Brief Summary

PURPOSE:

to determine the effect of aerobic exercise training and diet on sex hormones , insulin resistance and depression and if is there correlation between these factors effect in postmenopausal obese women

BACKGROUND:

The practice of regular physical activity is recommended worldwide by different public health agencies for primary or secondary prevention of many health problems, including cancers. In particular, physical activity is associated with a 25 % reduction in the average risk of cardiovascular diseases among women, and this protective effect appears to be independent of menopausal status. Many interrelated biological mechanisms may underlie this association, such as the effect of physical activity on glucose metabolism, inflammation, immune function, and sex hormones. Indeed, endogenous sex hormones, particularly estrogens, seem to be involved in the initiation, promotion, and progression of tumors. Prolonged exposure to high endogenous hormone levels is considered one of the main risk factors for female breast cancer, with a relative risk of 2.00 (95 % confidence interval (CI): 1.47-2.71) for postmenopausal women with the highest estradiol levels . Several observational studies have found an inverse association between physical activity and circulating estrogen levels . This effect may be mediated by the decrease in fat mass, the main source of estrogens in postmenopausal women. It may also be mediated by the disruption of the menstrual cycle before menopause , especially when exercise is associated with low energy intakes. However, the assessment of the exposure to physical activity remains imprecise, because it is generally only possible to measure it in naturally living subjects using questionnaires

.

HYPOTHESES:

may have no Correlation between sex hormones and insulin resistance and depression in response to exercise and diet in postmenopausal obese women

RESEARCH QUESTION:

Is there Correlation between sex hormones and insulin resistance and depression in response to exercise and diet in postmenopausal obese women?

Detailed Description

It is an interventional study in which 60 women estimated to enrol according to random allocation and assigned into two groups equal. The study group will receive aerobic exercises in addition to diet recommendations while the control group will receive diet recommendations. the aerobic exercises in form of treadmill training intensity of exercises high intensity, target heart rate (THR) will be60-70% of heart maximum (HR MAX)time of session 40 min initial 10 min warm up exercises on treadmill in low intensity and active phase20- 30 min intensity will increase until patient reach to THR then intensity decrease until session will be ended by cooling down phase for 10 min . The volunteers will perform exercises 3 times per week for 12 weeks .insulin resistance will be measured by HOMA -IR index and sex hormones (estridol ,testosterone. sex hormone binding globin ) pre and post intervention and use zung self-rating depression scale to assess depression
