20.500.12556/DiRROS-14112 Independent infuence of age on heart rate recovery after flywheel exercise in trained men and women The present study examined whether differences in the heart rate recovery following flywheel exercise cessation were associated with differences in maximal oxygen uptake (VO2 max.), age and sex in trained adults. Eleven men (age range 22-49 years, VO2 max.=43.6 +/- 7.6 mL kg min -1) and ten women (age range 20-53 years, VO2 max.=38.0 +/- 5.7 mL kg min%1) were randomly assigned to complete a squat-exercise on the flywheel ergometer set at three different moments of inertia, while their cardiovascular responses were continuously monitored. During the flywheel exercise the mean arterial pressure rose by ~35 to 40% (p=.001), and the increment was more robust in men than women. The cardiac index was two-fold greater across both sexes compared to the baseline (p=.001), while the rise in heart rate (~144 bpm) was more pronounced in women to compensate for their load-dependent stroke index decline (p=.001). The load-independent time-course changes in heart rate recovery markers were comparable between the sexes. When these indicators were pooled, a stepwise regression revealed age as the only relevant predictor of both fast and slow components of the heart rate recovery (~30 of the shared variance explained, p=.014). The present data suggest that the heart rate recovery declines with age, irrespective of sex, or well-preserved cardiorespiratory fitness in moderately-trained adults. training exercise Yo-Yo exercise flywheel heart rate variability total peripheral conductance oxygen uptake kinetics telesna aktivnost telesne vaje Yo-Yo vadba vztrajnik variabilnost srčne frekvence periferna prevodnost ožilja kinetika porabe kisika true false true Angleški jezik Ni določen © Te Author(s) 2021 Neznano 2021-06-11 09:37:02 2021-06-11 09:37:03 2022-08-19 03:39:03 0000-00-00 00:00:00 2021 0 0 Nasl. z nasl. zaslona; Opis vira z dne 10. 6. 2021; Soavtorji: Nandu Goswami, Vladimir Ivančev, Zoran Valić in Boštjan Šimunič; Članek št. 12011; str. 1-11 ǂart. no. ǂ12011 Vol. 11 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 796.012:612.6 2045-2322 10.1038/s41598-021-91565-w 66598403 ZRSKP_Zubac_Damir_i2021.pdf ZRSKP_Zubac_Damir_i2021.pdf 1 66D401CA44F951ACE5C7764AFF3884D0 d9648c2bf8ac6568074018df464b28094ea1c4f52cbe84246510de7287af655a 961c1f79-17b6-11ed-b6b8-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=17484 https://www.nature.com/articles/s41598-021-91565-w.pdf 1 https://dirros.openscience.si/Dokument.php?lang=slv&id=17481 https://doi.org/10.1038/s41598-021-91565-w 1 https://dirros.openscience.si/Dokument.php?lang=slv&id=20236 Znanstveno-raziskovalno središče Koper / Centro di Ricerche Scientifiche Capodistria 0 0 0
