Bench press, counter movement squat, maximal power output, optimal load, regression model

Hodnoty pro maximální dynamickou The purpose of this study was to create a regression model of the relationship between load and muscle power output and to determine an optimal load for maximal power output during counter movement squat and bench press. Values for the maximum dynamic strength and load for each lift were used to develop a cubic regression model in which the ratio of power was predicted from the ratio of the load for each type of lift. By optimizing the cubic regression model, we predicted the optimal rates of load for maximum muscle power. For bench press and counter movement squat the mean values of optimal rates of load for maximum muscle output range between 50-70% maximum dynamic strength. We found out that optimal load in accelerating phase of the upward movement of the specific exercises appears to be more important than over the full range of the movement. This model allows for specific determination of the optimal load to elicit a pre-determined power output.
