Abstract

Do prekida rada u osnovnim vježbama dolazi kada najslabiji mišići koji sudjeluju u izvedbi vježbe dosegnu mišićni otkaz. U vježbama povlačenja su to najčešće mišići koji osiguravaju stisak šake, odnosno čvrst hvat. Kako bi se to izbjeglo, postoje različite metode i pomagala kojima se on može pojačati. Jedan od njih je i primjena fitnes gurtni. Stoga je cilj ovog rada bio utvrditi može li i u kojoj mjeri primjena fitnes gurtni prilikom izvedbe zgibova s vlastitom tjelesnom masom do otkaza... More povećati broj ponavljanja u odnosu na izvedbu zgibova bez primjene fitnes gurtni u jednoj seriji. Muška, tjelesno aktivna populacija (n = 10) izveli su maksimalan broj zgibova sa, odnosno bez primjene fitnes gurtni. Razlike su utvrđene t-testom za zavisne uzorke te je izračunata veličina porasta i veličina učinka. Rezultati t-testa pokazuju statistički značajnu razliku (t = 4,64; p = 0,001) u rezultatima izvođenja zgibova s primjenom (11,6 ± 3,95) i bez primjene gurtni (9,9 ± 4,12). Veličina porasta iznosi 17,17 %, dok veličina učinka iznosi 0,41. Dobiveni rezultati pokazuju da povećani broj ponavljanja izveden s gurtnama omogućuje povećanje ukupnog rada i vremena mišića pod napetošću, što može biti važno za razvoj jakosti i hipertrofije mišića. Stoga se preporuča dozirano korištenje gurtni na siguran način prema precizno definiranim ciljevima trenažnog procesa. Less

Abstract (english)

Interruption of work in basic exercises occurs when the weakest muscles participating in the exercise reach muscle failure. In pulling exercises, this most often pertains to grip flexor muscles, i.e. muscles that ensure a firm grip. In order to avoid this, there are different methods and aids that can amplify it. One of them is the use of fitness wrist straps. Thus, this paper aims to establish whether and to which extent the use of fitness wrist straps in the performance of bodyweight... More pull-ups to failure can increase the number of repetitions in relation to the performance of pull-ups without the use of fitness wrist straps in one set. Physically active male population (n = 10) performed the maximum number of pull-ups with or without the use of fitness straps. The differences were established in a t-test for dependent samples and the increase and effect sizes were calculated. The t-test results point to a statistically significant difference (t = 4.64; p = 0.001) in results of the performance of pullups with (11.6 ± 3.95) and without the use of fitness straps (9.9 ± 4.12). The increase size reaches 17.17%, whereas the effect size is 0.41. The results obtained show that the increased number of repetitions performed with straps allows for an increase in the total work and muscle time under tension, which can be important for the development of muscle strength and hypertophy. Therefore, a dosed use of fitness straps in a safe way in line with precisely defined objectives of a training process is recommended. Less
