Question 12 of 20Which kind of exercise helps your heart work more efficiently?A.Strength trainingB.Flexibility trainingC.Aerobic exerciseD.Anaerobic exercise

Break Down the Problem

1. Identify the exercise types listed in the question.
2. Determine the effects each exercise type has on heart efficiency.

Relevant Concepts

1. Aerobic exercise: This type of exercise raises your heart rate and is sustained over a period of time, improving cardiovascular endurance.
2. Strength training: Focuses on building muscle strength and does not have as significant an impact on heart efficiency.
3. Flexibility training: Primarily focuses on improving the range of motion, with little effect on cardiovascular health.
4. Anaerobic exercise: Includes short bursts of high-intensity effort; while it boosts power and strength, it is not primarily aimed at improving heart efficiency.

Analysis and Detail

• Aerobic exercise (such as running, swimming, or cycling) is specifically designed to improve cardiovascular health by ensuring the heart pumps more efficiently during prolonged activity.
• In contrast, strength training mainly increases muscle strength with less impact on the heart.
• Flexibility training does not contribute significantly to cardiovascular endurance.
• Anaerobic exercise has benefits for muscle and power but is not focused on heart efficiency over longer durations.

Verify and Summarize

From the analysis, the exercise that best helps the heart work more efficiently is clearly aerobic exercise, as it maximizes heart rate and stamina over an extended period.

Final Answer

C. Aerobic exercise
