The Performance Demands of Netball and the Methods of analys
Netball is an interval-type game. Players perform repeated short bursts of vigorous activity (work periods) interspersed with relief intervals, which include movements such as slow jogging, walking, and passive defence. Most intense work periods in netball are less than five seconds. In fact, the average sprint times of skilled netball players during a game have been shown to be less than 1.5 seconds (Steele and Chad, 1992).The predominant energy source required for short bursts of intense effort lasting less than 10 seconds is provided from the breakdown of high-energy phosphates, adenosine triphosphate (ATP) and creatine phosphate (CP). These substances, stored in muscles, provide a rapidly available energy source without need for oxygen to provide fuel. High-energy phosphates are the predominant fuel source used in netball to enable players to perform characteristic explosive sprints, jumps, and leaps intermittently throughout a match. The ATP-CP energy system, however, cannot support all - out efforts longer than 5 to 10 seconds. Fortunately for netball players, ATP-CP stores depleted after maximal efforts are rapidly replenished during relief intervals, with half the energy source available for use 30 seconds fol
Tactics are very important and although each group of players must combine successfully e.g. Goal Attack with Goal Shooter also each group must also form a link with the next group e.g. Centre court players with defence players Ways of moving the ball up court should be worked out so that the ball travels accurately and smoothly towards the goal, using all the players. Apart from energy systems, additional physical demands are required to enhance netball performance. For example, adequate abdominal muscular strength is required to maintain correct torso alignment during skills such as shooting and landing from a jump. Adequate abdominal muscular strength also aids in preventing lower back pain, a common problem among netball players caused by repeated impact loading with hard court surfaces. Like any sport, the final result of each game can determine how well the team played. The most effective method of analysis would be through video feedback of the game. Video analysis provides the players and the coach immediate feedback, allowing them to focus on their errors and breakdown any specific movements of set plays that are not going to plan e.g. centre passes. Coaches use video feedback to deconstruct and analyse personal technique and technique of others.
