Associação Entre a Atividade Física De Lazer E De Deslocamento Com a Variabilidade Da Frequência Cardíaca Em Adolescentes Do Sexo Masculino

Abstract

Objective: To investigate the association between heart rate variability (HRV) parameters with leisure time and commuting physical activities in adolescent boys. Methods: The sample included 1152 male adolescents aged 14 to 19 years. The variation of consecutive heart beats (RR intervals) was assessed and HRV parameters in time (SDNN, RMSSD, pNN50) and frequency domains (LF/HF) were calculated. Leisure time and commuting physical activities were obtained using a questionnaire. A binary logistic regression was performed between HRV parameters and physical activity. Results: Leisure time physical activity was associated with SDNN, RMSSD, pNN50, while LF/HF was not associated. These associations were stronger when adolescents were also physically active for more than six months. Commuting physical activity was not associated with any HRV parameter. Boys who practiced commuting physical activity and were also physically active for more than six months presented a lower chance of having low SDNN and RMSSD. Conclusions: Leisure time physical activity was associated with better HRV and these associations were enhanced when adolescents were physically active for more than six months. Commuting physical activity was not associated with HRV parameters; however, it became associated with better HRV when adolescents were physically active in commuting for more than six months.

Influência Do Tempo De Internação Hospitalar Sobre a Variabilidade Da Frequência Cardíaca Pediátrica Por Meio De Método Linear

“…Associado a isso, estudos anteriores constatam que a VFC pode ser usada para a obtenção de pontos corte que determinam o aparecimento de complicações em internações, como infecções, ou na ocorrência de reduções da modulação autonômica, como a que se encontra em casos de diabetes mellitus (CORRÊA, 2006;SILVA et al, 2017). Além disso, pesquisas mostram correlação entre a gravidade de doenças como fibrose cística e anemia falciforme em alterações da VFC normais, assim como possuem relação de melhor adaptação em indivíduos que realizam atividade física PALMEIRA et al,2017;LUGAO et al, 2022).…”

Association between Sleep Quality and Cardiac Autonomic Modulation in Adolescents: A Cross Sectional Study

“…6 7 8 In adolescents, a decrease in parasympathetic and an increase in sympathetic modulation is associated with obesity, 9 10 high blood pressure, 11 and low physical activity levels. 12…”

“…[6][7][8] In adolescents, a decrease in parasympathetic and an increase in sympathetic modulation is associated with obesity, 9,10 high blood pressure, 11 and low physical activity levels. 12 Based on the aforementioned findings, a correlation between cardiovascular outcomes and sleep quality/ duration 3,13,14 suggests that adolescents with shorter or poor sleep quality experience poor cardiac autonomic modulation. 4 Furthermore, sleep quality and variability in sleep duration increased sympathetic modulation and decreased parasympathetic modulation.…”
