Abstract

The energetic cost and cardiovascular load of a regular basket ball game have been investigated on 6 semiprofessional players. A correlation between heart rate (HR) and arterial blood pressure (PA) obtained during a field game, and the corresponding parameters while the same subjects exercised on cyclergometer has been done. During field game HR goes up to 148 +/- 2 beats/min. (= 73 of HRmax) whereas systolic PA rise up to 148 +/- 4 mmHg. No statistical difference has been encountered between the first and the second time of the game. The results obtained indicate that the net energy demand for the basket ball game is 10.23 Kcal/min, corresponding to 0.1339 Kcal/Kg/min. The thermic load is elevated reaching a value of 4.98 Kcal/m/min, equivalent to 8.14 Kcal/Kg for the whole game duration. Calculated body weight loss corresponds top 1176 g/game (velocity of weight loss: 18.39 g/min) attributable in part to water (16,76 g/min) and in part to substrate loss (1.63 g/min). Verf.-Referat
