Background and Study Aim: The incessant technological progress and negative effects of environmental pollution which are felt more and more by an ordinary human being are the phenomena which have impact on the development of civilisation diseases. Judo by the authors of many publications is recommended as the optimal sport life for all. The aim of the study was the knowledge about overall physical fitness of school youth who train judo and who do not practice any sport.
Materials and Methods: The study group consisted of 44 boys 11-12 years old, including 22 persons who train judo (three times a week for 90 minutes each training session) and 22 boys who do not practice any sport. The Test of Physical Fitness (development by the International Committee on the Standardisation of Physical Fitness Test) was used in the study. Test results based on the score tables and were subjected to statistical calculations. An arithmetic mean, standard deviation, skewness, kurtosis and Student's t-test were calculated for independent samples.
Results: Boys who train judo do not exceed on the level statistically significant boys who do not practice any sport only in 3 tests: a run over a distance of 50 meters; a run over a distance of 600 meters (boys 11 years old, and 800 meters 12 years old); handgrip strength. The difference in results of the other 5 tests is significant (p<0.0005) on the plus side of judokas. Also, the average sum of the difference scors (judokas 517.45, boys who do not practice sport 452.91) is statistically significant (p<0.01). Among young judokas individual differences are much smaller. In the group of boys who do not practice sport three (13.64%) revealed very low levels of overall physical fitness (sum of scores 316 to 318).
Conclusion: Assuming that before the start of judo training both groups of boys did not differ significantly in terms of overall physical fitness and empirical data suggest that most stimulate these exercises: power and muscle strength, agility, flexibility. These features are cited as very important for the motor safety and the health positive of man throughout his life.
