when the person being under the research was standing on a single and two legs and making jumps on a single and two legs. DURING SINGLE- AND TWO-LEG STANCE AND SINGLE- AND TWO-LEG JUMPING
The materials and methods: The test-retest method was used TEZ LEPSZY BEZOKOLICZNIK in the assessment of the repetitiveness. SILA... BYLA MIERZONA DWA RAZY, Z 7-DNIOWA PRZERWA, W GRUPIE 24 males having no HISTORY OF injuries of the

, the fact stated during the interview (T-R group)
took part twice in the process of ground reaction forces measurement separated with seven days-break from one another. The
research EXPERIMENT was conducted using AN MTD Balance force platform for one-footed and two-footed standing, and for one-footed/two footed jumping. The second
trial ATTEMPT was recorded by
another A DIFFERENT investigator.
During the statistical analysis
process, INVOLVED OBLICZENIE the interclass correlation coefficient (ICC)
was calculated.
Results: The ICC coefficient, calculated on the basis of the component merit CO MA ZNACZYC MERIT? of the vertical force during
the two-footed standing, resulted=SPOWODOWALA respectively in 0,91 KROPKA ZAMIAST PRZECINKA W ULAMKACH, CHYBA WIESZ? for the lower right limb and 0,94 for the left limb.
In case ofFOR one-foot standing, the ICC coefficient for right and left limb resulted in 0,98 and 0,99 respectively. During the two-footed jumping trial we recorded the ICC
results WARTOSCI ranging from 0,44 to 0,49 for THE LEFT AND RIGHT lower

Conclussion: The component vertical ground reaction forces' measures using MTD Balance system WIESZ, ZE COS TRZEBA POPRAWIAC DO TEGO MIEJSCA
while DURING one- and two-footed standing, are characterized
with BY high
ly-leveled repetitiveness, even while being conducted by different researchers. In case of measuring the component vertical ground reaction forces in the jumping phase by different researchers, the repetitiveness level decreases, in comparison to the standing phase. The repetitiveness level during one-footed jumps was decent. The lowest repetitiveness level of the component vertical ground reaction forces - the satisfactory one - is determined by the two-footed jump W JAKI SPOSOB RODZAJ SKAANIA MA USTALAC POZIOM POWTARZALNOSCI?
