Exercise is effective for recovering from fatigue! How to relieve fatigue from training and everyday life

"Active rest" improves recovery! The scientific reason why exercise is effective against fatigue

There is a scientific reason why exercise helps to recover from fatigue.
This is because exercise improves stagnant blood flow and efficiently eliminates fatigue substances that have accumulated in the body.

Active rest, which involves light exercise, speeds up the recovery of damaged muscles and reduces fatigue, rather than complete rest where you do nothing.

Promotes blood circulation and expels fatigue-causing substances smoothly

When muscles contract and relax repeatedly during exercise, they act like a pump, improving blood circulation throughout the body.
Improved blood flow allows lactic acid and waste products that cause fatigue to be efficiently transported out of the muscles, where they are broken down and removed.
On the other hand, if you do not move your body at all, blood circulation will be impeded and fatigue substances will tend to accumulate.

This can make it difficult to shake off fatigue and leave you feeling lethargic until the next day.
Moderate exercise plays an important role in breaking this cycle and speeding up recovery.

Balances the autonomic nervous system and relaxes the mind and body

Fatigue is also closely related to autonomic nervous system disorders.
If the sympathetic nervous system, which becomes dominant during daytime activities, does not calm down at night, the mind and body will remain in a state of tension and you will not be able to get good quality sleep.
Light exercise has the effect of gently increasing the activity of the parasympathetic nervous system, which is responsible for relaxation.

Exercise, especially one that involves deep breathing, can help slow your heart rate and put your mind and body into a relaxed state.
This allows you to experience a deep sense of relaxation that you cannot get by simply sleeping, improving the quality of your sleep and allowing you to wake up refreshed the next morning.

[By purpose] Recommended exercise menu for fatigue recovery that you can start today

If your goal is to recover from fatigue, you don't need to train hard.
Rather, light exercise that feels comfortable is best.
Here we will introduce four exercise menus that can be easily incorporated into your daily life and are effective in refreshing your mind and body.

Please try practicing within your limits, according to your own physical condition and preferences.

Walking for about 20 minutes increases blood flow throughout the body

Walking is a typical aerobic exercise that anyone can easily start, and does not require any special equipment.
Walking rhythmically for around 20 minutes with your arms swinging slightly wider will stimulate muscles throughout your body and improve blood circulation.
If you aim for a pace that allows you to have a conversation with the person next to you, your heart rate won't rise too much and you'll be able to maintain an exercise intensity that's optimal for recovering from fatigue.

Walking while enjoying the scenery can help you change your mood and reduce mental stress.
It is recommended to find some spare time in your daily life to incorporate this into your daily routine, such as getting off one stop early and walking when commuting, or taking a walk around the area around your office during your lunch break.

Stretching after a bath to release muscle tension

Stretching after warming your body in the bath is a great opportunity to increase muscle flexibility and help recover from fatigue.
When you do this after your blood circulation has improved from bathing, your muscles will be easier to stretch, effectively relieving muscle tension that has become stiff from daytime activities or desk work.
In particular, be conscious of slowly stretching large muscles such as those around the shoulder blades, hip joints, and the back of the thighs.

The key is to hold the position for 20 to 30 seconds within a comfortable range that doesn't cause pain.
Doing this before bedtime will activate the parasympathetic nervous system, helping you fall asleep in a relaxed state.

Relieve stiffness in mind and body with yoga that focuses on deep breathing

Yoga not only increases the flexibility of the body through poses, but also has the effect of balancing the autonomic nervous system through deep breathing.
In particular, movements that involve curving and arching the back, such as in cat pose, can loosen the muscles around the spine, which tend to become stiff, and help relieve lower back pain and stiff shoulders.
By slowly maintaining the pose while focusing on abdominal breathing, you will be able to release tension in your body and mind and enter a state of deep relaxation.

There is no need for intense movements; listen to your body and prioritize feeling a comfortable stretch.
It is also recommended when you are feeling mentally fatigued.

Refresh yourself by jogging at a pace that allows you to chat

Light jogging is also an effective way to recover from fatigue.
The key is to keep a slow pace that allows you to chat with someone while running, rather than pushing yourself so hard that you run out of breath.
Exercise at this intensity is said to stimulate the release of serotonin, a neurotransmitter that promotes mental stability and elevates mood.

By promoting blood flow throughout the body and taking in fresh oxygen, it helps to refresh not only physical fatigue but also mental fatigue.
Start with 15 to 20 minutes as a guide, within your limits of what you can comfortably sustain.

