Abstract

BACKGROUND: We aimed to determine the relationship between bench press (BP) and bench throw (BT), with respect to the maximum mechanical power output (Pmax) and load at Pmax (Pmax load). METHODS: Thirteen male collegiate football players participated in this study. During the first testing session, we determined each subject's one-repetition maximum (1RM) bench press strength using a Smith machine. During the second testing session, ballistic BP and BT exercises were performed using the Smith machine set at different loads ranging from 30.0 kg to 90% of 1RM. The barbell positions were measured using a linear position transducer, and barbell velocity, force, and power output during ballistic BP and BT were calculated using a dynamic equation. We determined Pmax and Pmax load by fitting second-order polynomials to the data. RESUlTS: The Pmax of BP was significantly lower than the Pmax of BT. However, the Pmax load in BP was significantly greater than that in BT. The Pmax of BT was significantly correlated with the Pmax of BP; conversely, the Pmax load in BT was not significantly correlated with the Pmax load in BP. CONClUSIONS: Our results suggest that the Pmax load is overestimated when using the BP test compared with BT. Furthermore, it is difficult to predict the Pmax load in BT using the Pmax load in BP.
