Ten females performed 90 min of the Loughborough Intermittent Shuttle Test (LIST) on two occasions separated by 7 days. Water [3 mL/kg body mass (BM)] was provided every 15 min during exercise (FL); no fluid was given in the other trial (NF). Participants performed the Loughborough Soccer Passing Test (LSPT) before and every 15 min during the LIST. Core temperature (T(c) ) was measured throughout using ingestible temperature sensors. Heart rate (HR), blood lactate ([La(-) ]) and ratings of perceived exertion (RPE) were collected at regular intervals during exercise. Participants experienced greater BM loss in NF (2.2 ± 0.4%) than FL (1.0 ± 0.4%; P<0.001). Sprint performance deteriorated by 2.7% during exercise (P<0.001) but there was no difference between trials (P=0.294). No significant differences in LSPT performance were detected between trials (P=0.31). T(c) was higher during exercise in NF and was 38.6 ± 0.3 °C (NF) and 38.3 ± 0.3 °C (FL; P<0.01) after 90 min. HR (P<0.001), [La(-) ] (P<0.01) and RPE (P=0.009) were higher during exercise in NF. Ingesting water during a 90-min match simulation reduces the mild dehydration seen in female soccer players when no fluid is consumed. However, there was no effect of fluid ingestion on soccer passing skill or sprint performance.
十位女性在两次试验中进行了 90 分钟的拉夫堡间歇性穿梭测试（LIST），两次试验间隔 7 天。运动期间每 15 分钟提供 3 毫升/公斤体重（BM）的水（FL）；在另一次试验中不给水（NF）。参与者在进行 LIST 之前和 LIST 期间的每 15 分钟进行一次拉夫堡足球传球测试（LSPT）。核心温度（T(c)）在整个过程中使用可摄入的温度传感器进行测量。运动期间定期收集心率（HR）、血乳酸（[La(-) ]）和感知用力程度（RPE）。参与者在 NF 中经历了更大的 BM 损失（2.2±0.4%），而在 FL 中损失了 1.0±0.4%（P<0.001）。运动期间冲刺表现恶化了 2.7%（P<0.001），但两次试验之间没有差异（P=0.294）。两次试验之间 LSPT 表现没有显著差异（P=0.31）。NF 运动期间的 T(c)更高，运动 90 分钟后，NF 为 38.6±0.3°C，FL 为 38.3±0.3°C（P<0.01）。HR（P<0.001）、[La(-) ]（P<0.01）和 RPE（P=0.009）在 NF 运动期间更高。在 90 分钟的比赛模拟中摄入水分可减少女性足球运动员在不摄入水分时出现的轻度脱水。然而，摄入水分对足球传球技能或冲刺表现没有影响。
