The objective of the study was to describe the movement demands and running intensities of semi-professional rugby league players during a rugby league 9's (RL9's) tournament. Six semi-professional rugby league players competed in a RL9's tournament over a two-day period comprising of six games. Movement demands and running intensities were recorded using Global Positioning System (GPS) devices providing data on distance and speeds. Data is presented as mean (95% Confidence Intervals) with changes (≥ 75%) likely to exceed the smallest worthwhile change (0.2) considered practically important. Outside backs performed significantly (p < 0.05) more relative VHSR (3.9 m [3.5-4.3] vs 2.4 m [2.1-2.8]) absolute (97.7 m [81.3-114.1] vs 22.6m [15.8-29.3]) and relative (5.0 m·min [4.2-5.9] vs 1.2 m·min [0.8-1.6]) sprint distance than the forwards. Outside backs also performed significantly (p < 0.05) more absolute (97.7 m [81.3-114.1] vs 43.9 m [27.2-60.7]) and relative (5.0 m·min [4.2-5.9] vs 2.3 m·min [1.4-3.2]) sprint distance than the adjustables. Moderate (0.6 - 1.2) to very large (> 2.0) decreases in performance variables were observed over the two days. The biggest magnitude of change over the two days was seen with very large decreases in relative HSR (- 2.10) and sprint (- 2.14) distance. Between playing groups, the outside backs had the biggest decrease in running intensity with a very large (- 2.32) significant (p < 0.05) decrease in VHSR on day 2 (3.3 m·min [2.5 - 4.1]) compared to day 1 (4.9 m·min [4.4 - 5.4]). Running intensities are decreased during an intensified RL9's tournament in semi-professional rugby league players. The observed decreases in running performances between playing groups are in agreement with previous research and may support the use of individualized player monitoring and recovery management during a RL9's tournament-style competition.
本研究的目的是描述半职业橄榄球联盟球员在九人制橄榄球（RL9's）锦标赛期间的运动需求和跑步强度。六名半职业橄榄球联盟球员参加了为期两天的RL9's锦标赛，共进行六场比赛。使用全球定位系统（GPS）设备记录运动需求和跑步强度，该设备可提供距离和速度数据。数据以平均值（95%置信区间）呈现，变化（≥75%）可能超过被认为具有实际重要性的最小有价值变化（0.2）。外线球员在相对高速奔跑距离（3.9米[3.5 - 4.3]对2.4米[2.1 - 2.8]）、绝对高速奔跑距离（97.7米[81.3 - 114.1]对22.6米[15.8 - 29.3]）和相对冲刺距离（5.0米·分钟[4.2 - 5.9]对1.2米·分钟[0.8 - 1.6]）方面的表现明显（p < 0.05）高于前锋。外线球员在绝对冲刺距离（97.7米[81.3 - 114.1]对43.9米[27.2 - 60.7]）和相对冲刺距离（5.0米·分钟[4.2 - 5.9]对2.3米·分钟[1.4 - 3.2]）方面的表现也明显（p < 0.05）高于可调整位置球员。在两天内观察到表现变量出现中度（0.6 - 1.2）到非常大（> 2.0）的下降。两天内变化幅度最大的是相对高速奔跑距离（- 2.10）和冲刺距离（- 2.14）的大幅下降。在不同比赛位置组中，外线球员的跑步强度下降最大，与第1天（4.9米·分钟[4.4 - 5.4]）相比，第2天的高速奔跑距离大幅下降（- 2.32），显著（p < 0.05）降至3.3米·分钟[2.5 - 4.1]。在半职业橄榄球联盟球员参加的高强度RL9's锦标赛期间，跑步强度会降低。观察到的不同比赛位置组之间跑步表现的下降与先前的研究一致，这可能支持在RL9's锦标赛式比赛中使用个性化的球员监测和恢复管理。
