What exactly is exercise intolerance?

Exercise intolerance is defined as a diminished capacity to exercise at a level appropriate for one’s age and size. People with exercise intolerance may be unable to exercise as energetically as they formerly could, or they may become weary or out of breath immediately after beginning to exercise.

The amount to which exercise intolerance affects individuals varies greatly. Some people may be able to engage in certain types of exercise, but they will have to quit sooner than they did before. Others may be unable to engage in any physical exercise owing to their symptoms.

Is exercise intolerance synonymous with a lack of fitness?

Exercise intolerance is not synonymous with a lack of physical fitness.

Those who have not exercised in a long time may usually benefit from physical activity and gradually develop their strength. The more they develop acclimated to managing exercise, the more they can perform easily.

Exercise intolerance symptoms

The major symptom of exercise intolerance is an inability to participate in a decent degree of physical activity on a regular basis. This might cause someone to feel:


I’m out of breath


in distress


Muscle cramps, dizziness, or postexertional sickness may also occur depending on the reason (PEM).

PEM, like exercise intolerance, may prohibit people from exercising or being physically active. PEM, on the other hand, generates a delayed response where exercise intolerance makes it harder to begin or maintain exercising in the present.

With PEM, a person’s preexisting medical issues worsen after 12-48 hours Trusted Source of exertion. It may persist anywhere from a few days to a few weeks, and because of the delayed onset, individuals might not always realise they have done too much physical activity.

What factors contribute to exercise intolerance?

People who have underlying diseases that interfere with blood circulation, respiration, metabolism, or energy might develop exercise intolerance. These issues may be caused by a variety of circumstances. Some instances are as follows.

Respiratory problems

Asthma, chronic obstructive pulmonary disease, and lung cancer may all make it more difficult to acquire adequate oxygen owing to a diminished capacity to breathe. Depending on the intensity of the symptoms, this may result in varied degrees of exercise intolerance.

When people with respiratory disorders exercise, they may feel short of breath, lightheaded, or dizzy. Strenuous exertion may also cause coughing or asthma symptoms such as wheeze or chest tightness.

COVID and post-viral syndrome

After a viral infection, patients may have chronic weariness and weakness for weeks or months. This is referred to as post-viral tiredness or post-viral syndrome by medical professionals.

After the COVID-19 pandemic, many people have acquired a post-viral syndrome as a result of a SARS-CoV-2 infection, which is referred to as protracted COVID. Exercise intolerance may be caused by both post-viral syndrome and extended COVID.

Practitioners do not know why post-viral syndrome or extended COVID arise, although they may be caused by the immune system being hyperactive even after the illness has cleared. This might also explain why patients have a sore throat, enlarged lymph nodes, and body pains.

Myalgic encephalitis, also known as chronic fatigue syndrome

Myalgic encephalitis, often known as chronic fatigue syndrome (Urgent), is characterised by a persistent loss of energy that does not improve with rest or sleep. For this syndrome to be diagnosed, symptoms must endure for at least 6 months. Reliable Source. Those with the illness may be unable to exercise or participate in a variety of other activities.

Physician are unsure why ME/CFS occurs, however some people get the symptoms after a viral infection or after enduring substantial stress. It’s comparable to post-viral syndrome, although not everyone can pinpoint a precise trigger event.


Diabetes affects how the body responds to and consumes glucose, which provides energy to cells. According to a 2015 research, exercise intolerance may arise in persons with type 2 diabetes regardless of other conditions that may impede exercise, such as cardiovascular disease.

Diabetes-related exercise intolerance arises when blood vessels do not function properly, resulting in decreased circulation. This makes it difficult for people with type 2 diabetes to exercise, which is typically require as part of diabetes care.

Myopathies caused by metabolic processes

Metabolic myopathies are hereditary diseases that affect how the body utilises energy. For those with these disorders, excessive physical activity may cause muscles to break down in a painful process known as rhabdomyolysis, which can harm the kidneys.

There are several forms of metabolic myopathy, although many of them produce similar symptoms, such as:

intolerance to exercise

cramping in the muscles

heart issues

urine with a rusty tint

A disease of the motor neurons

Motor neuron disorders are a collection of ailments that develop when the brain and nerves are unable to connect with muscles, resulting in movement issues. This results in weakened muscles, an inability to move, and increasing tiredness levels over time.

Multiple sclerosis and amyotrophic lateral sclerosis are two instances of motor neuron disorders. Muscle weakness, cramps and spasms, weariness, and unexplained weight loss are early indications.

According to a 2020 editorial, experts disagree on whether any quantity of exercise is detrimental or useful to patients with various forms of motor neuron disease.

Heart attack

Any cardiac ailment that limits the heart’s capacity to pump blood may make exercise more difficult, but exercise intolerance, in particular, is a significant indication of chronic heart failure. Heart failure happens when the heart can no longer adequately pump blood throughout the body.

A research found that exercise intolerance in persons with heart failure is associate with worse outcomes and a greater risk of cardiac arrest. Nevertheless, if physicians can figure out what’s causing it, they may be able to enhance people’s ability to exercise.

What aids in the treatment of exercise intolerance?

The way individuals deal with exercise intolerance is heavily influence by the underlying reason. Any level of physical exercise may be unhealthy or even hazardous to certain people. Some may find that exercising within specified restrictions is useful.

The first step in dealing with chronic exhaustion or incapacity to exercise is to consult with a doctor. It is essential to identify the source of exercise intolerance and rule out any significant disorders.

This procedure may be aid by:

Locating a qualified physician: Most medical schools in the United States do not train physicians about ME/CFS, according to the Centers for Disease Control and Prevention (CDC)Trusted Source. This might make it difficult for persons suffering from energy-limiting diseases to get a diagnosis or assistance. Get second or third views if needed, or have someone attend appointments as an advocate.

Individual limits: It is beneficial to determine how much exercise or activity a person can endure without worsening symptoms. Keep a journal to monitor the kind and degree of activities a person engages in, as well as any symptoms that arise. Note that even mundane things like cleaning may be physically challenging.

Lowering energy output: Individuals who have exercise intolerance may benefit from changing their movement patterns to lessen effort. This might involve sitting to prepare meals or fold laundry, or utilising assistive equipment, such as a shower stool. An occupational therapist might help with adjustments.

Pacing is a strategy that involves arranging chores ahead of time in order to keep them from becoming too taxing. People may, for example, space out activities that require a lot of energy and schedule time before and after for rest and recuperation.

Listening to the body: Rather than attempting to keep to a particular workout goal or to-do list, take clues from symptoms and how the body feels. Increase physical activity only when it seems safe to do so, and avoid pushing through exhaustion or discomfort.

In certain cases, chores are too difficult for those with exercise intolerance. Try not to go through things alone whenever feasible. Simple tasks, such as lugging heavy groceries, might be done by friends, family, or neighbors.

Chest pain and discomfort Exercise intolerance may cause you to have chest pain or discomfort in your left arm, back, and neck. This can arise from exercises such as bench presses and lifting weights.

Exercise intolerance happens when you have breathing difficulties after a short period of exercise. When oxygen fails to get circulate in your body, you tire easily and can no longer tolerate movement. If you are unfit and unhealthy, you can have signs of exercise intolerance.
