Eight, eumenorrheic, collegiate soccer players (19.5 ± 0.75 years, 1.62 ± 4.90 cm, 61.12 ± 7.6 kg mean ± SD) completed eccentric knee flexor and concentric knee extensor trials at 60 and 240°·s^-1 during the follicular, ovulation and luteal phases of their MC. Peak torque and corresponding angle of peak torque were maintained across all phases of the MC, irrespective of testing modality and speed (<i>p</i> ≥ 0.149). Strength ratios defined using peak torque were also not sensitive to MC phase (<i>p</i> ≥ 0.933). However, Functional Range in eccentric knee flexion was significantly lower during the follicular phase (<i>p</i> = 0.017), at both testing speeds. This supports epidemiological observations but highlights the importance of analysing isokinetic data beyond the peak of the strength curve. Interpretation of isokinetic data should therefore focus on points of \"weakness\" as opposed to maximum strength, whilst (p)rehabilitative strategies should consider strength through range of motion, and at different speeds. Eccentric hamstring strength was observed to decrease significantly at the higher speed, contrary to observations in elite male players, and potentially reflecting a differential training adaptation.</p>","PeriodicalId":20958,"journal":{"name":"Research in Sports Medicine","volume":" ","pages":"87-96"},"PeriodicalIF":1.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142522834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was conducted with 250 female cricket players aged 14-28 who had experienced injuries. Participants completed a structured questionnaire that gathered information on injury type, frequency, recurrence, treatment methods, and post-injury performance. Logistic regression analysis was employed to assess the relationship between injury risk and key variables, including playing position (batter, bowler, or fielder), weekly workload (hours spent in training/competition), and injury context (occurring during matches or practice). Descriptive statistics were used to summarize injury patterns and recovery outcomes, while odds ratios (OR) with 95% confidence intervals (CI) were calculated to identify significant predictors of injury risk. Of the participants, 75.2% experienced new injuries, while 24.8% reported chronic injuries. The most common injury sites were the knee/leg (24%) and shoulder (20%). Recurrence was high, with 56% experiencing 5-6 injury recurrences, and 68% reported multiple injuries over their careers. Physiotherapy was the primary treatment, used by 52% of participants, and 76% of players returned to competition post-injury. However, only 8% regained their pre-injury performance levels.

The findings highlight the prevalence of injuries in female cricket, particularly in bowlers and those with high workloads.
