The aim of this study was to verify the impact of ethnicity on the maximal power-vertical jump relationship. Thirty-one healthy males, sixteen Caucasian (age: 26.3 ± 3.5 years; body height: 179.1 ± 5.5 cm; body mass: 78.1 ± 9.8 kg) and fifteen Afro-Caribbean (age: 24.4 ±2.6 years; body height: 178.9 ± 5.5 cm; body mass: 77.1 ± 10.3 kg) completed three sessions during which vertical jump height and maximal power of lower limbs were measured. The results showed that the values of vertical jump height and maximal power were higher for Afro-Caribbean participants (62.92 ± 6.7 cm and 14.70 ± 1.75 W∙kg-1) than for Caucasian ones (52.92 ± 4.4 cm and 12.75 ± 1.36 W∙kg-1). Moreover, very high reliability indices were obtained on vertical jump (e.g. 0.95 < ICC < 0.98) and maximal power performance (e.g. 0.75 < ICC < 0.97). However, multiple linear regression analysis showed that, for a given value of maximal power, the Afro-Caribbean participants jumped 8 cm higher than the Caucasians. Together, these results confirmed that ethnicity impacted the maximal power-vertical jump relationship over three sessions. In the current context of cultural diversity, the use of vertical jump performance as a predictor of muscular power should be considered with caution when dealing with populations of different ethnic origins.
本研究的目的是验证种族对最大力量与垂直纵跳关系的影响。31名健康男性，16名白种人（年龄：26.3±3.5岁；身高：179.1±5.5厘米；体重：78.1±9.8千克）和15名非裔加勒比人（年龄：24.4±2.6岁；身高：178.9±5.5厘米；体重：77.1±10.3千克）完成了三个阶段的测试，在此期间测量了垂直纵跳高度和下肢最大力量。结果显示，非裔加勒比参与者的垂直纵跳高度和最大力量值（62.92±6.7厘米和14.70±1.75瓦·千克-1）高于白种人参与者（52.92±4.4厘米和12.75±1.36瓦·千克-1）。此外，垂直纵跳（如0.95＜组内相关系数＜0.98）和最大力量表现（如0.75＜组内相关系数＜0.97）获得了非常高的可靠性指标。然而，多元线性回归分析表明，对于给定的最大力量值，非裔加勒比参与者比白种人高出8厘米。总之，这些结果证实了种族在三个阶段中对最大力量与垂直纵跳关系产生了影响。在当前文化多样性的背景下，在处理不同种族来源的人群时，应谨慎考虑将垂直纵跳表现用作肌肉力量的预测指标。
