“…To the best of our knowledge, no previous study has evaluated the reproducibility of time-varying HRV analysis after maximal exercise using passive and active recovery. Previous evidence has confirmed the clinical usefulness of post-exercise cardiac autonomic recovery assessments using both passive [4,5,29] and active [17,30] recovery. Since these conditions yield different hemodynamic responses [31], it could be hypothesized that the reproducibility of post-exercise HRV would be different between them.…”

“…Such discrepancies may be related to the method of signal selection, since most of the previous studies considered the average of total recovery period [7,10,11]. The time-varying of the RMSSD in segments of 30 sec is widely employed in literature [5,[15][16][17]. However, the reproducibility of RMSSD in segments of 30 sec was assessed in only one study [10].…”

AbstractTo analyze whether heart rate variability is reproducible after maximal exercise, 11 men (22.1±3.2 years) performed four incremental exercise tests followed by passive or active recovery. There was high reliability (intraclass coefficient correlation: 0.72–0.96) and fair-to-excellent agreement (coefficient of variation: 7.81–22.09%) in passive recovery, as well as moderate-to-high reliability (intraclass coefficient correlation: 0.50–0.87) and good agreement (coefficient of variation: 11.08–20.89%) in active recovery for LnRMSSD index. There was moderate-to-high reliability (intraclass coefficient correlation: 0.51–0.81) and good agreement (coefficient of variation: 10.41–18.87%) in most of the analyzed time points, in both recovery types for LnSDNN. In both types of recovery, the time domain heart rate variability 5–10 min indices (passive: intraclass coefficient correlation : 0.87–0.88; coefficient of variation: 7.67–13.44%; active: intraclass coefficient correlation 0.59–0.80; coefficient of variation: 14.62–16.26%) presented higher intraclass coefficient correlation and lower coefficient of variation than the spectral heart rate variability indices (passive: intraclass coefficient correlation: 0.71–0.87; coefficient of variation: 12.33–34.21%; active: intraclass coefficient correlation: 0.46–0.77; coefficient of variation: 24.41–105.12%). The LnRMSSD and LnSDNN indices analyzed in 30 s segments and the heart rate variability 5–10 min indices after maximal exercise in untrained healthy men showed satisfactory reproducibility, regardless of the type of recovery, with the time-domain indices showing higher reproducibility than the frequency-domain indices.

“…Previous studies in obese young adults have evaluated the HRV and BP over a short period of time both at rest [3,17]and immediately after a maximal test [14,18]. Our results emphasize the importance of 24 h continuous monitoring of autonomic and cardiovascular variables, especially in obese individuals.…”

“…On the other hand, in other studies, obesity was not seen to cause HRV and BP impairment in young adults [17,18]. However, these analyses were performed over a short period of time, both at rest [17], and immediately after maximal test [18]. To our knowledge, there is no information about 24 h cardiac autonomic and cardiovascular responses to obesity and maximal exercise for men in early adulthood.…”

“…Additionally, BP reduction has been studied in overweight/obese subjects and those with other chronic-degenerative diseases [10,12] after induced stress. On the other hand, in other studies, obesity was not seen to cause HRV and BP impairment in young adults [17,18]. However, these analyses were performed over a short period of time, both at rest [17], and immediately after maximal test [18].…”

This study aimed to assess whether obesity and/or maximal exercise can change 24 h cardiac autonomic modulation and blood pressure in young men. Thirty-nine men (n: 20; 21.9±1.8 kg·m−2, and n: 19; 32.9±2.4 kg·m−2) were randomly assigned to perform a control (non-exercise) and an experimental day exercise (after maximal incremental test). Cardiac autonomic modulation was evaluated through frequency domain heart rate variability (HRV). Obesity did not impair the ambulatory HRV (p>0.05), however higher diastolic blood pressure during asleep time (p=0.02; group main effect) was observed. The 24 h and awake heart rate was higher on the experimental day (p<0.05; day main effect), regardless of obesity. Hypotension on the experimental day, compared to control day, was observed (p<0.05). Obesity indicators were significantly correlated with heart rate during asleep time (Rho=0.34 to 0.36) and with ambulatory blood pressure(r/Rho=0.32 to 0.53). Furthermore, the HRV threshold workload was significantly correlated with ambulatory heart rate (r/Rho=− 0.38 to−0.52). Finally, ambulatory HRV in obese young men was preserved; however, diastolic blood pressure was increased during asleep time. Maximal exercise caused heart rate increase and 24h hypotension, with decreased cardiac autonomic modulation in the first hour, regardless of obesity.
