In handball, injury occurs more frequently during actual games than during handball practice. However, mechanical loading during actual games is unknown.
The purpose of this study was to describe body impact characteristics during handball games using accelerometers, and to investigate sex differences in these characteristics.
Comparative observational study.
Acceleration data were measured during practice games in 24 high school handball players (12 males, 12 females). The acceleration was set to 1 gravitational acceleration (G) when each axis direction was aligned with the direction of gravity during data collection. High-impact movements with a resultant acceleration of ≥ 6G were extracted, and video images was used to identify movements and plays during which the high-impact movements occurred. The number of cases, percentage, frequency (cases/min ･ person), and 95% confidence interval of the frequency were calculated for the movement classification, play classification, and movement classification × play classification. The peak acceleration values of resultant accelerations of ≥ 6G were also obtained.
The frequencies of resultant acceleration ≥ 6G were 5.3 cases/min ･ person for males and 4.7 cases/min ･ person for females. Deceleration and sprinting were the most frequent motion categories in both sexes. High-impact movements were more frequent in fast attack-related play in males and attack-to-defense transitions in females.
High-impact movements are more frequent in plays related to fast attacks in males and when switching from attack to defense in females. High-impact movements are more likely to occur during the switch from attack to defense in females.
在手球运动中，实际比赛期间的受伤频率高于手球训练期间。然而，实际比赛中的机械负荷情况尚不清楚。
本研究的目的是使用加速度计描述手球比赛期间的身体撞击特征，并调查这些特征中的性别差异。
比较观察性研究。
对24名高中手球运动员（12名男性，12名女性）在练习赛期间测量加速度数据。在数据收集期间，当每个轴方向与重力方向对齐时，加速度设置为1重力加速度（G）。提取合成加速度≥6G的高冲击力动作，并使用视频图像识别高冲击力动作发生时的动作和比赛情况。计算动作分类、比赛分类以及动作分类×比赛分类的病例数、百分比、频率（病例数/分钟·人）和频率的95%置信区间。还获得了合成加速度≥6G的峰值加速度值。
合成加速度≥6G的频率，男性为5.3例/分钟·人，女性为4.7例/分钟·人。减速和冲刺是两性中最常见的动作类别。高冲击力动作在男性与快攻相关的比赛中以及女性从进攻到防守的转换中更为频繁。
高冲击力动作在男性与快攻相关的比赛中以及女性从进攻转换为防守时更为频繁。高冲击力动作在女性从进攻转换为防守期间更有可能发生。
