Engaging in aerobic exercise makes skeletal muscles more resistant to fatigue

Explanation:

Aerobic exercises increase muscle strength and endurance.

Aerobic exercises use the oxygen present in the muscles to generate energy and prevent lactic acid buildup. These exercises help to utilize the fat reserves for energy production.

These exercises are a series of short and long duration which induce sustained periodic muscle contractions.

These activities mainly act on Type 1 or the slow-twitch muscle fibers which can sustain the maximal amount of contractions for even a long period.  

The application of slow-twitch muscle fibers and the presence of oxygen together helps to build the resistance to muscle fatigue of skeletal muscles.  

Anaerobic exercises are resistance exercises which builds muscle mass.
