The key nutritional issues in sports nutrition for women include calcium and iron. Weight control and eating disorders are also concerns of sports nutrition for women. You need these nutrients for their body to perform properly. There still has been no scientific explanation for this, but it is in truth that women are very conscious of weight. Athletes who have high calorie intakes of about 5,000 to 6,000 kcal/day may achieve 200% or more of the RDA for some vitamins and minerals just from foods they eat. Despite this fact, most of the athletes who are concerned with sports nutrition take supplements to boost performance. While vitamin and mineral deficiencies impair physical performance, research indicates that supplementation of a nutritionally adequate sports diet does not improve physical work capacity, endurance, oxygen consumption, cardiovascular function, muscle strength, or resistance to fatigue. Years after, antioxidant supplementation became a norm in the world of sports nutrition. Now, researchers are also beginning to understand that muscle damage is a more complex subject. It is difficult to assess free radical damage in athletes and it has been found out that large amounts of antioxidant nutrients may actually cause cellular damage and impair performance. Another is the Creatine, which is also for sports nutrition and muscle growth but it also involves bodybuilding this time; HCA or Garcinia Cambogia, for losing weight and suppressing your appetite; and last but certainly not the least, Vitamin B-12, this one is for overall health and nutrition. So what more could you ask for? Our body can't function well without the two important polyunsaturated fats: the linoleic and the alpha-linoleic acid. - Cod liver oil, a fish essential oil for sports nutrition. Cod liver oil is rich in Vitamin A and D. This two-in-one essential oil is on the list of athletes' favorite essential oil for sports nutrition. People also have this misconception that what is tasty is good for your health. It is really hard to resist unhealthy food because of their availability on the market. Media also advertise more on unhealthy junk foods rather than healthy ones. Unhealthy food may be a reason for us to be fat. If you want to keep healthy, you must first get rid of unwanted fats and be fit as possible.
