Physical inactivity and the onset of menopause increase the risk of cardiovascular disease amongst postmenopausal women. We aim to investigate the effect of resistance training (RT) on plasma levels of selected cytokines, adipokines, myokines, and sex hormones in postmenopausal women with vasomotor symptoms. This was a sub-study of a randomised controlled trial investigating the effects of RT on vasomotor symptoms in postmenopausal women. Women were randomised to join a 15-week RT program (n = 26) or remain sedentary as control (n = 29). Venous blood samples were taken at week-0 and week-15 for all participants. Enzyme-linked immunosorbent assays and multiple bead assays were used to measure cytokines, adipokines, myokines, and sex hormones in plasma. Plasma measurements of 16 of 33 analytes were within detectable limits. After adjusting for good compliance in the RT group (58% of RT participants), after 15 weeks, significantly lower plasma levels of adiponectin (p < 0.001), lipocalin-2 (p < 0.01) and resistin (p = 0.04) were found. Comparing control and RT women, using change-over-time values, significant increases in median testosterone and sex hormone binding globulin levels were seen in RT women. RT intervention lowers the levels of adipokines, particularly adiponectin, in postmenopausal women with vasomotor symptoms. These results were secondary outcomes of a clinical trial, and further investigations in a larger cohort are essential with the additional control of diet control and body composition analyses. Nevertheless, our study shows RT may be a beneficial intervention in reducing inflammation amongst postmenopausal women.

The objective of this study was to determine if 15 weeks of resistance training (RT) can alter the levels of blood lipids, body iron status, and oxidative stress in postmenopausal women with vasomotor symptoms. Postmenopausal women enrolled in a randomised controlled trial were allocated to either a sedentary control group (n = 29) or a RT group (n = 26). Blood samples were taken at week-0 and week-15 for all participants. Blood lipids and iron status were measured via routine clinical analyses. Immunoassays were used to measure oxidative stress markers. The RT group, with good compliance, was associated with significant reductions in ferritin, total cholesterol, low-density lipoprotein, and non-high-density lipoprotein cholesterol. Moreover, ferritin was positively correlated with atherogenic lipids while negatively correlated with high-density lipoprotein in RT women. This occurred without alterations in serum iron, transferrin, transferrin-saturation, C-reactive protein and oxidative stress markers. No differences were found in control women. This study suggests that RT in postmenopausal women both reduces levels of ferritin and counteracts atherogenic lipid profiles independent of an apparent oxidative mechanism. RT may be a beneficial intervention in postmenopausal women via an interaction between ferritin and lipids; however, further investigation in a larger cohort is essential.

Objectives: To investigate the effect of 15 weeks of resistance training on the frequency of moderate to severe hot flushes in postmenopausal women., Study Design: Postmenopausal women with at least 4 moderate or severe hot flushes or night sweats per day day were randomized to a 15-week resistance training intervention or unchanged physical activity. Participants did not exercise regularly at baseline and had not used any therapy for hot flushes two months prior to study entry. The resistance training was performed three times per week and the program contained 8 exercises performed with 8-12 repetitions in 2 sets. Loads were set individually from eight-repetition maximum-strength tests and increased progressively., Main Outcome Measures: The primary outcome was change in mean moderate or severe hot flushes per day from baseline to week 15, assessed with symptom diaries. Secondary outcomes included change in hot flush score and time spent on physical activity., Results: Between November 19, 2013, and October 26, 2016, 65 women were enrolled; 58 completed the trial and were included in the analyses. The mean age was 55 and the mean number of moderate or severe hot flushes per day at baseline was 7.1; there were no baseline differences between groups. The frequency of hot flushes decreased more in the intervention group than in the control group (mean difference -2.7, 95% CI -4.2 to -1.3). The mean percentage change was -43.6% (-56.0 to -31.3) in the intervention group and -2.0% (-16.4-12.4) in the control group., Conclusion: A 15-week resistance-training program decreased the frequency of moderate and severe hot flushes among postmenopausal women and could be an effective and safe treatment option to alleviate vasomotor symptoms., (Copyright © 2019 The Authors.

Objectives: Hot flushes and night sweats affect 75% of all women after menopause and is a common reason for decreased quality of life in mid-aged women. Hormone therapy is effective in ameliorating symptoms but cannot be used by all women due to contraindications and side effects. Engagement in regular exercise is associated with fewer hot flushes in observational studies, but aerobic exercise has not proven effective in randomized controlled trials. It remains to be determined whether resistance training is effective in reducing hot flushes and improves quality of life in symptomatic postmenopausal women. The aim of this study is to investigate the effect of standardized resistance training on hot flushes and other health parameters in postmenopausal women., Study Design: This is an open, parallel-group, randomized controlled intervention study conducted in Linköping, Sweden. Sixty symptomatic and sedentary postmenopausal women with a mean of at least four moderate to severe hot flushes per day or 28 per week will be randomized to an exercise intervention or unchanged physical activity (control group). The intervention consists of 15 weeks of standardized resistance training performed three times a week under supervision of a physiotherapist., Main Outcome Measures: The primary outcome is hot flush frequency assessed by self-reported hot flush diaries, and the difference in change from baseline to week 15 will be compared between the intervention group and the control group., Conclusion: The intention is that this trial will contribute to the evidence base regarding effective treatment for hot flushes., (Copyright © 2015 Elsevier Ireland Ltd.

Internet-delivered therapies have a short history and promising results have been shown for several health problems, particularly for psychiatric conditions. This study was a first attempt to evaluate whether Internet-delivered applied relaxation for hot flushes in postmenopausal women may be useful. Due to a high drop-out rate the study was prematurely terminated after inclusion of approximately two thirds of calculated women. The Internet-delivered applied relaxation must probably be modified for such populations and settings before it can be used further. This article will discuss the benefits and pitfalls to learn in order to meet the challenges of future studies.

Objective: This work aimed to study the efficacy of group therapy with applied relaxation on vasomotor symptoms and health-related quality of life in postmenopausal women., Methods: In this open, randomized controlled trial, 60 healthy postmenopausal women with at least seven moderate to severe hot flashes per 24 hours were randomized to either group therapy with applied relaxation (n = 33) or untreated control group (n = 27) for 12 weeks. A follow-up visit was scheduled 3 months after the end of therapy or participation in the control group. Salivary cortisol was measured three times during a 6-month period. Hot flashes were recorded in self-registered diaries, and health-related quality of life was assessed with the Women's Health Questionnaire., Results: The number of hot flashes decreased by 5.0 per 24 hours in the applied relaxation group compared with 1.9 in the control group on the 12th week (P < 0.001) and still remained at the same level at the 3-month follow-up (P < 0.001). Health-related quality of life for vasomotor symptoms, sleep, and memory improved significantly on the 12th week measurement in the applied relaxation group compared with the control group. Salivary cortisol concentration was lowered markedly in the applied relaxation group on a single measurement but was otherwise mainly stable in both groups., Conclusions: Applied relaxation can be used to treat vasomotor symptoms in healthy postmenopausal women.
