Have you ever watched tennis – particularly the women’s professional tennis association – and wondered why the athletes grunted as they struck the ball? Though I cannot speak on behalf of any of the players, my assumption was that it increased the attention and ultimately performance of the athlete.
According to research by Amy Welch & Mark Tschampl, I was half right, and the grunting does improve performance, but the boost is related to increased strength and not increased attention. Specifically, the investigators found that the strength of 25 expert and 25 novice martial artists as measured by a handgrip strength test was significantly higher when the martial artists grunted or made some similar verbal outburst. In applying these results to a business setting, next time you have to move a file cabinet or other heavy object, grunt at what you feel is an appropriate level, and if your coworkers give you a funny look, just inform them that you are implementing the latest state-of-the-art evidence-based practice.
