|
Exercise intensity |
The higher the exercise intensity, the greater the demand for energy (ATP) and the faster OBLA occurs because when glycogen is broken down anaerobically into pyruvic acid, lactic acid is formed |
|
|
Muscle fibre type |
Slow twitch fibres produce less lactate than fast twitch fibres. When slow twitch fibres use glycogen as a fuel, due to the presence of oxygen, the glycogen can be broken down much more effectively and with little lactate production |
|
|
Rate of blood lactate removal |
If the rate of lactate removal is lower than the rate of lactate production, lactate will start to accumulate in the blood until OBLA is reached. |
|
|
The respiratory exchange ratio |
When the ratio is closer to 1.0 glycogen becomes the preferred fuel and there is a greater chance of the accumulation of lactate. |
|
|
Fitness of the performer |
A person who trains regularly will be in a better position to delay OBLA, as adaptations occur to trained muscles . Increased numbers of mitochondria and myoglobin, together with an increase in capillary density, improve the capacity for aerobic respiration and therefore avoid the use of the anaerobic glycolytic system |
