Abstract
This case study was aimed to study and establish the physiological variables caused by incremental endurance training of one sub-athletic male subject. It was designed to test the lactate threshold [LT], economy and maximal oxygen uptake (VO2max.) throughout two distinct parts of incremental endurance exercise using cycling ergometer. in contrast to the main hypothesis that was suggesting; the lactate threshold, the point of sudden rise in blood (systemic) lactate during incremental endurance exercise will have a fatiguing effect on performance and would not allow researcher to ascertaining a true VO2 max. However, the main results indicated lactate threshold [LT] taken place at work rate of 120 (w) represents 66.5% of maximum subject’s heart rate, obviously it did not affect the true VO2 max. result. So, a combination of factors may explain the variation of lactate threshold. Or rather, that lactate does accumulate as [LT] has variable effects on the outcome of subject’s endurance performance. That is to say, the uneconomical increase in power expenditure (economy), in addition to other metabolic determinants.
