ABSTRACT

An a-posteriori multicentre reliability study was conducted to compare the reliability and magnitude of the maximum power (P_max) and optimal velocity (V_opt) between the force-power-velocity relationships during the leg cycle-ergometer and bench press throw exercises. The force-power-velocity relationships were determined in two separate sessions considering the values of force, velocity, and power collected under multiple loads. The force–velocity relationship was also determined from the force and velocity values collected under only the two most distant loads. Reliability of all regression models was high for P_max and V_opt during the leg cycle-ergometer (CV_range: 1.73–2.98%) and for P_max during the bench press throw (CV_range: 4.47–4.73%), while the reliability was acceptable for V_opt during the bench press throw (CV_range: 6.52–7.34%). Significant differences between the force-power-velocity relationships were observed for both P_max and V_opt (P < .001). All regression models can be confidently used to determine P_max and V_opt, but these should not be used interchangeably.

摘要

进行了一项事后多中心可靠性研究，以比较腿部自行车测力计和卧推投掷练习期间力-功率-速度关系之间的最大功率 (P _max ) 和最佳速度 (V _opt )的可靠性和幅度。考虑在多个负载下收集的力、速度和功率值，力-功率-速度关系是在两个单独的会话中确定的。力-速度关系也由仅在两个最远载荷下收集的力和速度值确定。在腿部循环测力计（CV_范围：1.73–2.98%）和 P _max期间，所有回归模型的 P _max和 V _{opt 的}可靠性都很高在卧推投掷期间（CV_范围：4.47–4.73%），而在卧推投掷期间V _opt的可靠性是可以接受的（CV_范围：6.52–7.34%）。对于 P _max和 V _opt ( P < .001) ，观察到力-功率-速度关系之间的显着差异。所有回归模型都可以自信地用于确定 P _max和 V _opt，但这些模型不应互换使用。
