Exercise is a wonderful way to keep in shape and increase energy levels, but some people find that physical exertion leaves behind fatigue and exhaustion. According to a 1997 study published in "Research in Nursing and Health," exercise has long been used to battle chronic fatigue syndrome with great promise. This evidence might leave you wondering why you still suffer from decreased energy levels once your workout is over.
Exercise
As you exercise, your body is eliminating energy through calorie metabolism. Physical exertion takes your daily caloric intake and uses it for energy to keep your heart rate up and your mind and body in peak condition. According to Dr. Mauro DiPasquale, your body only provides a certain amount of energy based on your dietary intake. Once this energy is used up, your body slows down, preparing for rest. Excessive exercise is the main cause of this energy expenditure, with your body telling you it is time to stop. Pushing your personal limits will only speed up your tired feeling.
Nutrition
Your body requires a set amount of calories through the major food groups. Carbohydrates found in breads, pastas and potatoes are required to keep your energy levels up and your blood glucose levels stable. Cambridge University's publication "Proceedings of the Nutrition Society," says carbohydrates are a main staple used by athletes during endurance training in preparation for such sports as sprinting and marathons. Proteins are also an essential part of preventing exercise-induced fatigue. Proteins are required to build muscle and provide adequate energy, thus prompting many weight lifters to increase protein intake to bulk up and provide alertness.
What to Do
Treating your symptoms once you have determined that there are no underlying health issues will restore your energy levels and optimize your workout. Drink plenty of water throughout the day and electrolyte beverages before and after exercise, suggests DiPasquale. As you sweat, your body loses important nutrients such as potassium and trace minerals. Wear light clothing when exercising to allow your skin to breathe. Heavy fabrics induce heavy sweating, thus speeding up dehydration risk and raising your body's core temperature. Pay attention to your body and stop exercising if necessary. Pushing yourself to the point of exhaustion through excess exercise will cause more harm than good. Lastly, eat a healthy diet consisting of proteins, vitamins, minerals and carbohydrates to ensure plenty of energy-boosting properties.
Considerations
Fatigue after exercise can be attributed to diet and overexertion, but in some cases, it can also be a sign of underlying medical conditions. If your efforts do not pay off, it is time to consult your physician. Chronic fatigue induced by exercise or daily regular activity can be a sign of diabetes, cardiovascular disease, stress and iron deficiency. It is important to ask questions that give you a clearer understanding of how fatigue works and how you are able to get your life back on track should any health conditions arise.
