It would be expected that a player with good concentric strength and power can apply more force to the ground with each leg, accelerate faster and as a result is quicker.Īnthropometry – should be tested anyway with regard to weight and body fat. Leg muscle qualities – might build the foundation of COD performance (and also injury prevention. Although it was mentioned that COD and straight line speed seemed to be distinct qualities (5, 18), we feel that straight sprinting speed will affect COD performance. Straight line sprinting speed – sprinting is always needed in football. Technique – we feel that technique (foot planting during cutting, low center of gravity etc.) is important however the testing is rather complicated, most of the time based on qualitative methods and therefore somewhat hard to accomplish. The factors were: Technique, Straight sprinting speed, Leg muscle qualities (reactive strength, concentric strength and power, left-right muscle imbalances)Īnthropometry – only small body of research investigated the connection between anthropometry and COD, however it seems logical that players with higher lean leg muscle mass are more likely to be faster than players with higher amount of fat.Īs it can be observed at least the first three components are very important and trainable and therefore important to test. Agility itself on the other hand incorporates perceptual and decision-making processes and can be seen as a response to a stimulus and therefore as an open skill (and not pre-planned).ĭepending on the goal, testing and training (for agility) needs to incorporate the two mentioned things (perception and decision-making), or not (for COD).Ĭhange of direction: elaborated on the qualities of change of direction. The difference between the two was seen that change of direction (pre-planned and therefore a close-skill) was thought to be part of agility. Therefore we feel we need to define the two terms first before we go into testing. “Quickness” and “cutting” are words that were also to be found in the literature with regard to agility and change of direction. What is the change of direction in football?Īs usual we start with elaborating on terminology in order to get a clear understanding.įrom a sport science perspective there seems to be a debate about the definition of agility – see references below and somehow for change of direction (COD) as well.
