Running, biking, and swimming are high-intensity activities. For the endurance athlete, there are many types of energy supplements. Athletes generally use these portable, convenient supplements every 30-50 minutes during races or events that are more than 60 minutes in length.
Energy supplements contain a combination of proteins, carbohydrates, sodium, electrolytes, potassium, caffeine, and fats to burn energy. There are two kinds of carbohydrates in energy supplements—simple carbohydrates of sucrose, glucose, and fructose and complex carbohydrates such as glucose polymers and maltodextrins.
Supplements delay muscular fatigue, raise your blood sugar, enhance performance. You may also feel a psychological boost in as quickly as five minutes after consuming energy supplements. Energy supplements can provide an athlete with energy during events that require extreme endurance.
