An 8-month high-intensity resistance and impact training program (HiRIT, Onero) led to greater gains in lumbar spine bone mineral density (BMD) and leg/back strength than a low-intensity Pilates-based program (Buff Bones).
These findings are from the Medication and Exercise for Osteoporosis (MEDEX-OP) trial, which included 115 postmenopausal women with low bone mass. Patients were randomly assigned to attend either the HiRIT or Pilates-based exercise program. The participants attended supervised 45-min sessions twice weekly.
HiRIT was better than the low-intensity Pilates-based exercise program for enhancing bone mass, muscle strength, functional performance, and stature, the researchers report. The low-intensity program did improve function, but to a lesser extent
Of the 115 participants, most (86) were not taking osteoporosis medicine. For the 29 women who were receiving it, the medication appeared to enhance the effect of exercise.
Melanie Fischbacher, PhD candidate, Griffith University, Gold Coast, Australia, presented these findings in an oral session at the American Society of Bone and Mineral Research (ASBMR 2021) Annual Meeting; the study was also published in the Journal of Bone and Mineral Research.
The study's senior author, Belinda R. Beck, PhD, director, the Bone Clinic, Brisbane, Australia, developed the OneroHiRIT program and has licensed it to others in Australia.
