Artistic roller skating is a sport that involves high physical demands, particularly in the free skating discipline, where jumps are critical. Managing training loads is essential for optimizing performance and preventing injuries.
To investigate the internal and external training loads of female artistic roller skating athletes and to analyze the relationships between these loads components.
Cohort study.
Level 3.
A total of 15 female artistic roller skating athletes were monitored over a 4-week mesocycle leading up to the National Championship. Internal training load (ITL) was measured using the session rating of perceived exertion (sRPE), whereas external training load (ETL) was assessed with an inertial measurement unit capturing jumps and energy. Repeated measures analysis of variance (RMANOVA) and correlation analysis were conducted.
The RMANOVA revealed significant differences in monotony and strain of ITL, as well as in the monotony of jumps and energy. Significant correlations were found between ITL and ETL metrics, with higher sRPE and daily ITL associated with increased jumps and energy.
The findings highlight the interrelationships between internal and external load metrics, with higher perceived exertion and daily training loads associated with increased external workload, particularly in jump frequency and energy. In addition, training monotony and strain fluctuated across microcycles, with notable increases observed as the competition approached. These results emphasize the importance of systematically monitoring both internal and external training loads, including monotony and strain, to better understand workload dynamics and guide training adjustments.
The findings provide practical insights for coaches on how to balance training intensity and volume to enhance performance and prevent overtraining and injuries.
花样轮滑是一项对体能要求很高的运动，尤其是在自由滑项目中，跳跃动作至关重要。管理训练负荷对于优化运动表现和预防受伤至关重要。
调查女子花样轮滑运动员的内部和外部训练负荷，并分析这些负荷组成部分之间的关系。
队列研究。
3级。
在全国锦标赛前为期4周的中周期内，对15名女子花样轮滑运动员进行了监测。内部训练负荷（ITL）采用训练感知用力程度（sRPE）进行测量，而外部训练负荷（ETL）则通过惯性测量单元捕捉跳跃动作和能量来评估。进行了重复测量方差分析（RMANOVA）和相关性分析。
RMANOVA显示，ITL的单调性和应变以及跳跃动作和能量的单调性存在显著差异。发现ITL和ETL指标之间存在显著相关性，较高的sRPE和每日ITL与跳跃动作和能量的增加相关。
研究结果突出了内部和外部负荷指标之间的相互关系，较高的感知用力程度和每日训练负荷与增加的外部工作量相关，尤其是在跳跃频率和能量方面。此外，训练的单调性和应变在各个微周期中有所波动，在比赛临近时观察到显著增加。这些结果强调了系统监测内部和外部训练负荷（包括单调性和应变）的重要性，以便更好地了解工作量动态并指导训练调整。
研究结果为教练提供了关于如何平衡训练强度和训练量以提高运动表现、预防过度训练和受伤的实用见解。
