Effect of acute isostar sport drink on some of the cardio respiratory parameters of young soccer players in one bout of exhausting activity

The purpose of this study was the acute effect of Isostar Sport-drink on some of the Cardio-respiratory parameters in young soccer players a single bout of exhausting activity. Statistical sample of this study was 10 young soccer players who ‎were the players of Sepad Tehran Club with average age 17.10± 0.78, high 176.50± 4.85 cm, weight 67.46±5.69 kg and the body mass index 21.63±1.42 kg/m2 which have been voluntarily chosen. The subjects take a progressive protocol which has been simulated to run on a treadmill, and during the protocol, Gas Analyzer was used to measure physiological parameters including the VO2max, vo2, vco2, RER, VO2AT, VO2AT/VO2. Then, one week later, the subjects returned and drank a Isostar Sport drink, and executed the protocol. The results of this study showed metabolic parameters (VO2max, vo2, vco2, (RER), VO2AT, VO2AT/VO2) have ‎no significantly changed after consuming Isostar beverage. we can concluded that the use of Isostar beverage on one occasion, does not lead to a significant change in VO2max،vo2،vco2, (RER)، VO2AT، VO2AT/VO2 ratesand athletes should be wary to use this sport drink.
