Avaliação da variabilidade da freqüência cardíaca em mulheres climatéricas treinadas e sedentárias

Abstract

The study suggests that aerobic training may have afforded a significant improvement in the autonomic cardiac function of the menopausal women in the active group, and may be a useful option for preserving this functional condition without the need for hormonal replacement therapy.

Functional training in postmenopause: Cardiac autonomic modulation and cardiorespiratory parameters, a randomized trial

“…This improvement in HRV was also seen in other studies. Jurca et al described an increase in the RMSSD, HFms 2 and LFms 2 indexes in postmenopausal women after 8 weeks of aerobic training, and Paschoal et al found that carrying out low‐intensity aerobic activity (at least 1 h walk daily, 3 times a week) also promoted a significant increase in SDNN, RMSSD and pNN50 in postmenopausal women when compared with sedentary women …”

“…Menopausal women have a lower HRV when compared with women who are not in menopause . Furthermore, significant reductions are observed for the RR intervals and changes in baroreceptor decline of left ventricular systole . By associating the changes induced by menopause and the deleterious effects caused by the natural aging process, such as decline in aerobic and functional capacity, and muscle capacity to generate maximum force, as well as the deterioration of the sensory system, we observed the need to seek ways to minimize the physiological loss in women arising from both processes …”

“…Studies with different types of training (aerobics, functional and instability resistance) carried out with women in menopause has seen improvement in HRV, especially with increased vagal modulation, but to our knowledge, none of these studies evaluated cardiovascular parameters and the autonomic nervous system through HRV in menopausal women undergoing functional training …”

“…3 Furthermore, significant reductions are observed for the RR intervals and changes in baroreceptor decline of left ventricular systole. 4 By associating the changes induced by menopause and the deleterious effects caused by the natural aging process, such as decline in aerobic and functional capacity, 5 and muscle capacity to generate maximum force, as well as the deterioration of the sensory system, 6 we observed the need to seek ways to minimize the physiological loss in women arising from both processes. 7 In this context, physical exercise is a potent tool for health promotion and disease prevention; 8 and the different types of training can be beneficial for menopausal women, such as aerobic training, 5 resistance training 9,10 combined training 7,11 and, recently popular in the fitness industry, 12 functional training.…”

“…16 Therefore, functional training uses unstable surfaces to recruit multiple muscle groups, and thus requires greater activation of the abdominal and back muscles, and provides various neuromuscular adaptations. 17 Studies with different types of training (aerobics, functional and instability resistance) carried out with women in menopause has seen improvement in HRV, especially with increased vagal modulation, 3,4,14,17,18 but to our knowledge, none of these studies evaluated cardiovascular parameters and the autonomic nervous system through HRV in menopausal women undergoing functional training. 19 Such information is essential to clarify the influences of this type of training on the autonomic nervous system and the cardiovascular system of menopausal women, in view of the potential cardiorespiratory benefits that functional training can bring to the population of menopausal women.…”
