COMPARISON BETWEEN BENCH PRESS THROW AND BALLISTIC PUSH-UP TESTS TO ASSESS UPPER-BODY POWER IN TRAINED INDIVIDUALS

The purpose of this study was to validate the ballistic push-up (BPU) test performed with hands on a force plate as a method to measure upper-body power. Twenty-eight experienced resistancetrained men (age = 25.4 +/- 5.2 years; body mass = 78.5 +/- 9.0 kg; body height = 179.6 +/- 7.8 cm) performed, 2 days apart, a bench press 1 repetition maximum (1 RM) test and upper-body power tests. Mean power (MP) and peak power (PP) were assessed using the bench press throw (BT) test and the BPU test performed in randomized order. The area under the force/power curve (AUC) obtained at BT was also calculated. Power expressed at BPU was estimated using a timebased prediction equation. Mean force and the participant's body weight were used to predict the bench press 1 RM. Pearson product-moment correlations were used to examine relationships between the power assessment methods and between the predicted 1 RM bench and the actual value. Large correlations (0.79; p < 0.001) were found between AUC and MP expressed at BPU. Large correlations were also detected between MP and PP expressed at BT and BPU (0.75; p < 0.001 and 0.74; p < 0.001, respectively). Very large correlations (0.87; p < 0.001) were found between the 1RM bench and the 1 RM predicted by the BPU. Results of this study indicate that BPU represents a valid and reliable method to estimate the upper-body power in resistance-trained individuals.
