Isokinetic testing has been routinely used to assess the capacities of individual muscle groups. In this study we aimed to evaluate the sensitivity of the force-point (F-v) relationship assessed through the two-point method to discriminate between antagonist muscle groups and males with different physical activity levels.
The concentric force output of the knee, hip, elbow, and shoulder flexors and extensors of 27 active and 13 non-active men was recorded at 60 and 180°/s to determine the F-v relationship parameters (maximum force [], maximum velocity [], and maximum power [P]).
and P were higher for knee extensors (effect size [ES] = 1.97 and 0.57, respectively), hip extensors (ES = 2.52 and 0.77, respectively), and shoulder flexors (ES = 1.67 and 0.83, respectively) compared to their antagonist muscles, while was higher for knee flexors compared to knee extensors (ES = 0.59). Active males revealed higher for knee extensors (ES = 0.72) and knee flexors (ES = 0.83) and higher P for knee flexors (ES = 0.70), elbow extensors (ES = 0.83) and shoulder extensors (ES = 0.36).
The sensitivity of the two-point method for testing the maximal mechanical capacities was high for the knee, moderate for the hip and shoulder, and low for the elbow joint.
等速测试已被常规用于评估个体肌肉群的能力。本研究旨在评估两点法评估的力点（F-v）关系的敏感性，以区分拮抗肌群和不同身体活动水平的男性。
记录 27 名活跃男性和 13 名非活跃男性的膝关节、髋关节、肘关节和肩关节屈伸肌的向心力量输出，以确定 F-v 关系参数（最大力量 []、最大速度 [] 和最大功率 [P]）。
与拮抗肌相比，膝关节伸肌（效应大小 [ES] = 1.97 和 0.57）、髋关节伸肌（ES = 2.52 和 0.77）和肩关节屈肌（ES = 1.67 和 0.83）的 和 P 更高，而与膝关节伸肌相比，膝关节屈肌的 更高（ES = 0.59）。活跃男性的膝关节伸肌（ES = 0.72）和膝关节屈肌（ES = 0.83）的 更高，膝关节屈肌（ES = 0.70）、肘关节伸肌（ES = 0.83）和肩关节伸肌（ES = 0.36）的 P 更高。
两点法测试最大机械能力的敏感性对于膝关节较高，对于髋关节和肩部为中等，对于肘关节较低。
