Effects of Postactivation Potentiation on Tennis Serve Velocity and Accuracy.

Abstract

To examine the postactivation potentiation effect on serve velocity and accuracy in young competition tennis players using complex training, and comparing different upper and lower body heavy-load resistance exercises (HLRE). Fifteen competition tennis players (9 boys and 6 girls; age 15.6 [1.5]y) performed 1 control session and 3 experimental sessions using HLRE in a crossover randomized design: (1)bench press, (2)half squat, (3)bench press plus half squat, and (4)control trial. HLRE were performed by accomplishing 3 sets of 3 repetitions when bench press or half squat conditions were performed and 2 sets of 3 repetitions of each exercise when bench press plus half squat condition was performed at 80% 1-repetition maximum, lifting the load at maximum speed. To assess the serve velocity and accuracy, all participants performed 32 flat serves after the HLRE, divided into 4 sets of 8 serves (0, 5, 10, and 15 min postexercise), resting 20 seconds between serves, and 2 minutes and 40 seconds between sets. There were no significant (P > .05) differences in ball velocity and accuracy following each recovery time and exercise, compared with the basal situation. These results suggest that complex training using HLRE is not a useful method for eliciting the postactivation potentiation effect in tennis serve and does not have any effect in serve accuracy in young competition tennis players.
