Not only athletes and sportsmen, but also common individuals have to deal with tiredness, and also less energy. It is hard to expend your energy in a short spurt and then have to go through the whole day listlessly. If you are a sports person, then it is even worse. You start your race or game with a burst of energy and then are not able to last out because you are tired. People confuse big muscles and a toned frame for a storehouse of inexhaustible supply of energy. It simply is not true. When a common person gets tired, he makes mistakes like miss a turn to his work place, athletes cannot respond quickly and make mistakes that costs them the game. Fatigue is, putting it simply; when the body cannot produce energy required to do ones work. Why does one get tired and have no energy? Science has developed enough to give us a good idea of the entire process, which is complex. It involves use of oxygen and the nutrients in our body and the elements.

Our muscles use a chemical compound which every sports person is familiar with called adenosine triphosphate called ATP to generate energy. This chemical makes the muscles contract and is produced through normal metabolic processes, during which the nutrients in our body are broken down into sugars. This sugar gets either used immediately or converted into glycogen and stored as fats for future use. ATP is used by muscles for that intense spurt of energy that is required since ancient times for split second reactions, for fleeing and in the actual world for that last minute speed that wins the race. For long term energy use we need endurance that is sourced from nutrients stored in body cells. This sourcing involves oxygen. When you lift a heavy bag, you use ATP and not oxygen, but when you are walking a long distance your body uses fats, proteins, carbohydrates and these need to be broken down to be absorbed and metabolized. This needs oxygen. So, naturally, low levels of oxygen lead to low energy and fatigue.

Hence increasing energy will require sufficient levels of oxygen in the body. It is also very important to have the right nutrients the body needs to break down to get the right amount of ATP required. Athletes know this and have all the elements, the fats and the carbohydrates in place so that they have a sufficient supply of energy. Energy in both forms is essential but, as a sportsperson will tell you, increasing energy is all about being able to give the muscles ATP when they need it.

One important element used by athletes and increasingly being adopted by people wanting to lose weight and getting fitter is creatine phosphate. This is now sold as a supplement too. It is naturally made by your body in the pancreas, liver and kidney with the help of amino acids. Creatine phosphate is very useful in increasing energy in the body. You could take the supplement or you could also eat well, consult your nutritionist who will guide you on the right sort of diet for your metabolism. Every one has unique needs, and if you are just a weekend player or someone who works out on alternate days, you may not need many supplements. A natural and balanced diet is the best for you. However, if you are planning to build your body or are taking up a game professionally, you need all the help you get to get your energy requirements.
