Introduction
The effects of exercise on our bodies are unique and unparalleled. Whether you are trying to lose weight, improve physical fitness, or simply want to stay healthy, regular exercise affects your body’s metabolism. A common question that often arises is, “How long does exercise increase basal metabolism?” In this article, we will discuss in detail how exercise affects basal metabolism and how long this effect lasts.
What is Basal Metabolism?
Basal metabolism refers to the energy our body expends to survive at rest. It does not include energy expenditure related to physical activities but rather refers to the energy required to maintain normal body functions such as respiration, digestion, blood circulation, and body temperature. When we exercise, our body expends more energy, which can increase the rate of metabolism.
The relationship between exercise and metabolism

Exercise increases our body’s metabolism immediately. When we engage in physical activity, such as running, weight lifting, or cardio, our body uses more energy. This increases the basal metabolic rate, and our body burns more calories over a long period.
Types of exercise and its effect on metabolism
- Aerobic Exercise: Such as running, cycling, and swimming. These exercises increase the body’s heart rate and help burn more calories. Regular aerobic exercise can increase basal metabolism, which can last several hours.
- Weight training: Weight lifting exercises help strengthen muscles and increase metabolism. Building muscle mass reduces body fat, and having more muscle helps burn more calories, even while at rest.
- High-intensity interval training (HIIT): HIIT is a type of exercise that involves bouts of high-intensity exercise followed by periods of rest. It not only boosts metabolism immediately but its effects can be felt for up to 24-48 hours.
Timing of effect on metabolism after exercise
Now the question arises, “How long does the effect on basal metabolism last after exercise?” This time depends on the person’s physical condition, exercise intensity, and type of exercise. For example:
aerobic exercise:
Aerobic exercise, such as long runs, can increase your metabolism for 30-60 minutes, and this effect can be felt for 1-2 hours. However, if you do aerobic exercise regularly, this effect can be permanent.
Weight training:
Weight training promotes muscle growth, and the more muscle you have, the more calories you burn. Additionally, weight training can increase your metabolism for the next 24-48 hours, as the body needs more energy to repair muscle.
HIIT (High-Intensity Interval Training):
HIIT exercises can increase metabolism immediately and keep it elevated for 24-48 hours. This exercise speeds up the calorie-burning process and prompts the body to burn fat for a longer period of time.
Other ways to increase basal metabolism after exercise

Besides exercise, there are several other ways you can increase your basal metabolism. These include:
Protein-Rich Diet:
Protein intake increases metabolism, as the body requires more energy to digest protein. In addition, protein helps build muscle, which can increase basic metabolism.
Hydration:
Every cell needs water to function properly. Adequate water intake helps keep the metabolism running smoothly and regulates body temperature, which helps burn more calories.
Good Sleep:
Lack of sleep can slow down metabolism. Getting enough sleep maintains the body’s energy levels and improves basic metabolism.
Maintaining a balance between exercise and basal metabolism
It is not possible to increase basal metabolism by exercising alone. You need to lead a balanced lifestyle that includes proper diet, adequate sleep, and mental health. Apart from physical fitness, mental health also affects the overall metabolism of the body.
Conclusion
Exercise increases basal metabolism, and this effect depends on the type, intensity, and regularity of exercise. Aerobic exercise causes an immediate increase in metabolism, while weight training and HIIT exercises can improve metabolism over a long period. Maintaining a healthy and balanced lifestyle can increase metabolism permanently.
FAQs
1. How long does exercise increase basal metabolism?
Exercise can increase basal metabolism for anywhere from a few hours to 24 hours. This increase depends on the intensity and duration of the exercise. Metabolism may remain elevated for longer after high-intensity exercise.
2. Does regular exercise cause a permanent increase in basal metabolism?
Yes, regular exercise can lead to a permanent increase in metabolism. In particular, strength training increases muscle mass, which can increase basal metabolism over the long term.
3. Does cardio exercise increase basal metabolism?
Yes, cardio exercise also increases basal metabolism, but this increase is usually short-lived. This exercise helps the body burn more calories, giving the metabolism a slight boost.
4. How does basal metabolism slow down after exercise?
Basal metabolism can slow down after exercise if you don’t rest enough or if your body isn’t getting enough nutrients. Adequate sleep and the right diet help maintain metabolism.
5. Does muscle growth increase basal metabolism?
Yes, muscle growth increases the basal metabolism. More muscle mass is responsible for burning more calories in the body, and this leads to an increase in basal metabolism, which can help in weight loss.
