The World of Sports Nutrition
Advancements in medicine and an increase in capitalism in the world as well as other factors all contributed to the development of the field of sports nutrition.
As scientists learned more and more about our bodies and the optimum level of strength and physical fitness they can harbor, businessmen jumped the gun and manufactured products and services that actually help athletes meet these optimum levels. The media joined in the ruckus and published materials leading to the promotion of both the scientific and the commercial side of the field.
Sports nutrition has been changing through the years around the world. It’s not just that the topics are different – the emphasis and approach have also changed.
The Importance of Nutritional Supplements in Your Daily Routine
Life is often so busy and stressful that it is impossible not to suffer from nutritional deficiency. To live a healthy life, you need to have a balanced diet. A balanced diet is one that has a balanced amount of all the macro nutrients (proteins, carbohydrates, and fats). Nowadays, nobody has enough time to maintain a balanced diet.
Nutritional supplements are products that provide a balance of vitamins, minerals, herbs, and nutrients. Nutritional supplements are consumed for many reasons. They can be taken to improve overall body health, to boost the immune system, to reduce the risk of catching diseases, to improve the health and performance of bodybuilders and athletes, and to help children with irregular food intake patterns maintain a healthy body weight. Nutritional supplements are very popular throughout the world and in the United States alone, they account for about a $19.8 billion market value.
All About Sports Nutrition
Carbohydrates and Exercise
Carbohydrates are your main source of fuel when you exercise – you cannot perform well without them. When carbohydrates are eaten they are broken down into glucose which enters the bloodstream. The pancreas then releases a hormone called insulin, which takes the glucose out of the blood and into the cells where it is used as energy. Any excess glucose is stored in the muscles and liver as glycogen ready to be used when needed. On average, the body has enough glycogen to fuel between 90 – 180 minutes of endurance activity. The higher the intensity, the faster the glycogen stores will be depleted. Low muscle glycogen stores can lead to reduced training intensity and early fatigue.
It is important to keep your glycogen stores stocked up by eating and drinking at the right times, and also by eating the right types of carbohydrates. Refined carbohydrates such as pasta, Jaffa cakes and chocolate have all been heavily processed and are high in sugar but very low in fibre and nutrients such as the B vitamins, zinc, magnesium and chromium. This means they release glucose quickly into the bloodstream, which causes a rapid surge of energy followed by a fast drop as insulin works to bring your sugar levels back down. This can leave you feeling tired and can affect your performance. See below for what to eat before, during and after exercise.
