Ponovljivost in kakovost izvedbe ravnotežne naloge po ogrevanju s sočasno izvedbo gibalne in kognitivne naloge : magistrsko delo

Bestijanič, Tajda (author), Tomažin, Katja (mentor)

Cilji magistrske naloge so bili ugotoviti ali sta kakovost in ponovljivost tandemske stoje z zaprtimi očmi odvisni od načina ogrevanja. Zato je bilo v raziskavo vključenih 11 študentk. Meritve so opravile štiri krat (poskusna meritev, kontrolna meritev, ogrevanje samo z gibalno nalogo in ogrevanje z dvojno nalogo). Po izbranem ogrevanju je sledilo izvajanje tandemske stoje z zaprtimi očmi na tenziometrijski plošči, kjer smo spremljali skupno hitrost, hitrost v anterio-posteriorni in medio-lateralni smeri oprijemališča sile reakcije podlage ter amplitudo oprijemališča sile reakcije podlage v anterio-posteriorni in medio-lateralni smeri. Rezultati so pokazali, da je ogrevanje z dvojno nalogo poslabšalo kakovost (izvedbo) tandemske stoje z zaprtimi očmi, pa čeprav je bila intenzivnost stopanja nižja od predvidene (60-70% FSU rezerve). Napor med ogrevanjem samo z gibalno nalogo v primerjavi z dvojno nalogo se ni spremenil statistično značilno. Ponovljivost izbranih parametrov je ostala po različnih ogrevanjih podobna. Zato lahko zaključimo, da dodatna kognitivna naloga v ogrevanju ni omogočila učinkovitejšega nadzora in upravljanja ravnotežja med tandemsko stojo, saj so se vrednosti izbranih parametrov hitrosti in dveh amplitud povečali (t.j. višja hitrost in višja amplituda gibanja OSRP). Potrebno je sicer poudariti, da so bili potenciacijski učinki ogrevanja z dvojno nalogo lahko zabrisani, z nadomeščanjem energetskega dolga, ki je lahko nastal zaradi manj stabilnega in manj ekonomičnega stopanja zaradi sočasnega izvajanja kognitivne naloge.

• Title: Repeatability and quality of balance exercise after simultaneous warm-up with motor and cognitive task

Abstract

The main purpose of this master was to establish whether the quality and repeatability of tandem stance with eyes closed dependent on warm–up protocol. Therefore this research includes 11 students. The measurements were completed four times (trial, control measurement, warm–up with motor task and dual warm–up). After specific warm – up protocol, the student complete tandem stance on force platform, where we monitored total velocity, sway velocity in anterior-posterior and medial-lateral direction center of pressure, amplitude center of pressure in anterior-posterior and medial-lateral direction. The results showed that dual-task warm–up protocol decreases quality od tandem stance with eyes closed, even though the motor task intensity was lower than expected (60-70% HR max). An effort in motor task warm–up in comparison to the dual task warm–up was not different statistically significant. Repeatability of chosen parameters was after different warm–up protocol similar. That's why we can conclude that additional cognitive task in warm–up does not enable efficient control and management of balance in tandem stance because the values of chosen parameters velocity and two amplitudes were increased (higher velocity and the amplitude of COP). We must otherwise underline that potential effects of dual warm–up could be confused, by replacing energy debt which occurred after less stable and economical stepping because of the dual cognitive task.
