Morphological status of students with different level of motor activity

A study of the effect of motor activity on the health condition of students that generalizes peculiarities of the morphological status and of physical development on the whole, permits to identify mechanisms controlling health factors. Aim. Determination of the peculiarities of the dynamics of morphological status of students with different levels of motor activity in the period of study at aninstitution of higher education (IHE). Materials and Methods. A prospective study of physical health of 630 students of 17-22 years of age in the period from 2010 to 2018. In students, the body length, body mass, chest circumference and other parameters were measured and the somatotype was determined every year in the period of study at anIHE (5 years). Results. It was found that in the period of study at anIHE, growth processes continued only in 51.9% of examined boys and gradually terminated at 21-22 years of age, and in 36.9 % of girls with termination at 21-22 years. In most students increment of the body mass and chest circumference was recorded, there were also found boys and girls with these parameters remaining unchanged during period of study at anIHE, and in some cases their decline was found. The increment of the body mass and chest circumference was demonstrated to slow down with termination of growth processes, but did not stop altogether which resulted in increase in the amount of students with excessive weight. This was also facilitated by reduction of the level of motor activity in senior years when physical culture classes are no longer included into the curriculum. The dependence of growth processes in boys and girls at the age of 17-22 years on the level of motor activity was revealed that influenced the speed and direction of increment of the total dimensions of the body and the type of body-build. According to our data, the majority of boys support a high level of motor activity to buildup the body mass, and girls lead an active way of life to decrease the body mass and to keep it on the optimal level.
