Question

Explain any 2 physiological factors, help in determining endurance.

Answer 1

The capacity to maintain an activity for prolonged periods of time is known as endurance, and it typically relates to aerobic capacity. The ability to withstand muscle fatigue and explain how a specific contraction can be maintained, usually expressed in terms of repetitions, is the purest definition of endurance. The following physiological parameters can be used to determine endurance, which is another important aspect of physical fitness.

1. Lactic acid tolerance: Lactic acid is produced by muscles during vigorous activity. It is a metabolic byproduct that has no bearing on how well an exercise session goes. It results in post-exercise muscular soreness and muscle fatigue. Anaerobic capacity is largely determined by the ability to withstand higher lactic acid concentrations, which can aid in enhancing endurance performance.
2. Movement economy: Economical movements are necessary for notable endurance performance. A runner can run over extended periods of time at a certain speed with less energy. An effective strategy can conserve energy in endurance sports.
3. Muscle composition: The slow twitch fibers are best used for aerobic or endurance exercises. They are well-suited for endurance exercises since they can exert a little amount of force for prolonged periods of time. In fact, it has been observed that elite marathoners have over 90% slow twitch fibers in their leg muscles. Slow twitch fiber proportions are controlled by genetics.
