Namen naše raziskave je bil preveriti ponovljivost meritev srčne frekvence s senzorjem Polar H10 ter ponovljivost ocen občutenega napora po 15-stopenjski Borgovi lestvici za oceno občutenega napora med telesno dejavnostjo. Poleg ponovljivosti meritev srčne frekvence ter ponovljivosti ocen občutenega napora, smo preverili tudi stopnjo korelacije (Spearmanov koeficient) med ocenami občutenega napora in izmerjeno srčno frekvenco med telesno dejavnostjo. V raziskavo je bilo vključenih 21 zdravih mladih odraslih preiskovancev (15 žensk ter šest moških), ki so v laboratoriju opravili obremenitveno testiranje s cikloergometrom pri naraščajoči intenzivnosti telesne dejavnosti, antropometrijo ter meritve telesne sestave z metodo bioelektrične impedančne analize. Začetna delovna obremenitev pri cikloergometriji je bila 1 kp, katero smo na vsake dve minuti povečali za 0,5 kp oz. 25 W. Obremenitveno testiranje se je zaključilo, ko je preiskovanec dosegel srčno frekvenco 160 utripov na minuto. Z izračunom koeficienta intraklasne korelacije (ang. intraclass corelation coeficient; ICC) smo potrdili, da je ponovljivost meritev srčne frekvence odlična (ICC = 0,98) ter da je ponovljivost ocen občutenega napora visoka (ICC = 0,90). Povezanost med ocenami občutenega napora in izmerjeno srčno frekvenco je zelo visoka (ro = 0,81). Zaključimo lahko, da je pri zdravih mladih preiskovancih uporaba senzorja Polar H10 za merjenje srčne frekvence ustrezna ter da je Borgova lestvica verodostojno merilo intenzivnosti telesne dejavnosti.

• Title: Repeatability of heart rate measurements and assessments of effort sensitivity during physical activity

Abstract

The purpose of our study was to verify the repeatability of heart rate measurements with the sensor Polar H10 and the repeatability of assessments of effort sensitivity with 15-point Borg rating scale of perceived exertion during physical activity. In addition to the repeatability of heart rate measurements and the repeatability of assessments of effort sensitivity, we also verify the stage of correlation (Spearman’s coefficient) between the assessments of effort sensitivity and measured heart rate during physical activity. The study included 21 healthy young adult subjects (15 women and 6 men) who participated in exercise test with a cycloergometer in increasing intensity of physical activity, anthropometry and measurements of body composition using the method of bioelectrical impedance analysis. The initial working load in cycloergometry was 1 kp, which was increased every two minutes for 0.5 kp i.e. 25 W. Test was completed when the subject reached a heart rate of 160 beats per minute. By calculating the intraclass correlation coefficient (ICC), we proved that the repeatability of heart rate measurements is excellent (ICC = 0.98) and that the repeatability of assessments of effort sensitivity is high (ICC = 0.90). Correlation between the assessments of effort sensitivity and measured heart rate is very high (ro = 0.81). We can conclude that in healthy young subjects, the use of the Polar H10 heart rate sensor is appropriate and that the Borg scale is a credible measure of physical activity intensity.
