Muscle Recovery and Fiber Characteristics

These flashcards cover key concepts related to muscle recovery, fiber types, and muscle conditions based on the lecture notes.

What causes muscle fatigue according to the notes?

Muscles don’t perform at the required level due to fatigue.

What is required to restore ATP levels in muscles?

A certain amount of recovery time is needed to restore ATP levels.

What are the two types of muscle fibers mentioned?

Fast fibers and slow fibers.

What is one characteristic of fast muscle fibers?

Fast fibers have a larger diameter and reach peak tension quickly.

How do slow fibers differ from fast fibers in terms of endurance?

Slow fibers can sustain contractions for longer periods.

What leads to muscle atrophy?

Lack of nerve stimulation and not using the muscles can lead to atrophy.

What is muscle hypertrophy?

Hypertrophy is the enlargement of muscles due to increased use or weight lifting.

What role do capillaries play in muscle function?

Capillaries provide resistance to fatigue in muscle fibers.

What is the effect of microtears on muscles?

Microtears can lead to muscle recovery and eventual strengthening.

What processes are involved in restoring muscle conditions post-exercise?

Restoration involves converting pyruvate from glycolysis and addressing oxygen debt.
