摘要

速度强度性能在很大程度上取决于最大强度。然而,各种强度测试方法确定了绝对强度和相对强度与短跑和跳跃成绩之间不一致的关系。本研究的目的是计算青少年足球运动员(n= 63, 17.9±2.1岁)在平行深蹲和不同起跳(深蹲起跳和反动作起跳)和短跑(5米、10米、20米和30米)中单次重复最大值(1RM)和1RM与体重(1RM/BM)的单尾相关系数。相对强度与跳跃表现的相关性(r= 0.52 ~ 0.58)显著高于绝对强度(r= 0.16 ~ 0.26, z= -1.81 ~ -1.90, p= 0.029 ~ 0.035)。相对强度测量值与短跑成绩之间的r值(r= -0.32 ~ -0.42)与绝对强度测量值与短跑成绩之间的相关性(r= -0.19 ~ -0.3, z= 0.349 ~ 1.17, p= 0.121 ~ 0.363)无统计学差异。这项研究的结果支持了先前文献的发现,即青少年足球运动员的最大力量水平越高,速度力量表现越好,速度更快,力量更大的运动员能够产生更大的力量来对抗自己的体重。数据表明,相对于身体质量表达的力量可能被认为是一般速度力量表现的优越预测指标。

Absolute and relative maximum strength measures show differences in their correlations with sprint and jump performances in trained youth soccer players
Speed strength performances are heavily dependent on maximum strength. However, various strength testing methods determined inconsistent relationships between absolute and relative strength and sprint and jump performances. The aim of the study was to calculate the one tailed correlation coefficients between both the One-Repetition Maximum (1RM) and 1RM in relation to body mass (1RM/BM) in parallel squats and different jump (squat jump and countermovement jump) and sprint performances (5-, 10-, 20-, and 30-m) in youth soccer players (n= 63, 17.9±2.1 years old). Relative strength showed significantly larger correlations with jump performances (r= 0.52 to 0.58) than absolute strength (r= 0.16 to 0.26, z= -1.81 to -1.90, p= 0.029 to 0.035). However, the r values between relative strength measures and sprint performances (r= -0.32 to -0.42) were of non-statistical difference to the correlations of absolute strength measurements with sprint performances (r= -0.19 to -0.3, z= 0.349 to 1.17, p= 0.121 to 0.363). The results of this study support findings in previous literature of enhanced speed strength performances by higher levels of maximal strength in youth soccer players, with faster and more powerful athletes being able to generate larger forces against their own body weight. The data suggests that strength expressed relative to body mass might be considered as a superior predictor of speed strength performance in general.
