n as Excess Post-Exercise Oxygen Consumption (EPOC), increases oxygen consumption after physical activity. This effect is essential for fitness because it can help:
- Boost metabolism: The after-burn effect can raise your metabolism after exercise, increasing the number of calories burned even when you are not actively working out.
- Improve fitness: By increasing the amount of oxygen your body uses after exercise, the after-burn effect can improve cardiovascular fitness and endurance.
- Increase calorie burns: The increased metabolism and oxygen consumption can lead to a higher overall calorie burn, which can be helpful for weight loss and body composition goals.
- Build muscle: High-intensity workouts that elicit a strong after-burn effect can also help build muscle and increase strength.
It’s important to note that the magnitude of the after-burn effect can vary depending on several factors, such as the intensity and duration of the exercise and the individual’s fitness level and body composition. However, incorporating high-intensity interval training (HIIT) and resistance training into your fitness routine can help maximise the after-burn effect and improve overall fitness.
The intensity required to create an after-burn effect depends on your personal fitness level. Still, in general, it should be at or above your anaerobic threshold, which is the level of intensity at which your body can no longer produce energy aerobically. The anaerobic threshold is typically around 80-90% of your maximum heart rate.
To determine your maximum heart rate, you can use the formula:
Max Heart Rate = 220 – Age
So, if you are 40 years old, your maximum heart rate would be 180 beats per minute (bpm).
Based on this, your target heart rate for anaerobic training would be around 144-162 bpm (80-90% of 180 bpm).
It’s important to remember that these are just rough estimates, and your actual anaerobic threshold may be higher or lower. Additionally, the best way to determine your anaerobic threshold is through a graded exercise test, which can be performed under the guidance of a doctor or exercise professional.
