Bone scans support high-velocity resistance training in older adults

Dual-energy x-ray absorptiometry (DEXA) scans show that high-velocity resistance training increases bone mineral density in older adults, according to a study published December 7 in Bone.In a literature review of studies that included 1,203 people, DEXA scans revealed significant effects of high-velocity resistance training on bone mineral density (BMD) at the lumbar spine, total hip, and femoral neck, according to a group led by Dawn Skelton, PhD, of Glasgow Caledonian University in Scotland.“The studies included in this review suggest that incorporating high-velocity resistance training into exercise regimens contributes to the prevention of osteoporosis in older adults,” the group wrote.High-velocity resistance training (HVRT) is typically performed with lighter loads (medicine balls or barbells, for instance) at fast (≤ 1 second) concentric speeds. This refers to the rate at which the muscle shortens or contracts during lifting.The American College of Sports Medicine recommends resistance training two to three times per week and weight-bearing endurance activities three to five times per week to preserve bone health during adulthood, yet the most effective intervention is still up for debate, according to the authors.Moreover, there is growing evidence that suggests that HVRT has superior benefits on BMD compared to traditional resistance training in older adults, they added.To elucidate evidence of this potential, the group searched five major electronic database...
