At the start of exercising or when performing tasks, your muscles feel strong and resilient. However, over time and after repeating movements, your muscles may begin to feel weaker and tired. This can be defined as muscle fatigue.
Muscle fatigue is a symptom that decreases your muscles’ ability to perform over time. It can be associated with a state of exhaustion, often following strenuous activity or exercise. When you experience fatigue, the force behind your muscles’ movements decrease, causing you to feel weaker. Exercise and other physical activity are a common cause of muscle fatigue. Other possible causes of this symptom include: Addison’s disease age, anemia, anxiety, cerebral palsy, chronic fatigue syndrome (CFS), dehydration, depression, hepatitis C, HIV, influenza (the flu), lack of exercise, lactic acid production, medications, mineral deficiency, muscular dystrophy, myositis (muscle inflammation), poor muscle tone due to a medical condition, pregnancy, sleep deprivation, stroke, etc.
Muscle fatigue can occur anywhere on the body. An initial sign of this condition is muscle weakness. Other symptoms associated with muscle fatigue include: soreness, localized pain, shortness of breath, muscle twitching, trembling, a weak grip, muscle cramps. If you begin having difficulty performing daily tasks or if your symptoms worsen, seek immediate medical attention. This could be an indication of a more serious health condition.
