Not just tennis, grunting helps improve a player’s performance across sports disciplines: Report

A new study has found that yelling during a game, not only helps distract opponents and onlookers but also helps one exert more power.

It might force a few spectators to cover their ears, but grunting helps players improve their performance across sports disciplines, not just tennis, a new study has found.

While there have been numerous studies that prove grunting to be a source of spurt in power for tennis player, they did not consider if the concept held true through across the sport. According to a report in The New York Times, other than backhands and ground-strokes, the squeals during physical activities help people exert more power in all sporting activities.

To prove their synopsis, scientists decided to look closely at mixed martial arts and grunting. The sport was chosen as it, like tennis, needed sudden movements. Also, unlike tennis, martial arts does not involve inherent noise, the report stated.

The experiment deemed that if an onlooker struggled to judge a kick or a punch when someone grunted, then the distraction could be attributed to the yell and not due to some other reason.

For the experiment, as many as 20 male and female martial arts practitioners were recruited. All were asked to kick a heavy bag fitted with a device to measure force.

They were asked to kick the bag both as they yell and while remaining silent. The videos of these kicks were shown to 22 undergraduate students. The footage showed the athletes’ feet advancing rapidly towards those viewing it.

The students were asked to decide whether the kick would land high or low and press a corresponding computer key. During half of the kicks, a standardised grunting sound accompanied the motion of the kick. There was no sound on all other instances.

Upon examining the data, the researchers concluded that grunting while kicking had improved the martial artists’ power by almost 10%. Also, the students were found to be slower in their response time while watching the videos accompanied with the grunting noise.

These results showed that a “grunter” drew advantage due to the distraction and proved to beneficial for exerting more power.

Movies can make you leap beyond what is possible

Movies have the power to inspire us like nothing else.

Why do we love watching movies? The question might be elementary, but one that generates a range of responses. If you had to visualise the world of movies on a spectrum, it would reflect vivid shades of human emotions like inspiration, thrill, fantasy, adventure, love, motivation and empathy - generating a universal appeal bigger than of any other art form.

“I distinctly remember when I first watched Mission Impossible I. The scene where Tom Cruise suspends himself from a ventilator to steal a hard drive is probably the first time I saw special effects, stunts and suspense combined so brilliantly.”

Beyond the vibe of a movie theatre and the smell of fresh popcorn, there is a deeply personal relationship one creates with films. And with increased access to movies on television channels like &flix, Zee Entertainment’s brand-new English movie channel, we can experience the magic of movies easily, in the comforts of our home.

The channel’s tagline ‘Leap Forth’ is a nod to the exciting and inspiring role that English cinema plays in our lives. Comparable to the pizazz of the movie premieres, the channel launched its logo and tagline through a big reveal on a billboard with Spider-Man in Mumbai, activated by 10,000 tweets from English movies buffs. Their impressive line-up of movies was also shown as part of the launch, enticing fans with new releases such as Spider-Man: Homecoming, Baby Driver, Blade Runner 2049, The Dark Tower, Jumanji: Welcome to the Jungle and Life.

“Edgar Wright is my favourite writer and director. I got interested in film-making because of Hot Fuzz and Shaun of the dead. I love his unique style of storytelling, especially in his latest movie Baby Driver.”

These movies help us escape the sameness of our everyday lives; expanding our imagination and inspiring us in different ways. The movie world is a window to a universe that is full of people’s imaginations and dreams. It’s vast, vivid and populated with space creatures, superheroes, dragons, mutants and artificial intelligence – making us root for the impossible.
