Make Some Noise For Harder Hits

Make Some Noise For Harder Hits If you've watched any professional tennis, you've heard players grunt audibly when swinging at the ball. Is this just a habit, or is there any valid science behind the practice? A study published in the Journal of Strength and Conditioning Research suggests grunting helps you return the ball faster without expending more energy.

Ten male and female Division I college athletes returned a tennis ball forehand and backhand while grunting or being silent. Each condition lasted for 2 minutes, and they were given a minute to rest between each of the four sessions. Grunting helped tennis players increase ball velocity by 3.8% with no significant metabolic cost and the hits became faster as the simulated match progressed.

True Strength Moment: Martial arts practitioners have been known to yell when striking, and more than a couple weight lifters make noise when hoisting those last few reps at the end of the set, so these findings aren't without precedent. See if the technique helps you put a little something on the ball.
