Bananas are considered to be a good source of energy and are prized by recreational and endurance athletes alike. Due to bananas being a good source of potassium, minerals, vitamins and other nutrients, along with their portability, bananas are popular with cyclists, hikers and other athletes, according to researchers at Appalachian State University's Human Performance Lab.
Researchers have determined that bananas are as beneficial as most sports drinks at helping replenish athletes during and after a workout. In addition to potassium, bananas have a high amount of antioxidants, fiber and Vitamin B6, which are critical to an athlete's nutrition. Also, the sugars in bananas are better for the body than those found in sports drinks.
