BACKGROUND: Menopause related symptoms modify quality of life and may also have an impact on work ability. OBJECTIVE: The aim of this study was to investigate the effects of physical exercise on work ability and daily strain among women with menopausal symptoms. METHODS: Occupationally active symptomatic menopausal women (n=123) were randomized into 24-week aerobic exercise intervention and control groups. Mobile phone questionnaires were used to collect daily data on perceived physical and mental strain in a randomised and controlled setting. Work ability was measured with the Work Ability Index (WAI) and with questions about work strain. PARTICIPANTS: In all 123 women aged 44–62 (mean age 53.8 ± 3.4) years who worked full- or part-time participated in the study. Women were randomized into a control (n=60) and intervention group (n=63). The subjects were mostly working in mentally demanding jobs (e.g. office worker), but also in physical (e.g. cleaner) and mixed (physical and mental) jobs (e.g. nurse). RESULTS: The increase in mental resources and decrease in physical strain from baseline to end were statistically significantly greater among the intervention group than among the control group. Between-group differences in the change in WAI were, however, statistically non-significant. CONCLUSION: A 6-month physical exercise intervention among symptomatic menopausal women seems not to be enough to increase perceived work ability but the physical exercise may increase perceived mental resources and decrease perceived daily physical strain.}
