The effect of crossfit engagement on the body mass of mature men

Actuality. CrossFit was developed as a universal method capable of increasing the overall functionality of the body as soon as possible. Due to its simplicity, accessibility and real effectiveness, this functional training has earned worldwide popularity among different population groups. CrossFit circuit training uses cyclical exercises (cardio), exercises with your own weight and with weights. A large selection of basic exercises allows you to make interesting complexes (WOD) depending on the place and the equipment that is available. CrossFit exercises involve large muscle groups, so regular sessions, even if you only work with your own body weight, can soon significantly improve your overall physical condition and pull the body.. Despite the large number of studies carried out in recent years by domestic and foreign authors, regarding the use of various means of improving fitness and recreation in the process of classes with persons of mature age, issues related to the use and evaluation of the effectiveness of various forms and means of CrossFit training for mature men remain without sufficient attention. Currently, the commercialization of the field of sports and health services has contributed to the appearance of a wide variety of author's programs, which are often very difficult to evaluate due to the lack of information about their scientific basis. The study of this issue is especially relevant in the organization of improving fitness classes using CrossFit for mature men. Purpose of the research - theoretical substantiation and development of the methodology of health classes with CrossFit elements for men aged 40-49. Methods of research: analysis, summarization of materials; anthropometry; dynamometry; cardiointervalometry method; pedagogical testing; pedagogical experiment; mathematical and statistical methods. The duration of the developed program of the cycle of improving fitness classes with elements of CrossFit for mature men was one calendar year. According to the program, men practiced 3 times a week, the duration of the classes was 90 minutes. The program included fitness classes with CrossFit elements, aimed at increasing the aerobic capacity of the body, the level of general and special physical preparadness, technical mastery of performing CrossFit exercises, functional state, normalization of body weight. Also, the program included control of physical state, consisting of assessment of general and specific physical preparedness, functional state. At the end of each month, the functional state was examined. Four times a year, after every three months of improving health classes, an assessment of physical preparadness was conducted, which included testing of general and special physical preparadness and evaluation of the obtained test results using developed evaluation scales taking into consideration the age of men. In the program of the cycle of health classes with elements of CrossFit for men aged 40-49 years, the emphasis was more on improving the functional state of those who engage in. During which CrossFit elements were used and combined with other physical exercises (aerobic and anaerobic, aimed at developing strength, agility, speed, coordination, general endurance). With the purpose to find out the effectiveness of the developed program of improving health classes with CrossFit elements, studies were conducted aimed at determining anthropometric indicators, physical indicators of preparadness and functional state of mature men (aged 40-49), representatives of experimental and control groups. The distribution of participants was carried out by random distribution, as the respondents had the same initial data on the health state, physical preparedness and experience of classes. 60 men aged 40-49 were involved in the developed cycle of health-oriented programs with CrossFit elements for persons of mature age, who made up the experimental and control groups, including the same number of people (n=30). Pedagogical experiment lasted for one year. The men who participated in the testing provided medical certificates stating that they are in good health and can attend health-oriented classes, and have no contraindications to physical activity. Findings and results. As the pedagogical experiment showed, these classes had a positive effect on body weight and body mass index indicators. Before the pedagogical experiment, in both research groups there were equally overweight men whose BMI was in the range of 25.0 c.u. to 29.9 c.u. and obesity of the first degree, their BMI was equal to 30 - 34 c.u.figureFig. 1. Distribution of mature men with normal and overweight body weight before and after the pedagogical experimentAfter the pedagogical experiment, the percentage ratio changed (Fig. 1). In the experimental group, 63.3% of the participants were already of normal weight. The number of men with obesity decreased from 23.3 to 3.3%. Obviously, the share of those who exercise remained overweight - 33.3%. But if we pay attention to the fact that the classes were not aimed at reducing body weight, and the normalization of weight depends not only on motor activity, but on the whole complex - quality, quantity, nutrition, drinking regime, taking pharmaceuticals, etc., then the positive effect of the developed complex of health-improving class with CrossFit elements is obvious. In the control group, no positive changes were noted. On the contrary, after the experiment, the percentage of men with obesity of the first degree increased slightly. Conclusions and recommendations. As a result of our research, we came to the conclusion that CrossFit classes have a positive effect on the physical state of mature men, directly on the normalization of body weight. After all, CrossFit is a high-intensity fitness program that combines elements of strength training, cardiovascular exercises and functional movements. Further studies will be aimed at investigating the impact of CrossFit classes on the psycho-physiological indicators of mature men.
