摘要

最大肌力檢測對於訓練計畫的安排和疲勞程度的評估十分重要。傳統的檢測流程費時又費力，因而出現許多替代方法和預測公式。本篇研究的目的為探討速度參數在臥推運動中的量測以及速度參數應用於預測臥推最大肌力。隨著科技的進步，線性位置傳感器能夠有效地量測臥推運動時槓鈴的移動速度。臥推的運動速度可以分為平均向心速度、平均推進速度以及峰值速度。速度參數相關的研究顯示臥推速度和負荷之間呈現高度的相關性，因此只要能建立速度與負荷之間的關係式便能預測其最大肌力。目前的研究顯示，平均向心速度和平均推進速度都能有效地預測臥推最大肌力，然而何者的預測精準度較高則尚無一致的結論。未來若能將速度參數預測最大肌力相關的研究應用於不同自由重量動作，則能夠提供教練更多關於速度訓練量化和精準評估疲勞狀態的資訊。

The maximum muscle strength assessment is very important for the arrangement of the training program and the management of fatigue. Traditional assessment methods are often time-consuming and exhaustive. Therefore, many alternative methods and prediction equations appears. The purpose of this review is to provide an overview of the velocity measurement in bench press exercise and the application of velocity parameters to predict the maximum muscle strength of the bench press exercise. With the advancement of kinematic technology, linear position transducer has the ability to measure barbell velocity of bench press exercise. Velocity of bench press exercise can be measured in mean concentric velocity, mean propulsive velocity and peak velocity. Researches on bench press velocity parameters show a high correlation between velocity and load. As long as establishing the relationship between velocity and load, the maximum muscle strength can be predicted. Current researches show that mean concentric velocity and mean propulsive velocity can effectively predict the maximum strength of the bench press exercise. However, which one has a higher prediction accuracy remains questionable. In the future, if researches relate to velocity parameter prediction of maximum muscle strength can be applied to different free weight exercises, it can provide coaches with more information about velocity training quantification and accurate assessment of fatigue status.
