In studies of physical performance comprising muscle strength and power, a vertical jump is a test method that frequently is used. It is important to have access to accurate measuring tools providing data with high reproducibility. Studies have shown that body composition also may play an important part in physical performance. The purpose of this study was to determine test-retest reliability for 3 different kinds of vertical jumps and to correlate jump height with body composition. Thirty-four normally trained subjects (women n = 17) between 18 and 25 years participated. Test-retest, on 3 kinds of vertical jumps, was performed with a median of 7 days between jumps. Methods used were a countermovement jump (CMJ) on a contact mat, with and without arm swing, and an Abalakow jump (AJ) using measuring tape, with arm swing. Body composition was assessed with the use of bioelectric impedance analysis. The results showed that high intraclass correlation coefficients (ICCs) were observed between testing occasions for all 3 vertical jumps (ICC between 0.48 and 0.88). The AJ in women presented the lowest ICC. Also the correlation between CMJ and AJ was high (rs = 0.88). Moderate-to-high correlations could be shown between body composition and CMJ in women (rs = -0.57-0.76). In conclusion, very high test-retest reliability for CMJ on a contact mat was found. For the AJ using a measuring tape, ICC were overall high, but a moderate nonsignificant ICC were found in women, indicating poor reproducibility. The data from the CMJ and AJ may be compared if approximately 25% of the AJ value is subtracted. In practice, this means that vertical jump tests have high reproducibility and can be used as measures of power development.
在包括肌肉力量和功率的身体性能研究中，垂直跳跃是一种经常使用的测试方法。获得能够提供具有高再现性数据的精确测量工具非常重要。研究表明，身体成分在身体性能中也可能起着重要作用。本研究的目的是确定三种不同垂直跳跃的重测信度，并将跳跃高度与身体成分相关联。34名年龄在18至25岁之间的正常训练受试者（女性n = 17）参与了研究。对三种垂直跳跃进行了重测，两次跳跃之间的中位数间隔为7天。使用的方法包括在接触垫上进行有或无摆臂的反向运动跳跃（CMJ），以及使用卷尺进行有摆臂的阿巴拉科夫跳跃（AJ）。使用生物电阻抗分析评估身体成分。结果表明，所有三种垂直跳跃在测试场合之间均观察到高组内相关系数（ICC）（ICC在0.48至0.88之间）。女性的AJ呈现出最低的ICC。此外，CMJ和AJ之间的相关性也很高（rs = 0.88）。女性的身体成分与CMJ之间可显示出中度至高度的相关性（rs = -0.57 - 0.76）。总之，发现接触垫上的CMJ具有非常高的重测信度。对于使用卷尺的AJ，ICC总体较高，但在女性中发现了中度无统计学意义的ICC，表明再现性较差。如果减去AJ值的约25%，则可以比较CMJ和AJ的数据。在实践中，这意味着垂直跳跃测试具有高再现性，可作为力量发展的测量指标。
