Abstract

Background & Purpose: The aim of this study was to survey the validity of the modified Conconi running test for determining of the maximal lactate steady state in young male athletes.
Methodology: 11 young wrestler men were selected (Mean ± SD Age 19.01 ± 1.3 yrs., Height 176.64 ± 3.54 cm, BMI: 23.7 ± 4.0 kg/m2, VO2max: 51.08 ± 3.67 ml/kg/min) and incremental exercise tests in two sessions with an interval of 48 hours {1- accordance to conconi modified protocol (slope:1.5%, began speed: 3 km/h, increasing the speed of one Km per 60 sec) 2. criterion test: Increasing up MLSS }performed on a treadmill. The HRDP was determined by the S.Dmax model. Bland-Altman graphical model and Interclass Correlation Coefficient (ICC) statistical tests were used to evaluate the absolute agreement of the methods.
Results: The results indicated high agreement between HRDP and HR of the criterion method (HRMLSS) (±1.96; 95% CI= -2.4 to +7.7 b/min; ICC= 0.81). Moreover, high agreement was observed between speed at HRDP (SpeedHRDP) and speed of the criterion method (SpeedMLSS) (±1.96; 95% CI= -0.57 to +0.95 km/h; ICC= 0.83).
Conclusion: The HR and velocity at the deflection point determined by the modified Conconi running test could predict the HRMLSS and speedMLSS. It seems that this test could be a good alternative to more invasive method to determine the anaerobic threshold test as a simple, noninvasive short for the prescribed exercise intensity in athletes used.
