Outcomes are described as; (SBP) Systolic blood pressure, (DBP) Diastolic blood pressure, (Total BF) Total body fat, (Total FFM) Total fat˗free mass, and (Total BMC) Total bone mineral content. (B) βeta estimated change in each independent outcome. (SE) Standard error. (t-test) Student t-test. (95%CI) Denotes 95% confident interval. Bold values denote significant association at P ≤ 0.05 level. | |||||
