Namen naloge je bil ugotoviti povezavo med izhodnimi spremenljivkami (največja teoretična sila (F_0), največja teoretična hitrost (v_0) in največja izhodna moč (P_max)) odnosa sila-hitrost-moč s splošnim in specifičnim testom agilnosti ter hitrosti spremembe smeri. V raziskavo je bilo vključenih 39 karateistov slovenske in avstrijske članske reprezentance (starost: 19,3 ± 4,1 let; višina: 173,2 ± 8,2 m; telesna masa: 65,4 ± 10,6 kg). Za vrednotenje agilnosti smo izvedli T-test in specifičen karate test na kratki (K-KR) in dolgi razdalji (K-DR) ter hitrost spremembe smeri pri 90° (HSS90°) in 180° (HSS180°). K-KR, K-DR, HSS90 in HSS180 so bili vrednoteni z dominantno (D) in nedominantno (ND) nogo. Simetrijski indeks je pokazal rahlo asimetričnost (1,9 % - 8,2 %). Skladnost med preferenčnostjo in dominantnostjo je bila zmerna (κ = 0,43-0,52). Za vrednotenje jakosti in moči smo izvedli navpični skok z nasprotnim gibanjem (SNG) z dodanimi bremeni in polčep pri masni inercijski obremenitvi (MIO). Pri SNG so dosegali višje vrednosti (F_0 = 29,9 ± 4,3 N; v_0 = 4,7 ± 1,5 m/s; P_max = 34,5 ± 7,4 W/kg) v primerjavi z MIO (F_0 = 27,0 ± 4,3 N/kg; v_0 = 2,0 ± 0,4 m/s; P_max = 13,3 ± 2,1 W/kg). Povezave med SNG-F_0 ter HSS90, HSS180 in T-test so šibke do zmerne (r = -0,39 do -0,58; p < 0,05), med SNG-v_0 in HSS180 ter T-testom sta šibki (r = 0,32-0,37; p < 0,05), med MIO-P_maxin K-KR je šibka (r = -0,37; p < 0,05). Z večstopenjsko multiplo regresijo smo preučevali napovedno moč F_0, v_0 in P_max, pri napovedovanju testov agilnosti ter hitrosti spremembe smeri. Največji delež variance je znašal za HSS180 (R^2 = 33,5 %) in T-test (R^2 = 27,7 %), malo manj za HSS90 (R^2 = 15,4 %) in K-KR (R^2 = 13,8 %). Najpomembnejše spoznanje raziskave je relativna nizka povezanost med izhodnimi spremenljivkami odnosa sila-hitrost-moč ter izbranimi testi agilnosti in hitrosti spremembe smeri.

Relationship between force-velocity-power profiles obtained by two different types of overload and their relation to agility and change of direction performance |
Sekundarni povzetek: |
The purpose of the study was to determine the relationship between output variables (teoretical maximal force (F_0), theoretical maximal velocity (v_0) and maximal power output (P_max)) of force-velocity-power relationship with general and specific agility and change of direction tests. The study included 39 karate athletes from Slovenian and Austrian national teams (age: 19,3 ± 4,1 years; height: 173,2 ± 8,2 m; weight: 65,4 ± 10,6 kg). To evaluate agility we performed a T-test and a specific karate test at short (K-SD) and long distance (K-LD) and the change of direction at 90° (COD90°) and 180° (COD180°). K-SD, K-LD, COD90 and COD180 were evaluated with dominant (D) and nondominant (ND) leg. The symmetric index showed a slight asymmetry (1,9 % - 8,2 %). The level of agreement between preference and dominance was moderate (κ = 0,43-0,52). To evaluate strength and power, we performed a vertical counter movement jump (CMJ) with additional loads and a flywheel squat (FW). Greater values were achieved for CMJ (F_0 = 29,9 ± 4,3 N; v_0 = 4,7 ± 1,5 m/s; P_max = 34,5 ± 7,4 W/kg) compared to FW (F_0 = 27,0 ± 4,3 N/kg; v_0 = 2,0 ± 0,4 m/s; P_max = 13,3 ± 2,1 W/kg). The relationship between CMJ-F_0 and COD90, COD180 and T-test were weak to moderate (r = -0,39 to -0,58; p < 0,05), between CMJ-v_0, COD180 and T-test were weak (r = 0,32–0,37; p < 0,05), among FW-P_max and K-SD was also weak (r = -0,37; p < 0,05). The stepwise multiple regression was used to study the predictive power of F_0, v_0 and P_max, when predicting agility tests and change of direction tests. Best predictors were COD180 (R^2 = 33,5 %) and T-test (R^2 = 27,7 %), slightly less COD90 (R^2 = 15,4 %) and K-SD (R^2 = 13,8 %). The most important finding of the research is relatively low correlation between the output variables of the force-velocity-power relationship, agility and change of direction performance. |
