Young (10-14 years old) tennis players aerobic capacity

The object of the study: the object of this study is children aerobic capacity. The problem of the study: there are few studies to examine aerobic capacity of children of this young age and also playing tennis. So it is unknown if tennis training sessions create a sufficient stimulus to increase aerobic capacity. The aim of the study: to evaluate aerobic capacity measures of young (10-14 years old) tennis players in comparison with sedentary children of the same age. Objectives of the study: 1. To compare maximal aerobic capacity measures of two observed groups during the increasing running test. 2. To compare oxygen uptake kinetics of two observed groups during the 6 minute walking test. 3. To compare spirometry results of two observed groups. Methods of the study: 1. Measuring body composition and height; 2. Spirometry test; 3. Sequentially increasing load test to get data about maximal aerobic capacity measures; 4. 6 minutes walking test; 5. Monitoring respiration with Oxyconn Mobile during all the tests; 6. Mathematical statistics. Hypothesis: children who play tennis constantly have slightly better aerobic capacity parameters then sedentary children of the same age. Conclusions: 1. Young (10-14 yrs.) tennis players have increased aerobic capacity. They have higher aerobic power (VO2max) and ventilatory thresholds results compared to sedentary children. 2. Young (10-14 yrs.) tennis players and sedentary children of the same age have similar oxygen consumption kinetics results. 3. Young (10-14 yrs.) tennis players and sedentary children of the same age have similar spirometric characteristics
