This study compared basketball training and match demands between player roles (starters, in-rotation bench players, out-rotation bench players) and between competition levels (semi-professional, professional). Thirty-seven players from one professional women’s team, one semi-professional women’s team, and one semi-professional men’s team wore accelerometers during training and matches throughout a competitive season. All teams were used for player role comparisons and the women’s teams were used to compare competition levels. Match and training session average intensity and volume, and durations of relative exercise intensities (inactive, light, moderate-vigorous, maximal, supramaximal) were calculated. Compared to out-rotation bench players, starters experienced twice the average match intensity and volume, spent 50% less match time being inactive, and spent 1.7–4.2× more match time in all other activity categories (p < 0.01). Compared to in-rotation bench players, starters experienced 1.2× greater average match intensity and volume, spent 17% less match time being inactive, and spent 1.4–1.5× more match time performing moderate-vigorous and maximal activity (p < 0.01). No differences in match demands were found between women’s competition levels, however the professional team experienced double the cumulative weekly training volume of the semi-professional team and spent 1.6–2.1× more cumulative weekly time in all activity categories (p < 0.01). To improve performance and reduce injury risk, players should prepare for the greatest match demands they could encounter during a season while considering potential changes to their role. Additionally, players might need their training volume managed when transitioning from a semi-professional to a professional season to reduce the injury risk from sharp increases in training demands.

篮球运动中球员角色和比赛水平对球员需求的影响


本研究比较了球员角色（先发球员、轮换替补球员、轮换替补球员）和比赛级别（半职业、职业）之间的篮球训练和比赛要求。来自一支职业女子队、一支半职业女子队和一支半职业男子队的 37 名球员在整个赛季的训练和比赛中佩戴了加速度计。所有球队用于球员角色比较，女子队用于比较比赛水平。计算比赛和训练的平均强度和训练量，以及相对运动强度（不活动、轻度、中等强度、最大、超最大）的持续时间。与轮换替补球员相比，首发球员的平均比赛强度和比赛量是其两倍，不活动的比赛时间减少了 50%，并且在所有其他活动类别中花费的比赛时间多了 1.7–4.2 倍 ( p < 0.01)。与轮换替补球员相比，先发球员的平均比赛强度和比赛量增加了 1.2 倍，不活动的比赛时间减少了 17%，进行中等强度和最大活动的比赛时间增加了 1.4–1.5 倍（ p < 0.01）。女子比赛级别之间的比赛要求没有差异，但职业队每周累计训练量是半职业队的两倍，并且在所有活动类别中每周累计时间多出 1.6–2.1 倍（ p < 0.01）。为了提高表现并降低受伤风险，球员应该为赛季中可能遇到的最大比赛要求做好准备，同时考虑自己角色的潜在变化。 此外，球员在从半职业赛季过渡到职业赛季时可能需要管理训练量，以减少训练需求急剧增加带来的受伤风险。
