OTIMIZAÇÃO DA POSTURA NA NATAÇÃO BASEADA NA MECÂNICA ESPORTIVA

Abstract

ABSTRACT Introduction Speed and posture are two determining factors for the success of swimmers. Posture optimization can make athletes’ actions more standardized and improve their speed at a competitive level. Objective Explore the optimization of swimming posture based on sports mechanics. Methods In the controlled experiment, the control group was given routine training, while the experimental group was given sport mechanics-based swimming posture optimization training. A duration of 60 minutes daily, three times a week. The experiment was completed in 6 weeks. Data by computerized cinematography were extracted using the reflective marking ball technique. Its mechanical motion and time consumption characteristics were collected before and after the experiment, cataloged, compared, and discussed statistically. Results Daily and posture optimization training can improve athletes’ body extension range. The effect of the experimental group in improving the range of body extension was shown to be greater than the standard training and slightly greater than the daily training by shortening the action time. Conclusion The posture optimization scheme for swimming based on sports mechanics can improve athletes’ extension range and speed. Physical education teachers and coaches should further optimize and promote the swimming posture optimization scheme to improve the performance of their athletes.
