Moč in stabilnost trupa v kajaku in kanuju : magistrsko delo

Lenarčič, Jure (author), Rauter, Samo (mentor), Hadžić, Vedran (co-mentor)

Pomen moči in stabilnosti trupa v vsakdanu je vedno bolj izpostavljena tema. V magistrskem delu nas je zato zanimala pomembnost moči in stabilnosti trupa v kajaku in kanuju na divjih vodah v povezavi s tekmovalno uspešnostjo. Namen raziskave je bil ugotoviti moč povezanosti med maksimalno močjo stabilizatorjev trupa in tekmovalno uspešnostjo v kajaku in kanuju. Prav tako nas je zanimala moč povezanosti med vzdržljivostjo stabilizatorjev trupa in tekmovalno uspešnostjo v slalomu na divjih vodah, želeli smo ugotoviti tudi kakšna medmišična razmerja imajo tekmovalci ter ali so blizu teoretičnim vrednostim ali ne. Vzorec je zajemal 32 merjencev, ki so prihajali iz obeh disciplin, tako iz kajaka (22) kot iz kanuja (10) na divjih vodah. V raziskavo so bili zajeti predstavniki obeh spolov. Starost merjencev je bila 20.41±5.31. Testiranje smo izvedli v dveh delih. Na napravi Back Check proizvajalca dr. Wolff se je merila maksimalna moč fleksije in ekstenzije trupa, lateralnih odklonov levo in desno ter maksimalna sila potega in potiska. V drugem delu smo izvedli standardiziran test po McGillovi metodi za testiranje vzdržljivosti trupa. Pridobljeni rezultati so pokazali, da pri upogibalkah trupa ni statistične razlike v korelacijskem koeficientu med maksimalno močjo (p=0.098; r=0.289) oziroma vzdržljivostjo (p=0.222; r=-0.215) v povezavi s tekmovalno uspešnostjo, ima pa vzdržljivostni rezultat negativni predznak. Iztegovalke trupa so pri vzdržljivostnem delu testiranja dosegle višjo moč povezanosti (p=0.003; r=-0.409) s tekmovalnim uspehom kot pri testu maksimalne moči (p=0.079; r=0.305). Statistično pomembni rezultati so bili pri testu lateralnega odklona levo in desno v obeh segmentih – maksimalne moči (Desno: p=0.022; r=0.391, Levo: p=0.026; r=0.381) in vzdržljivosti (Desno: p=0.022; r=-0.391, Levo: p=0.011; r=-0.433). Pri testu maksimalne sile potega in potiska nismo zaznali skoraj nikakršne povezanosti s tekmovalno uspešnostjo v kajaku in kanuju na divjih vodah (r=0.155; r=0.201). Ugotovili smo, da razmerja stabilizatorjev trupa odstopajo od teoretičnih vrednosti za več kot 5 %.

• Title: The power and stability of the core in kayak and canoe

Abstract

The importance of strength in the stability of the torso in each day has been a growing topic of choice. In the Master's thesis we were therefore interested in the importance of strength in the stability of a kayak in a canoe in wild waters in relation to performance results. The purpose of the study was to determine the strength of the relationship between maximal core muscle strength and resultant performance in kayak and canoe. I was also interested in the power of the relationship between trunk muscle endurance and performance, and finding out what kind of inter-muscle relationships the competitors had, and whether or not they were close to theoretical values. The sample consisted of 32 investigators, both from their discipline, both from the kayak (22) and from the canoe (10). The survey included representatives of all genders. The subjects' age was 20.41 ± 5.31. The testing was performed in two parts. On the device Back Check dr. Wolff is the maximum strong flexion in torso extensions, left and right lateral deflections, and maximum pull force in the thrust. In the second part, we performed a standardized test according to McGill's method for testing the endurance of the hull. The results obtained showed that in the case of core bends and statistical differences in the correlation coefficient between maximum strenght (p = 0.098; r = 0.289), durability (p = 0.222; r = -0.215) may be related to competitive performance in order to have endurance results of negative signs. The trunk extensions thus achieved higher louver strength (p = 0.003; r = -0.40) in competitive endurance than the highest power (p = 0.079; r = 0.305). Statistically significant results, so that the left-to-right side-deviation scale had the highest strength (Right: p = 0.022; r = 0.391; Left: p = 0.026; r = 0.381) in endurance (Right: p = 0.022) ; r = -0.391, Left: p = 0.011; r = -0.433). At the highest possible thrust in the thrust, we did not detect any significant association with competitive performance in a wild-water canoe kayak (r = 0.155; r = 0.201). We found the hull stabilizer ratio to be more than 5 % of theoretical values.
