title: The effect of exercise on bone mass of osteoporotic patients on fluoride treatment.
abstract: The study was conducted in order to determine the effect of exercise on osteoporotic patients with a mean age of 65 years. The majority of these patients had been on sodium fluoride for at least 2 years. Thirty-eight patients were assigned to either the hospital or home group. Nineteen were in the former group, which performed the 1 hour exercise twice weekly in the Hospital. The patients in the latter group were taught the exercises and were expected to continue them at home. The exercise protocol consisted of muscle-strengthening and aerobic activities. Bone mineral mass was determined by neutron activation analysis, which measured total calcium in the trunk and pelvis. It is expressed as a calcium bone index (CaBI), with a normal range of 0.75 to 1.2. The level of physical performance was determined by calculating the maximum oxygen uptake, VO2max, attained by a graded exercise test on the treadmill. Calcium bone index and VO2max were obtained before and after the 12.5 month study. Prior to the study, the hospital and home groups had low calcium bone index values (0.68 and 0.66 respectively). Both groups showed a significant increase in calcium bone index (p less than 0.001 for the hospital group, p less than 0.01 for the home group) after the study. When compared to the home group the hospital group was found to have a significantly higher post-study calcium bone index value (p less than 0.02).(ABSTRACT TRUNCATED AT 250 WORDS)
