These changes are evident, but once you keep on going you will surpass this initial phase and feel more comfortable with more physical work. 

Your body prioritizes the activity you are doing and to achieve movement optimization some other functions of your body, like your stomach, take a momentary back seat, letting all the energy flow mainly to your muscles, heart, lungs, and skin sweat cells.

This adaptation aims to increase your oxygen flow, decrease your heat, and dedicate all the metabolic energy in the exercise.

Usually, these changes are not that obvious.

  • What happens to your body after one hour of exercise?

Depending on the type of exercise you are doing, your body can enter into three states depending on the energy it is using: The Phosphagen System, The glycolysis system, and the Aerobic system.

The Phosphagen System

It takes place for a quick burst of energy.

This state is limited (Only last 5-15 seconds) and only used for short scenarios like giving your all to the last sprint in a race.

This system uses energy stored as ATP, which is ready to burn and won’t require complicated metabolism.  

The Glycolysis system

Also called the anaerobic system takes place to compensate for the lack of oxygen. This state can last 1 to 3 minutes.

At this stage, you will burn down carbohydrates.

This process creates lactic acid, which it’s the biggest culprit of muscle pain the day after.

With the help of an expert coach, you can reduce the after-effects of this state. 

The Aerobic System

It is the state that kicks in after a long exercise routine.

Your body realizes you will not stop soon and starts using oxygen to obtain more energy.

At this point, you will truly burn as fuel the fat and carbohydrates stored in your body.

Achieving this state can be trained and requires long and low-intensity programs. 

Which system you go into depends on the type or the intensity of workouts you are doing, your oxygen flow, and the food you each before the exercise session.

Once you end your workout session, your body wants to return to the resting state and regain all the normal functions. The rate to achieve this depends on how to fit you are, the fitter you are, the easier and quicker it will be. 

All your system will slowly go back to a resting state while adapting and becoming stronger.

However, exercise can have a big impact on your body, and giving it time to readjust is vital.

All the functions that took a back-seat will go back to normal, which requires your blood flow to go back to its regular work and this can take a couple of minutes.  

At this point is common to feel muscle sore because while you are working out, your muscle tissue is tearing, and once you start resting it will be rebuilt more strongly.

This will increase your resistance and strength in the future but you need to rest, give your body time to adjust and repair. 

In some cases, if your body is not used to these sessions it is possible to see an over-compensation of the accelerated functions.

For example, while you are working out your blood pressure raises but once you start resting, your blood pressure can drop more than normal for a couple of minutes.

This is called “Post exercise-hypotension” and it’s a normal response that can be overcome by resting.

The time you need to recover after you are done with the workout will be less since you will improve your physical condition.

The more regular you keep the exercise, the more easily your body will adapt to all these changes.

To adapt better, your metabolism will increase its rate.

This can be clearly noted as an increase in your physical endurance and a greater appetite.

For these changes to take place it can require about 3 weeks of constant workout, but it depends on each person’s bodies and the kind of exercise done.

As another result, you will increase your build up muscles to keep on the physical activity that means that less tearing of muscular tissue and less muscular sore will take place with the same amount of exercise.

Your heart will gain benefits too since your cardiovascular capacity will improve.

Additionally, studies have shown that after exercise, more blood vessels are created which decreases your blood pressure.
