VITAL CAPACITY OF THE LUNGS OF TRAMPOLINE GYMNASTS AGED 10-13

Abstract

Vital capacity (VC) tests are an important tool in assessing the functioning of the respiratory system. Low levels of vital capacity can indicate health problems such as asthma, chronic obstructive pulmonary disease, and other respiratory conditions. The volume of VC depends on many factors, especially the strength of the respiratory muscles, body and chest structure, lung and chest compliance, airway patency, gender, environmental factors, and physical activity. The aim of this study is to determine the level of vital capacity (VC) in girls and boys aged 10-13 who practice trampoline jumping, and to compare the results with reference values for a given gender and age category. The research was conducted among 100 trampoline jumpers (including 57 girls and 43 boys) aged 10-13. As part of the research, spirometric measurement was performed using the portable EasyOne model 2001 spirometer. The obtained results were then compared to reference values calculated on the basis of a study by the European Respiratory Society. The average level of vital capacity in the girls aged 10 was 2.2 liters, in 11-year-olds - 2.45 l, in 12-year-olds 2.54 l, and in 13-year-olds it was 3.02 l. The average level of vital capacity of the examined boys aged 10 was 2.36 l, in 11-year-olds 2.56 l, in 12-year-olds 2.89 l, and in 13-year-olds 3.33 l. These research results indicate that trampoline jumpers show a VC value within the reference values (between the LLN and ULN values). The girls stand out with higher percentage of predicted values for VC at the age of 11 (95.26%) and 13 (100.34%), in comparison with boys at the age of 10 (96.38%) and 12 (96.23%).
