Blood leukocyte and glutamine fluctuations after eccentric exercise.

abstract：:Increasing exercise intensities will induce an increase in glycolytic flux. High glycolytic activity is associated with reduced fat oxidation rates and increased accumulation of lactate. Both lactate and hydrogen ions have been shown to be directly related to the decreased fat oxidation rates. The aim of the present s...

abstract：:The oxygen uptake (VO2) attained during a constant speed 800-m pace trial on a treadmill is less than the maximal VO2 (VO2max) in male middle-distance runners with a high VO2max (i.e., > 65 ml x kg (-1) x min (-1)). We therefore investigated whether the VO2 attained was influenced by the pacing strategy adopted. Eight...
