Background: Although post-menopausal obesity is an important public national health problem in Saudi Arabia, to date no study has evaluated the effects of weight reduction on biochemical & clinical parameters and quality of Life for obese Saudi post-menopausal women. Objective: The aim of this study was examine the effects of aerobic versus resisted exercise training effects upon systemic inflammation biomarkers and quality of life for obese post-menopausal Saudi women. Material and Methods: One hundred Saudi post-menopausal obese women participated in this study, their age ranged from 50-58 years and their body mass index (BMI) ranged from 30-35 kg/m2. All participants were divided into two equal groups: The first group received aerobic exercise training on treadmill where, the second group received resisted exercise training. Health-related quality of life (SF-36 HRQL), tumor necrosis factor– alpha(TNF-α), Interleukin-2(IL-2), Interleukin-4 (IL-4), Interleukin-6 (IL-6) and C-reactive protein (CRP) were measured before and after 3 months at the end of the study. Results: The mean values of SF-36 HRQL subscale scores were significantly increased, while the mean value of TNF-α, Il-2, IL-4, IL-6,CRP and BMI were significantly decreased in both groups after treatments. There were significant differences between mean levels of the investigated parameters in group (A) and group (B) after treatment with more changes in patients received aerobic exercise training. Conclusion: The current study provides evidence that aerobic exercise is more appropriate than resisted exercise training in modulating inflammatory cytokines and quality of life among obese post-menopausal women.Keywords: Aerobic exercise; resisted exercises; inflammatory cytokine; quality of life; obesity; menopause.

The ability to maintain energy balance is a vital factor in maintaining body composition. A negative energy balance requires that body tissue be consumed to sustain biochemical and physiological activity. Such a caloric imbalance coupled with reduced physical activity results in (among other things): a negative balance which can not be reversed by increased protein intake; negative balances for electrolytes; and a suspension of erythrocyte production. Body weight losses were experienced by all astronauts during Gemini and Apollo missions. Data on the magnitude of the changes, together with data on energy consumption, were used to calculate energy imbalances. These data, when compared with results obtained from precise energy balance measurements made on 64 men living in low pressure chambers, show close correlation. When energy requirements are expressed in kilocalories per kilogram of body weight, the difference in energy requirements among the astronauts and chamber subjects was small and not statistically significant. These data indicated that reliable prediction of energy needs for astronauts, during long-term space missions, can be made by studying either the astronauts or healthy subjects in a ground-based environment similar to that of the spacecraft. These data also indicate that changes in body weight and certain other body measurements detected during Gemini and Apollo missions were probably caused, at least in part, by a calorie deficit.
