EFFECTS OF PILATES ON AEROBIC PERFORMANCE OF COLLEGE STUDENTS

ABSTRACT Introduction: The Pilates is a training method that aims to improve body awareness for movement re-education, bringing muscular and mental balance. It is believed that these benefits can effectively improve the flexibility of female university aerobics students. Methods: 90 female college students in the optional aerobics course were selected and divided into two groups. Data from the experimental and control groups were evaluated for comparison before and after the experiment. The aerobic exercises of the two groups of female university aerobics students were scored, aiming to compare and explore which training method was more effective. Results: The baseline time and pace score in the Pilates intervention was changed from 2.35±0.71 to 2.55±0.76, a movement set changed from 3.86±0.98 to 4.01±1.07, movement performance from 1.67±0.61 to 1.72±0.57, and foot skills from 1.40±0.48 to 1.41±0.50. The mean aerobic movement performance score changed from 62.45 to 80.53, an increase of 18.08 points. Conclusion: The Pilates training can effectively improve the aerobic performance of female university students. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.


INTRODUCTION
When training Pilates, we should activate the exhausted and long-term undeveloped muscle tissue, strengthen the basic core function, strengthen the correct rib breathing, strengthen the coordinated mental control of various muscle tissues, and enhance the nerve connection ability by collecting more deep muscle tissue, improve the function of small muscle groups, effectively control the movement of the human body, improve the physical quality, strengthen the stability of the trunk, joint flexibility Body balance, symmetry, and movement coordination. 1For example, the spine extension in Pilates is a classic function of strengthening the flexibility of the spine, which can not only improve the body curvature of the spine, but also increase the muscle strength of the abdominal muscles and the dorsal extensor muscles; Shoulder bridge action is a classic action to the hamstring muscle, which can activate the hamstring muscle, strengthen the hip joint extension and gluteus muscle, and effectively increase the stability of the trunk. 2 Pre-support and advanced movement are also one of the main movements to increase the stability of the trunk.The correct breathing mode can adjust the proper arrangement of the body joints. 3Aerobics is a project that can well reflect the overall quality of human speed, strength and flexibility, and its sports range includes transitional sports, difficult sports and strategic sports.College students must have good trunk stability, balance, coordination and muscle control ability to make changeable and complex technical movements. 4Good aerobics requires strong core strength as the support of college students.Pilates can effectively improve the stability of the trunk, improve body balance, adjust the flexibility of joints through core strength exercises, and help college students improve their sports skills and quality. 5The focus of this paper is on the improvement and influence of Pilates training on the movements of aerobics college students.Deeply explore the various functions of Pilates training and the related role of aerobics training, which not only modernizes the training methods and methods of aerobics college students, but also provides more innovative training paths for college students to improve the quality of movements. 6

Experimental object
In order to avoid gender differences, 90 female college students in the aerobics optional class were selected, and there was no significant difference in the physical indicators of 90 female college students in the aerobics optional class.The study and all the participants were reviewed and approved by Ethics Committee of Jiangsu Research Institute of Sports Science (NO.JRISS2022FD-19).Before the experiment, 90 female college students were measured with basic body data, including height, weight and age.The average height is 167 cm, the average weight is 58 kg, and the average age is 20 years old.The 90 female college students in the optional sports class were randomly divided into two groups, 45 in each group.One group was the experimental group, and the other group was the control group.45 female college students in the experimental group were trained in Pilates, while the control group was trained in routine aerobics.(Table 1)

Experimental method
First of all, before the experiment, the basic physical quality of 90 female college students in the aerobics optional course was measured.
In addition to the basic height, weight and age, the basic ability of aerobics also needed to be measured, including 1 minute sit-ups, side bridges, waist flexion, waist extension, side throwing medicine balls, plate support, etc., and the comparative analysis of the basic ability data of aerobics was carried out after the experiment, In order to analyze which training mode of general aerobics training and Pilates training has more obvious effect on the ability improvement of female college students' aerobics movement performance.

