Tennis is categorized as a complex sporting activity. It is characterised by a large number of different techniques of movement that are mostly performed by maximum speed in a long period of time. Movements consist of re-starting, acceleration and slowing downand rapid changes of direction, of which the outcome of the stroke and the tactical component are in direct dependencies. For this reason the most important and most represented motor skills are starting speed and acceleration as well as quick change of direction. Recently, the literature dealing with the fitness preparation of athletes has found speed, agility and explosive power in a common context. The common name for these three motor skills is the explosive property, SAQ (speed, agility and quickness). These abilities are treated jointly because of several common characteristics: they use the same energy resources, similarly stimulate the nervous system, have common factors that depend on the level of a particular ability and need to satisfy the same prerequisites for intensive training of a particular motor skills. Athletes with more pronounced speed-explosive properties are also thought to have easier control over their bodies in emergency training and competitive situations, which greatly contributes to injury prevention.