Three points to maximize the effects of exercise on fatigue recovery

If you do exercise aimed at recovering from fatigue blindly, the effect may be halved.
You can maximize the benefits of exercise by paying attention to three elements: exercise intensity, timing, and nutrition.
Here we will explain some specific points to make active rest more effective.

Maintain a comfortable intensity that makes you feel like you can breathe easily.

The most important thing about exercise for recovery is setting the right intensity.
Exercising so hard that you run out of breath or training for long periods of time can actually put strain on your body and cause further fatigue to accumulate.
The recommended level of intensity is one that makes you a little out of breath but still allows you to smile and talk.
In terms of heart rate, an ideal heart rate is around 60% of your maximum heart rate.

By maintaining this "comfortable" level, it is possible to maximize the beneficial effects of the massage, such as promoting blood circulation and relaxation, which are beneficial for recovering from fatigue.
The most important thing is not to overdo it.

Use it to cool down after exercise or relax before bed

The timing of recovery exercise is also important.
When used as a cool-down exercise immediately after training or intense exercise, it gradually calms the heart rate and helps eliminate fatigue-causing substances that have accumulated in the muscles.
It's also effective to do this at the end of the day, especially before bedtime, to relax.

Light stretching and yoga can help relieve tension in the mind and body and stimulate the parasympathetic nervous system, leading to better quality sleep.
By incorporating it into your daily routine, you can make it a habit without any strain and it will help you improve your daily condition.

Post-exercise nutrition for faster recovery

Combining exercise with proper nutrition will further enhance your recovery.
Nutrients such as carbohydrates and protein are essential for replenishing the energy consumed during exercise and repairing damaged muscle fibers.
The period within 30 minutes after exercise is known as the "golden time," when nutrient absorption is at its highest, making it ideal to eat at this time.

Another good way to do this is to take advantage of protein and amino acid supplements, foods such as bananas and rice balls, and sports drinks.
If you are feeling very tired, one option is to drink a nutritional drink containing B vitamins.

Are exercise counterproductive when you're fatigued?

Light exercise can be effective for many types of fatigue, but in some cases it can hinder recovery and make symptoms worse.
For example, if you have obvious signs of illness such as fever, headache, or dizziness, your top priority should be rest.
It is also wise to avoid exercise if you are extremely tired due to lack of sleep, your vision is blurred, and your concentration is significantly reduced.

Forcing yourself to exercise in this condition can weaken your immune system and increase the risk of injury.
It's important to listen to your body and determine whether you're tired and need to rest or move around a bit.

Frequently asked questions about recovery exercise

Here we will answer questions that many people have about exercise for the purpose of fatigue recovery.
Please use this as a reference for concrete tips to put into practice in your daily life.

Q1. What exercises are recommended to relieve stiff shoulders and lower back pain caused by desk work?

Here are some easy stretches you can do while sitting.
Simply rotating your neck slowly and lifting your shoulders for about three minutes can improve your blood circulation.
For the lower back, an effective stretch is to sit shallowly in a chair and twist your body.

The key to relieving this is to do it regularly and be conscious of not maintaining the same posture for long periods of time.

Q2. What should I do if I'm too busy to find time to exercise?

It is effective to incorporate "exercise while doing other things" into your daily life.
Make a conscious effort to increase your physical activity by switching from an escalator to stairs or by lifting your heels up and down while brushing your teeth.
Simply getting into the habit of moving your whole body for a short period of time, such as doing radio calisthenics once a day, can help prevent fatigue from accumulating.

Q3. Will exercising help me recover faster even when I have severe muscle pain?

If you have severe muscle pain that is so severe that it is difficult to move, do not force yourself to exercise and prioritize rest.
Low-intensity exercise such as light walking and stretching can improve circulation and aid recovery, but if the pain worsens, stop immediately.
Icing and nutritional support are also effective.

Conclusion

When you feel tired, "active rest," which involves not only resting but also light exercise, effectively promotes recovery.
Promoting blood circulation through exercise helps eliminate fatigue-causing substances and contributes to relaxation of the mind and body by balancing the autonomic nervous system.
It is important to incorporate exercise at a comfortable intensity, such as walking or stretching, into your daily routine.

However, if you are not feeling well or are extremely tired, you should avoid exercise and rest.
Along with exercise, ensure you get the proper nutrition to help manage your daily condition.
