Carbohydrate Loading - Assignment Example Under normal circumstances the energy requirement of the body is met by carbohydrate and fats however, for athletes undergoing strenuous training the main source of energy is carbohydrates which help in the working out of muscles. An athlete is at the peak of his performance as long as his body has enough carbohydrate to supply to his muscles in use. Once this storage of carbohydrates depletes and is completely exhausted, the body starts to use up the fats to provide energy. Therefore, it is crucial for athletes, especially those who are engaged in strenuous sports like marathon, to have enough carbohydrate storage during the entire run and this is where carbohydrate loading comes in. Glycogen Supercompensation is the scientific terminology for Carbohydrate Loading. It is the process through which the glycogen level in the muscles maybe increased by 60% through proper training and diet. Thus, the increased levels of glycogen reserves in the muscles mean that the athlete can now perform his best for a longer period of time without fatiguing his muscles and performing poorly. All carbohydrate loading methods have two stages- Carbohydrate depletion stage and Carbohydrate replenishment stage. I have selected the second method of carbohydrate loading and I shall provide a day-to-day guide. This method stretches over a week and must be started 1 week before the sports event. Like all other methods, this method also has two stages, i.e. the depletion of carbohydrates during which glycogen synthesizing enzymes are stimulated and the increasing of glycogen in particular muscles. It must be remembered that carbohydrate foods with low glycemic index must be taken because they stimulate the enzyme-glycogen synthetase, which is responsible for glycogen storage. Hydrating the body is important because for each gram of stored glycogen there must be 3-4grams of stored water. Two

Cellular Mobile Communications - Essay Example However, the question â€Å"how cell phone works† emerges in the minds of people (Brain, Tyson and Layton). The main intention of this research is to discuss and provide a detailed analysis of the new cellular telephony technology, mobile communication principles, cellular system architectures, and cellular system components that participate in establishing cellular mobile communications. Brain, Tyson, & Layton (2009) stated that it is a really interesting fact that cellular mobile communication technology is an advanced form of radio. In other words, it can be said that new mobile phones are very complicated radio; however it is not a radio. In addition, Alexander Graham Bell invented the present telephone system in 1876, and Nikolai Tesla invented the wireless communication technology and radio in 1880s. However, it was simply natural that telephone and wireless communication technology have been combined to presently offer us a great technology and communication advantage (Brain, Tyson and Layton; Hagn and Markwitz; Turban, Leidner and McLean). The fundamentals of mobile and cellular technology employ the traditional radio spectrum using the mobile system operators for offering the mobile services.  However, the mobile technology spectrum is normally recognized as a scarce resource.   In addition, it has conventionally been shared by different industries, such as mobile communications, broadcasting and the military. In 1993, at the World Radio Conference (WRC), the radio spectrum sharing intended for 2G mobile were decided based upon on expected expansion at the time.   In addition, at the World Radio Conference 2000, the declarations was passed regarding the enhancement in the spectrum and capacity to be employed for 3G, by permitting the utilization of present 2G radio spectrum blocks intended for 3G mobile technologies as well as offering and allocating 3G spectrum to an higher limit of 3GHz (ITU; Gupta and
