Trial matches are frequently used for team preparation in rugby league competitions, making it essential to understand the demands experienced to assess their specificity to actual competition. Consequently, this study aimed to compare the activity demands between pre-season trial matches and early in-season rugby league matches. Following a repeated-measures observational design, 39 semi-professional, male rugby league players from two clubs were monitored using microsensors during two trial matches and the first two in-season matches across two consecutive seasons. Total distance, average speed, peak speed, absolute and relative high-speed running (HSR; > 18 km · h) and low-speed running (LSR; < 18 km · h) distance, as well as absolute and relative impacts, accelerations (total and high-intensity > 3 m · s), and decelerations (total and high-intensity < -3 m · s) were measured. Linear mixed models and Cohen's d effect sizes were used to compare variables between match types. Playing duration was greater for in-season matches ( < 0.001, = 0.64). Likewise, higher ( < 0.001, = 0.45-0.70) activity volumes were evident during in-season matches indicated via total distance, HSR distance, LSR distance, total accelerations, high-intensity accelerations, total decelerations, and high-intensity decelerations. Regarding activity intensities, a higher average speed ( = 0.008, = 0.31) and relative LSR distance ( = 0.005, = 0.31) only were encountered during in-season matches. Despite players completing less volume, the average activity intensities and impact demands were mostly similar between trial and early in-season matches. These findings indicate trial matches might impose suitable activity stimuli to assist players in preparing for early in-season activity intensities.
在橄榄球联盟比赛中,季前热身赛常被用于球队准备,因此了解其比赛要求对于评估其与实际比赛的契合度至关重要。因此,本研究旨在比较季前热身赛和赛季初期橄榄球联盟比赛之间的活动需求。采用重复测量观察设计,在两个连续赛季的两场热身赛和前两场赛季内比赛期间,使用微传感器对来自两个俱乐部的39名半职业男性橄榄球联盟球员进行监测。测量了总距离、平均速度、峰值速度、绝对和相对高速奔跑(HSR;>18 km·h)以及低速奔跑(LSR;<18 km·h)距离,以及绝对和相对冲击力、加速度(总和高强度>3 m·s)和减速度(总和高强度<-3 m·s)。使用线性混合模型和科恩d效应量来比较不同比赛类型之间的变量。赛季内比赛的比赛时长更长(<0.001,=0.64)。同样,通过总距离、HSR距离、LSR距离、总加速度、高强度加速度、总减速度和高强度减速度表明,赛季内比赛期间的活动量更高(<0.001,=0.45 - 0.70)。关于活动强度,仅在赛季内比赛中遇到更高的平均速度(=0.008,=0.31)和相对LSR距离(=0.005,=0.31)。尽管球员完成的活动量较少,但热身赛和赛季初期比赛之间的平均活动强度和冲击需求大多相似。这些发现表明,热身赛可能会施加合适的活动刺激,以帮助球员为赛季初期的活动强度做好准备。
