| Objective:Heart rate is often used to reflect the exercise intensity, physical load and physical condition. High strength, and physical overload problem most direct expression of loss and failure to increase the rate of athletic ability and accuracy of movement, this is an important factor in technical stability. In this paper, the evaluation of heart rate in view of the application serve, forehand and backhand technical stability study, the use of monitoring instruments to the rate of change of the game of tennis center for analysis and discussion.Methods:Catapult sport integrated monitoring equipment, the Beijing Sports University, the university sports teams eight men athletes heart rate changes in the simulation game to monitor the use of Sony cameras for the entire shoot, record game play situations technical level athletes. Heart rate data and analysis tools for video recording and statistical post-consolidation ratio of integrated use Sprint5.1 athletes.Results:1. The simulation game, tennis players in maximum heart rate (66%-70%) range, out of the best, in the maximum heart rate (66%-70%) (71%-80%) Interval second serve the best results. The maximum heart rate (over 81%) and two out of the range are the lowest-fat effect; out of heart failure at the highest 63% of the number of percentage, the percentage of 37% the number of two faults; unadjusted number of people out of technology as a percentage of 75%, two hair technology unadjusted number of percentage 87.5%; technical adjustment as the main way to increase the rotation.2. The simulation game, the tennis player in maximum heart rate (66%-70%) Interval best forehand in the maximum heart rate (over 81%) the effect of the minimum interval forehand; maximum heart rate is the ball when hit The number of ball turnovers percentage was 37%; unadjusted number forehand technique percentage is 50%; technical adjustments to the Internet to attack the opponent pressures increase, the consumption of physical opponents, waiting for the opponent turnovers as the main way to take the initiative.3. The simulation game, the tennis player in maximum heart rate (65% less) range best backhand in the maximum heart rate (over 81%) the lowest range backhand effect; when the maximum heart rate as a percentage of the number of backhand errors 37%; unadjusted number backhand technique percentage of 63%; technical adjustments to change the grip way, consumption as the main way of physical opponents.Conclusions:1. simulation game, players in maximum heart rate (over 81%) and two out of the range are the lowest-fat effect; out of heart failure at the highest percentage of success is higher than the percentage of success is lower than the percentage of two faults percentage; technology is not The number is higher than the percentage adjustment to adjust the number of percentage.2. The simulation game, players in maximum heart rate (over 81%) the lowest range forehand effect; in the percentage of maximum heart rate forehand errors lower than the percentage of success; technology unadjusted Number Percentage Number Percentage Adjustment flat.3. Analog competition, athletes in maximum heart rate (over 81%) the lowest range backhand effect; in the percentage of maximum heart rate is lower than the success percentage backhand errors; technical unadjusted percentage is higher than the number of adjust the number of percentage. |
