INTRODUCTION
Aerobics is a sport in which the whole body is involved in performance. Body movements are the basis for aerobics, and aerobics projects account for a very high proportion of aerobic exercise.11 Yan M. Research on the arrangement and visual design of aerobics under the new situation. Int Core J Eng. 2019;5(9):170-3. Aerobics has a certain influence in China. The difficulty of the event can be adjusted according to the age of the participants. Therefore, aerobics is an inclusive sport.22 Zaletel P, Gabrilo G, Perić M. The training effects of dance aerobics: A review with an emphasis on the perspectives of investigations. Coll Antropol. 2013;37(2):125-30. Secondly, since there are no special requirements for the venue, the specific types of aerobics can be adjusted according to the site conditions. Long term aerobics projects can help students shape their bodies, cultivate good posture, and enhance their physical quality.33 Douris PC, McDonald B, Vespi F, Kelley NC, Herman L. Comparison between Nintendo Wii Fit aerobics and traditional aerobic exercise in sedentary young adults. J Strength Cond Res. 2012;26(4):1052-7. And it can cultivate students’ tenacious will quality in this critical life stage of university. Help students maintain a healthy state by improving their physical function, coordination and stability. And aerobics is more helpful for students suffering from obesity.44 Rokka S, Mavridis G, Kouli O. The impact of exercise intensity on mood state of participants in dance aerobics programs. Stud Phys Cult Tour. 2010;17(3):241-5. Long time aerobics can help students with obesity problems to speed up fat burning. It has the effect of slimming and shaping. Since the development of aerobics, there have been traditional physical fitness events developed into competitive sports. With the development of aerobics, the intensity of daily training also increases, which puts forward certain requirements for students’ body posture and sports performance.55 Héroux M, Janssen I, Lee D, Sui X, Hebert JR, Blair SN. Clustering of unhealthy behaviors in the aerobics center longitudinal study. Prev Sci. 2012;13(2):183-95. Therefore, through the analysis of the students’ body posture, the training methods of sports expressiveness suitable for aerobics can effectively help the development of aerobics courses in colleges and universities, and provide powerful help for students to participate in aerobics.66 Bryukhanova NA, Bulgakova OV, Mokrova TI, Bogashchenko YA. Determination of possibilities of the use of high-intensive trainings facilities on lessons health aerobics. Physical Education of Students. 2013;17(2):25-9. In order to study the effect of body posture training on the improvement of college students’ performance in aerobics, this paper selects a freshman aerobics major in a university to train them in body posture, and analyzes the results.77 Haffer H, Popovic S, Martin F, Hardt S, Winkler T, Damm P. In vivo loading on the hip joint in patients with total hip replacement performing gymnastics and aerobics exercises. Sci Rep. 2021;11(1):13395.
METHOD
Selection and grouping of aerobics experimenters
After defining the experimental scheme, 20 researchers were selected for random sampling, and they were divided into 10 experimental groups and 10 control groups. The study and all the participants were reviewed and approved by Ethics Committee of Ningbo Polytechnic (NO.NBPLT20PT102). The basic information is shown in Table 1, with little difference between them.
Experimental implementation plan
The experiment lasted for 9 weeks, with three training sessions per week. Among them, the control group followed the traditional aerobics movement training, and the experimental group introduced dance based on the aerobics movement training. Through in-depth study of the competitive status of excellent athletes, and with the influence of dance teaching, students’ quality in body posture was improved.
Before the beginning of the experiment and after 9 weeks of training, the experimental group and the control group were measured, including the basic physical indicators, the flexibility indicators of athletes, and the scores of movement performance and total scores, to analyze the teaching effects of the two methods.
RESULTS
Effect of body posture training on physical fitness of aerobics students
Aerobics seems to be light, but it actually takes a lot of physical strength. Therefore, if students want to give people a light posture when performing aerobics and improve their expressiveness, they must strengthen the optimization of their own physical ability. Five indicators, including one minute push up, 30 seconds standing and lying up, one minute two head up, one minute sit up and one minute rope skipping, were selected as the criteria for judging physical fitness. The specific conditions before and after the experiment are shown in Table 2.
