Lactic threshold vs ventilatory threshold during a ramp test on a cycle ergometer

摘要: Objective. The purpose of this investigation was to study the relationship between lactate (LT) and ventilatory threshold (VT) during a ramp protocol in cycle ergometry. Participants. Thirty nine trained male subjects were selected as subjects. Experimental design. All performed maximal ergometric test on ergometer consisting (increases 25 W.min -1 ). anaerobic (AT) determined using both gas analysis measurement (LT). data related VT LT expressed work rate (W), VO 2 (ml.kg .min ) heart (bpm) mean standard deviation. Lactate compared Student's t-test for paired data. Correlation coefficients variables also calculated. Statistical significance accepted at 5% level. Results. Results showed significant differences (p<0.05) values when either (bpm), or (ml. kg Conclusions. It concluded that occur different exercise intensities ergometer.
