Muscle tremors may occur during exercise for a number of reasons. Most of the time, muscle tremors are not a sign of anything serious and they will usually respond well to rest and adequate hydration. However, continued occurrences of muscles that tremor should be brought to the attention of your doctor for further evaluation.
Muscle Tremor
Muscle tremors are discrete movements or contractions of a certain area of muscle. The more technical term for tremors is fasciculations. These fasciculations are uncontrolled in nature and can range from being completely normal and benign to early signs of a muscular or neuromuscular disorder.
Tremor During Exercise
In most cases, muscle tremors occurring after exercise are benign in nature and can involve the feet, legs, hands or arms. According to Dr. Pierre Rouizer, sports medicine physician at University of Massachusetts, exercise-induced dehydration -- which can result in electrolyte abnormalities -- can lead to muscle excitability and tremors until the chemical environment returns to baseline status. Dr. Rouizer also states that extreme physical stress can cause the muscle to tremor, as your body's capacity to handle the stress is insufficient.
Prevention
Muscle tremors related to chemical imbalances in the muscle environment can be remedied by replenishing electrolytes. According to "Men's Fitness" the key is to stay hydrated during exercise with sport drinks and electrolytes. Another tip is to incorporate a stretching period before and after workouts, as well as getting adequate rest in between workouts. Most importantly, do not overdo workouts and risk muscle injury.
Conclusion
If you are having muscle tremors that are not associated with exercise or not responding to stretching or adequate hydration, then it is important to have other possibilities investigated for this muscle abnormality. Genetic, skeletal, vascular or nerve causes will have to be evaluated and medical treatment may be warranted.
