Chapter 3: bioenergetics of exercise and training Flashcards
this begins at approx. 50-60% of VO2max
Lactate threshold
this occurs when the concentration of blood lactate reaches 4 mmol/l
onset of blood lactate accumulation (OBLA)
Total energy yield from the oxidation of one glucose molecule: (slow glycolysis) substrate level phosphorylation
4
Total energy yield from the oxidation of one glucose molecule: (slow glycolysis) oxidative phosphorylation
6
Total energy yield from the oxidation of one glucose molecule: (Krebs cycle) substrate-level phosphorylation
2
Total energy yield from the oxidation of one glucose molecule: (Krebs cycle) oxidative phosphorylation
24
Total energy yield from the oxidation of one glucose molecule: (Krebs cycle) via GTP
4
Total energy yield from the oxidation of one glucose molecule: (slow glycolysis, Krebs cycle) total
40 (38 if starting from blood glucose)
Primary energy system used (time, intensity): 0-6s, extremely high
phosphagen
Primary energy system used (time, intensity): 6-30s, very high
phosphagen and fast glycolysis
Primary energy system used (time, intensity): 30s-2m, high
fast glycolysis
Primary energy system used (time, intensity): 2-3m, moderate
fast glycolysis, and oxidative system
Primary energy system used (time, intensity): >3min, low
oxidative system
This has the greatest effect on EPOC
intensity
Interval training to train specific energy systems (%of maximum power, typical exercise type, range of work-rest period ratios): phosphagen
90-100%
5-10s