The Influence of Body Posture Training on the Physical Ability Index of Students Majoring in Aerobics.
The number of push ups in the experimental group was (26.20 ± 12.9835) one minute before the experiment, and increased to (34.55 ± 12.4508) after the experiment, an increase of 24.1792%, significantly higher than 8.9179% in the control group; The times of standing and lying in the experimental group were (16.69 ± 2.2957) times 30 seconds before the experiment, and increased to (17.57 ± 2.1284) times after the experiment, an increase of 5.0261%, higher than 4.7094% in the control group; The number of starts at both ends of the experimental group was (16.89 ± 4.8648) times one minute before the experiment, and increased to (21.99 ± 5.4711) times after the experiment, an increase of 23.1607%, significantly higher than 5.1221% in the control group; The number of sit ups in the experimental group was (38.25 ± 8.6769) times in the first minute before the experiment, and increased to (43.19 ± 5.4146) times after the experiment, an increase of 11.4444%, significantly higher than 3.9334% in the control group; The number of rope skipping in the experimental group was (149.36 ± 14.4233) times in the first minute before the experiment, and increased to (163.20 ± 8.5110) times after the experiment, an increase of 8.4802%, significantly higher than −1.5340% in the control group.
The flexibility of aerobics is the key to reaching the standard of aerobics movement. If the body is not flexible enough, it will make the movement stiff and show no aesthetic feeling of aerobics. Therefore, five indicators, including right vertical fork, left vertical fork, cross fork, sitting forward bend and shoulder turn, are selected as the criteria for judging the flexibility of aerobics special students. The specific data statistics and changes before and after the experiment are shown in Table 3.
The Influence of Body Posture Training on the Flexibility Index of Students Majoring in Aerobics.
The height of the right crotch of the experimental group was (18.17 ± 7.5675) cm before the experiment, and decreased to (10.15 ± 5.3910) cm after the experiment, optimizing 78.9436%, significantly higher than 11.0966% of the control group; The height of the left crotch of the experimental group was (21.65 ± 9.2145) cm before the experiment, and decreased to (13.08 ± 6.8825) cm after the experiment, optimizing 65.4739%, significantly higher than 17.5397% of the control group; The crotch height of the experimental group was (28.72 ± 9.5804) cm before the experiment, and decreased to (19.07 ± 6.1609) cm after the experiment, which was 50.6148% optimized, significantly higher than 16.8785% of the control group; In the experimental group, the forward bending distance of the sitting body before the experiment was (9.43 ± 5.0933) cm, and after the experiment, it was raised to (14.04 ± 3.7669) cm, which was 32.8087% optimized, higher than 22.0075% in the control group; The rotation angle of the shoulder in the experimental group was (44.37 ± 12.4551) ° before the experiment, which was improved to (52.30 ± 14.4253) ° after the experiment, which was 17.8786% optimized, significantly higher than 0.0059% in the control group.
It can be seen from the comparison within the group that the existing aerobics movement skill training in the control group can provide a good optimization effect on flexibility, but the difference is very significant compared with the experimental group, which shows that the existing aerobics movement skill is not as good as the content of dance training in flexibility. Therefore, the introduction of dance art body posture training into aerobics movement training can greatly enhance the flexibility of special students.
The influence of body posture training on the movement performance of aerobics students
Aerobics is the combination of art and sports, and the composition of strength and beauty. Therefore, action performance is a key point of aerobics scoring. The article refers to the scoring standard of aerobics, and selects six indicators for scoring, including musical rhythm, facial expression, norm, strength, range and posture. The specific score changes are shown in Table 4.
