The impact of musical rhythm on exertion at running

V nalogi smo preučevali, ali sočasno poslušanje glasbe med tekom s submaksimalno intenzivnostjo spremeni strukturo tekaškega koraka, razdaljo in hitrost teka ter napor. V raziskavi je sodelovalo deset preizkušancev: pet oseb moškega in pet oseb ženskega spola povprečne starosti 31 (12,4) let, povprečne teže 77,5 (13,8) kg in povprečne telesne višine 176,2 (6,8) cm. Preizkušanci so opravil 20-minutni tek, ki je bil razdeljen na štiri odseke, ki so trajali 5 minut. V treh odsekih so merjenci poslušali glasbo s tempom 130, 160 in 190 udarcev v minuti, eden izmed odsekov teka pa je bil izveden brez sočasnega poslušanja glasbe. Odseki teka s sočasnim poslušanjem glasbe in brez so bili naključno porazdeljeni. Rezultati raziskave so pokazali, da sočasno poslušanje glasbe s počasnim (130 ud/min) in srednjim tempom (160 ud/min) ne spremeni strukture tekaškega koraka, razdalje in hitrosti ter napora med tekom, medtem ko sočasno poslušanje glasbe s hitrim tempom 190 ud/min poveča razdaljo, hitrost in napor med tekom. Frekvenca korakov se med sočasnim poslušanjem glasbe s hitrim tempom ni spremenila, zato lahko predpostavimo, da so bili večja hitrost teka, razdalja in napor posledica daljše dolžine korakov preizkušancev. Sočasno poslušanje glasbe s tempom 190 ud/min najverjetneje vpliva na centralne (mišična aktivacija) in periferne dejavnike (kontraktilni mehanizem), ki so pomembni za razvoj mišične sile.The goal of this thesis was to examine whether listening to music while running at sub maximal effort has an impact on the gait, distance and speed and effort at running. Ten volunteers were included in the study, five male and five female. Their average age was 31 (12,4) years, average weight 77,5 (13,8) kg and average height 176,2 (6,8) cm. Subjects performed a 20 minutes long run divided into four segments, each segment 5 minutes long. In three of those segments subjects simultaneously ran and listened to music with tempos of 130, 160 and 190 beats per minute. In one of the segments no music was played. Segments with music of different tempos were set in random order. Results have shown that listening to slower (130 bpm) and mid tempo (160 bpm) music while running does not affect gait cycle, speed, distance or effort at running. However, listening to the fast tempo music (190 bpm) increases distance, speed and effort. Cadence was also not affected when subjects listened to the musictherefore we can presume that the increase of speed, distance and effort derived from increased gait length of runners. Simultaneously listening to fast music (190 bpm) while running most likely affects central (muscular activation) and peripheral factors (contractile mechanism), which are important for muscle force development
