abstract
Purpose
The aim of the study was to assess the influence of menstrual cycle phase on injury incidence, severity and type in elite female professional footballers over three seasons.
Methods
Time-loss injuries and menstrual cycle data were prospectively recorded for 26 elite female football players across three seasons. The menstrual cycle was categorised into four phases using a standardised model: menstruation (phase 1; P1), remainder of follicular phase (phase 2; P2), early luteal (phase 3; P3), and pre-menstrual phase (phase 4; P4). Injury incidence rates (IRR) and ratios (IIRR) were calculated for overall injuries, injury severity, type, contact vs non-contact and game/training.
Results
593 cycles across 13,390 days were tracked during the study and 74 injuries from 26 players were eligible for analysis. When comparing IRR between phases (reference: P1), overall injury rates were highest in P4 (IIRR: 2.30 [95% CI: 0.99-5.34; p = 0.05]). When examining rates by injury severity and type, IRR were also highest in P4 for ≤7 days’ time-loss (4.40 [0.93-20.76; p = 0.06]), muscle-specific (6.07 [1.34-27.43; p = 0.02]) and non-contact (3.05 [1.10-8.50; p = 0.03]) injuries. Muscle-specific (IIRR P3:P1: 5.07 [1.16-22.07; p = 0.03]) and ≤ 7 days’ time-loss (4.47 [1.01-19.68; p = 0.05]) injury risk was also significantly higher in P3. Muscle injuries were the most prevalent sub-type (n = 41). No anterior cruciate ligament injuries were recorded across the monitoring period.
Conclusions
Injury risk was significantly elevated during the luteal phase of the menstrual cycle (P3 and P4) among elite female professional footballers. Further research is urgently needed to better understand the influence of the menstrual cycle on injury risk and to develop interventions to mitigate risk.
