Effect of 4-Week Physical Program on Musculoskeletal System Changes in Adolescent Sport Class Students with Focus on Ice Hockey

The purpose of the study was to identify musculoskeletal system changes in adolescent extraleague ice hockey players. The 4-week physical program was realized within lessons of physical and sport education. Methods: The monitored group consisted of 11 adolescent sports grammar school students in Nitra, Slovakia (aged: 17.27±0.5; body height: 175.96±1.2 cm and body weight: 77.23±3.5 kg) who were the extraleague hockey players of HK Nitra. To monitor their musculoskeletal system, we used standardized methods for physical and medical practice, such as Klein and Thomas modified by Mayer. Results: The students' physical and sport education programs had positive changes on their musculoskeletal system, both in the muscle system (Wtest=p<0.05) and in the area of posture Wtest= p<0.05). While comparing the level of the students' posture as the external manifestation of the functional muscle system, we stated that the difference, the improvement between the input (12.4) and the output (7.9) testing was significant with the value of p = 0.03 (Wtest=p<0.05). By applying the 4-week physical program, the pain in the cervical and lumbar spine in students was also eliminated.