Experimental variables
The experiment lasted for 12 weeks.During the whole experiment, the independent variable of the experiment was the

The effect of Pilates training on the basic ability of college students' aerobics
Table 2 shows the comparison of the data before and after the experiment on the basic calisthenics ability of 45 female college students in the control group who took 12 weeks of routine calisthenics training.
Under the guidance of coaches and teachers, after 12 weeks of training, the indexes of the control group of routine aerobics training were improved, and the T value was negative.Routine aerobics training can also improve the basic calisthenics ability of female college students, but from the experimental data, the improvement effect is not obvious.We can try to explore more effective training ways to improve the basic calisthenics ability and movement performance of female college students, so as to promote the improvement of female college students' calisthenics skills and movement optimization.
Table 3 shows the comparison of the basic calisthenics ability of 45 female college students in the experimental group who took 12 weeks of routine calisthenics training before and after the experiment.Under the guidance of the Pilates instructor and teacher, after 12 weeks of training, all indicators of the Pilates training experimental group were significantly improved, while the T value was negative.Compared with the routine aerobics training, Pilates can significantly improve the basic ability of female college students' aerobics.Compared with the data before and after the experiment, the improvement effect is very obvious.You can try to regularly increase Pilates training in the aerobics sports elective course to improve the basic ability and movement performance of female college students' aerobics, So as to promote the improvement of female college students' aerobics skills and the optimization of their movements, so as to make female college students achieve better results in the optional sports courses.

Optimization analysis of pilates training on college students' aerobics movement performance
By observing Table 4, it can be clearly found that in the test of basic calisthenics ability of 45 female college students in the sports elective class before the experiment, the time value and basic rhythm were 1.456 ± 0.5353, the complete set of movements was 3.195 ± 1.2393, the movement performance was 1.398 ± 0.5334, and the footwork skill was 1.191 ± 0.3740.After the experiment, the specific index changes of the basic calisthenics ability of 45 female college students in the optional physical education class are as follows: the time value and basic rhythm change is 1.550 ± 0.5456, the complete set change is 3.276 ± 1.1886, the movement performance is 1.492 ± 0.5962, and the footwork skill change is 1.169 ± 0.3931.
After 12 weeks of training in the control group of routine aerobics training, all indicators of basic ability of aerobics have been improved, P value is less than 0.05.After 12 weeks of regular aerobics training, 45 female college students have improved their time value and basic rhythm, complete sets of movements, movement performance, footwork skills and other aspects.Through regular aerobics training, female college students can improve their aerobics movement proficiency, and then improve the beauty and movement performance of aerobics movements.However, it needs continuous practice day after day, and the effect is not significant.
By observing Table 5, it can be clearly found that in the test of basic calisthenics ability of 45 female college students in the experimental group in the sports elective class before the experiment, the time value and basic rhythm were 2.358 ± 0.7141, the set of movements was 3.860 ± 0.9847, the movement performance was 1.671 ± 0.61694, and the footwork skills were 1.405 ± 0.4874.After the experiment, the specific indicators of the basic ability of aerobics of 45 female college students in the optional physical education class changed as follows: the time value and basic rhythm changed to 2.553 ± 0.7614, the set of movements changed to 4.015 ± 1.0713, the movement performance 1.721 ± 0.5772, and the footwork skill changed to 1.417 ± 0.5040.
After 12 weeks of training in the experimental group of Pilates training, all indicators of the basic ability of aerobics of 45 female college students have been improved, P value is less than 0.05.After 12 weeks of routine Pilates training, 45 female college students' time value and basic rhythm, complete sets of movements, movement performance, footwork skills and other aspects have improved significantly.Through Pilates training, female college students' body flexibility can be improved, which is crucial for female college students in aerobics, and then improve the consistency of aerobics movements, with significant results.
Figure 1 shows the change of aerobics performance score of female college students in the control group and the experimental group before and after the experiment.Before the experiment, the average score of aerobics performance of 45 female college students in the control group of general aerobics training was 63.23, and the average score of aerobics performance of 45 female college students in the experimental group of Pilates training was 62.45.After 12 weeks of experiment, The average score change of 45 female college students in the control group of general aerobics training is 75.55, and the average score change of 45 female college students in the experimental group of Pilates training is 80.53.Before the experiment, the control group scored 0.78 points higher than the 45 female college students in the experimental group in aerobics.After 12 weeks of experiment, the experimental group scored 4.98 points higher than the 45 female college students in the control group in aerobics.After the experiment, the average performance of the 45 female college students in the experimental group was significantly better than the control group.
