Abstract

PURPOSE

To examine potential differences in internal and external workload variables between playing positions and between training drills and games within an elite netball team during training and competition.

METHODS

Nine elite female netballers were monitored during 15 games and all training sessions over 28 weeks. Workload variables assessed were relative PlayerLoad (PL per minute), accelerations, decelerations, jumps, changes of direction, high-intensity events, medium-intensity events, low-intensity events, PL in a forward direction, PL in a sideways direction, PL in a vertical direction, and summated heart-rate zones using heart-rate monitors and inertial measurement units.

RESULTS

Conditioning and match play during training were the only drills that matched or exceeded game workloads. Workloads during small-sided games were lower than game workloads for all variables. In games, goalkeeper, goal attack, and goal shooter had a greater frequency of jumps compared with other positions. Midcourt positions had a greater frequency of low-intensity events in a game.

CONCLUSIONS

Workloads during small-sided games were lower than game workloads across all external and internal variables; therefore, netball staff should modify these small-sided games if they wish them to develop game-based qualities. Specific game workload variables indicate that there are differences within some positional groups; coaches need to be aware that positional groupings may fail to account for differences in workload between individual playing positions.

摘要

目的

研究精英女子篮球队在训练和比赛期间,不同比赛位置和不同训练练习之间的内部和外部工作负荷变量的潜在差异。

方法

对 9 名精英女子无挡板篮球运动员在 28 周内的 15 场比赛和所有训练课程进行了监测。评估的工作负荷变量包括相对球员负荷(每分钟的 PL)、加速度、减速度、跳跃、变向、高强度事件、中强度事件、低强度事件、向前方向的 PL、侧向方向的 PL、垂直方向的 PL 以及使用心率监测器和惯性测量单元的总和心率区。

结果

训练中的体能训练和比赛是唯一与比赛工作量匹配或超过比赛工作量的练习。所有变量的小场比赛的工作量都低于比赛的工作量。在比赛中,守门员、进攻队员和射门队员的跳跃频率比其他位置更高。中场位置在比赛中低强度事件的频率更高。

结论

所有外部和内部变量的小场比赛的工作量都低于比赛的工作量;因此,如果希望小场比赛能够发展基于比赛的素质,那么无挡板篮球工作人员应该对这些小场比赛进行修改。特定的比赛工作负荷变量表明,在某些位置组内存在差异;教练需要意识到,位置分组可能无法解释各个比赛位置之间的工作量差异。
