The physiology of physical effort is based on diagnosing how physical activity, effort or sports affect the proportions or activity of a human body. A training programme or effort of the given group, e.g. boys training handball while studying in a lower secondary school, may consist in improving the health and functioning of a body and increasing the level of sports fitness.
The objective of the study was to assess the level of body fat of people training handball, depending on their level of training, physical fitness and age.
The study covered a group of 83 boys studying in the 1st, 2nd and 3rd grades of lower secondary school. The study applied the International Physical Fitness Test. It was also necessary to take body measurements necessary for calculating such indices as: Body Mass Index (BMI), Slenderness Index (SI), Rohrer’s Index (RI) and the Waist Hip Ratio (WHR). The assessment of body fat of the students was based on the measurements of skinfolds.
The best results in terms of BMI were demonstrated by 3rd grade students – 85.71% had correct body weight. In the measurement of waist size of the eldest students, the standard deviation was lowest, which demonstrates lower diversity of results among the boys from the 1st and 2nd grade. When measuring the skin folds, it was noted that the results were higher over age. The International Physical Fitness Test demonstrated that the eldest boys had better general results than the younger ones.
All the tested boys demonstrated a higher than average level of fitness. The level of physical fitness improves with age. However, for the purpose of obtaining more authoritative research results, more people should be tested.
