Abstract:
There have been very few reports on the relationship between stroke volume and heart rate in the physically loaded children. Continuous records had been made onthe changes in SV and HR during the graded exercise in 16 eleven--year--old pupils(as subjects) of a youngster's sports school and 27 matched ordinary pupils (ascontrols) by the electrical impedance method. The results are as follows: (1) Thevalues of SV and HR in the subjects and controls present significant difference whenHR is 110--140 beats/min during exercise and 90--130 beats/min during recovery;(2) CO increases with the increasing HR when HR is 110--190 beats/min; (3) Thepeak SV appears in between HR 100--120 beats/min. Therefore, we consider that itis advanta geous to the development of function of the children's hearts by combi-ning the moderate continuous exercise with less load in longer time and submaximalload with short interval.
