ACUTE EFFECT OF BALANCE EXERCISES ON VERTICAL JUMP

Uobičajeno, vježbe balansa su se koristile u rehabilitaciji ozljeda zglobova i kod posturalnih deficita. Danas se, osim u svrhu rehabilitacije i prevencije, koristi za poboljšanje performansi sportaša, pogotovo mišićne snage. Cilj ovog rada bio je istražiti utječu li vježbe balansa odmah nakon njihove primjene na vertikalni skok, u smislu poboljšanja ili suprotno. Koncept istraživanja sastojao se od zagrijavanja, vertikalnog skoka, vježbi balansa te ponovnog vertikalnog skoka, tim redoslijedom. Uzorak se sastojao od 24 zdrava ispitanika između 18 i 22 godine koji se bave nekom aktivnošću najmanje 3 puta tjedno. Šest ispitanika bilo je u kontrolnoj grupi, 10 ispitanika u grupi koja je radila vježbe balansa ukupno 4 minute i osam ispitanika u grupi koja je vježbe balansa radila ukupno 8 minuta. Visina dosega vertikalnog skoka mjerila se na centimetarskoj vrpci (cm) dosegom ruke što je snimljeno usporenom snimkom te su rezultati obrađeni statističkim računicama. Rezultati pokazuju da razlika između visine vertikalnog skoka prije i nakon vježbi balansa nije značajna. Usporedba pojedinačnih rezultata je mješovita, sa poboljšanjima u skoku i suprotno, ali širina uzorka nije dovoljna da se rezultat smatra statistički značajnim. Fiziološka shvaćanja mogu do jedne granice objasniti različitost rezultata, no za statističku značajnost i razumijevanje o ovoj širokoj temi potrebno je još kvalitetnijih i metodički bolje napravljenih istraživanja.Usually, balance exercises have been used in the rehabilitation of joint injuries and in postural deficits. Today, except for the purpose of rehabilitation and prevention, it is used to improve performance of athletes, especially muscle strength. The aim of this study was to investigate whether balance exercises immediately after their application affect the vertical jump, in terms of improvement or vice versa. The research concept consisted of warming up, vertical jump, balance exercises, and again vertical jump, respectively. The testing sample consisted of 24 healthy subjects between 18 and 22 years of age engaged in some activity at least 3 times a week. Six subjects were in the control group, 10 subjects in the group doing balance exercises for a total of 4 minutes, and eight subjects in the group doing balance exercises for a total of 8 minutes. The height of the vertical jump range was measured on a centimeter tape (cm) with the reach of the hand, which was recorded in slow motion, and the results were processed by statistical calculations. The results show that the difference between the height of the vertical jump before and after the balance exercises is not significant. The comparison of individual results is mixed, with improvements in the jump and vice versa, but the width of the sample is not sufficient for the result to be considered statistically significant. Physiological understandings can explain the diversity of results to some extent, but for statistical significance and understanding of this broad topic, more quality and methodologically better research is needed
