Title Effect of load carriage on spinal compression
Bibliographic information 2011, Vol.41, p.219-223. Illus. 33 ref.
Abstract The objective of this study was to investigate the effect of various load carriage methods on spinal loading over time by measuring spinal compression. Eight male adult participants were asked to carry a load equivalent to 15% of their body weight either anteriorly or posteriorly for 20 min followed by 10 min of recovery. Their statures were measured before load carriage and every 2min after carrying the load. The sequence of loading conditions was randomized and the participants took a 20-min rest with Fowler's posture for spinal length recovery prior to each testing condition. The amount of spinal compression was found to be associated with carrying duration. Spinal compression during anterior carriage was larger than that of posterior carriage. There was a mild recovery of spinal compression after the removal of the load for both the anterior and posterior carriage conditions.
