Most PFK2 isoforms both generate and degrade F-2,6-bisP, which activa...

Metabolomics Application in Exercise Metabolism Research: A Review Study

Metabolomics, is a comprehensive measure of small metabolites (<1500 Da), which has attracted enormous attention in the last two decades. Metabolomics, in particular investigates unique biochemical fingerprints left behind by specific cellular processes, which represent the metabolic status. Exercise metabolism researchers have started to use this method since 2007. Metabolomics has been used t...

Metabolism in Exercise

Fat Metabolism during Exercise

2. As exercise progresses from low to moderate intensity, e.g., 25-65% VO2max, the rate of fatty acid mobilization from adipose tissue into blood plasma declines, whereas the rate of total fat oxidation increases due to a relatively large use of intramuscular triglycerides. Intramuscular triglycerides also account for the characteristic increase in fat oxidation as a result of habitual enduranc...

Exercise metabolism in runners.

The purpose of this study was to re-examine the commonly accepted association between high maximum oxygen uptake (VO2 max) values and the characteristics of metabolic adaptation to endurance training. The metabolic responses of 9 active males and 8 endurance trained females were observed during one hour of treadmill running at two speeds. One speed was common to both groups (3.58 m s-1. Test 1)...
