A maximum aerobic function (MAF) heart rate training approach uses a formula to calculate an individualized training heart rate range designed to optimize aerobic function and endurance. This method typically involves subtracting one’s age from 180, and potentially adjusting this number further based on factors like current fitness level, recent illness, or pregnancy.
Training within the MAF zone is believed to improve aerobic efficiency by encouraging the body to primarily use fat as fuel. This approach prioritizes low-intensity, sustained-effort exercise, contrasting with high-intensity interval training (HIIT) methods. By focusing on aerobic development, athletes and fitness enthusiasts may experience improved endurance, enhanced recovery, and potentially reduce the risk of overtraining.
