Multiple Choice

Cardiorespiratory endurance is the ability to:

maintain balance while standing on one foot

sustain prolonged physical activity by efficiently delivering oxygen to muscles

increase muscle size through resistance training

generate quick bursts of speed

Verified step by step guidance

Step 1: Understand the concept of cardiorespiratory endurance. It refers to the ability of the cardiovascular and respiratory systems to supply oxygen to the muscles during sustained physical activity.

Step 2: Analyze the options provided in the problem. The correct answer should align with the definition of cardiorespiratory endurance, which involves prolonged physical activity and efficient oxygen delivery.

Step 3: Eliminate options that do not match the definition. For example, maintaining balance while standing on one foot is related to balance and coordination, not cardiorespiratory endurance.

Step 4: Similarly, increasing muscle size through resistance training is associated with muscular hypertrophy, not cardiorespiratory endurance. Generating quick bursts of speed is related to anaerobic power, not sustained activity.

Step 5: Select the option that matches the definition of cardiorespiratory endurance: 'sustain prolonged physical activity by efficiently delivering oxygen to muscles.'
