RESULTS OF EXAMINATIONS (69 BOYS , AGE 14 YEARS)
Summary Results of functional exaninations are presented, which were obtained at graduated loading on a bicycle ergometer , in 69 boys , age 14 years. The boys wre divided into groups , containing untrained subjects and sports gymnastics.
Significant differences were found between the boys trained in light athletics , swimming and the untrained boys ( the control-group) , as far as the functional response is concerned.
According to several indices , as for instance PWC 170, maximum oxygen uptake and maximum minute ventilation as well as the heart rate course at submaximal loads , an increasing fitness has been found in boys practising different sports activities. The increase depended on the type of the motional activities: the fitness was only slightly higher in subjects practising sports gymnastics, it was higher in light athletes and highest in swimmers. In comparison whit an average population , the high physical fitness reached in individual indices in 14-year-old boys values , found usually in a youth population of higher age , or even in an adult population. Conditions , originating the training adaptation are discussed.
Phisical fitness of a subject may be well characterized by the value of PWC 170 and by the value of the constant calculated from three heart rate values , obtained at three submaximal loads. Similary , the fitness may be judged of on basis of a comparison of the dependence of the heart rate or minute ventilation on the oxygen uptake , at graduated load.
