Neuromuscular fatigue 2

The ability of the muscle membrane to conduct an action potential maybe related to fatigue in activities demanding a high frequency of stimulation.

• True

• False

The primary mechanical factor that related to fatigue is _____.

• cross-bridge cycling

• reflex drive

• transverse tubular system

• muscle sarcolemma

Excessive endurance training (overtraining) has been associated with symptoms such as reduced performance capacity and prolonged fatigue.

• True

• False

Based on energetic of contraction theory, fatigue is directly associated with a mismatch between the rate at which the muscle uses ATP and the rate at which ATP can be supplied.

• True

• False

Muscle fibers are recruited in the following order with increasing intensities of exercise:

• type I --> type IIa --> type IIx

• type I --> type IIx --> type IIa

• type IIa --> type IIx --> type I

• type IIx --> type IIa --> type I
