少d糖係咪少d加路里,少左能量囉?
Not really. If you take a look at the back of the gel, most of them only have 100 to 110 cal. The sugar inside the gel are simple sugars (mono- and disaccharides) which break down and get digested very easily, which means the energy goes away really fast. When doing endurance activites, it is better to to fuel your body with complex carbohydrates (polysaccharides) which allow your digestive system to rapidly and efficiently process a greater volume of calories, providing steady energy for longer endurance. Good source of complex carbohydrates are vegetables, whole grain breads, oatmeal, legumes, brown rice and wheat pasta. For HKers, of course a few bowls of white rice or noodles. This is why you do 'carbo loading' the night before the marathon. Sorry if I am getting a bit complicated here. |
