ABSTRACT
The influence of physical activity of varying intensity and hypodynamia on the morphological indices parameters of the internal organs of rats in the experiment was investigated. Animals were subjected to the forced swim test by Porsolt of varying duration and to immobilization. The intense exercise, as well as long-term lack of exercise, were reveled to lead to the pronounced structural defects in the internal organs, while moderate exercise can be considered as the most favorable.

There was studied the physical development of 4550 schoolchildren of the city of Ufa at the age from 8 to 16 years. Almost a third of the students was noted to have disharmonious physical development. The proportion of children with excess of body weight exceeds the proportion of underweight children in 2 times. Modern schoolchildren of middle and senior age groups were established to have higher indices of height and weight in comparison with peers at the end of twentieth century, and in younger schoolchildren the indices are higher than in their peers in 2004.
