Abstract
Objective: To evaluate the effects of proper dietary and exercise practice on bone mineral quality, skelet muscle and fatty mass in a person aged > 60y. Subject & Methods: A 60 ys- old male subject, risk of osteoporosis received the daily diet 2000Kcal, Ca 1300mg, protein 1.7mg/kg.bw, vitamin D 665IU. Endurance exercise 3 times/week x 60 minutes/ session with moderate & high intensity levels; 45 minutes daily morning with moderate and light intensity, and 8 hours working at office. Heel- bone mineral density (BMD) measured by Quantitative Ultra-Sonic (QUS) instrument, skelets muscle and fat mass by Inbody 370S intrument every 6 months. The study period lasted 60 months (T60). Results: The T-score of heel bone increase from -2.4 (high risk osteoporosis) at the beginning (T0) to level of pick bone mass at T36, then maintained until T60 of intervention. The BUA (Broadband Ultrasound Attenuation), reflects the quality of the bone s’ trabecular, were also improved from 39.5dB/MHz to 108.1dB/MHz (+173.7%) from T0 to T60 respectively. The body weight, skelet-muscle & fat mass were maintained quite stable during 60 months of the study. Conclusion: A proper diet and exercise restored bone quality to pick bone mass levels, maintain skeletal muscle and body fat mass in the elderly.
