Verified step by step guidance

1. Understand the context of the question: The problem is asking you to identify the correct statement related to physical fitness, which includes concepts like VO2 max, cardiorespiratory fitness, muscular strength, and the role of diet and physical activity.
2. Analyze the first statement: VO2 max is a measure of the maximum amount of oxygen the body can utilize during intense exercise. It is primarily used to assess cardiorespiratory fitness, not muscular strength and endurance.
3. Evaluate the second statement: Cardiorespiratory fitness is not determined by body mass index (BMI). BMI is a measure of body weight relative to height and does not directly assess the efficiency of the cardiovascular and respiratory systems.
4. Examine the third statement: Muscular endurance, not just muscular strength, is determined by how many repetitions of an exercise you can complete. Muscular strength refers to the maximum force a muscle can exert in a single effort.
5. Conclude with the correct statement: The final statement is accurate. Achieving physical fitness requires a combination of regular physical activity and a healthful diet, as both are essential for overall health and well-being.
