“…Heart rate variability (HRV) consists of the fluctuations in R-R interval (iRR) between successive heartbeats defined by the distance between two R-waves on the electrocardiogram 1,2 . HRV has been used either in sports or in clinical settings as a proxy of the cardiac autonomic function 3,4 . In this sense, different HRV methods and indices have been proposed to evaluate the parasympathetic activation or its withdraw associated with various physiological conditions such as exercise 5,6 .…”

Heart rate variability threshold (HRVT) is a valid method to determine parasympathetic depression during an incremental exercise test (IET). However, HRVT is usually assessed using the last 60s of each 180s stage of an IET, resulting in longer and demotivating tests. This study aimed to evaluate the agreement of HRVT analysis adopting the first and second minute of R-R interval (iRR) segment comparatively to a standard third-minute segment obtained at each 3-min stage on IET. Methods: Seventeen young male subjects (22.2 ± 3.1 years; 23.4 ± 2.3 kg/m 2) underwent IET on a cycle ergometer. HRVT was considered the load corresponding to the point of stabilization of the SD1 index (HRVTV), or the first load with SD1 value < 3ms (HRVT<3), both assessed by the 1 st (HRVT1V, HRVT1<3), 2 nd (HRVT2V, HRVT2<3) and standard 3 rd (HRVT3V, HRVT3<3) 60s iRR segment analyzed at each stage of IET. Agreement and reliability were assessed by the Bland-Altman analysis and the intraclass correlation coefficient (ICC), respectively. Results: High reliability and non-significant bias were observed considering HRVT1V vs HRVT3V (ICC = 0.92; p = 0.18) or HRVT2V vs HRVT3V (ICC = 0.94; p = 0.99). However, lower reliability was observed for HRVT1<3 vs HRVT3<3 (ICC = 0.79; p = 0.75) and for HRVT2<3 vs HRVT3<3 (ICC = 0.91; p = 0.33). Conclusion: HRVT can be similarly assessed by the 1 st , 2 nd or 3 rd 60 seconds iRR segment, mainly when assessed by a visual method.

Pessoas com Síndrome de Down (SD) apresentam um risco até dezesseis vezes maior de mortalidade em decorrência de doenças cardiovasculares. Um dos principais fatores são baixos níveis de aptidão cardiorrespiratória sendo, disfunção autonômica, capacidade ventilatória reduzida e disfunção metabólica. A prática do exercício físico regular e de forma orientada, produz uma série de respostas fisiológicas e importantes modificações autonômicas e hemodinâmicas, que influenciam diretamente no sistema cardiovascular. Contudo, é preciso cautela para incrementar tanto quanto possível a segurança da prática do exercício físico, onde a modulação vagal da frequência cardíaca é influenciada por vários fatores, também sendo um marcador de prognóstico de morte súbita e mortalidade. O objetivo deste artigo consiste em analisar o comportamento da frequência cardíaca em indivíduos com SD. Foram realizadas buscas nos bancos de dados ScienceDirect, PubMed, Scielo, BVS e Cochrane, com o intuito de identificar artigos sobre o tema deste estudo. Como resultado, foram selecionados 8 artigos, de acordo com os critérios de inclusão e exclusão. Sendo assim, podemos considerar que a prática de exercício promove efeitos positivos na eficiência cardíaca. No entanto, a trissomia 21 é um distúrbio genético com diversas consequências fisiológicas que podem interferir nos resultados. Como vimos, dependendo da modalidade, a modulação vagal da frequência cardíaca pode variar comparadas às pessoas sem deficiência.

“…Of the remaining 53 articles, 33 did not meet the inclusion criteria, leaving 20 to undergo a full-text analysis. Finally, 5 more articles were discarded for specified reasons (see Figure 1), leaving a total of 15 studies to be included in the systemic review [50][51][52][53][54][55][56][57][58][59][60][61][62][63][64]. One additional study was identified by checking the references within these 15 studies.…”

Individuals with Down syndrome (DS) present similar heart rate variability (HRV) parameters at rest but different responses to selected movement maneuvers in comparison to individuals without DS, which indicates reduced vagal regulation. The present study undertakes a scoping review of research on HRV in individuals with DS, with special attention paid to the compliance of the studies with standards and methodological paper guidelines for HRV assessment and interpretation. A review was performed using PubMed, Web of Science and CINAHL databases to search for English language publications from 1996 to 2020 with the MESH terms “heart rate variability” and “down syndrome”, with the additional inclusion criteria of including only human participants and empirical investigations. From 74 studies, 15 were included in the review. None of the reviewed studies met the recommendations laid out by the standards and guidelines for providing the acquisition of RR intervals and necessary details on HRV analysis. Since authors publishing papers on this research topic do not adhere to the prescribed standards and guidelines when constructing the methodology, results of the research papers on the topic are not directly comparable. Authors need to design the study methodology more robustly by following the aforementioned standards, guidelines and recommendations.
