INTRODUCTION

Flexibility is an essential physical quality of the human body. It refers to the movement ability of human joints in different directions and the stretching ability of soft tissues such as muscles and ligaments. Speed skating, ice hockey, freestyle skiing aerial skills, curling, alpine skiing, ice ballet, and other winter sports have high requirements for athletes’ flexibility.¹ The development of flexibility in athletes can make movements more graceful and coordinated and improve muscle strength. It has a positive effect on preventing injuries, reducing injury accidents, and promoting physical recovery. Athletes who correctly perform stretching exercises can improve their flexibility and sports skills.² Most coaches and athletes of ice ballet in China have realized the importance of stretching exercises. Coaches have included it as an essential part of the conditioning program. The author uses the data access method to study human bones and joints’ structure, range of motion, and influence factors. To investigate and analyze the opinions, views, and opinions on the factors affecting the flexibility of ice ballet athletes. At the same time, this paper studies the characteristics and differences of the body composition changes in the pre-competition training of elite ice ballet athletes.³ In this way, the characteristics of changes in body composition of elite ice ballet athletes before the competition and their impact on body flexibility were discussed.

METHOD

Research objects

This paper selects ten ice ballet athletes as research objects. ( Table 1 ) This paper used the segmental bioelectrical impedance body composition tester to measure 20 electrical impedances in 5 segments. Current flow 250μA. There are eight electrodes on the hands and feet. We measure body impedance in sections.⁴ The calculation of the body composition results is done by the module that comes with the instrument. Tested body composition indicators are body fat percentage (%), body fat mass (kg), muscle mass (kg), lean body mass (kg), body water content (L), and body flexibility.

Basic information of elite ice ballet athletes ( χ ± S ).

Gender	N	Age	Training years	Height (cm)	Weight (kg)
Male	5	17.5±4.8	10.5±4.7	174.6±3.36	65.4±2.88
Female	5	17.2±2.2	10.8±2.8	167.2±3.72	50.6±3.38

The flexibility of ice ballet athletes

W 1 indicates torso weight. W 2 represents the combined weight of the head, neck and arms. Represents FC erector spinal muscle strength that maintains flexion of the spine. θ represents the angle of flexion of the spine to the ground.⁵ S represents the shear component. P is the reaction force of S .

When a speed skater is sliding, the forward angle of the trunk is 20º. According to the Chinese human body link parameters, we know that the trunk accounts for about the entire body weight 43%, W 1 = 25.8kg. The head, neck and arms account for about the entire body weight 17%, W 2 = head and neck + arms = 10.2kg. We can get L 1 = 32 cm, L 2 = 55 cm, D = 5 cm (the erector spinae 5 cm from the spine).

$\sum M=0,F^{\ast }D=W{1}^{\ast }L1+W2\ast /L2$

$F=(W{1}^{\ast }L1+W2\ast /L2)/D=2773.2N$

The erector spinal muscle strength that maintains the forward flexion of the spine is F = 2273.2 N

The total extrusion force is $N=F+(W1+W2{)}^{\ast }\sin {20}^{\circ }=2896.3N$

$NX=N^{\ast }\cos {20}^{\circ }=2721.6N;NY=N^{\ast }\sin {20}^{\circ }=990.6N$

The sheer force is $S=(W1+W2{)}^{\ast }\cos {20}^{\circ }=338.3N$

Statistics method

This article regularly measures the proportions of body composition and nutrients in athletes, and we process the data in Microsoft Excel 2016. We calculate the mean and standard deviation.⁶ A one-sided test P<0.05 was considered significant.

There is no need for a code of ethics for this type of study.

DISCUSSION

Analysis of body composition characteristics of elite ice ballet athletes

Ice ballet is a skill-oriented sport that is difficult to perform. Ice ballet is a sport with anaerobic energy supply as the primary and aerobic energy supply as a supplement. VO2 max training stimulates the production of mitochondria in red blood cells. Mitochondria are energy factories.⁹ An adequate energy supply can promote the enhancement of cytochrome oxidase activity. The number of capillaries also increases. This accelerates the diffusion rate of lactic acid. It enhances the body’s ability to tolerate lactic acid. Some scholars believe that the absolute value of VO2 max is a better predictor of aerobic capacity in ice ballet athletes. There is a particular relationship between the performance of ice ballet athletes and their weight. In the daily systematic training of ice ballet athletes, it is indispensable for coaches and researchers to monitor the body composition of athletes in real-time. An athlete’s body composition is related to certain physiological functions and athletic ability. Both Tables 2 and 3 show that the body composition of the athletes gradually decreased. They achieved optimal body weight, body mass percentage, lean body mass, and other metrics during the competition period. Ballet on ice is a project that is difficult to express. Athletes have muscular aerobic endurance.¹⁰ An athlete’s body composition also has many degrees of influence on its specific movement speed and specific explosive power. An athlete’s performance in competition may also reflect body composition characteristics.

Influence of body flexibility on gracefulness in an ice ballet

Sports training theory believes that flexibility develops quickly and is easy to achieve. Flexibility disappears when athletes stop training for a little longer. Athletes in the range-of-motion stage should schedule daily exercises to develop flexibility. Athletes can schedule no more than four times a week in the hold phase. However, exercises to develop or maintain flexibility should be scheduled during any training period throughout the year. Ice ballet athletes have different training methods, means, quantity, and intensity, and their flexibility shows significant differences.¹¹ Exercises that develop flexibility allow each joint to reach its maximum range of motion. In this way, the potential of the athlete can be fully tapped. This improves flexibility.

The athlete’s flexibility training load intensity is mainly controlled and arranged by the athlete’s “subject kinematic perception.” The effort can be reduced when the athlete feels muscle soreness. Hold on when the athlete feels muscle pain. The athlete needs to stop training when the muscles feel numb. Generally speaking, the effect of long-term moderate-intensity pulling exercises is better than that of short-term high-intensity exercises. Flexibility training load intensity determines the effect of developing flexibility.¹² The amount of time an ice baller can practice to develop flexibility should be based on the purpose of the training session. For training sessions that develop athletes’ flexibility, the practice time should be set between 60-90 minutes. Exercises to develop flexibility in standard training sessions should be performed after warm-up activities. The practice time is generally about 20 minutes.¹³ Although stretching exercises for relaxation can also promote the development of flexibility, long-term muscle work will cause fatigue. Decreased elasticity, stretchability, and excitability result in imperfect muscle contraction and relaxation. Muscle groups do not work in harmony, resulting in reduced joint flexibility. At this time, it should be mainly to eliminate the body’s exercise fatigue. Practice time is generally about 35min or more extended. The time for each group of continuous practice is 6-12s, and the swing action can be slightly longer. When doing static exercises, the athlete can stay for a fixed time of about 30s. Practice time plays an essential role in developing the flexibility qualities of ice ballet athletes.

CONCLUSION

Changes in the body composition of elite ice ballet athletes before competition may impact the athlete’s flexibility. There are differences in body composition between elite male and female ice ballet athletes. It is mainly manifested in the percentage of body fat (fat content. This may also be one of the factors that male athletes are superior to female athletes in certain sports. The muscles, tendons, and ligaments have better elasticity and stretchability. Athletes should strengthen their training body flexibility in daily training.
