According to the Daily Mail, sports drinks such as Powerade are possibly harmful to the body because they are high in calories, and this contributes to weight gain. While sports drinks are marketed as being necessary to stave off dehydration when exercising, there are other options which provide hydration during a workout with fewer calories.
Water is the best way to hydrate the body after a loss of fluids, according to the Mayo Clinic. However, in the case of 60 or more minutes of physical activity, drinks such as Powerade are beneficial in quickly replacing lost fluids and electrolytes. Powerade also functions to provide a boost of energy during training because of the included carbohydrates in the form of glucose, sucrose and fructose.
According to WebMD, Powerade and fruit juice both provide the same benefits to replace lost electrolytes during a workout. To reduce the amount of sugar and calories consumed, it is recommended to dilute Powerade with water or to pour it into a thermos filled with ice before a workout.
According to The Daily Mail, the over-consumption of sports drinks contributes to hypernatremia. This is a deadly condition that causes the brain cells to swell due to over-hydration.
