Abstract
Tennis is a very popular sport that has been growing in numbers over the past couple of decades. This sport consists of many complex actions/movements that put quite a lot of stress on the upper, abdominal, and lower body. Along with physical stress, tennis can also be very mentally draining to the point where the player is forced to keep a clear mind. Throughout the past couple of years, research has proven that the serve is the most energy draining stroke in the whole game of tennis. Along with this, more research has been done on EMG (electromyography) to help to prevent possible sports related injuries. The purpose of the study was to see if there was a correlation between the muscle activation levels of the anterior deltoid while performing a serve and the speed of the serve-return. It was believed that when the activation levels increased, the speed of the serve-return would increase with it to compensate for the “extra muscular effort” put into the serve. Two varsity high school tennis players were used in the study. One player served 30 times with an EMG device on, while the other player returned the serve 30 with the sensor on to detect the speed of the stroke. After the data was analyzed, it was concluded that there is a strong correlation of 79.48% between the serving speed and the muscle activation levels on the anterior deltoid from the serve return. The null hypothesis was successfully rejected, and both hypotheses of the study were confirmed.
