| Popis | Increased heart rate and decreased baroreflex sensitivity are correlated with higher cardiovascular mortality and morbidity. Heart rate can be decreased by physical training, evaluation of the changes of baroreflex were the aim of the present study. It is concluded that a 1-year physical training decreased heart rate in boys and did not change of BRS and BRSf in adolescents of either sex. Significant correlation of pulse interval and systolic blood pressure in the first and the second measurement reveals their individual characteristic. On the other hand similar correlation was not found neither for BRS nor for BRSf. The prolongation of a mean pulse interval in boys group may be the first signal, which initiates the reconstruction period to sports heart. This is a general view on the regular physical training. |
