• Resumen

  • Left ventricular function was evaluated in 14 adolescents (13.1 ± 1 years) at maximal oxygen uptake and at peak Wingate anaerobic test by means of echocardiography. Significant (p < .05) differences between aerobic and Wingate test bouts were found for: cardiac output (15.5 ± 1.2 and 12.2 ± 1.1 L/min, respectively); left ventricular end-systolic pressure¿volume ratio (5.2 ± 0.8 and 6.0 ± 0.7, respectively); ejection fraction (72.2 ± 5.2 and 65.2 ± 5.1%, respectively); and mean arterial blood pressure (102.9 ± 10.8 and 111.1 ± 11.3 mmHg, respectively). Data suggest that left ventricular function at peak Wingate anaerobic test was markedly lower from that observed at peak aerobic exercise as a result of a higher afterload response
