Development of Agility and Reactivity in Tennis : Undergraduate Thesis

Tenis je kompleksna sportska aktivnost obilježava velik broj različitih tehnika kretanja koje se pretežno izvode maksimalnom brzinom u dugom vremenskom razdoblju. Kretanja se sastoje od ponovljenih startova, ubrzanja i usporavanja, te brzih promjena pravca kretanja od kojih su ishod udarca i taktička komponenta u direktnoj zavisnosti. Iz navedenog razloga najvažnije i najviše zastupljene motoričke sposobnosti su upravo startna brzina i ubrzanje te brza promjena pravca kretanja. U literaturi koja se bavi kondicijskom pripremom sportaša u posljednje se vrijeme brzina, agilnost i eksplozivna snaga mogu pronaći u zajedničkom kontekstu. Zajednički naziv za ove tri motoričke sposobnosti je brzinsko-eksplozivna svojstva, odnosno SAQ (speed, agility and quickness). Ove se sposobnosti tretiraju zajednički, zbog nekoliko zajedničkih karakteristika: koriste iste energetske resurse, na sličan način podražuju živčani sustav, imaju zajedničke faktore o kojima ovisi razina pojedine sposobnosti i potrebno je zadovoljiti iste preduvjete za intenzivan trening pojedine motoričke sposobnosti. Također se smatra da sportaši s izraženijim brzinsko-eksplozivnim svojstvima lakše kontroliraju svoje tijelo u urgentnim trenažnim i natjecateljskim situacijama što uvelike pridonosi prevenciji ozljeda.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
