Abstract

Brojna istraživanja pokazuju da sportaši zanemaruju važnost euhidracije prilikom započinjanja tjelesne aktivnosti što se može negativno odraziti na izvedbu. Cilj ovog istraživanja je bio procijeniti utjecaj stupnja hidracije rukometaša prije početka tjelesne aktivnosti na njihovu sportsku izvedbu. Profesionalni rukometaši (n=14, dob 24,4 ± 4,5 godina) podijeljeni su u dvije grupe od 7 igrača od kojih je jedna grupa bila kontrolna. Obje grupe ispitanika odradile su četiri treninga istog intenziteta tijekom četiri dana. Prvoj grupi svakog dana procijenjen je stupanj hidracije prema Armstrongovoj skali za boju urina te je s obzirom na procjenu svaki ispitanik korigirao stupanj hidracije pijenjem varijabilne količine vode unutar četiri sata prije tjelesne aktivnosti. Nakon tjelesne aktivnosti utvrdila se samoprocjena napora tjelesne aktivnosti pomoću Borgove skale za određivanje percepcije napora. Rezultati su pokazali da je grupa koja je konzumirala vodu prije tjelesne aktivnosti bolje podnijela tu aktivnost (12,5 ± 1,9) od grupe koja nije konzumirala vodu prije tjelesne aktivnosti (14,0 ± 2,0) prema Borgovoj skali. Ovo istraživanje ukazuje da euhidracija rukometaša prije tjelesne aktivnosti može povoljno utjecati na njihovu sportsku izvedbu.

Abstract (english)

Many studies show that athletes ignore the importance of euhydration when starting physical activity which can have a negative effect on performance. The purpose of this study was to evaluate effects of the level of hydration before the start of physical activity on performance in handball players. Professional handball players (n=14, age 24,4 ± 4,5 years) were divided into two groups of 7 players of which one group was control. Both groups did four trainings of the same intensity during four days. Level of hydration was measured every day for the first group with Armstrong urine color chart and each player was supposed to drink specific amount of water depending on their level of hydration up to four hours before phsyical activity. After phsyical activity self-assessment of effort was established with Borg's rating of perceived exertion scale. Results showed that the group that consumed water before physical activity performed better (12.5 ± 1.9) then the group that did not consume water prior to physical activity (14.0 ± 2.0). This study indicates that euhydration in handball players before physical activity may lead to their better performance during the activity.
