Discussion On The Relationship Between Energy Consumption And Movement Characteristics Of Badminton Fitness

The aim of this research: this thesis is to obtain the situation of gases metabolism(heart rate,maximum oxygen uptake,oxygen pulse,energy consumption,etc.)of each subject in a badminton match.Through the whole process of monitoring and telemeter of badminton fitness people in a single match,the writer uses high-speed camera shooting a video of the whole match.From the data of badminton fitness people,the physical index features and energy consumption features would be analyzed and energy consumption should be calculated.Also the writer counts the application of basic skills of each subject,and analyzes the relation between the basic skills and skilled movement features.Research Objects and Methods: Eight male badminton amateurs in Xi'an Physical Education University were selected as the subjects.The CORTEX-3B portable cardiopulmonary function telemetry instrument was used to monitor the metabolic status of the subjects during the badminton movement by using the literature method,the expert interview method,the experimental method,the video observation method and the mathematical statistics method.And video recording uses CASIO-FH25 high-speed camera,the use of the United States APAS image analysis technology,mathematical statistics using Excel tools to calculate and statistics,the use of SPSS17.0 software using Pearson correlation analysis to provide badminton training data for the public fitness people,and give reference for badminton teaching.After an experimental analysis,the following results were obtained: 1.The average heart rate in a badminton competition was about 173 beats / min;the average oxygen pulse in the exercise was about 16.44 ml;the maximum oxygen uptake in exercise was 3.387 L / Min.2.The average energy consumption of a badminton player's sport is 460.01kJ;the net energy consumption is 526.63 kj,the average time is 7.8min in the race,and the recovery period is about 4.89 min.3.Badminton competition in a badminton game in the average number of batting times 103 times / Board;badminton game in the mobile application is the most positive move;left rear movement and exercise energy consumption is highly correlated r = 0.808.4.Badminton game in the front of the field picking ball technology the largest number of applications,about 23 times / Bureau,in which the post-field splitting technology and exercise energy consumption correlation;backcourt and recovery period of energy consumption is highly correlated r = 0.826.5 The high-speed backcourt movement and the exercise energy consumption of a badminton player 's badminton competition are highly correlated r = 0.842;the correlation coefficient between low-speed back-field movement and recovery period energy consumption is large.Experimental conclusion: 1)Public Fitness Badminton game in the direction of the application is the most moving forward;left rear movement and exercise energy consumption is highly related.2)The number of front-end picks is the largest in the badminton,and there is a great correlation between the post-field splitting technique and the energy consumption of the exercise.The backcourt is highly correlated with the energy consumption during the recovery period.3)The high-speed backcourt movement in the badminton competition of the public fitness person is highly correlated with the energy consumption of the movement;the correlation coefficient between the low-speed backcourt movement and the recovery period energy consumption is large.
