Comparison Ventilation Threshold And Heart Rate Deflection Point In Fast And Standard Treadmill Test Protocol

The purpose of the study was to compare two methods for determination anaerobic threshold from two different treadmill protocols. Forty-eight Croatian runners of national rank participated in the study (10 sprinters, 15 400m runners, 10 middle distance runners and 13 long distance runners) with a mean age of 21.7 ± 5.1 years performed two graded maximal exercise test on a treadmill, Standard ramp treadmill test protocol (TSR - speed increments of 1 km/h every 30 seconds) and Fast ramp treadmill test protocol (TFR - speed increments of 1 km/h every 60 seconds) to determine and compare parameters at peak values and at HRDP and VT. There were no significant differences between peak values at mean VO2 (4.48 vs 4.44 L/min), weight related VO2 (RVO2 - 62.52 vs 62.04 mL/kg/min), pulmonary ventilation (VE – 163.09 vs 161.29 L/min) and heart rate (192.35 vs 194.44 beats/min), that were measured in both protocol (TFR and TSR). Significant differences were found between running speed at anaerobic thresholds (vAnT) achieved in two different protocols, independent which methods for determination AnT were used (vAnT - 16.01 vs 14.94 km/h in VT methods and vAnT -16.46 vs 14.95 km/h in HRDP methods, respectively). Linear regression analysis revealed a correlation of 0.86 (p < 0.01) in TFR and 0.77 in TSR (p < 0.01) protocols between RVO2 measured at VT and RVO2 measured at HRDP, so the present study indicates that the point of deflection from linearity of heart rate (HRDP) may be an accurate predictor of VT for VO2 and HR in runners with predominantly aerobic or anaerobic energy contribution independently of used protocol. In the same time, we conclude that RQmax, achieved running speed and running speed at anaerobic thresholds are protocol dependent values
