It also contributes to efficient walking and reducing the risk of falls. Maintaining balance is achieved by activity of interconnected systems: muscular, sensory, skeletal and central controlling mechanisms. The complexity of balance controlling processes and the many aspects with which we describe balance makes it difficult to determine uniform assessment of the balance tasks intensity. By prescribing balance training only with training frequency, type of training and its duration, the exact outcome cannot be predicted. Among the more promising approaches, with which we could comprehensively assess the intensity of balance tasks or their difficulty is by monitoring the pupil dilation or pupillometry. Pupillometry is an indirect measure of brain functions and a reflection of cognitive processes. Maintaining balance represents a cognitive load that is dependent on the difficulty of the balance task, age and the efficiency of the individual's postural control system. Based on these, pupillometry could gather more indepth information on the involvement of the cognitive processes in performing the balance task. This could provide an objective assessment of the balance tasks difficulty and, consequently, an objective measure of its intensitySposobnost ohranjanja ravnotežja je pomembna za ohranjanje neodvisnega življenja in opravljanja vsakodnevnih dejavnosti. Pomembna je tudi za izvajanje učinkovite hoje ter zmanjšanje tveganja za padce. Za ohranjanje ravnotežja skrbijo številni procesi, ki se medsebojno povezujejo: mišični, senzorični, skeletni in centralni upravljalni mehanizmi. Zapletenost teh procesov in številni vidiki s katerimi opisujemo ravnotežje otežujejo določanje enotne ocene intenzivnosti nalog ohranjanja ravnotežja. Če vadbo ravnotežja predpisujemo samo s frekvenco vadbe, tipom vadbe in njenim trajanjem, ne moramo napovedati njenega izida. Med obetavnejše pristope, s katerim bi lahko celovito ocenili intenzivnost ravnotežnih nalog oziroma njihovo zahtevnost, sodi spremljanje dilatacijskih lastnosti očesne zenice ali pupilometrija. Pupilometrija je posredno merilo delovanja možganskih funkcij in odraz kognitivnih procesov. Ker ohranjanje ravnotežja predstavlja kognitivno obremenitev, ki je odvisna od zahtevnosti naloge uravnavanja ravnotežja, starosti in od sposobnosti posameznikovega sistema za uravnavanje ravnotežja, bi lahko s pomočjo pupilometrije izmerili kognitivni napor, ki ga predstavlja opravljanje ravnotežne naloge. S tem bi lahko pridobili objektivno oceno zahtevnosti ravnotežne naloge in posledično objektivno mero njene intenzivnostiTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za šport
