The Secondary Tennis Players’ Reaction Time And Heart Rate Influence On The Service Qualities

Heart rate as easy to measure and no traumatic physiological indexes, is often used for monitoring the exercise intensity in the movement time and an important index of physiological load, at the same time, the heart rate is the sensitive indicators reflect the body’s energy metabolism, reaction time and judge athletes in response to stimulation of simple or complex choose one of the important indicators, this paper in view of the applied research, using remote sensing analysis of heart rate and reaction time to find a different heart rate of receiving the quality change rule and reaction time and receiving quality there is a certain relationship. This experiment adopts the SONY digital camera (HDV1080i), analyzed the athlete (eight secondary level athletes, male) reaction, give participants wear Finland produce polar table, monitoring the tennis athlete’s heart rate changes and real-time, To participants wear Finland polar table production, monitoring the tennis athlete’s heart rate changes and real-time records, using spssl7.0 sorts through the data and statistics. Experiment results is divided into three parts:1. The secondary level athletes at heart rate range of 150-170 times/min receiving quality relative to the heart rate in the range of 110-130 times/min and 130-150 times/min two stage heart rate in the receiving area dealing with the inside and outside, receive the status of the most active, including heart rate range of 150-170/receiving of time-sharing score relative to the heart rate range 110-130 times/min and 130-150 times/min two stage of heart rate more than 33 points and 9 points.2. Secondary level athletes in the right service court receiving quality is significantly higher than the left service court receiving location, the right service court receiving the three heart rate under the scope of the total score is 59 points,68 points and 70 points respectively, the left service court receiving position in three stages of the heart rate of receiving total score of 24 points respectively,39,46 points, in the right service court inside location service quality is higher than the left service court inside, the right service court outside, return of service quality is higher than the left service court outside 3. In the analysis of the reaction time athletes start swinging time and start time of the body has no obvious relation with receiving quality, but the quality in receiving the highest 150-170/distraction rate stage, the right service court outside, receiving the highest score and started from the body to swing the longest interval, the side see athletes earlier respond to judgment and so on to the ball more time to make a judgment and response to receiving a positive impact on the quality., According to experiments, it is concluded that the three parts of results, is to summarize the conclusion as follows:1. Secondary athletes in their heart rate range 150-170/the time receiving the highest quality, stability and receiving points won the best.2. Secondary athletes in the right service court receiving quality is significantly higher than the left service court receiving quality.3. Does not change significantly during different stages of heart rate response, and receiving the quality of the relationship is not significant, but the athletes in the earlier receiving judgement and running and under the premise of receiving swing to prepare more fully receive better effect.
