The Maximum Aerobic Function (MAF) formula, developed by Phil Maffetone, calculates a target heart rate for exercise aimed at optimizing fat burning and building an aerobic base. This formula typically involves subtracting one’s age from 180, with potential adjustments based on factors such as health conditions, training experience, and competitive goals. A tool facilitating this calculation, often available online, allows individuals to quickly determine their MAF heart rate.
Using this heart rate zone for training is believed to enhance endurance performance by improving the body’s ability to utilize fat as fuel, sparing glycogen stores for higher-intensity efforts. Historically, this approach challenged the conventional emphasis on high-intensity training, offering an alternative perspective focused on building a solid aerobic foundation. This foundation serves as a platform for increased training intensity later, potentially leading to greater performance gains and reduced risk of overtraining. It emphasizes long-term development over short-term gains.
