The Tanaka formula is specifically designed to calculate maximum heart rate. It uses the equation 208 - (0.7 × age) to provide an estimate of the upper limit of heart rate that an individual should not exceed during exercise, which is crucial for designing safe and effective training programs. Understanding the maximum heart rate is important for personal trainers as it helps to establish appropriate intensity levels for clients, ensuring that workouts are challenging yet safe. This tool is particularly useful in aerobic training and cardiovascular fitness assessments, allowing trainers to tailor exercise plans based on clients' specific age and fitness levels.

In contrast, the other options focus on different aspects of fitness or physiology. Minimum heart rate for exercise relates to the lowest effective heart rate for physical activity, while target metabolic equivalent pertains to energy expenditure and how it correlates with physical activities. Ideal body weight involves different calculations entirely, generally focusing on body composition and health assessments rather than heart rate. Each of these other elements is important in fitness training, but they do not pertain to what the Tanaka formula specifically measures.
