To describe the physiological and activity demands experienced by Australian female basketball players during competition.
A between-subjects (positional comparison) repeated measures (playing periods) observational experimental design was followed.
State-level basketball players (n=12; age: 22.0±3.7 yr; body mass: 72.9±14.2 kg; stature: 174.2±6.9 cm; body fat: 17.2±5.6%; estimated V˙O(2max):43.3±5.7 ml kg⁻¹ min⁻¹) volunteered to participate. Heart rate (HR) and blood lactate concentration ([BLa]) were collected across eight competitive matches. Overall and positional player activity demands were calculated across three matches using time-motion analysis methodology. Activity frequencies, total durations and total distances were determined for various activity categories.
Mean (±SD) HR responses of 162±3b min⁻¹ (82.4±1.3% HR(max)) and 136±6b min⁻¹ (68.6±3.1% HR(max)) were evident across live and total time during matches. A mean [BLa] of 3.7±1.4 mmol L⁻¹ was observed across competition. Player activity demands were unchanged across match periods, with 1752±186 movements performed and 5214±315 m travelled across total live match time. Furthermore, 39±3%, 52±2%, 5±1% and 4±1% of total live time was spent performing low-intensity, moderate-intensity, high-intensity and dribbling activity. Positional comparisons revealed backcourt players performed more ball dribbling (p<0.001) and less standing/walking (p<0.01) and running (p<0.05) than frontcourt players.
Together, these findings highlight the high intermittent demands and important contributions of both anaerobic and aerobic metabolic pathways during state-level female basketball competition.
描述澳大利亚女子篮球运动员在比赛中经历的生理和活动需求。
采用了受试者间（位置比较）重复测量（比赛时段）观察性实验设计。
有 12 名州级篮球运动员（年龄：22.0±3.7 岁；体重：72.9±14.2 公斤；身高：174.2±6.9 厘米；体脂：17.2±5.6%；估计最大摄氧量：43.3±5.7 ml·kg⁻¹·min⁻¹）自愿参加了这项研究。在八场比赛中收集了心率（HR）和血乳酸浓度（[BLa]）。使用时间-动作分析方法，在三场比赛中计算了总体和位置球员的活动需求。确定了各种活动类别的活动频率、总持续时间和总距离。
在比赛的总时间和实际时间中，平均（±SD）HR 反应分别为 162±3b min⁻¹（82.4±1.3% HR(max)）和 136±6b min⁻¹（68.6±3.1% HR(max)）。比赛中观察到平均 [BLa]为 3.7±1.4 mmol L⁻¹。在比赛期间，球员的活动需求没有变化，在总实际比赛时间内完成了 1752±186 次动作，行进了 5214±315 米。此外，总实际比赛时间的 39±3%、52±2%、5±1%和 4±1%分别用于低强度、中等强度、高强度和运球活动。位置比较显示，后场球员的运球次数更多（p<0.001），站立/行走（p<0.01）和跑动（p<0.05）次数更少。
这些发现共同强调了在州级女子篮球比赛中，间歇性需求高，无氧和有氧代谢途径都很重要。
