“…For the HRV analyses, the stretches with the highest signal stability were selected, including at least 256 consecutive beats (Task Force, 1996). In addition, volunteers were instructed to abstain from alcohol and stimulants for at least 12 hours before the test, to avoid strenuous exercise, and to have a period of regular and good quality sleep on the night before data collection (Minatel et al, 2012;Zuttin et al, 2008). Volunteers who did not follow these guidelines were excluded from the analysis, leaving 54 individuals.…”

This study evaluated the effects of physical exercise on cardiovascular and psychobiological health (levels of anxiety, depression, fatigue) in university students. A cross-sectional study was conducted, including 72 students in the health care field in 2018. First, an anamnesis was conducted, with information on the eligibility criteria and the physical exercise they practice, to obtain the groups "practices physical exercise" and "no physical exercise." Among eligible individuals, anthropometric measurements were taken, heart rate variability was recorded, questionnaires on depression, anxiety, fatigue, and physical activity were applied, along with a cardiorespiratory test. Of the student participants, 45.0% were female, 20.0% were male, and 42 reported exercising, 30 did not. High levels of depression, anxiety, fatigue, and body fat percentage above adequate levels were observed in the study group. Students who practiced physical exercise had lower depression scores, lower body fat percentage, and better autonomic modulation when comparing study groups. There was no difference in cardiorespiratory fitness between practitioners and non-practitioners of physical exercise. A more active lifestyle, including the practice of regular physical activity, is a practical component in improving cardiometabolic and psychobiological profiles in university students and, therefore, should be encouraged during university life.

“…Os mais frequentes são os transtornos depressivos e de ansiedade (Cerchiari, Caetano & Faccenda, 2005;January et al, 2018;Noureen & Malik, 2019). Estes dados são alarmantes, visto que figura-se no público jovem a maior propensão a tentativas de suicídio, além de que os transtornos depressivos para tal faixa etária constituem fator de risco para doenças cardiovasculares (Associação Brasileira (Zuttin et al, 2008;Minatel et al, 2012).…”

The non-linear analysis of the heart rate variability (HRV) is a potential correlation tool between physiological and emotional states. The aim of this study was correlate changes in non-linear parameters of the HRV with anxiety and depression indices in higher education entrants from Federal University of Goiás (UFG). To record HRV, the Polar Frequency Metermodel Polar® RS800cx (Electro Oi, Finland) was used. To analyze the levels of depression, the Beck Depression Inventory-I (BDI) was used, and for analysis of anxiety, the Inventories of State and Trace (IDATE T and E). Altogether, 50 (19.4±2.48 years) volunteers participated in the study. The scores of the depression and anxiety inventories indicated that the public had low and moderate indices of both conditions, respectively. Statistically significant correlations were found between the SD2 parameter (from the Poincaré plot in the HRV analysis), entropy data (ApEn and SampEn) and fractal property (DFA: α1) and trait and state anxiety levels. Although ApEn e SampEn still do not have well-defined physiological correspondences, DFA: α1 has been associated with parasympathetic modulation of heart rate. Therefore, it is concluded that chronic negative emotional states, such as anxiety and humor disorders, can be accompanied by parasympathetic increase in HRV, so the organism would be able to not wear out against long-term stressors. New studies are necessary to understand the physiological and evolutional bases of depression and anxiety.

“…Nas mudanças posturais ocorrem alterações das variáveis cardiovasculares devido aos desvios hidrostáticos e respostas reflexas causadas pelo movimento sanguíneo das extremidades superiores para as inferiores, redução do volume sistólico, aumento da frequência cardíaca para manter a pressão arterial e o débito cardíaco, ativação dos receptores arteriais e cardiopulmonares, com diminuição da variabilidade da frequência cardíaca pela menor ativação do vago sobre o nodo sinusal 24,25 .…”

ResumoO estudo da Variabilidade da Frequência Cardíaca (VFC) tem permitido, de forma não invasiva, avaliar o Sistema Nervoso autônomo e o risco cardíaco, sendo um importante indicador prognóstico de doenças cardíacas e sistêmicas. O objetivo foi avaliar e comparar a VFC no domínio da frequência e do tempo de idosos com hipertensão arterial e de idosos saudáveis frente à mudança postural de repouso para sentado. Foram estudados 18 indivíduos hipertensos e 18 indivíduos saudáveis na faixa etária de 60 a 85 anos. A frequência cardíaca e os intervalos R-R foram coletados pelo instrumento Polar S810i durante 1200 s nas posturas supina e sentada. A VFC foi analisada no domínio do tempo - DT pelas variáveis: Índice raiz quadrada da média dos quadrados das diferenças entre intervalos R-R (iR-R) sucessivos (RMSSD), desvio padrão da média dos iR-R normais em ms - SDNN e PNN50%, que traduz a diferença de duração superior a 50 milissegundos, e no domínio da frequência, pelas bandas de alta (AF) e baixa frequência (BF), e da razão BF/AF. Ocorreu alteração na VFC dos idosos tanto no grupo controle e hipertenso, no entanto não houve mudanças significativas na VFC entre os grupos estudados. Ao analisar a VFC no domínio do tempo, o estudo mostrou que a amostragem estudada apresenta alto risco cardíaco ao analisar o parâmetro SDNN. Conclui-se que a mudança postural alterou a VFC desses idosos, tanto no grupo controle e hipertenso, no entanto não houve mudanças significativas na VFC entre as fases dos grupos estudados e obteve-se como resultado alto risco cardíaco ao avaliar o parâmetro SDNN em ambos os grupos.Palavras-chave: Hipertensão.

Frequência Cardíaca.AbstractThe study of heart rate variability (HRV) allows noninvasive way to evaluate the autonomic nervous system and cardiac risk, and an important prognostic indicator of heart and systemic diseases disease. The objective was to evaluate and compare the HRV in the frequency and duration of elderly patients with hypertension and healthy elderly versus postural change in the condition of rest. The study comprised 18 hypertensive individuals and 18 healthy subjects aged 60 to 85 years, both sexes. Heart rate and RR intervals were collected by the instrument Polar S810i during 1200 s in supine and sitting postures. HRV was analyzed in time domain indices SDNN, RMSSD and PNN50% and the frequency domain, by bands of high (AF) and low frequency (LF), and the ratio LF / HF. Intergroup intra-analyes were used as well as the tests of normality D’Augustine as a criterion for parametric groups. There was change in heart rate variability of both the elderly and hypertensive patients in the control group, however there were no significant changes in studied HRV intergroups . In the area of the time it was found that the sampling shows high-risk cardiac parsing the parameter SDNN. The results showed that the change posture changed the variability of heart rate in the control group and hypertension, however there were no significant changes in HRV among the phases of the groups and a high risk was obtained as a result of the parameter SDNN for both heart the groups.Keywords: Hypertension.
