Merjenje srčne frekvence in s tem spremljanje srčno-žilnega odziva na telesno dejavnost nam lahko daje koristne informacije o delovanju avtonomnega živčnega sistema pri ljudeh po možganski kapi. Namen: Ugotoviti razlike v odzivu srčne frekvence, ocenah občutenega napora in njuno povezanost med različnimi funkcijskimi testi pred, po 4-tedenski vadbi in 10 tednov po vadbi pri ljudeh v kroničnem obdobju po možganski kapi. Metode: V raziskavi je sodelovalo devet preiskovancev, starih od 30 do 80 let, v kroničnem obdobju po možganski kapi. V vseh treh ocenjevanjih so preiskovanci izvedli test hoje na 10 metrov (10MWT), 6-minutni test hoje (6MWT), test hoje po stopnicah, test petih vstajanj (5TSTS) in 2-minutni test korakanja (2MST). Srčno frekvenco z merilcem Polar (H10, Polar, Finska) smo merili med vsakim testom in še šest minut po njem. Poleg tega so preiskovanci po koncu vsakega testa ocenili občutenje napora na 15-stopenjski Borgovi lestvici. Za analizo srčne frekvence smo uporabili začetno, končno, najvišjo in povprečno vrednost ter okrevanje srčne frekvence, ki smo jih pretvorili v deleže preiskovančeve izračunane maksimalne srčne frekvence. Rezultati: Med testoma 10MWT in 5TSTS so bile vrednosti končne, najvišje in povprečne vrednosti ter vrednosti okrevanja srčne frekvence nižje kot med 6MWT in 2MST, med testom hoje po stopnicah, 6MWT in 2MST pa ni bilo statistično značilnih razlik. Podobno so bile ocene občutenega napora po 10MWT, testu hoje po stopnicah in 5TSTS nižje kot po 6MWT in 2MST, medtem ko med 6MWT in 2MST ni bilo razlik. Povezanosti med funkcijskimi sposobnostmi preiskovancev, srčno frekvenco in oceno občutenega napora nismo ugotovili pri nobenem ocenjevanju. Zaključek: Med izvedenimi testi obstajajo razlike v odzivu srčne frekvence in ocenami RPE. Kot najbolj zahtevna za srčno-žilni sistem sta se izkazala 6MWT in 2MST. Podobno zahteven je bil tudi test hoje po stopnicah, sledi 5TSTS, najmanj zahteven pa je bil test hitrosti hoje. Med funkcijskimi sposobnostmi preiskovancev, srčno frekvenco in oceno občutenega napora nismo ugotovili povezanosti. V prihodnosti so potrebne raziskave na večjem vzorcu preiskovancev, v katerih bi preučevali odzive avtonomnega živčevja na različno zahtevne telesne dejavnosti.

• Title: Heart rate response during walking tests, five times sit to stand test and two-minute step test in people after stroke : master thesis

Abstract

Introduction: Measuring the heart rate during physical activity and thus monitoring the cardiovascular response can give us valuable information about the functioning of the autonomic nervous system among people after stroke. Purpose: To identify the differences in heart rate response and rating of perceived exertion, their mutual relationship during various functional tests before, after 4 weeks of exercise, and after 10 weeks of exercise in people in the chronic post-stroke period. Methods: The study involved nine subjects, aged between 30 and 80, in the chronic period after stroke. In all three assessments, subjects performed 10 meter walk test (10MWT), six-minute walk test (6MWT), stair climb test, five times sit to stand test (5TSTS) and 2 minute step test (2MST). The heart rate was recorded by using a heart rate monitor (H10, Polar, Finland) during every test and for six more minutes after the completion of every test. In addition, subjects rated perceived exertion on a 15-point Borg scale at the end of each test. For the analysis of heart rate, we used the initial, final, highest and average value and heart rate recovery, which were converted into proportions of the subjects’ calculated maximum heart rate. Results: During the 10MWT and 5TSTS, the final, highest, mean, and heart rate recovery values were lower than during 6MWT and 2MST, while there were no statistically significant differences among the 6MWT, the 2MST and the stair climb test. Similarly, perceived exertion were lower after 10MWT, stair climb test and 5TSTS than after 6MWT and 2MST, while there were no major differences between 6MWT and 2MST. Moreover, no association between subjects’ functional abilities, heart rate, and perceived exertion was found in any of the assessments. Conclusion: Among the tests, there are differences in heart rate response in RPE estimates. 6MWT and 2MST were the most demanding for the cardiovascular system. The stair climb test was similarly demanding, followed by 5TSTS, and the least demanding was the walking speed test. Future studies should consider a larger sample of subjects to examine the responses of the autonomic nervus system to differently demanding physical activities.
