[Effect of physical training on growth and total cardiovascular and respiratory capacity in pupils from schools with different physical training programs].
OBJECTIVE
Influence of physical exercise on psychomotor growth of children is well known. In present study we tried to evaluate influence of two different physical training programs carried out in schools, on parameters of cardiovascular and respiratory system. In addition we tried to evaluate the possible influence of diet on children growth.


METHODS
Children from two schools were studied. Group I: 56 children (aged 10-12) from swimmers classes of the School of Sport Championship, who participated in 8 hours/week of physical exercises in addition to 10 hours/week of swimming exercises. Group II: 28 children (aged 10-12) from standard school, who participated in 3 hours/week of physical exercises. In both groups medical examination, spirometry, blood pressure and heart rate measurement, and diet analysis were performed at baseline and after maximal physical extortion.


CONCLUSIONS
1. Spirometry analysis showed statistical differences between the groups, which were impaired in children from school with standard physical training program. 2. We observed worse adaptation to physical exercise of cardiovascular and respiratory system in from school with standard physical training program, as compared to children from group I. 3. No statistical differences in nutrition were shown between the groups. 4. Vitamins, iron and magnesium seem to have good influence on respiratory system adaptation to physical exercise. 5. In general, we observed better total capacity of cardiovascular and respiratory system in connected with better interest in correct nutrition in group I as compared to group II.
