(Mayo Clinic Health Letter,January Edition 2008 ) Moderate Obesity Recommendations PHYSICA ACTIVITES NUTRITION Brisk Walking and Jogging Drink Plenty Water, avoid soda Swimming Eat Slow and consciously Prefer Stairs as much as possible Replace Milk with Soy Milk Involve more in Household activities 1 Vegetarian Meal / Day (Fruits & Vegetables) Avoid Sleeping in Afternoon (Access Sleeping decreases Basal Metabolic Rate Don't Skip Breakfast 20-25gms of fiber diet e.g. Soya beans,oats,carrots and Broccoli Eat 2 Teaspoons of Honey 4. SPORTS AS PER SOMATOTYPE AND BODY COMPOSITION Somatotype is the key element in analyzing the sports potential. The Structure or built of person is known as Somatotype. My Somatotyoe is as below: SOMATOTYPE SPORT RECOMMENDED AVOID MESOMORPHIC Decathlon,Gymnastics,Rowing and Swimming Marathoning, Mountain biking & Golf The above mentioned recommendations are on the basis of skills and body structure required for a particular sport. "Mesomorphs rank high on strength, endurance and agility and therefore is best suited for the above mentioned sports." (Sports Potential, Measurement Description, Overview) 5. AFFECT OF HYDRATION LEVEL ON DXA, BIA AND SKINFOLD A. Hydration Level and DXA Test: Ideally with a decrease in hydration there should be an increase in element content (like Na, K, Cl) leading to a higher molecular weight of the body and thus change in attenuation coefficient. In the study done by Going and colleagues, it was found that the 98% of weight change due to dehydration was measured by DXA. (Human Body Composition, By Steven Heymsfield, Pg 75) A normal variation in hydration level (1-3 %of body weight)...In the study done by Going and colleagues, it was found that the 98% of weight change due to dehydration was measured by DXA. (Human Body Composition, By Steven Heymsfield, Pg 75) A normal variation in hydration level (1-3 %of body weight) has very little affect on measurement by DXA method. Variation in Hydration level blazes DXA estimates of percentage fat only 1-2.5 %.This interprets that Hydration Level doesn't have much affect on DXA measurement. B. Hydration Level and BIA Test: "In an experiment done, with decrease in Hydration level, Bioelectric Impedance (BI) decreased from 14.4 5.3% to 12.3 5.3%, After Rehydration, BI % increased to 15.5 5.8%. Similar findings occurred when subjects were super hydrated (Normal-BI = 13.2 5.3%; Super hydration -BI = 15.4 5.6%)." (SAUNDERSM. J. (1) ; BLEVINSJ. E. (1) ; BROEDERC. E. (1) ) B. Hydration Level and SKINFOLD: With the increase level of Water in the body, the Value in Skin fold test increases. High extra cellular water in subcutaneous tissues causes thickness of and hence the value calculated is incorrect. "Martin, Drink water and Clays(1992) reported that variation in skin fold compressibility may be an important limitation of this method.
