“…This is consistent with our first hypothesis, i.e., that low PaO 2 level may delay post-exercise HRR (Ba et al, 2009; Mahe et al, 2011). There was however no clear correlation between HRR 60s and PaO 2 level (Table 2).…”

“…Differences in exercise intensity (supramaximal vs. maximal or submaximal) can also explain these discrepancies. The supramaximal exercise used in the present study (i.e., all-out 20-s sprint) was likely to elicit a greater anaerobic glycolytic participation than a constant submaximal (present Sub data and those from Mahe et al (2011)) and/or incremental exercise (eliciting 90% of subjects’ maximal HR; Ba et al, 2009). Compared with these latter lower-intensity exercises, the greater metabolite accumulation in the blood observed after Supra was likely associated with an almost-maximal autonomic activity perturbation (Buchheit et al, 2007a); the superimposed hypoxic stimulation was therefore unlikely to further impair cardiac autonomic activity (Figure 4).…”

“…While this can be seen as paradoxical with respect to observations from previous studies (Ba et al, 2009; Mahe et al, 2011), care should be taken when comparing different populations (unhealthy vs. healthy) and the nature/cause (physiological hypoxemia vs. simulated hypoxic exposure) of blood hypoxemia. Differences in exercise intensity (supramaximal vs. maximal or submaximal) can also explain these discrepancies.…”

“…There was however no clear correlation between HRR 60s and PaO 2 level (Table 2). The possible relationship between PaO 2 and HRR 60s is likely population-dependent, with correlations evident in unhealthy individuals (who experience very low PaO 2 levels), but not for healthy individuals (Ba et al, 2009; Mahe et al, 2011; Table 2). For instance, Ba et al (2009) reported a reduced HRR in patients presenting high blood hypoxemia, but not in healthy subjects.…”

In this study we assessed the effect of acute hypoxia on post-exercise parasympathetic reactivation inferred from heart rate (HR) recovery (HRR) and HR variability (HRV) indices. Ten healthy males participated in this study. Following 10 min of seated rest, participants performed 5 min of submaximal running at the speed associated with the first ventilatory threshold (Sub) followed by a 20-s all-out supramaximal sprint (Supra). Both Sub and Supra runs were immediately followed by 15 min of seated passive recovery. The resting and exercise sequence were performed in both normoxia (N) and normobaric hypoxia (H; FiO2 = 15.4%). HRR indices (e.g., heart beats recovered in the first minute after exercise cessation, HRR60s) and vagal-related HRV indices [i.e., natural logarithm of the square root of the mean of the sum of the squared differences between adjacent normal R–R intervals (Ln rMSSD)] were calculated for both conditions. Difference in the changes between N and H for all HR-derived indices were also calculated for both Sub and Supra. HRR60s was greater in N compared with H following Sub only (60 ± 14 vs. 52 ± 19 beats min−1, P = 0.016). Ln rMSSD was greater in N compared with H (post Sub: 3.60 ± 0.45 vs. 3.28 ± 0.44 ms in N and H, respectively, and post Supra: 2.66 ± 0.54 vs. 2.65 ± 0.63 ms, main condition effect P = 0.02). When comparing the difference in the changes, hypoxia decreased HRR60s (−14.3% ± 17.2 vs. 5.2% ± 19.3; following Sub and Supra, respectively; P = 0.03) and Ln rMSSD (−8.6% ± 7.0 vs. 2.0% ± 13.3, following Sub and Supra, respectively; P = 0.08, Cohen’s effect size = 0.62) more following Sub than Supra. While hypoxia may delay parasympathetic reactivation following submaximal exercise, its effect is not apparent following supramaximal exercise. This may suggest that the effect of blood O2 partial pressure on parasympathetic reactivation is limited under heightened sympathetic activation.

“…Previous studies have observed a higher rate of acute cardiovascular events(38) and a greater prevalence of hospitalization associated with vascular procedures(11) in men. Moreover, a recent study also observed that after constant load treadmill walking, men with PAD presented a slower HR recovery than women(24). Taking together, the available evidence suggests a worse cardiovascular control in men with PAD, which might be related to the greater cardiovascular responses during the constant load walking.…”

Purposes To assess the cardiovascular responses during constant load walking and to identify predictors of this response in peripheral artery disease (PAD) patients. Methods Seventy-nine patients with PAD performed a constant load treadmill test (2 mph, 0% grade). During the test, systolic blood pressure (BP), diastolic BP, and heart rate (HR) were obtained at the fourth minute to the last minute of exercise. Patients were also characterized on demographic measures, cardiovascular risk factors, baseline exercise performance and vascular measures. Results During constant load walking, there was a significant increase (p<0.01) in systolic BP (+12 ± 10 mmHg), diastolic BP (+6 ± 9 mmHg), and HR (+5 ± 5 bpm). The HR responses was negatively correlated with ischemic window (r= −0.23; p<0.05), expressed as an area under the curve of the resting ankle systolic BP and its recovery from maximal graded treadmill test, and positively correlated with the HR during the first minute of recovery from maximal graded treadmill test (r= 0.27; p<0.05). The increase in cardiovascular variables during constant load walking was greater in subjects with higher body mass index and in men (p<0.05). Conclusion Patients with PAD had an increased cardiovascular response during constant load walking, and these responses were greater in obese patients and in men. The clinical implication is that PAD patients engaged in walking training programs, particularly men and those with obesity, require frequent assessment of cardiovascular parameters to avoid exaggerated increases in BP and HR during constant load walking.
