Increasing the effect of speed and strength training using the CrossFit system in female athletes

Abstract

Enhancing speed-strength abilities is a key focus in physical training. Developing more effective pedagogical methods to cultivate this motor quality is crucial for educational and training activities. Purpose: This study aims to evaluate a methodology for improving the speed-strength qualities of schoolgirls aged 16-18 by implementing the CrossFit training system during extracurricular time in the school sports program. Materials and Methods. The research was conducted at a secondary school in the Siberian Federal District. We observed 24 girls aged 16-18 (17.2±0.8 years), who were divided into 12 people into the control (CG) and experimental groups (EG). They attended the school general physical training section three times a week during free time. Each training session lasted 90 minutes. Training in both groups was conducted according to the traditional program for developing general physical qualities. The EG girls used our improved method of developing speed-strength qualities using the CrossFit training system, which took up 30-40% of the total time of each lesson and was included in the main part of the educational and training sessions on general physical training for three months (from February to April). Each set of CrossFit exercises had elements of a speed-strength focus. The performance of loads in aerobic and anaerobic modes was combined. At the beginning and end of the research project, the state of speed-strength qualities of girls in both observed groups was assessed using motor tests. Results. The results of testing motor qualities established a higher efficiency of the improved method of improving speed-strength qualities in EG girls, where the CrossFit training system was used compared to CG. In EG girls, the values of the indicators of all speed-strength tests were significantly higher than the results of testing the girls in the control group. Conclusions. The proposed method for improving speed-strength qualities in girls aged 16-18, which uses the CrossFit training system, can be used in other educational institutions during additional time spent in the sports section.
