Dynamic control of load in special medical group students during PE activities

Aim. The article aims to evaluate the effectiveness of dynamic control of the workload during PE activities in special medical group students (SMG) using heart rate (HR) monitors. Materials and methods. The research involved 30 students with chronic pathology of the organs of vision, respiratory, cardiovascular, musculoskeletal, nervous and genitourinary systems. Control (CG) and experimental groups (EG) were formed of 15 people each. Before the beginning of the research, the intensity of physical activity was selected individually for each girl. During the training session, the load level in the control group was selected by the results of operational control, while in the experimental group it was chosen by means of dynamic control. The effectiveness of dynamic control was established by the comparative analysis of indicators of functional abilities, physical development and physical fitness of students. Results. During the research process, the average value of the chest circumference increased by 2.7% in CG and by 4.8% in EG, indicating an improvement in respiratory function. Despite the absence of statistically significant differences in this indicator, it should be noted that the chest circumference increased more in the experimental group. In the experimental group, a greater increase was noted in other indicators of the respiratory system. During physical activity, the average heart rate decreased by 4.8% and 7.1%, SBP by 7.7% and 11.1%, DBP by 6.2% and 6.3% in CG and EG, respectively, indicating an improvement in the cardiovascular system. SBP indicators were significantly lower in the experimental group. For other indicators significant differences were not revealed but it should be noted that in the experimental group the decrease was more significant. The increase in physical fitness in female students of both groups was registered in all eight indicators. The most significant increase (P<0.01) was noted in exercises for general and special endurance. In the experimental group, the increase was from 8 to 77 %, in the control group, from 4.6 to 52%. Conclusion. Dynamic control of training load using heart rate data obtained with heart rate monitors provides a more significant increase in physical fitness and body functions of SMG students, improves the efficiency of physical education management, provides an individual approach to the load control, as well as feedback during the training session and the possibility of choosing physical education methods. © 2020 South Ural State University - Institute of Sport, Tourism and Service.
