Post-match assessment of creatine kinase (CK) activity and delayed-onset muscle soreness (DOMS) are common markers of exercise-induced muscle damage and recovery status in soccer players. These responses have not been examined in youth female players. This study examined the effect of competitive match play on CK activity and DOMS in elite youth players. Thirty-four elite female players, divided into three chronological age groups (U13, n=11; U15, n=10; U17 n=12). Players completed baseline testing for CK and DOMS that was repeated immediately (for DOMS), 80, 128 and 168 h post-competitive match play for CK. Significant time effects were reported for CK (P=0.006) and DOMS (P<0.01). Significant differences between baseline and 168 h post-match were reported for CK (P<0.01), with significant group differences between the U13 and U17 groups for CK (P<0.01). All parameters returned to baseline in U17s at 168 h, but increased CK was evident for U13s and U15s at 168 h. In conclusion, seven days may be insufficient for biochemical recovery in youth female athletes. Therefore, monitoring strategies to assess muscle damage between training and match play should be considered to track recovery and potentially reduce muscular injury risk.
赛后对肌酸激酶（CK）活性和延迟性肌肉酸痛（DOMS）的评估是足球运动员运动引起的肌肉损伤和恢复状况的常见指标。这些反应尚未在青年女性运动员中进行研究。本研究调查了竞技比赛对精英青年运动员CK活性和DOMS的影响。34名精英女性运动员分为三个年龄组（U13组，n = 11；U15组，n = 10；U17组，n = 12）。运动员完成了CK和DOMS的基线测试，CK测试在赛后立即进行，之后在80、128和168小时重复测试，DOMS测试则在赛后立即重复测试。CK（P = 0.006）和DOMS（P < 0.01）均报告有显著的时间效应。CK在基线和赛后168小时之间报告有显著差异（P < 0.01），U13组和U17组之间的CK有显著组间差异（P < 0.01）。168小时时，U17组的所有参数均恢复到基线，但U13组和U15组在168小时时CK仍明显升高。总之，七天时间可能不足以让青年女性运动员实现生化恢复。因此，应考虑采用监测策略来评估训练和比赛之间的肌肉损伤情况，以跟踪恢复情况并潜在降低肌肉损伤风险。