The score of music rhythm sense in the experimental group before the experiment was (2.49 ± 0.8061) points, and after the experiment, it rose to (3.75 ± 0.8344) points, which increased by 33.6020%, higher than 20.6288% in the control group; The score of facial expression in the experimental group was (1.78 ± 0.4816) points before the experiment, and it rose to (2.35 ± 0.5813) points after the experiment, an increase of 24.3687%, significantly higher than 5.6642% in the control group; The standard score of the experimental group before the experiment was (2.61 ± 0.7958) points, which was increased to (3.57 ± 0.5093) points after the experiment, 26.9585% higher than the control group's 23.5137%; The score of strength in the experimental group before the experiment was (2.28 ± 0.6258) points, which rose to (3.53 ± 0.9817) points after the experiment, 35.2914% higher than the control group's 19.0861%; The score of the experimental group in terms of amplitude before the experiment was (2.28 ± 0.5390) points, which rose to (2.88 ± 0.6902) points after the experiment, 20.8033% higher than the control group's 13.8676%; The score of posture in the experimental group before the experiment was (2.53 ± 0.7469) points, and it rose to (3.51 ± 0.9888) points after the experiment, an increase of 27.8784%, significantly higher than 14.7975% in the control group.
Finally, the changes in performance scores of aerobics students are compared and analyzed, as shown in Table 5. The total performance score of the experimental group before the experiment was (70.32 ± 7.4688) points, which rose to (80.19 ± 5.4902) points after the experiment, an increase of 12.3078%; The total performance score of the control group before the experiment was (68.13 ± 6.8167) points, which rose to (75.32 ± 5.0801) points after the experiment, an increase of 9.5466%. It can be seen from this that the control group has significantly improved the performance, but there is still a certain gap compared with the experimental group, which proves the advantages of introducing dance teaching body posture training into aerobics special training.
DISCUSSION
Since the aerobics project exhibition, the aerobics body posture training is the core training content of the aerobics project. The high-level aerobics competition is developing towards a more difficult and artistic direction. All technical movements can be completed on the basis of stability. The high degree of action completion can reflect the aesthetic appreciation value. The second is the cultivation of temperament. The expression of temperament is based on the comprehensive consideration of external temperament and internal temperament. Temperament can directly reflect a person's mental outlook. Different temperament can have different artistic expression in aerobics. Through daily posture training, students’ temperament can be cultivated imperceptibly. What is outstanding is the cultivation of students’ personality, which can make the artistry more prominent and improve the artistic level of the project by expressing beauty in elegant temperament. In the process of posture training, quality attribute training is indispensable. The purpose of improving physical fitness is to improve students’ physical functions, and ensure that students can have good physical fitness as the basis for complete performance of technical actions. In the aerobics competition, the posture of each part of the body is a factor that directly affects the final result of the competition. Therefore, in the daily training link, we should ask ourselves to have enough movement completion, and good body posture cannot be rushed to success. Through accumulated training, the beauty of posture is gradually formed. In the training process, strengthen the training of these body control. Difficult technical movements usually require their own control to reach a certain standard. The training of body control can ensure students to complete the whole set of movements with high standards. The last is to improve the project level by improving the basic physical quality. Basic physical fitness refers to a series of sports attributes such as strength, speed, endurance, physical strength, flexibility and flexibility. In view of these sports attributes, it is an important part of cultivating one's own posture to carry out targeted strengthening training in combination with one's own weak links.
CONCLUSION
There is such a misunderstanding in the teaching and training of aerobics, which simply regards aerobics as a sport and only pays attention to the standard of action in the process of sports, but ignores the expression of action and the presentation of the overall atmosphere. Therefore, this paper combines the body posture training of dance teaching with the existing aerobics expressive force training to design the body posture training of aerobics, And it is applied in the aerobics teaching of a university. The research results show that body posture training can better optimize students’ physical fitness and flexibility, improve their artistic expression ability, and ultimately improve the score of aerobics expression, so it is worth promoting.
