Overview of load carriage exercise testing protocol.
aProcollagen type 1 N-terminal propeptide, bone-specific alkaline phosphatase, beta carboxy-terminal cross-linking telopeptide of type 1 collagen, albumin-adjusted calcium, ionized calcium, 44Ca:42Ca, phosphate, intact parathyroid hormone, 25-hydroxyvitamin D, 1,25-dihydroxyvitamin D, 24,25-dihydroxyvitamin D, luteinising hormone, follicle stimulating hormone, oestradiol, testosterone, and sex hormone binding globulin will be measured before load carriage.
bProcollagen type 1 N-terminal propeptide, beta carboxy-terminal cross-linking telopeptide of type 1 collagen, ionized calcium, albumin-adjusted calcium, phosphate, intact parathyroid hormone, sclerostin and osteocalcin will be measured at 0 and 120 min during load carriage, then 30 and 90 min after load carriage. 44Ca:42Ca will be measured at 120 min during load carriage.
cProcollagen type 1 N-terminal propeptide, beta carboxy-terminal cross-linking telopeptide of type 1 collagen, ionized calcium, albumin-adjusted calcium, phosphate, and intact parathyroid hormone will be measured at 20, 40, 60, 80 and 100 min during load carriage, and 15 and 60 min after load carriage.
