“…However, Sinnreich et al (1998) and Tarkiainen et al (2005) did not observe such significant differences between the time (CV 6-11%) and frequency domain indices (CV 7-15%). A slightly lower CV for the frequency versus time domain indices was even reported by Farah et al (2014) who also presented the highest CV for the ratio indices.…”

“…Previous reliability studies have been primarily designed as a test-retest with repeating the HRV measurement(s) after several days (Al Haddad et al, 2011; Farah et al, 2014), weeks (Nunan et al, 2009) or months (Salo et al, 2001; Tarkiainen et al, 2005). These reliability study designs are definitely suitable for the repetitive inter-day HRV monitoring.…”

“…However, certain doubts about HRV analysis and following interpretation still exist (Farah et al, 2014; Pagani et al, 2012; Paso et al, 2013; Wallén et al, 2012). For instance, the reliability of the HRV measurement is not definite, even if its determination is fundamental for assessing the HRV measurement sensitivity.…”

The primary aim of this study was to assess the retest stability of the short-term heart rate variability (HRV) measurement performed within one session and without the use of any intervention. Additionally, a precise investigation of the possible impact of intrinsic biological variation on HRV reliability was also performed. First, a single test-retest HRV measurement was conducted with 20-30 min apart from one another. Second, the HRV measurement was repeated in ten non-interrupted consecutive intervals. The lowest typical error (CV = 21.1%) was found for the square root of the mean squared differences of successive RR intervals (rMSSD) and the highest for the low frequency power (PLF) (CV = 93.9%). The standardized changes in the mean were trivial to small. The correlation analysis revealed the highest level for ln rMSSD (ICC = 0.87), while ln PLF represented the worst case (ICC = 0.59). The reliability indices for ln rMSSD in 10 consecutive intervals improved (CV = 9.9%; trivial standardized changes in the mean; ICC = 0.96). In conclusion, major differences were found in the reliability level between the HRV indices. The rMSSD demonstrated the highest reliability level. No substantial influence of intrinsic biological variation on the HRV reliability was observed.

“…In recent years, especially in the field of sports science, the reliability of HRV analysis has performed under various physical activities (Dupuy et al, 2012;Boullosa et al, 2014;Candido et al, 2015;Nakamura et al, 2016). Reliability was found in good or excellent level in different studies (Sandercock et al, 2004;Farah et al, 2016). In the HRV reliability analysis, recordings are generally compared in different days.…”

The effects of effortful swallowing and solid meal ingestions on heart rate variability (HRV) have been examined previously. The effects of spontaneous saliva swallowing on short-term HRV and reliability of HRV analysis have not been studied before. The effect of saliva swallowing on HRV analyses parameters [meanRRI, SDNN (standard deviation of normal-to-normal), LF (low frequency), HF (high frequency) powers, LH/HF] and the reliability of LF and HF powers were investigated by frequency, time-frequency and intraclass correlation coefficient (ICC) analyses. Electrocardiogram and swallowing signal that obtained from an electronic stethoscope placed on the necks of subjects were recorded simultaneously from 30 healthy and young volunteers in sitting position during 15 min. Spontaneous swallowing has been shown to significantly alter some HRV parameters (SDNN, LF power and LF/HF ratio). Time-frequency analysis results showed that the contribution of saliva swallowing to LF (1-58%) and HF (2-42%) powers could change significantly depending on the number of swallowing. The ICC of the LF and HF powers for the successive 5-min signal segments were found 0·89, 0·92, respectively. These values decreased to 0·73 and 0·90 in the subjects with more swallowing rate. When the analyses were made for 2-min signal periods, these values decreased to 0·63 and 0·67. We concluded that spontaneous saliva swallowing can change HRV parameters. We have also seen that changes in swallowing rate and use of short signal segments may reduce the reliability of HRV analyses.

“…In addition to the positive effects on blood pressure, studies have analysed the effects of isometric handgrip training on the autonomic nervous system, which plays a major role in the regulation of the cardiovascular system (Badrov et al, ; Farah et al, ; Millar, Levy, McGowan, McCartney, & MacDonald, ; Stiller‐Moldovan, Kenno, & McGowan, ; Taylor, Mccartney, Kamath, & Wiley, ) and sympathetic increase and parasympathetic reduction to the heart are associated with fatal and non‐fatal cardiovascular events (Dekker et al, ; Tsuji et al, ). In these studies, cardiac autonomic modulation was assessed using heart rate variability, which is a non‐invasive method to assess cardiac autonomic modulation based on the analysis of the variations in the time between heart beats (Farah et al, ; Task Force of the European Society of Cardiology & the North American Society of Pacing & Electrophysiology, ).…”

Meta‐analyses have shown that isometric handgrip training reduces blood pressure in normotensive and hypertensive subjects. However, the effects on cardiac autonomic modulation are still controversial. Thus, the aim of this systematic review and meta‐analysis was to analyse the effects of isometric handgrip training on cardiac autonomic modulation in normotensive and hypertensive subjects. For this, Medline, Cinhal, Embase, Spordiscus and PEdro were searched for relevant studies published until December 2018. Randomized controlled trials investigating the effect of isometric handgrip training on heart rate variability parameters were considered eligible. Parameters were obtained in time (standard deviation of all the RR intervals‐SDNN, root mean square of successive differences between the normal adjacent RR intervals‐RMSSD and the percentage of adjacent intervals with more than 50 ms‐PNN50) and frequency domain (low frequency‐LF, high frequency‐HF and sympathovagal balance‐LF/HF). Mean difference (MD) and 95% confidence interval (95% CI) were calculated using an inverse variance method with a random effects model. Seven trials were included in the systematic review and meta‐analysis, totalling 86 participants. No significant effect was observed in heart rate variability parameters after isometric handgrip training (4 trials to SDNN: MD = −1.44 ms and 95% CI = −8.02, 5.14 ms; RMSSD: MD = −1.48 ms and 95% CI = −9.41, 6.45 ms; PNN50: MD = 0.85% and 95% CI = −1.10, 2.81%; 7 trials to LF: −0.17 n.u. and 95% CI = −6.32, 5.98 n.u.; HF: MD = 0.17 n.u. and 95% CI = −5.97, 6.30 n.u.; and LF/HF: MD = 0.13 and 95% CI = −0.34, 0.59). In conclusion, current literature indicates that isometric handgrip training does not improve heart rate variability.

Intra‐individuals and inter‐ and intra‐observer reliability of short‐term heart rate variability in adolescents

Abstract: Indicators of reproducibility obtained in this study suggest that HRV can be used in adolescents; however, the analysis of HRV parameters should be performed by the same person.
