7.7. ANNUAL DYNAMICS OF PHYSICAL FITNESS
When comparing the indicators recorded in different periods of the year, it should be noted that the clearest positive dynamics of changes in the studied indicators is for the period from September to May. For the summer months, stagnation in the indicators of physical fitness was typical, and in some cases there was a slight tendency to decrease them and was accompanied by an unreliable increase in the weight of the subjects.
It was of scientific interest to study the dynamics of changes in individual indicators of physical development of female students studying at a medical school located in a region with a high ambient temperature. During the three summer months - from May to September - body weight gains significantly exceed the gains that take place during the entire academic period - from September to May months. If we compare this circumstance with the facts obvious to residents of the southern regions of the country of residence, such as a large loss of body weight at high ambient temperature and a decrease in appetite caused by the same circumstance, then the fact of a significant increase in body weight in the summer months is obviously explained by a decrease in motor activity and, accordingly, a decrease in energy consumption during this period of the year. It should be noted that the increase in body weight in this case was not accompanied by an equally significant increase in body length and, therefore, it cannot be explained simply by the activation of growth processes during this period. Consequently, the increase in body weight is associated only with an imbalance between the arrival of energy and its consumption due to the general processes of vital activity and muscle performance. A decrease in muscle activity, even a slightly lower caloric intake, has the consequence of an increase in body weight.
The analysis of the dynamics of changes in the results of the physical status of female students of the medical school received during the pedagogical experiment revealed a change in speed indicators based on the results in the 100 m run, where significant changes were observed throughout the academic year. Thus, for female students of the first and second years of study in the period from September to January, the average improvement in results is small in absolute values (does not exceed 0.2 s), but statistically significant (p<0.01) In the autumn-winter-spring period, changes in achievements in the 100 m run are statistically significant (p<0.05). Thus, it follows that there is a statistically significant change in the time interval from September to May. If in spring the average achievement of first-year female students was 16.71 ±1.0 s, then in autumn the average result was 16.72± 1.1s. (0.99%) The difference was insignificant.
