Abstract: 

The minimal running velocity at which the maximal oxygen uptake is elicited during an incremental test to exhaustion (vVO2 max) has been used to prescribe training for competitive middle and long-distance runners. The purpose of this study was to determine the relationship between velocity lactate turn point (vLTP) and vVo2 max in long-distance runners. For this reason 11 High- trained endurance runners were selected randomly from national team. The average of age, height and weight of the subjects were 24.36+1.1 years, 173.36±2.10 cm and 63.25+21 kg respectively. The first test was used to determine vVo2 max and Vo2 max (A continues run to exhaustion with the start velocity at 10 km/h-1 and the velocity increased 1 km/h-1 per minute). The second test was used to determine vLTP (start velocity was 10 km/h-l and velocity increased 1 km/h-1 per 4 minutes to reach lactate concentration over 5mmol). The average of V02max and vVo2 max of subjects was 58.54±2.8 ml. kg/min-1 19±0/29 km/h-1 respectively. The Pearson’s coefficient correlation and spss 12 software were used for analyzing data. The result showed that there is a positive moderate correlation between vLTP and vVO2 max (p=0.037, r=0.63). The study showed that vLTP may influence vVo2 max and it can help athletes to delay their lactate accumulation in higher velocity then they can have a higher v VO2 max. In the other hand, coaches can design the training in vVo2 max intensity to make a higher vLTP.
