Uvod: Kardiorespiratorna vzdržljivost je pomemben kazalnik telesnega zdravja. Nanaša se na sposobnost srca in pljuč, da med telesno dejavnostjo dovajata kisik delujočim mišicam. Ocenjujemo jo z vrednostjo maksimalne porabe kisika, in sicer z maksimalnmi in submaksimalnimi aerobnimi testi. Med slednje spadata tudi šestminutni test hoje in Queen's College test stopanja. Namen: Namen raziskave je bil preveriti skladnost šestminutnega testa hoje in Queen's College testa stopanja pri določanju vrednosti maksimalne porabe kisika pri zdravih mladih odraslih osebah. Metode dela: V raziskavo so bili vključeni zdravi mladi odrasli, obeh spolov, stari od 20 do 25 let. Pred testiranjem so bile z Vprašalnikom o zdravstvenem stanju in telesni dejavnosti preverjene morebitne kontraindikacije za sodelovanje v raziskavi, zatem so preiskovanci v istem dnevu opravili oba testa. Iz dobljenih rezultatov testov je bil s pomočjo linearnih enačb izračunan približek vrednosti maksimalne porabe kisika pri obeh testih, s pomočjo Borgove 15-stopenjske lestvice pa je bil ocenjen še zaznani napor ob izvedbi posameznega testa. Testa sta bila primerjana glede na izračunan približek vrednosti maksimalne porabe kisika in glede na oceno zaznanega napora ob izvedbi testa. Rezultati: V raziskavo je bilo vključenih 32 oseb, 16 moških in 16 žensk (povprečna starost 22,4 (1,5 let)). Povprečna maksimalna poraba kisika je pri šestminutnem testu hoje znašala 44,15 (4,84 ml/kg/min), pri Queen's College test stopanja pa 42,15 (8,34 ml/kg/min). Povprečna razlika maksimalne porabe kisika med testoma (2,01 (6,74 ml/kg/min)) ni presegla vnaprej določene največje sprejemljive razlike 3,00 ml/kg/min. Povprečna razlika med zaznanim naporom ob izvedbi šestminutnega testa hoje in ob izvedbi Queen's College testa stopanja je znašala 2,19 (0,69). Testa se glede na oceno zaznanega napora statistično značilno razlikujeta. Razprava in zaključek: Kljub primerljivosti izračuna približka maksimalne porabe kisika med testoma je bilo ugotovljeno, da sta testa zamenljiva pri določanju vrednosti maksimalne porabe kisika le za moške, za ženske tega ne moremo trditi. V nadaljnjih raziskavah bi bilo smiselno povečati vzorec ter zajeti preiskovance različnih starostnih skupin in preveriti, ali sta testa res zamenljiva pri določanju vrednosti maksimalne porabe kisika le za moške.

Izvleček

Introduction: Cardiorespiratory endurance is an important indicator of physical health. It refers to the ability of the heart and lungs to deliver oxygen to working muscles during physical activity. It is measured with maximum oxygen uptake using maximal and submaximal aerobic tests. The latter include the 6-minute walk test and the Queen's College step test. Purpose: The purpose of this study was to assess whether an agreement exists between VO2max estimated from six-minute walk test and Queen's College step test in healthy young adults. Methods: The participants were healthy young adults of both sexes, aged between 20 and 25 years. Prior to testing, the Health and physical activity questionnaire was used to check for possible contraindications to participation in the study, and then both tests were performed on the same day. From the results of the tests, linear equations were used to approximate the maximum oxygen uptake for the 6-minute walk test and the Queen's College step test, and a 15-point Borg rating of perceived exertion scale was used to estimate the perceived exertion during each test. The tests were compared according to the calculated approximation of the value of the maximum oxygen uptake and according to the estimation of the perceived exertion at the time of the test. Results: The study included 32 subjects, 16 men and 16 women (mean age 22.4 (1.5 years)). The mean maximum oxygen uptake in the 6-minute walk test was 44,15 (4,84 ml/kg/min) and in the Queen's College step test was 42,15 (8,34 ml/kg/min). The mean difference maximum oxygen uptake between tests (2.01 (6.74 ml/kg/min)) did not exceed maximum acceptable difference of 3,00 ml/kg/min decided a priori. The mean difference in perceived exertion score between the 6-minute walk test and the Queen's College step test was 2.19 (0.69). The two tests are statistically significantly different in terms of perceived exertion rating. Discussion and conclusion: Although the approximated calculation showed comparability in the values of maximum oxygen uptake between the two tests, it was observed that the tests are interchangeable for determining maximum oxygen uptake values only for men, but the same cannot be said for women. In future studies, it would be useful to increase the sample size and include subjects of different age groups and check whether the two tests are really interchangeable in determining maximum oxygen uptake values for men only.
