New energy composite is an advanced material that can replace the traditional single metal material, especially the newly developed or developed material with superior performance. At present, the material is widely used in automobile manufacturing and other fields, but there is a lack of development and application of the material in the field of sports. To solve these problems, this paper puts forward the application of new energy composites in sports facilities and fitness equipment. In this paper, the testing methods of new energy materials, including thermoelectric testing method and energy absorption testing method, can quantitatively evaluate the properties of a kind of new energy composites and point out the direction for the development of materials with high thermoelectric properties and high-energy absorption and consumption properties. Then, through the preparation experiment of new energy materials, this paper studies the preparation process and self-shrinkage test of carbon nanomaterials. Finally, it is proposed to use carbon nanomaterials in the sensor design of health monitoring data acquisition system. The experimental results show that when the water ash ratio is low, the self-shrinkage value of carbon nanomaterial slurry is 74.68% lower than that under the original conditions. In the experimental study of omnidirectional monitoring characteristics, through the repeated tensile tests of rectangular sensor and omnidirectional sensor at different temperatures, it is found that the sensitivity coefficient of the sensor made of carbon nanomaterial is between 55.8 and 60.4, and the maximum fluctuation is only 5. This fully proves that the carbon nanotube omnidirectional sensor has omnidirectional detection ability.

Introduction: Athletes’ physical fitness is an important factor in achieving good results in the game. Exercise and physical skills training are important means of improving competitive sports. No matter the type of sporting event, there are strict regulations on players’ physical fitness. Objective: Analyze the special methods of physical exercise to improve the physical quality of athletes. The results can provide a reference for coaches to formulate more scientifically specific training programs for athletes. Methods: Several athletes with certain sports skills are selected as subjects. The objective of this work is to detect the level of physical fitness of the athletes. And based on this, a statistical analysis of their motor function was performed. Finally, an empirical study is conducted using mathematics and statistics. Results: The difference between the athletes was statistically significant (P<0.05). There were significant differences in athletic ability, physical attractiveness, and body mass among the special exercises for athletic ability (P<0.05). Conclusion: The methods for improving physical quality in male and female athletes were successful in athletes of different disciplines. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
