energy systems in volley-ball
Transcript of energy systems in volley-ball
While in many sports, some energy systems are more predominant, all systems work together to produce and sustain your body while playing sport. The main three systems are the ATP-PC, Anaerobic Glycolysis and Aerobic Systems.
In volley-ball, games are played in 3 or 5 sets, and duration can range up to 3 hours. While other energy systems interplay into various volley-ball skills, the Aerobic System is the primary system that can sustain a player throughout the game. Aerobic energy can be restored between points, between sets, timeouts and substitutions.

The Anaerobic Glycolysis System
The Aerobic System
All three systems are used when playing volleyball. While the ATP-PC and Anaerobic Glycolysis system are being used constantly, the Aerobic is the dominant System being used.
The Aerobic System supplies the player with the energy to be sustained throughout the whole game. Volleyball is a dynamic game, and often can last for several hours. The energy release in the Aerobic system is slow and enables the player to expend energy more slowly. Your aerobic system will help with the recovery between points and the endurance you need for a long season.
The ATP-PC plays a huge role in volleyball. The basic elements of volleyball use the ATP-PC System; spiking, blocking and diving all require a powerful motion to push and jump. These motions only last for a short 2-5 seconds when moving into position then coming into contact with the ball.
The Anaerobic Glycolysis System is also another system heavily used in volleyball. In a series of plays, you will have a high intesity anaerobic burst followed by a recovery period. This could be in the form of a dig, set of a serve.
In volleyball, it is important to create a high level of anaerobic power quickly and then be able to recover and generate that same power again.
The ATP-PC System consists of adenosine triphosphate (ATP) and phosphocreatine (PC).
This energy system provides the body with immediate energy for a high intensity activity. At maximun power, your ATP-PC System will provide you wil 5seconds of maximum intesity exercise, before fatiguing. But at a lower intensity, can last for 10-15 seconds. This is a maximum exercise.
After the ATP-PC has expended its stores, the Anaerobic Glycolysis system takes over. Carbohydrates supply glucose that circulates in the blood or is stored in muscles and liver. These two types of glucose are then broken down to create ATP, this is called glycolysis.
The Anaerobic Glycolysis system produces more power than the Aerobic system, but less power then the ATP-PC system. It has a large store, but burns slower that ATP-PC, therefore does not fatigue as quickly.
The Aerobic System produces the most ATP but much more slowly, therefore the body can only use this fuel in low intensity exercises that can be sustained over a long period of time.
This system uses fats, carbohydrates and sometimes proteins to produce more ATP. The aerobic system goes through a three step process to produce ATP. This is Aerobic glycolysis, the Krebs cycle and the Electron transport chain.
Spiking in Volleyball rely's heavily on the ATP-PC System.
Jumping high in the the air, while simultaneously hitting the ball at great force requires significant power. The player must use momentum in a three step approach to reach the net, then use that to jump, pull their arm back then hir the ball over the net. This movement happens in around 3-4 seconds. The combination of speed and power when hitting the ball tell us it is the ATP-PC system working.
Blocking is similar to spiking as it also uses the ATP-PC System. When a player blocks a ball being hit over the net it requires a burst of power to jump high into the air, without touching the net or centre line. The movement requires explosive acceleration and force to lift your body into the air.
Diving is a skill less used in volleyball, but still requires a large amount of technique to complete. A a singular movement, it also uses the ATP-PC System, as the dive is a 'last resort' power to keep the ball from hitting the ground and subsequently lasts around 2 seconds. Power is applied to reach a speed, to be able to get to the ball.
I also want to acknowledge that while movements such as setting, digging, spiking, blocking and diving apply the ATP-PC System as singular movements. In a rally, where several of these skills would be applied, the body would use its Anaerobic-Glycolytic System to sustain an adequate amound of power, until the rally ends and the body can rest and replenish its ATP stores.
