The correct answer is B. sustain a regular routine of exercise for 30–60 minutes with minimal fatigue.
To determine the correct answer, it helps to understand what being aerobically fit means. Aerobic fitness refers to the ability of your cardiovascular system to efficiently supply oxygen to your muscles during sustained exercise. It is typically measured by your maximum oxygen consumption (VO2 max), which reflects how well your body can utilize oxygen during physical activity.
If you are aerobically fit, it means your cardiovascular system is strong and efficient, allowing you to engage in extended periods of aerobic exercise with less fatigue. This includes activities like running, cycling, swimming, and other forms of continuous exercise that elevate your heart rate for an extended period.
Option A, quitting your normal exercise routine without any negative effects, is incorrect. Just because you are aerobically fit doesn't mean you can stop exercising altogether without experiencing some decline in fitness over time. The benefits of aerobic fitness are maintained through regular exercise.
Option C, lifting very heavy weights without injuries to your joints, is unrelated to aerobic fitness. Aerobic fitness primarily focuses on the cardiovascular system's capacity, while heavy weightlifting involves muscular strength and joint stability. Both are important for overall fitness, but they are different aspects.
Option D, running a marathon without experiencing fatigue, is inaccurate. While being aerobically fit can help you run longer distances with reduced fatigue, running a marathon is a highly demanding activity that will still lead to fatigue, even for the most aerobically fit individuals. Proper training, nutrition, and pacing are essential for marathon runners.
To summarize, being aerobically fit means you can sustain a regular routine of exercise for 30–60 minutes with minimal fatigue. This answer aligns with the understanding of aerobic fitness and its effects on endurance exercise.
