球棒-球碰撞的物理方程与肌肉力量-速度关系的生理学相结合，以计算单个棒球运动员的理想球棒重量。这种耦合的结果表明，一些击球手使用的球棒对他们来说太重，而一些击球手使用的球棒太轻，但大多数有经验的击球手使用的球棒恰到好处。然而，理想的蝙蝠体重与身高、体重或年龄无关。几十年前对离体肌的力-速度关系的生理学研究表明，双曲线通常与数据拟合得最好。然而，对于目前的数据，双曲线只适合一类受试者：对于其他受试者，直线提供了最好的拟合性。我们假设这两类玩家使用不同的控制策略。
The equations of physics for bat-ball collisions were coupled to the physiology of the muscle force-velocity relationship to compute the ideal bat weight for individual baseball players. The results of this coupling suggest that some batters use bats that are too heavy for them, and some batters use bats that are too light, but most experienced batters use bats that are just right. However, ideal bat weight is not correlated with height, weight, or age. Decades of prior physiological research on force-velocity relationships of isolated muscle have shown that hyperbolic curves usually fit the data best. However, for the present data, the hyperbolic curves fit only one class of subjects best: for the others a straight line provides the best fit. We hypothesize that these two classes of players use different control strategies.
