As we have discussed list the end products of fast or anaero

As we have discussed, list the end products of fast or anaerobic glycol sis. Define EPOC and list four (4) possible causes of EPOC. Define the lactate threshold. List possible explanations for the lactate threshold.

Solution

Answers:

(50) Fast anaerobic glycolysis is referred to lactic acid fermentation which provides energy in the form of ATP during intense exercise. The end products of lactic acid fermentation is lactic acid and NAD⁺. The NAD⁺ so produced enters glycolysis to produce ATP.

(51) EPOC (Excess post-exercise oxygen consumption) can be defined as the measurable increased rate of oxygen consumption by the body due to intense exercise to meet the body\'s oxygen demand.

Causes of EPOC:

(a) Depletion of phosphocreatine and ATP.

(b) Depletion of glycogen

(c) Lactic acid accumulation

(d) Depletion of oxygen reserves in myoglobin

(52) The exercise intensity at which there is an exponential increase in the level of lactic acid in blood is referred to as lactate threshold.

The blood lactate level remains at normal level during resting phase. During intense exercise, there is a significant shift from aerobic to anaerobic energy production (Lactate fermentation) which results in a sharp increase in the blood lactate level, thus crossing the lactate threshold and an increased oxygen demand.
