The Response of a Bone Resorption Marker to Marine Recruit Training

Abstract

Significant bone resorption took place at the end of Marine recruit training due to accumulation of weight-bearing exercise throughout training and the increase in marching toward the end.

Self-reported load carriage injuries of military soldiers

“…This result suggests a potential impact on ARA force generation capacity, especially when considering that some trainees may have been injured to the extent that they did not complete training and as such could not report their injuries in this study. While not specific to load carriage, the literature does suggest that rates of musculoskeletal injuries are higher during the earlier weeks of military training, when untrained recruits are adapting to an increase in exercise (46)(47)(48)(49)(50). Proposed causal mechanisms for these injury patterns vary.…”

Fundamental differences in axial and appendicular bone density in stress fractured and uninjured Royal Marine recruits — A matched case–control study

“…A study in British Army recruits (n = 26) reported a reduction in two markers of bone formation, and a non-significant reduction in the bone resorption marker tartrate resistant acid phosphatase (TRAP) between the start and completion of 10 weeks of initial Army training [19]. Conversely, a study in male (n = 58) and female (n = 155) US Marine recruits measured higher concentrations of the bone resorption marker deoxypyridinoline (DPD) at the end of an 11 week training programme compared with before the start of the training programme [36]. Evans et al observed higher concentrations of serum CTx at middle and end time points, of a 4-month programme of basic recruit training, compared with baseline concentrations in n = 58 male military recruits [21].…”
