Values represent mean ± SEM unless otherwise indicated. p-values are based on the results of the general linear mixed model analyses. BMI, body mass index; BMC, bone mineral content; BMD, bone mineral density; P1NP, procollagen 1 N-terminal propeptide; NTX, cross-linked N-telopeptide of type I collagen; PTH, parathyroid hormone. 1 Analyses based on n = 9 participants from the TRE group who had pre- and post-intervention blood samples.
