Opis:
The goal of the thesis was to identify and then compare the incidence of muscle imbalance at 3rd grade students in the academic years 2012/2013 and 2013/2014 at EF CPU in Nitra. The object of our monitoring were 78 students in decimal age from 20.21 to 27.58 years. We analyze the overall incidence of muscle imbalance in the two academic years, the frequency of shortened muscles, weakened muscle and movement stereotypies disorder. At the same time we compare identical characteristics among all female students and among male students as well. We examined the muscle imbalance according to method of Janda (1982) modified by Thurzová (1992) for the purpose of physical education. Based on the measurements, we discovered a high occurrence of overall muscle imbalance at every tested subject in both academic periods. We noticed that the occurrence of shortening in shortened muscles was the highest in the first period in m. rectus femoris and in 78.4 % of subjects and next period at m. quadratus lumborum in 82.4 % of subjects. The frequency of muscle weakened was the highest in both periods the extensors of hip joint in 83 % of subjects first period, 85.3 % of subjects of the second period. When movement stereotypies we observed a high incidence of breaches of movement stereotypies in extension in hip joint in both academic years and 83% (2012/2013) and 82.4 % (2013/2014) subjects. Based on the identified results, we can deduce that not only in individuals that lead hypokinetic way of life but also for students who are regularly engaged locomotor activity but no emphasis on thorough compensation tends to develop muscle imbalances.

Opis:
Introduction: The research was aimed at obtaining and extending the findings of the functional state of musculoskeletal system of the research sample of volleyball players, and also the possibilities of influencing the balance exercises in the sports training of athletes. Material and Methods: The research sample consisted of 12 volleyball players (girls) from the Stara Lubovna Volleyball Club. The first measurement was carried out in September 2015. The average decimal age of the volleyball players was 15.76±0.88 years. In the final measurement, which was made after three months in January 2016 and after the application of a targeted program of balance exercises, the average decimal age of the group was 16.09±0.88 years. Results: The initial measurement of the players found a high percentage of functional muscle disorders and the most risky muscles and muscle groups that tend to shorten and weaken in the analyzed subjects. Based on the above, a targeted compensation program of balancing exercises was developed. A significant decrease of the incidence of measured functional muscle disorders to p<0.01 of shortened flexors of the knee, musculus rectus femoris, of weakened abductors of hip joint, deep neck flexors, lower fixators of spatulas and broken motor stereotypes - one leg stand and push up was observed after the inclusion of experimental factor into the training plans actively for a three-month period. We noted a decrease in shortened musculus triceps surae, musculus quadratus lumborum a musculus iliopsoas, of weakened abdominal muscles and of sitting down stereotype on the significance level of p<0.05. Conclusion: Significant conclusions may be drawn from the acquired statistical data: the inclusion of appropriate and regular balance exercises in the training process of young athletes has a positive impact on reducing or eliminating muscle functional disorders of the musculoskeletal system in its individual components - shortened muscles, weakened muscles and impaired movement patterns.

Opis:
Introduction: Isometric and isokinetic dynamometers are mainly used for assessment of strength and endurance of core muscles. However, muscle power represents a more appropriate variable for evaluating of athlete performance that involve dynamic movements of the trunk. This study estimates test-retest reliability of trunk rotational power and velocity over a 1-week interval using the FiTRO Torso Isoinertial Dynamometer. Material and Methods: A group of 32 physically active men performed 5 trunk rotations to each side while seated with a barbell of 1 kg or 20 kg placed on their shoulders. Results: Results showed that assessment of peak and mean velocity in the acceleration phase of trunk rotations with 1 kg provides reliable results (ICC = 0.94 and 0.92 respectively, SEM = 7.0% and 7.3% respectively). However, peak and mean values of velocity and power obtained during trunk rotations with a weight of 20 kg should be interpreted with caution (ICC < 0.80, SEM > 10%). Conclusions: Such an assessment of trunk rotational power and velocity can be used in practice, however with a limitation of performing trunk rotations in a seated position and using lower loads.
