Abstract
In order to compare the cardiorespiratory responses in ventilatory anaerobic threshold (VAT) in relation to gender, age and published data, were evaluated 289 adoles- cents of both sexes, between 10 and 14 years, who underwent a cardiopulmonary test using a ramp protocol on treadmill. The VAT was identified by the methods of the V-slope and/or ventilatory equivalent of oxygen. The results showed that oxygen consumption (VO2 VAT) absolute was higher in boys at 13 and 14 years. The VO2 VAT relative to body weight was different only between genders aged 14 years old, and being higher in boys than girls. We conclude that there is loss of aerobic fitness in adolescents of both sexes from the age of 12. The VO2 VAT was lower when compared with the literature.
