Muscle fatigue is a common symptom of exercise, but it can also be caused by medications or health conditions such as arthritis, heart failure, anemia, dehydration, depression, and hepatitis C. It is characterised by a reduced ability to produce force with your muscles, which can make it harder to move and limit what you can do during exercise and daily life. Muscle fatigue can feel like tiredness or a lack of energy during or after a workout, and your muscles may feel floppy, weak, or achy.

Muscle fatigue can be caused by exercise, ageing, immobility, arthritis, heart failure, and more
Muscle fatigue can be caused by a variety of factors, including exercise, ageing, immobility, arthritis, heart failure, and more. It is characterised by a reduced ability to produce force with your muscles, resulting in feelings of weakness, tiredness, and a lack of energy.
During exercise or strenuous activity, your muscles initially feel strong and resilient. However, as you continue repeating movements, muscle fatigue can set in, causing your muscles to feel weaker and more tired. This decrease in muscle performance is often associated with a state of exhaustion.
Short-term muscle fatigue, also known as acute muscle fatigue, is commonly experienced during or after intense workouts. It may manifest as a general feeling of tiredness or a lack of energy. Your muscles may feel floppy, and you might experience a reduced capacity to generate force, leading to a sense of frailty.
Chronic muscle fatigue, on the other hand, is long-term and can be caused by conditions such as arthritis and heart failure. It is characterised by persistent muscle weakness, aches, and limitations in movement. Chronic muscle fatigue can significantly impact your daily life and exercise routines.
Muscle fatigue can also be a side effect of certain medications or health conditions like anaemia, dehydration, depression, and hepatitis C. Additionally, overtraining can lead to delayed-onset muscle soreness (DOMS), which typically occurs between 24 and 48 hours after exercising. DOMS includes symptoms such as inflammation, loss of strength, muscle aches, and fatigue.

Muscle fatigue can feel like tiredness or a lack of energy
Muscle fatigue is usually acute (short-term) and reversible, often occurring during or after a workout. It can be caused by overtraining, dehydration, or as a side effect of certain medications. It can also be a symptom of long-term health conditions such as arthritis, heart failure, or hepatitis C.
Short-term muscle fatigue is different from delayed-onset muscle soreness (DOMS), which occurs between 12 and 48 hours after a strenuous workout or a particular movement you don't usually do. DOMS can include inflammation, loss of strength, muscle aches, and fatigue, and it usually goes away within a week.
Chronic (long-term) muscle fatigue can result from disease, aging, and immobility. It can make your muscles feel floppy and frail, and it may be a symptom of conditions such as arthritis and heart failure.

Muscle fatigue can cause a reduced ability to produce force with your muscles
Muscle fatigue is a reduced ability to produce force with your muscles. It can be caused by exercise, ageing, immobility, or certain medications and health conditions. It can also be a symptom of conditions such as arthritis and heart failure. Muscle fatigue can make it harder to move and limits what you can do during exercise and daily life. It can feel like tiredness or a lack of energy during or after a workout, and your muscles may feel weak and ache. With chronic muscle fatigue, your muscles can feel floppy and frail, as they are only able to generate low force. Short-term muscle fatigue is different from delayed-onset muscle soreness (DOMS), which is the muscle tenderness and pain you feel 12-24 hours after a strenuous workout or a particular movement you don't usually do. DOMS can also include inflammation, loss of strength, and fatigue, and usually goes away within a week. Rest is one of the best ways to fix short-term muscle fatigue, and your muscles typically fully recover within three to five days.

Muscle fatigue can be relieved by rest, compression garments, stretching, foam rolling, and massage
Muscle fatigue can be defined as a reduction in your muscles' ability to perform over time. It can be caused by exercise, ageing, immobility, or health conditions like arthritis and heart failure. It can also be a side effect of certain medications. Muscle fatigue can be acute (short-term) or chronic (long-term). Short-term muscle fatigue may feel like tiredness or a lack of energy during or after a workout. Your muscles may feel weak and ache, and you may experience muscle tenderness and pain. This is known as delayed-onset muscle soreness (DOMS), which usually occurs between 24 and 48 hours after exercising and can last up to a week.
There are several ways to relieve muscle fatigue:
- Rest: Allow your muscles to recover by taking a break from exercise. The duration of rest depends on the intensity and duration of the workout, typically ranging from three to five days for full recovery.
- Compression garments: Special clothing that fits tightly around the skin can aid in muscle recovery and reduce fatigue.
- Stretching: Gentle stretching can help relieve muscle soreness and improve flexibility.
- Foam rolling: Self-myofascial release through foam rolling can help reduce muscle tension and promote recovery.
- Massage: Getting a massage can increase blood flow to the muscles, reduce inflammation, and alleviate muscle pain associated with fatigue.
By incorporating these strategies into your routine, you can effectively manage muscle fatigue and promote faster healing.
