Pros and Cons of Energy Gels

energy gels for runningCarbohydrates are condensed into gels that provide energy for exercise and promote recovery and these are convenient to consume and the energy provided is immediate. Energy gels are used by endurance athletes such as cyclists and runners. While exercising for hours, these athletes need to consume fuel for energy and food can be clumsy and too filling. Drinking too many sports drinks can cause cramping and heaviness. These energy gels are also named endurance gels or sports gels after the population it caters for.

The main ingredient in these gels is carbohydrates, but there are also other nutrients that are added to delay muscular fatigue, provide energy and raise blood sugar levels. These gels are easily digested because there is no added protein or fat and the average gel contains about 100 calories. The carbohydrates consist of sugar and maltodextrins to provide quick release energy and the gels are a dehydrated form of sports drinks. Gels arose after sports drinks were invented and they are a different form of energy. Gels are consumed fifteen minutes before starting and every 30-45 minutes during exercise to sustain the athlete until the end of the event. Usually the energy gels are only consumed in longer events lasting more than two hours and about two gels can be taken per hour, but this is dependant on the product, runner’s size and the distance. To avoid dehydration, it is recommended that energy gel be followed with water.  Many gels can be diluted in water to make it more drinkable and less thick, but this can be time consuming and clumsy on the run. Popular brands include e-Gel, Gu and Powerbar and flavours range from cappuccino to berry.
