Bars higher in fats and protein are made for athletes needing extra supplements before and after high-intensity workouts. They are also used by weight lifters and others wishing to build body mass. Since many bars are high in fiber, which acts like a sponge in the body, it's important to have them with water. And though an energy bar may be healthier than a candy bar, it does contain calories. People eating energy bars while trying to lose weight should be sure to keep track of their caloric intake, Vinci says.
Gels are one of the newest types of sports available.
Easily carried and quickly consumed, they provide a burst of carbohydrates that can be easily digested. Vinci points out that gels are made for use by high-endurance athletes and are not designed as a snack food. Keeping the body well hydrated is essential to staying in top shape. Sports drinks, fortified with carbohydrates and electrolytes, were first developed for long distance athletes those performing for more than 90 minutes. Vinci explains that while the average athlete doesn't need the additives found in sports drinks, they do need to consume water.
