Abstract

We comparatively evaluated metabolic equivalent (MET), percentage of maximal O-2, uptake (VO(2)max), anaerobic threshold (AT) and respiratory compensation point (RCP) parameters to find effective discrimination of exercise intensity levels in young males. Total of 40 subjects were performed an incremental exercise test (15 W/min) until to exhaustion using a cycle ergometer. Ventilatory and pulmonary gas exchange responses were measured breath-by -breath using metabolic and respiratory gas analyser systems. AT and RCP was estimated using V-slope method and ventilatory equivalent for CO2 output, respectively. O-2 uptake at AT, RCP and maximal exercise values were obtained and subsequently converted to MET (3.5 ml/min/kg). Anova test was used to analyse the significance of data. MET values at the AT associated with moderate intensity (n-6, 15%) heavy intensity (n=19, 47.5%) very heavy intensity (n=14, 35%) severe exercise (n=1, 2.5%) intensity. MET values RCP associated with heavy intensity (n=10, 25%) very heavy intensity (n=13, 32.5%) severe exercise (n=17, 42.5%) intensity. AT and RCP could be favour in adjustment of moderate and heavy exercise intensities. However, MET application for exercise intensity standardisation may comprise many questions. Thus investigators or clinicians may consider AT or RCP before taking important decision for health problems.
