Badminton requires a high level of energy to quickly move around the court, deliver effective shots and sustain a match. Knowing how this energy is generated is crucial.All other things being equal, the player with more stamina will most likely win a match in baminton. This is because while good stroke skills, effective shot placements and fast footwork are important characteristics in a good player, fitness is necessary in executing and sustaining these movements for the duration of a match. As a player's energy is depleted, his or her ability to perform also goes down.
The Nature of Badminton:
Unlike marathon or jogging, moves in badminton vary from standing to slow and sudden actions. Predominantly, however, badminton involves a lot of sudden, short and explosive movements, such as doing a jump smash, pedaling back to return a clear shot to the back of the court, lunging forward to catch a drop shot to the net, jumping toward the net to deliver a net kill shot, engaging in a back and forth exchange of drive shots, etc. Badminton, therefore, is more of an anaerobic sport, which is characterized by short, sudden burst of high intensity actions, especially in men's doubles. A good example of an anaerobic sport is a 100-meter sprint which, for top Olympic sprinters, lasts only under 10 seconds. Other sports, such as marathon, are considered aerobic sports because they involve continuous movements at more or less the same pace and are appropriately called steady state activities. However, considering the duration of a badminton match, which could last from 30 minutes to an hour, it also has aerobic elements which means it would also require sustained endurance. So the more accurate description would be that badminton is both an aerobic and anaerobic sport, with emphasis on the anaerobic aspect.
The Three Energy Systems:
There are three energy systems responsible for supplying energy to the body that every serious badminton player should know. These are the (1) ATP-PC or phosphagen energy system, (2) glycolytic or lactic acid energy system and the (3) oxygen energy system. The oxygen energy system is activated during aerobic exercises, while the ATP-PC and glycolytic energy systems are used during anaerobic exercises. Anaerobic Energy System:
The ATP-PC or phosphagen energy system and glycolytic or lactic acid energy system are grouped under the anaerobic energy system. Anaerobic simply means without oxygen, as opposed to aerobic, which means with oxygen. Therefore, the phosphagen and glycolytic systems do not rely on oxygen for the production of energy needed by the muscles. ATP is said to be the currency of energy because it is responsible in producing the energy needed to fuel muscle activity; without ATP the muscles cannot contract or produce movement.
ATP-PC Energy System:
The ATP-PC energy system relies on the ATP stored in the muscles, which is found in small quantities only at any given time. When food taken by the body is broken down through the digestive process, ATP is produced and stored in the muscle cells. This energy system, however, is limited in that it can only fuel muscle activity for a short duration, usually lasting between six to eight seconds. Some place the duration at 10 seconds. . Because of the speed with which it supplies energy to the muscles and and the short duration it lasts, it is the energy source in short burst, high intensity actions, such as in the execution of a smash shot, a quick lunge to catch a drop shot, or in most badminton rallies which usually lasts for only a few seconds.
If an activity lasts for more than eight or 10 seconds, another energy system kicks in: the glycolytic or lactic acid energy system. The ATP-PC and glycolytic energy systems are most ideal sources of energy for anaerobic sports like badminton because they...
