Objective:
To verify the efficacy of phytoestrogen supplementation combined with aerobic and resistance training on the improvement of climacteric symptoms and health-related quality of life (HRQoL) in postmenopausal women.
Methods:
From a pool of women who had participated in a 1-year intervention study and were randomly assigned to either exercise + phytoestrogen (EX + PHY) or exercise + placebo (EX + PL), a total of 31 healthy but overweight women (mean age 59.2 ± 4.8 years, body mass index 29.1 ± 3.5 kg/m2) finished the study (EX + PHY, n = 15; EX + PL, n = 16). All the following variables were measured before, after 6 months and after 12 months of intervention: body composition (fat and lean body mass, DXA), HRQoL (SF-36 questionnaire: physical and mental component summaries and subscales; and the 10-item Perceived Stress Scale questionnaire), climacteric symptoms (Kupperman Index questionnaire).
Results:
After 1 year of intervention, physical functioning (p = 0.003), role-emotional (p = 0.031), vitality (p = 0.007), and global health (p < 0.001) were significantly and similarly increased in both groups. Regarding climacteric symptoms, an improvement in the Kupperman index total score (p = 0.015) was observed.
Conclusion:
Our results demonstrate that adding phytoestrogens to exercise training does not provide the additive effect for HRQoL in postmenopausal and overweight women. Moreover, exercise and phytoestrogen may interfere in the improvement of climacteric symptoms in the long term.

01:22Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
