Exercise machine application at classes with students with musculoskeletal system disorders

Most research papers on physical education of students note worse health, physical and functional condition of students. A solution to this problem would be to use new organizational forms of activity, the use of physical culture tools popular with the youth. Exercise machines of various designs are widely used in the recovery and support of physical condition. The use of exercise machines in the universities at classes with students of special medical group will significantly expand the range of means and methods of therapeutic physical culture and improve the recreational effectiveness of exercise. The health care effect of training on exercise machines is to improve the functional state of the musculoskeletal system. Restorative effect of exercise is achieved by their implementation with resistance. The level of power abilities of back, abdominal, shoulder girdle muscles is supported. The training class combines general developmental, breathing, and relaxation exercises. The main goal of treatment is to strengthen the back muscles and restore the symmetry of their structure. The axial load directly on the spine is not allowed. The aim of our work is to develop a technique of training on exercise machines in the training process of university students with musculoskeletal system disorders and an experimental confirmation of its effectiveness in the teaching experiment. Once a week the control group swam in the pool and once a week they played sports games. The experimental group worked in the pool and in the gym, once a week each. For training in the gym, we have developed an experimental technique. The duration of each power exercise was 35 seconds. The time of rest between the exercises was 85 seconds for two minute intervals between sets, 145 seconds for three minute intervals, etc. By the number of repetitions we used non-extreme regulated and repeated loads. The load value was average - the strain rate was 40 to 60% of the maximum. With the development of the functionality of the organism the load was 60% due to the number of repetitions which caused the greatest fatigue. When correcting the existing deformation and vertebral muscle tone imbalance the load was 40%. The intensity of the load was moderate (heart rate of 120-140 bpm). The load was chosen for each student individually. During the class we recorded the heart rate after the exercise and in the rest period. To assess the effectiveness of the experimental procedure we used methods of pedagogical testing of the physical condition of the students before and after the experiment (Harvard Step Test, spirometry, Stange sample, Genchi sample, dynamometry, tests of power, speed and power abilities). The effectiveness of exercise at the gym in the educational process of students with musculoskeletal system disorders is experimentally confirmed on the basis of significant differences of the physical condition of students of the control and experimental groups after its application.
