Abstract
Olimpijsko dizanje utega (OW) je sport koji zahtijeva veliku snagu jer sportaši moraju eksplozivno podići velik teret. Sastoji se od podizanja šipke trzajem te nabačajem i izbačajem. U treningu kondicijske pripreme često se koristi kao metoda za razvoj brzine i snage. Glavni je cilj ovog istraživanja bio utvrditi utjecaj četverotjedne trenažne intervencije olimpijskim dizačkim treningom na performanse brzine, agilnosti i snage kod mladih rekreativnih sportaša. Uzorak ispitanika sastojao se od 12 studenata kineziologije (prosječne dobi 23 godine) koji su pohađali kolegij Olimpijsko dizanje utega. Intervencija je trajala 4 tjedna s treninzima 3 puta tjedno na kojima su ispitanici radili vježbe olimpijskog dizanja bazirane na učenju tehnike i izvedbi pomoćnih dizačkih vježbi. Prije i nakon intervencije provedeno je testiranje brzine, agilnosti i snage. Za procjenu snage donjeg dijela tijela provedeni su testovi čučanj skok, skok s pripremom te skok u dubinu, a za procjenu snage gornjeg dijela tijela napravljen je test bacanja medicinke. Testovi sprinta na 5 i na 15 metara korišteni su za procjenu brzine i snage, dok je trčanje 20 jardi mjerilo nereaktivnu agilnost. Sve su varijable analizirane deskriptivnom statistikom te je proveden t-test za zavisne uzorke kako bi se utvrdio mogući utjecaj trenažne intervencije. Rezultati su pokazali napredak u skakačkim kapacitetima sa statistički značajnom razlikom zabilježenom jedino za skok s pripremom (CMJ, p>0.01). Snaga gornjeg dijela tijela i agilnost nisu pokazale značajne promjene dok je pad u sprint performansama uočen za obje mjerene varijable, sprint na 5 metara (S5, p>0.01) i sprint na 15 metara (S15, p>0.01). Dok su rezultati u varijablama skokova očekivani i u skladu s dosadašnjim znanstvenim spoznajama, rezultati u varijablama sprintova su pomalo zbunjujući. Moguće objašnjenje za to može se pronaći u činjenici da su ispitanici radili samo 4 tjedna zadatke koji biomehanički nisu slični strukturi pokreta sprinta. To može ukazivati da sportaši koji žele unaprijediti svoje eksplozivne kapacitete trebaju uvrstiti specifični sprint stimulans u svoj program treninga kao dodatak treningu olimpijskog dizanja. U budućim istraživanjima trebalo bi uključiti više varijabli i dulju trenažnu intervenciju.
Abstract (english)
Olympic weightlifting (OW) is sport with high strength and power demands where athletes need to explosively lift heavy weights. It is consisted of barbell lifting snatch and clean and jerk disciplines. In the strength and conditioning training, OW techniques are often used as a method for speed and power development. The aim of this study was to determine effects of 4-week OW training intervention on speed, agility and power performance among young recreational athletes. The sample of participants consisted of 12 Kinesiology students (aver- age 23 years old). They attended the Olympic Weightlifting course. The training intervention lasted 4 weeks and with 3 training sessions per week in which participants practiced OW training based on learning OW techniques and auxiliary lifts execution. Before and after the intervention, measurement was conducted and included power, speed and agility tests. Squat jump (SJ), countermovement jump (CMJ) and drop jump (DJ) were used to estimated lower body power and medicine ball throw (MBT) for upper body power. Sprinting on 5 meters (S5) and 15 meters (S15) were conducted as power and speed tests, while 20 yards test (20Y) measured nonreactive agility performance. All variables were descriptively analyzed and T-test for dependent samples was used to determine possible effects of training intervention. Results showed improvement in jumping capacities, with statistically significant difference noted only for CMJ (p>0.01). Upper body power and agility performance did not show any significant changes, while a decline in sprinting performance was found for both S5 (p>0.01) and S15 (p>0.01). While the results in jumping variables are expected and in accordance with current scientific knowledge, the results in sprint tests are somewhat con- fusing. Possible explanation for this can be found in the fact that the participants worked for four weeks the tasks that biomechanically are not similar to the structure of sprinting movement. This could suggest that athletes who want to improve their explosive speed capacities should include specific sprint stimuli in their training program in addition to OW training program. In the future, more variables and longer treatment duration need to be applied.
