Aim: To determine bone density adaptation from multiple-of- bodyweight (MOB) compressive force with exercise apparatus designed for osteogenic loading.
Methods: Osteogenic Loading (OL) apparatus was used to isolate optimal ranges of motion allowing for axial bone loading at levels that could be MOB (force/loading measured by load cells within the OL apparatus). Optimal positions for OL were verified by analysis of force production maximization . Volunteer subjects, mean age of (+/- SD), (n=14) performed 4 specific multi-joint movements on the OL apparatus, each lasting 5 seconds. Sessions were repeated once per week.
Results: Mean peak force/loading for subjects was (+/- SD) MOB (hip/legs) and (+/- SD) MOB (spine). Since different hospitals and radiology offices were used to gather DXA data, not all subjects had both hip and spine T-scores, and weeks/sessions of using OL were not uniform, the results are presented in a case report format, depicting pre and post DXA of hip and spine. Conclusions: This MOB level of axial force has been seen to improve BMD [2, 3, 4], however has been commonly affiliated with injury. BMD improvement outcomes were observed in all subjects for one or both test sites with no instances of injury or discomfort, at levels of MOB reaching (+/- SD) MOB (hip/legs) and (+/- SD) MOB (spine). These results suggest a larger more controlled study be done to further examine the OL stimulus and adaptation.

This maybe one case but it will be hard to extract from the still murky saga courtesy of Fancy Bears and the “Jiffy Bag” where it appeared that Team Sky were arbitraging the rules on TUEs in order to administer a powerful anti-asthmatic drug ahead of Bradley Wiggins major target races and already reductive headlines like “Tour de France winner Chris Froome positive” are on TV and radio news bulletins. Certainly here is another substance that can be used and even exploited up to a certain amount and Sky’s medical team may not get too much benefit of the doubt here.
