Analysis of the dynamics of physical development of cadets as a result of the application of crossfit equipment
Purpose: to investigate the impact of classes in the program of physical training of cadets of military institutions of higher education at the stage of primary training with the use of crossfit tools on the physical development of cadets.
Material & Methods: was organized and conducted. anthropometric study and calculation of indices of physical development of cadets. The study was conducted in the sanitary section of the National Academy of Ground Forces named after Hetman Petro Sahaidachny by medical personnel 30 minutes after the ascent.
Results: it was determined that conducting training sessions using crossfit equipment has a positive effect on strengthening the musculoskeletal system of cadets and improving their muscular system (especially the muscles of the back, legs and shoulder girdle). During the study of body weight, there were positive changes in the direction of weight reduction by 3.62 kg (t=2.52; p<0.05) at the end of the experiment; the average value of VL in EG improved compared to the initial data by 245.48 ml (p<0.001), and in EC – by 78.22 ml (p<0.05); the difference between the dynamometry indicators of the left and right hand of the EG at the first and fifth stages of the study was 3.18 kgc and had positive significant changes (t=3.18; p<0.01), the difference between the dynamometry indicators of the left and right hand of the CG was 2.19 kgf and had positive unreliable changes (t=1.85; p>0.05). As a result of the pedagogical experiment, it was determined that the dynamometry indicators of the right and left hands of EG and CG cadets at the end of the experiment differ significantly (p<0.01), which indicates the effectiveness of the physical training program. The chest circumference of the cadets at the beginning and at the end of the experiment has reliably stable results and is only 2.04 cm (p>0.05) and are reliable. As for the Quetelet index, there were positive changes towards improvement, namely: at the beginning of the experiment it was 4.85 g/cm (t=0.69; p>0.05), at the end – 25.80 g/cm (t=4.09; p<0.001), which emphasizes the positive impact of exercise and crossfit.
Conclusions: it has been proven that the application of a physical training program at the stage of primary training with the use of crossfit equipment ensures the positive development and strengthening of the musculoskeletal system of cadets, the improvement of their muscular system. Under the influence of systematic crossfit classes, the VL increases, the circumferences of the chest and shoulders increase, the volume of the waist decreases, and body weight stabilizes. These circumstances have a positive effect on the work capacity of cadets, improve their physical health, improve their well-being and increase their work efficiency.
