Popis: Na nastavi TZK jedan od testova za provjeravanje motorièkih sposobnosti je podizanje trupa iz ležanja u sjed. Navedenim testom se provjerava repetitivna jakost trupa uèenika. Cilj je bio usporediti efikasnost dviju vrsta treninga: stabilizacijskih vježbi i pregiba trupa na test podizanje trupa iz ležanja u sjed kod uèenika sedmih razreda osnovne škole. Uzorak ispitanika saèinjavalo je 47 uèenika sedmih razreda osnovne škole. Razredi su sluèajnim odabirom podijeljeni na kontrolnu skupinu, koji su radili na tehnici trèanja (n=14), eksperimentalnu skupinu koja je provodila pregibe trupa (TRB, n=16) i eksperimentalnu skupinu koja je provodila stabilizacijske vježbe (STAB, n=17). Trenažni proces se odvijao u periodu od 6 tjedana. U tom periodu je provedeno 10 sati nastave TZK-a. Mjerenje je izvršeno na poèetku i nakon 6 tjedana trenažnog procesa. Prosjeèna razlika izmeðu rezultata u inicijalnom i finalnom mjerenju bila je najveæa kod uèenika koji su provodili dopunski trening stabilizacijskih vježbi (d=4,53), nešto manja kod kojima su sadržaj dopunskog treninga bile vježbe pregiba trupa (d=3,56), a najmanja kod uèenika u kontrolnoj grupi (0,29). Kod obje eksperimentalne skupine razlika izmeðu aritmetièke sredine u inicijalnom i finalnom stanju bila je statistièki znaèajna, dok kod uèenika kontrolne skupine navedena razlika nije dosegla razinu statistièke znaèajnosti. Stabilizacijske vježbe i pregibi trupa efikasno razvijaju repetitivnu jakost mišiæa prednje i boène strane trupa. Jakost mišiæa trupa bilo bi preporuèljivo razvijati stabilizacijskim vježbama, jer omoguæuju efikasno poboljšanje jakosti mišiæa trupa bez dugoroèno štetnih posljedica na kralježnicu.
Sit-up tests are used for measuring muscular endurance at physical education class. The aim of the study was to compare the efficiency of two types of the training process: core stabilization exercises and traditional trunk exercises on the sit-up test performed by the seventh grade elementary students. Sixty students began with the participation in the experimental program, and forty seven of them (age 13,7 ± 0,3 years, height 161.6 cm ± 7.01 cm, weight 52.55 kg ± 11.73 kg) completed the program. The classes were randomly divided into a control group which worked on a running technique (RTE) (N=14), an experimental group which performed traditional trunk exercises (TTE, N=16) and another experimental group which performed core stabilization exercizes (CSE, N=17). The training process lasted for six weeks. During that period physical education classes were held ten times. The initial measurement was done a week before the beginning of the treatment, and the final measurement a week after finishing the treatment. The average difference between the results in the initial and final measurement was greatest with the students who performed the additional training of core stabilization exercises (d=4.53), somewhat smaller with those who performed the additional training of traditional trunk exercises (d=3.56), and the smallest with students in the control group (d=0.29). In both experimental groups the difference between the mean in the initial and final state was statistically significant, while at students in the control group the aforementioned difference did not reach the level of statistical significance. Core stabilization exercises and traditional trunk exercises efficiently improve the muscular endurance of the trunk muscles. Trunk muscle strengthening is better recommended with core stabilization exercises, since they enable an efficient improvement of the muscular endurance without longterm detrimental effects on the spine.
