Question

select the correct answer.

which statement about anaerobic exercises is true?

• you should leave at least a day between anaerobic exercises to let muscles rest and heal.
• anaerobic exercise should last longer and be more intense than aerobic exercise.
• during anaerobic exercise the muscles require a lot of oxygen.
• anaerobic exercise is mostly intended to improve cardiorespiratory endurance.

Explanation:

Analyze the characteristics of anaerobic exercise

Anaerobic exercise involves short, intense bursts of activity where the body's demand for oxygen exceeds the oxygen supply available. Because of the high intensity, muscle fibers experience micro-tears and require adequate recovery time to rebuild and strengthen.

Evaluate the given options

• Option 1: Leaving at least a day between anaerobic sessions allows muscles to rest, repair, and prevent overtraining. This is a true and recommended practice.
• Option 2: Anaerobic exercises are highly intense but are short in duration (seconds to a few minutes), not longer than aerobic exercises.
• Option 3: Anaerobic means "without oxygen," so muscles do not rely on oxygen for immediate energy production during the activity.
• Option 4: Aerobic exercise, not anaerobic, is primarily intended to improve cardiorespiratory endurance.

Answer:

• (A) You should leave at least a day between anaerobic exercises to let muscles rest and heal. (Correct answer)
• (B) Anaerobic exercise should last longer and be more intense than aerobic exercise.
• (C) During anaerobic exercise the muscles require a lot of oxygen.
• (D) Anaerobic exercise is mostly intended to improve cardiorespiratory endurance.
