Abstract(s)
O sistema nervoso simpĂĄtico e o sistema nevoso parassimpĂĄtico influenciam a
frequĂȘncia cardĂaca, expressando-se esta atravĂ©s da irregularidade dos batimentos cardĂacos
produzidos pelo coração, sendo que as oscilaçÔes dos intervalos consecutivos interbatidas são
denominadas de variabilidade da frequĂȘncia cardĂaca (VFC). Maior VFC em repouso foi
associada a maior desejo e excitação sexual, O objetivo é examinar correlaçÔes de desejo e
frequĂȘncia sexuais com a VFC em repouso. A amostra foi de 67 mulheres (M = 24.06 anos).
A frequĂȘncia cardĂaca foi medida com o sistema MP150 BIOPAC e foram calculados
domĂnios de frequĂȘncia: potĂȘncia de alta frequĂȘncia (VFC_AF) e de baixa frequĂȘncia
(VFC_BF). o desejo sexual foi medido com questĂ”es acerca da frequĂȘncia de desejo de coito
vaginal, masturbação e sexo nĂŁo coital. A frequĂȘncia sexual real destes comportamentos
também foi relatada, assim como a satisfação sexual. O desejo por coito correlacionou-se
inversamente com a VFC_AF e a frequĂȘncia coital diretamente com a VFC_AF. NĂŁo houve
correlaçÔes com a VFC_BF. A satisfação não se correlacionou nem com a VFC_AF nem
VFC_BF. Pode concluir-se a existĂȘncia de relação entre o desejo sexual e substancial
influĂȘncia simpĂĄtica. Em concordĂąncia com outros estudos, uma maior ativação
parassimpĂĄtica em repouso parece facilitar a frequĂȘncia coital.
The sympathetic nervous system and parasympathetic nervous system influence a heart rate, which reflects in variability in heart beat intervals or heart rate variability (HRV). Higher HRV at rest was previously associated with greater sexual desire and arousal. The aim of the study is to examine associations of resting HRV with sexual desire and frequency, in a sample of 67 women (M = 24.06 years). Heart rate was measured with a MP150 BIOPAC system, and HRV frequency domains were calculated: high frequency (HF) and low frequency (LF) power. Desired and actual sexual frequency of vaginal intercourse, noncoital sex, and masturbation, was reported, as well as a sexual satisfaction. The desire for coitus correlated inversely with a HF and coital frequency correlated directly with a HF. There were no correlations with LF. Satisfaction did not correlate with either a HF or LF. Sexual desire might be substantial influenced by sympathetic nervous system. In agreement with other studies, a greater parasympathetic tone seems to facilitate coital frequency.
