Throwing velocity is one of the most important factors for scoring goals in handball. This study aimed to identify the type of throw and procedure for selecting the final test outcome that provide throwing velocity with the greatest reliability. Fifteen experienced handball players and 33 non-experienced participants were tested in two sessions. Each session consisted of 4 trials of 3 different throwing tests (unspecific, 7-meters, and 3-steps). The maximum value of 4 trials, average value of 4 trials, and average value of the 3 best trials were considered. Throwing velocity was highly reliable (coefficient of variation [CV]≤3.3%, intraclass correlation coefficient≥0.89) with the exception of the unspecific throw for the non-experienced group (CV≥5.9%, intraclass correlation coefficient≤0.56). The 3-steps throw (CV=1.7%) was more reliable than the 7-meters throw (CV=2.1%) (CV=1.19) and unspecific throw (CV = 3.8%) (CV=2.18), the 3 procedures provided a comparable reliability (CV range=2.4-2.6%; CV≤1.07), and the experienced group (CV=1.0%) presented a higher reliability than the non-experienced group (CV=4.0%) (CV=3.83). These results support the 3-steps throw to maximise the reliability of throwing velocity performance.
投掷速度是手球比赛中得分的最重要因素之一。本研究旨在确定投掷方式和最终测试结果选择方法，以提供最大可靠性的投掷速度。15 名经验丰富的手球运动员和 33 名非经验参与者在两次会议中进行了测试。每次会议包括 4 次 3 种不同投掷测试（非特定、7 米和 3 步）的试验。考虑了 4 次试验的最大值、4 次试验的平均值和 3 次最佳试验的平均值。除了非经验组的非特定投掷（CV≥5.9%，组内相关系数≤0.56）外，投掷速度具有高度可靠性（变异系数 [CV]≤3.3%，组内相关系数≥0.89）。3 步投掷（CV=1.7%）比 7 米投掷（CV=2.1%）（CV=1.19）和非特定投掷（CV=3.8%）（CV=2.18）更可靠，3 种程序提供了可比的可靠性（CV 范围=2.4-2.6%；CV≤1.07），经验组（CV=1.0%）的可靠性高于非经验组（CV=4.0%）（CV=3.83）。这些结果支持采用 3 步投掷以最大限度地提高投掷速度表现的可靠性。
