Abstract : The study involves lower limb bone structural measurements using a dual energy x-ray absorptiometry (DEXA) system, and a set of anthropometric measurements on recruits beginning training. Measurements from fracture cases occurring during training will be compared with non fracture cases. As of September of 1996, a total of 659 female Marine Corps Recruits from Parris Island Marine Recruit Training Center were enrolled. The last group will have completed training by December 1996 although assessment may not be completed before the end of January 1997. A subset of 175 females were scanned a second time at the end of the 12 week training period to ascertain the effect of training on bone geometry. The DEXA data will also be employed to devise an objective measurement of muscle strength at the mid thigh. Although data collection except for stress fracture ascertainment is nearly complete, no conclusions can be made until all data are checked for accuracy and completeness.
