Maughan & Gleeson: The Biochemical Basis of Sports Performance
Chapter 04
- What is the net ATP yield of anaerobic glycolysis if the substrate is glycogen? Why is this different if the substrate is glucose taken up from the blood?
- If 10 mmoles of lactic acid were added to one litre of water the pH would change from pH 7 to pH 2. Why does a smaller pH change occur when the blood lactic acid concentration rises to 10 mmoles/litre during high intensity exercise?
- Explain why bicarbonate ingestion can influence performance in middle distance running.
- List the possible causes of fatigue during a 1500 m race.
- What factors influence the rate of muscle glycogen breakdown during exercise?
- Why is fat not an important energy source for middle distance running?
