Sprint carbohydrate loading slows performance

For more than 50 years, the athletes in sports where strength is used a training technique called carbohydrate loading. A recent study from South Africa shows that this technique sprint performance of cyclists (Journal of Applied Physiology, January 2006) has slowed.

Cyclists eating high fat or high carbohydrate diet for six days, followed by a diet rich in carbohydrates for one day and completed time trials on a bicycle. Then they ate the diet oppositefor six days by a diet rich in carbohydrates for one day and then repeat their lap. Diets do not have any influence on their time or power to 100 kilometers (62 miles), but the high-fat diet slowed their sprint performance over 1 km (0.6 miles).

Muscles get their energy from sugar and fat stored in muscles and is present in the muscles from the bloodstream. The limiting factor of how fast an endurance athlete, is the time needed to carry oxygen from theBlood in the lungs to the muscles. The muscles need oxygen to burn more fat burning sugar for energy. So, when a muscle begins its stored sugar called glycogen, is less efficient, hurts, is difficult to coordinate and slows down. Many previous studies have shown that it makes no difference what you eat a well-trained endurance athletes on the weekend before the race because the muscles store glycogen trained athletes when they reduce training for severalDays, regardless of what they eat. Any difference in the concentration of muscle and fat in muscle is not important during endurance competitions.

This study shows that hurts a high-fat diet before the sprint performance. A diet high in fat causes a higher proportion of muscle to burn fat. Using fat for energy requires more oxygen than carbohydrates do, and how fast you sprint 0.6 miles on the bike on how quickly you can supply oxygen limitedMuscles.
