The purpose of the present study was to analyze the association between isokinetic strength and field-based muscular fitness tests in youth.
One hundred twenty-six adolescents (14.4±1.7 y) participated in the study. Upper and lower body isokinetic strength were measured at preset angular velocities of 90 º/s and 60 º/s, respectively. Muscular fitness was also assessed by means of field-based tests: handgrip strength, bent and extended arm hang tests, standing long jump, squat jump, countermovement jump and Abalakov jump. Height, weight and skinfold thickness were used to estimate body composition.
All field-based tests were significantly associated with isokinetic peak torque and power (P<0.001 in all cases). Handgrip strength and standing long jump showed the highest associations with the isokinetic parameters (0.61≤r≤0.87; 0.39≤R2≤0.76). Weight-bearing field tests increased on average 20 % their association (R2) with isokinetic parameters when standardized by individual's body weight (test score × weight), while the average increase was 16 % when standardized by fat-free mass (test score × fat-free mass).
Handgrip strength and standing long jump tests seem to be the most valid field-based muscular fitness tests when compared to isokinetic strength. These tests can be useful to assess muscular fitness in young people when laboratory methods are not feasible.
本研究旨在分析青少年等速肌力与基于场地的肌肉适能测试之间的关联。
126名青少年（14.4±1.7岁）参与了本研究。分别在90°/s和60°/s的预设角速度下测量上下肢等速肌力。还通过基于场地的测试评估肌肉适能：握力、屈臂悬垂和伸臂悬垂测试、立定跳远、深蹲跳、反向纵跳和阿巴拉科夫跳。身高、体重和皮褶厚度用于估计身体成分。
所有基于场地的测试均与等速峰值扭矩和功率显著相关（所有情况下P<0.001）。握力和立定跳远与等速参数的相关性最高（0.61≤r≤0.87；0.39≤R2≤0.76）。当按个体体重（测试分数×体重）进行标准化时，负重场地测试与等速参数的关联（R2）平均增加20%，而按去脂体重（测试分数×去脂体重）进行标准化时，平均增加16%。
与等速肌力相比，握力和立定跳远测试似乎是最有效的基于场地的肌肉适能测试。当实验室方法不可行时，这些测试可用于评估年轻人的肌肉适能。
