Instrumental pedagogical technology of sports testing of students

Abstract

At the present stage of development of physical training, it is relevant to use instrumental methods of control and monitoring heart rate variability (НRV) in people involved in physical culture and sports. Purpose. To investigate and study the features of the manifestation of the parameters of heart rate variability (НRV) in students in response to the impact of physical activity of various volumes and directions. Research materials and methods. Using the system of sports testing "MedicalSoft", we analyzed the heart rate variability (HRV) in 70 young men aged 18.7±1.1 of the Medical University (Russia). We conducted the initial HRV study of students according to the standard protocol in a state of physiological rest (control indicators pNN50, SDNN, HF and LF, autonomic balance index LF / HF, VLF, TP (total spectrum power), SI (stress index). Then, we studied the HRV parameters after performing each motor test of various directions and load volume (test indicators). To assess the effect of the dynamic strength of the muscles of the lower extremities on HRV, we used the "long jump" test. To assess the effect of power loads, we used the "flexion and extension of the trunk" test in the supine position" and the test "pulling up from the hang on the bar". We assessed the motor qualities "dexterity" and "speed-strength endurance" using the "shuttle run 3x10 meters" test. We evaluated the motor quality "quickness" according to the results test "100 m run. Research results. The test values of all indicators of students according to the HRV protocol significantly differ from the role. In the motor tests "running 100 meters" and "pulling up from the hang on the crossbar" in young men, the predominance of sympathetic innervation and the central mechanisms of regulation of the cardiovascular system over the autonomous one, a decrease in the body's tolerance to physical activity and the development of a state of disadaptation were established. Conclusions. The instrumental method of sports testing of the state of vegetative regulation of the heart rate can be used in the pedagogical practice of physical education of students to reduce the risk of overstrain, disadaptation and the occurrence of a critical state of the body.
