Physical health of schoolchildren aged 14-15 years old under the influence of differentiated education

Abstract

Purpose:to determine the dynamics of indicators of schoolchildren physical health under the influence of a multilevel system of differentiated education. Material:The study involved schoolchildren (n = 148, age 14-15 years). Two control groups and two experimental groups were formed. Quantitative assessment of physical health was carried out according to 5 indices. Results:a low level of physical health of schoolchildren is established. The influence of the means of a multilevel system of differentiated education on the individual level of physical health of schoolchildren is determined.The most susceptible systems of the organism are determined to influence the differentiated training. An improvement in the adaptive capacity of the cardiovascular system during the recovery period after standard physical activity was revealed. Conclusions:The marked decrease in the heart rate at rest and blood pressure is evidence of a better state of adaptation mechanisms. A significant increase in the vital capacity of the lungs and the delay in breathing testifies to the improvement of the functional capabilities of the respiratory system and the body's resistance to hypoxic phenomena. Improvement in the development of strength, speed, speed endurance of the muscles of the back and abdominal press indicates an increase in the specific intensity of the performed work.

The Application of the Index Method to Assess the Condition of Armwrestling Athletes with Different Levels of Sports Mastery

“…The range of indices reflecting physical fitness and adaptive capacity was applied to assess the dynamics of physical health under the influence of a multi-level system of differentiated education (Masliak & Mameshina, 2018). Krivoruchko, Masliak, Bala, Skripka and Honcharenko (2018) applied the physical development indices as a criterion for the effectiveness of training in cheerleading.…”

Efficiency Eight Weeks Program of CrossFit Exercises on the Level of Physical Fitness of Algerian High School Students

“…The above is confirmed by the data of (Adel et al, 2019;Mokhtar et al, 2019;Saddek et al, 2020), according to which it was found that during physical exertion, muscle hypertrophy occurs as a result of adaptive-trophic influence (Mukund & Subramaniam, 2020;Teplov, 1982), which is characterized by an increase in thickness and denser packaging of contractile elements of muscle fiber (Haun et al, 2019;Narici et al, 1996). Thus, studies (Annesi, Westcott, Faigenbaum, & Unruh, 2005;Belkadi et al, 2019;Krivoruchko et al, 2018;I. P. Masliak & Mameshina, 2018) indicate that the introduction of functional exercises in the main part of the lesson contributed to a significant improvement in strength abilities of high school students.…”

“…To date, there is a problem of decline level of physical fitness, and as a consequence of health student youth. A number of leading experts (Harold W. Kohl, Cook, Environment, Board, & Medicine, 2013;Kaur, Singh, Arya, & Mittal, 2020;Mameshina, 2019;I. P. Masliak & Mameshina, 2018;Petrova & Bala, 2020) note that according to statistics, almost 60% high school children have health problems and low levels of physical fitness.…”

“…A number of scientists pay considerable attention to the issue optimization of the content of physical education lessons (I. Masliak, Krivoruchko, Bala, Horchaniuk, & Korchevska, 2019;I. P. Masliak & Mameshina, 2018;Petrova, 2021;Varea et al, 2021;Voloshina et al, 2018).…”
