Introduction

Science Different types of sport require different types of energy systems: There are three separate energy systems required involve in physical activities. Different sports may require the development of one of these systems or all three. With knowledge of these different energy systems this enables training to be specific to your needs. All working muscles require ATP (adenosine triphosphate), this is a compound which has a central molecule linked by three high energy phosphate bonds. Energy is provided by breaking one of these bonds, the constant supply of ATP provides instant energy, allowing us to move on demand. But there is only a limited amount of ATP that exists in muscle cells, there is about 3seconds wotrh of maximum activity. ...read more.

Middle

This system requires a series of chemical reaction to occur and produces lactic acid as a breakdown product. It lasts longer, up to a few minutes, but lactic acid build up in muscle inhibits efficient contraction and causes the familiar "burning" feeling in a near exhausted muscle. Interval training, short near maximal bursts initiates this system, and trains your body to tolerate lactic acid build-up and to develop this mechanism. This system is used in a sprint in cycling and may be used for intense periods in a game like rugby. A problem with the lactic acid system is that the lactic acid needs to be removed and metabolized by the body, procedures which both consume energy. ...read more.

Conclusion

Some sports may concentrate on one system, and actively avoid using the other, typically the aerobic endurance athlete avoiding the lactic acid system. Other sports may require more flexible energy sources, a racing cyclist needs an excellent aerobic base, but needs to be able to sprint briefly and repeatedly using the anaerobic system. For this individual the training should mimic this and utilize "interval" techniques. Again, sports involving primarily strength or a sudden effort may require strength and speed training of the muscles involved. This develops the anaerobic systems primarily. At the end of the day however, all of this can be summed up by the word "specific". To be successful you training must be "specific", and mimic the sport in which you wish to succeed. Training that is not "specific" and develops inappropriate energy systems may be actually detrimental to performance in your chosen sport. ...read more.
