Filter by:This trial investigates whether supervised training in combination with hormonal substitution therapy has an impact on body composition, cardiovascular risk and insulin sensitivity in postmenopausal women.
Background: In postmenopausal women, an alteration in body composition occurs as a consequence of the secretion of low levels of serum estrogens by the ovaries. Observing an increase in abdominal and mammary fat mass and a decrease in skeletal muscle mass, which is also accompanied by loss of muscle strength and physical function, which leads early to a sarcopenia. On the other hand, the increase in estrogen production by adipose tissue has been associated with an increased risk of breast cancer during menopause because the mammary parenchyma is particularly sensitive to this type of estrogen. For this reason, Hormone Therapy (Aromatase Inhibitors and Tamoxifen) is prescribed in women with estrogen receptor-positive breast cancer. Antineoplastic treatments (Chemotherapy and Hormonal Therapy) have contributed to non-metastatic breast cancer currently presenting a high survival rate, not without adverse effects associated with the course of the disease, age and antineoplastic treatment, affecting various systems, but particularly skeletal muscle mass. Therefore, resistance exercise training has been proposed as an effective intervention strategy to increase muscle mass and strength in different populations. However, the level of muscle response to this type of training in postmenopausal women survivors of breast cancer with and without hormone treatment (Aromatase Inhibitors and Tamoxifen) is unknown.
This study aims to explore the sensitivity of an innovative marker, HE4, in the diagnosis approach of endometrial cancer in case of postmenopausal bleedings.
The aim of the study will be comparing the effectiveness of two diets: moderate in fat with a high proportion of monounsaturated fatty acids (MUFAs) - the Mediterranean diet (MED) and 2) the low in fat and high in dietary fiber contents the dietary approaches to stop hypertension diet (DASH) on weight maintenance and cardiovascular risks following a recent body weight reduction in centrally obese postmenopausal women. The tested diets will be given ad libitum manner. Moreover, adherence to both prescribed weight-loss maintenance diets will be also evaluated by the plasma concentration of alkylresorcinols (AR) as a possible whole grain wheat/rye dietary biomarker and by the analysis of fatty acids profile in erythrocyte membranes as a dietary biomarker of a fatty acids consumption. The participants of this study will be 150 non-smoking, postmenopausal women with central obesity, who wished to lose weight and have at least one other criterion of metabolic syndrome. The intervention will include 3 phases: Phase I (weeks 1-8), weight loss dietary intervention with 700 kcal/d energy deficit, Phase II (week 9-32), weight loss maintenance intervention for those participants losing ≥10% initial body weight the MED or the DASH diet will be offered in a random manner. The control group will receive oral dietary recommendations based on the Harvard model "Healthy Eating Plate". After this 32 weeks period will be finished, the participants will be discharged to the community with no contact by study personnel, until the 52-weeks follow-up period (Phase III).
This study intends to evaluate the impact of resistance training variable manipulation (intensity and volume) on body composition, fatigability and functional capacity in postmenopausal breast cancer survivors.
