Abstract:

The sharp rise in physical demands initiated during basic training all too frequently will precipitate stress fractures in the lower appendicular skeleton of new recruits. During peacetime, stress fractures are by far the most common physical injury in the military population, and are responsible for the militarys greatest drain of both lost recruit time and medical expense. The objective of this three year research program is to study the etiology of the stress fracture lesion, and isolate any aspects of a physical regime which may exacerbate this condition. To perform this mission, we are persuing two parallel experimental protocols a the effect of muscle fatigue on bone strain distributions and, b the effect of repetitive cyclic loading on bone remodeling. The summation of these two protocols has already provided unique insight towards the effect of new strain regimens on skeletal remodeling, and almost certainly will isolate and identify specific activities which may accelerate the pathogenesis of this condition. Keywords Stress physiology, Bone fractures, Fatigue physiology.
