Spectators react amused or annoyed when some of the tennis pros at blow groan loudly. Professionals like Martina Navratilova will feel this but to the part irritated, and at a disadvantage. The former world rank list first says, the moaning would drown out the slap noise and thus make it difficult to predict the trajectory say in an unfair way. A Team from the University in Jena, Germany, has now investigated whether this is true.
By manipulating the volume of the Stöhnens in video recordings, has been examined by the Team led by Dr. Florian Müller and Prof. Dr. Rouwen Cañal-Bruland from the Institute for sports science, Friedrich-Schiller-University of Jena, whether it has an effect on the expectations of experienced tennis players. In fact, this assumed that the Ball would, the fly, the louder was the moan. Nevertheless, the " were;Gegenspieler" does not irritate and the direction of the flight path could tell very accurately in advance, i.e., a General distraction effect was not observed by the moaning.
"We assume that players take into account the physiological benefits, which enables the moaning,the " Miller said, because a strong Exhale activates the abdominal muscles, which means more force is added, the harder hits and higher ball speeds allows. The authors conclude that tennis players could lead their opponent, theoretically, deliberately misleading, by moans hard blows with a quiet and soft with loud.
Apparently, the other senses are next to the See impressions in the Tennis of importance, which should be taken into account by the science stronger. Therefore, the Team wants to stay on the Ball and the phenomenon – as under real conditions on the course – to further investigate.
