Regular Walking Reduces Risk of Over Weight and visceral or subcutaneous fat accumulation in Older Adults

Visceral or subcutaneous fat accumulation is fat accumulated in the abdominal area, leading to a higher risk of insulin resistance, and its concomitant metabolic disorders (the metabolic syndrome) including atherogenic dyslipidemia(1), in comparison to those with less visceral fat accumulation.

Regular physical activity has long been found to associate to the prevention of cancer, cardiovascular disease, and other chronic diseases, but the regular walking contribution of reduced risk of visceral or subcutaneous fat accumulation in the younger and older elderly have been lacking, probably due to its association to the complication of obesity(2).


The study of a total of 173 sedentary, overweight (body mass index > or =24.0 and >33% body fat), postmenopausal women aged 50 to 75 years who were living in the Seattle, Wash, area, suggested, Walking reduced body weight and body fat among overweight and obese postmenopausal women, as it was the most frequently reported activity in the group(3).

Dr. Lynch NA and colleagues at the University of Maryland School of Medicine insisted that walking not only is associated with greater reductions in visceral adiposity in obese postmenopausal women but also improved in maximal O(2) uptake (VO(2 max)(4) of that is said to significantly improve the metabolic profile(5).

In fact, regular walking is found to reduce the risk of visceral or subcutaneous fat accumulation as it prevents the early state of weight gain.

The Okayama Southern Institute of Health in the study of Thirty one obese Japanese males (body mass index (BMI) > or = 25) ranging in age from 32 to 59, participated in a 1-year follow up study said, " intra-abdominal visceral adipose tissue is critically involved in insulin resistance and daily walking rather than improvement of exercise capacity correlated with the reduction of visceral adipose tissue in obese Japanese males."(6). As walking significantly lowers serum leptin concentrations(8), and thus it may improve the leptin resistance observed in overweight adults(7).
