Evaluation of the influence of learning conditions at a military university of the humanitarian type on the physical development of students

Abstract

A comparative assessment of the physical development of students of two groups of 30 people (the first at the beginning of training, the second - after 2 years) was carried out at a military university. Anthropometric (body length and weight, chest circumference at rest, on inhalation and exhalation) and physimetric (hand strength, lung capacity (VC), heart rate (HR), systolic and diastolic pressure (SBP, DBP)) parameters were assessed . Calculated body mass index, index of functional changes. Daily energy expenditure was 3117.7±34.0 kcal, the energy value of the diet was 3081.1±75.1 kcal/day. Body weight at the beginning of training was lower by 2.7 kg (p=0.001), chest excursion by 4.9 cm (p=0.001), VC by 90.0 ml (p=0.01), heart rate less by 4, 6 beats/min (p=0.02), SBP over 4.8 per mm Hg. (p=0.01). According to individual data, more than one third of the persons of group No. 1 had hand strength in the range of 40-49 kg, in the main share - in the range from 50 to 55 kg, in a tenth part - in the range of more than 56-60 kg. In group 2, the proportion of persons with minimal hand strength differed by almost two times, and with the maximum - by 2.3 times. In group No. 1, in 16.6% of overweight individuals, BMI fluctuated in the range of 25.5÷27.7 units; in group No. 2 in 13.3% in the range of 25.02÷25.8 units. Growth and dynamics of body weight, muscle strength indicated an increase in active body weight and a decrease in the fat component. Organized life, nutrition, daily routine and the involvement of students in sports sections contribute to the development of physical qualities, increasing the adaptive capabilities of the body (the proportion of people with satisfactory adaptation is 4 times higher, functional stress is 1.6 times lower).
