[Echocardiographic values of healthy children in relation to ergometric performance (author's transl)].

The results of echocardiographic and ergometric studies on 22 children are presented. These children were involved in a daily lesson of gymnastics, swimming or rollerskating of one hour duration. Depending on the exhaustion during ergometry, the maximal parameters showed the same results as known from the literature. There were also no different results of echocardiographic values compared with weight or body surface related data of normal subjects. Normal values for echocardiographic data are presented and discussed with parameters of the maximal performance of the children. From that it is concluded that these sport activities do not influence the dimensions of the heart and its function because of the low intensity and short duration of the additional training lessons in contrast to the high spontaneous motoric activities of children.
