This Is How Your Body Burns Energy After Working Out
Although many might not know it, the body burns energy after working out. Especially when doing strength or interval exercises, muscles increase their caloric expenditure for a few hours after the activity ends.
But not all types of sports have a similar energy expenditure. It’s therefore important to know both the exercises that burn the most calories and those that increase basal energy expenditure when you’re at rest.
Here’s how much energy your body burns after working out.
Your body burns little energy after an aerobic workout
Endurance sports are characterized by low energy expenditure even if sustained for long periods of time. In this type of exercise, fat oxidation prevails over the use of carbohydrates as the main energy source.
With these are exercises you can achieve a calorie deficit, but only from long training sessions. However, improper nutrition can lead to muscle catabolism as a result of endurance activities for a sustained period of time.
To avoid this, which compromises resting energy expenditure, it’s essential to optimize protein intake. A study published by the PLoS One journal demonstrates that protein requirements are higher in endurance athletes to guarantee a positive nitrogen balance.
Nevertheless, the body is able to continue burning energy after the workout is over. This is because restoration of the hormonal system and DNA repair are processes that need the energy to take place.
Said energy consumption is greater the more intense the physical activity. For this reason, it’s more significant in anaerobic sports.
Anaerobic workouts increase basal metabolic rate
Anaerobic workouts influence hormonal processes by increasing muscular stress and mechanical tension. Strength exercises increase testosterone production, according to research published in the Journal of Strength and Conditioning Research.
Thus, doing intense squats and deadlifts with heavy weights increases anabolic hormone secretion, which affects energy expenditure after training.
In general, anaerobic exercises have a maximum strength component. Developing large amounts of mechanical stress increases the metabolic stress athletes are subjected to. Hormonal and nutritional compensations are higher and therefore, compared to aerobic sports, the energy expenditure after a workout session increases.
Building strength is usually an effective way to lose weight. In fact, the energy balance starts to “lean” more towards energy expenditure for two reasons: the caloric demand of the activity itself and that after the end of the activity.
In any case, it’s necessary to complement exercise with a proper diet in order to observe medium-term results in body composition.
Not all exercises burn the same energy after training
As we’ve mentioned before, compared to endurance sports, anaerobic and strength exercises increase caloric expenditure after activity. This is because hormonal and metabolic adaptations are much greater.
As the mechanical stress exerted increases, the production of anabolic hormones also increases. These have a direct impact on building muscle mass and energy requirements.
Endurance workouts demand more energy, especially if you’re doing them for several hours at a time. However, the energy expenditure per hour is significantly lower and so is the amount of energy that the body burns once the workout is over.
If your goal is losing weight, you could create your own aerobic and anaerobic training program, but you must pay attention to your diet as well. If calorie intake exceeds calorie expenditure, it’ll be impossible to reduce your body fat percentage.It might interest you...
