Sports and Energy Bars
0% read · 2 min left
Sports bars are a convenient emergency energy source but are calorie-dense, often low in quality protein and fiber, and should not replace whole foods.
Detail
One of the most popular fads in sports nutrition is the sports bar (also known as the energy bar). Packages promise an edge over the competition or high-octane fuel for optimal performance. Revenue from sports bars sold in 1996 exceeded $100 million, a figure projected to triple by the year 2000 (Harovitz 1997).
Boost or bust? The greatest attribute of sports bars is their convenience as an energy source and food substitute. The bars range in calories from 120 to 465, though most weigh in at 200 to 250. Because they are so calorie-dense, they counteract the goal of weight or fat loss and are not indicated for clients who train less than 90 minutes per day. Many sports bars are heavily fortified with vitamins and minerals, but this fortification provides no nutritional advantage over whole foods and cannot make up for a poor diet.
Recommendations: There is a place for sports bars, especially for athletes seeking a quick boost or when food is unavailable. Bars higher in protein and fat (PR Bar, Balance Bar, 40-30-30 Bar) are best for between-meal snacks because they stay in the stomach longer than high-carbohydrate bars, giving a feeling of satiety. Clients trying to gain weight do best with higher-calorie bars (Met Rx Bar, Steel Bar, No Holds Bar). A high-carbohydrate bar (Clif Bar, Power Bar, Tiger Sport) is best suited for elite endurance training exceeding 90 to 120 minutes. Sports bars are generally low in high-quality protein, fiber, and phytochemicals, and should not replace whole foods — especially the fruits and vegetables needed daily. They are not magic bullets for improved performance.
