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
