Twenty-two premenopausal women (37\u2009\u00b1\u20092\u00a0years, 68.9\u2009\u00b1\u20098.0\u00a0kg, and 1.68\u2009\u00b1\u20090.04\u00a0m) were randomly assigned to collagen (COL;\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200910) and placebo (PLA;\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200912) cohorts in a triple-blind design.
