Povzetek:The present study examined whether differences in the heart rate recovery following flywheel exercise cessation were associated with differences in maximal oxygen uptake (V%O2 max.), age and sex in trained adults. Eleven men (age range 22%49 years, V%O2 max.%=%43.6%%%7.6 mL kg min%1) and ten women (age range 20%53 years, V%O2 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.
