Resistance, jump training increased BMD in men
Bone mineral density of the whole body and lumbar spine in men with low bone mass was increased with resistance training and jump training, according to recent study findings published in Bone.
“This study is novel because it is the first to demonstrate the efficacy of exercise-based interventions to increase BMD in middle-aged men with low bone mass who are otherwise healthy,” the researchers wrote. “The biological and clinical significance of these results can be appreciated only if one considers that bone loss occurs with normal aging.”
Pamela S. Hinton, PhD, of the department of nutrition and exercise physiology at the University of Missouri, and colleagues evaluated physically active men (mean age, 44 years) with osteopenia of the hip or spine who underwent 12 months of resistance training two times per week (n = 19) or jump training three times per week (n = 19) to determine the effect of each on BMD and bone turnover markers.
After 6 months of resistance training or jump training, BMD increased by 0.6% and was maintained at 12 months. Lumbar spine BMD also increased after 6 months by 1.3% and was maintained at 12 months. No significant differences were found in whole body and lumbar spine BMD between the two groups after training.
A 0.8% gain in total hip BMD at 6 and 12 months was found only with resistance training.
“In summary, the results of the present study suggest that [resistance training] or [jump training] interventions are safe and effectively increase BMD, particularly of the lumbar spine, in men with low bone mass,” the researchers wrote. “These results have clinical implications, as exercise may be the appropriate ‘prescription’ for some individuals with low bone mass. Which intervention should be prescribed to improve bone health depends on the individual patient’s current hip and lumbar spine BMD, activity patterns, exercise preference, as well as time and equipment constraints.” – by Amber Cox
