[The cost of energy and cardiovascular expenditure in basketball players during a game].

Energy expenditure was evaluated for 6 Basket players while exercising on a cyclergometer. Oxygen consumption (VO2), pulmonary ventilation (VE), heart rate (HR), respiratory quotient (QR) and other parameters were estimated at various levels of load (25 Watt each step of 3 minutes duration), till to submaximal load of 175 Watt. The same subjects participate to a regular Basket game and their heart rate was continuously stored on a tape recorder (Holter). Arterial blood pressure was also taken whenever possible (timeout, etc). From the laboratory and field data, estimates were made for the oxygen consumption together with energy cost of the game. This can be assume a net value of 0.1339 Kcal X Kg-1 X min-1.
