How to Avoid the Telltale Signs of Exercise Intolerance

The symptoms of exercise intolerance are similar to those of other types of exercise-induced illness (EIIA). However, there is one difference: the signs and symptoms usually appear within a few days after strenuous physical activity. These signs and symptoms include fatigue, muscle aches, headaches, nausea/vomiting, dizziness or lightheadedness, difficulty concentrating or remembering things. Some people experience these symptoms even when they have not exercised at all.

These symptoms may seem like they are caused by something else, but if you do some research, it becomes clear that they are probably due to your body’s reaction to too much stress. You might think that you’re just tired from working out or doing other activities, but actually your body is trying to protect itself against the damage that could occur during an intense workout.

Exercise intolerance is often misdiagnosed as another type of EIIA. But, exercise intolerance is different because it affects both aerobic and anaerobic capacity. For example, someone with asthma may suffer from exercise intolerance while someone with heart disease does not.

So, the diagnosis of exercise intolerance should always be made based on your specific symptoms rather than on a general assessment of how well you’re doing at work or school. It’s important to get the right treatment if you suffer from exercise intolerance so that you don’t do further damage to your body.

There are physiological reasons why your body does not perform well during exercise. Even though everyone has different symptoms of exercise intolerance, there are consistencies in these symptoms too. The main problem is that the chemical reactions and nerve signals are not transmitted correctly to your muscles and organs because of a decreased supply of oxygen.
