Heart rate reserve is a crucial component in determining exercise intensity using the Karvonen method. To calculate heart rate reserve, you start with the maximum heart rate, which is traditionally estimated using the formula 220 minus the person's age. From this maximum heart rate, you subtract the resting heart rate (RHR). This calculation allows you to find the heart rate reserve, which represents the range of heart rates available for exercise intensity.

Using the formula provided, 220 minus age gives you the maximum heart rate. By then subtracting the resting heart rate, you effectively adjust for individual fitness levels and resting conditions. This method allows trainers and individuals to tailor exercise programs that match specific cardiovascular fitness goals, ensuring that workouts are conducted within personalized heart rate zones for optimal effectiveness. Therefore, the calculation of heart rate reserve as maximum heart rate minus resting heart rate is accurately represented in the chosen option.
