Data are presented as mean ± standard deviation (SD). Significant p < 0.05 are indicated in bold. †Denotes that data were transformed for statistical analysis. Metabolic characteristics were measured on BDC-5 and HDT59. CTRL, control group; JUMP, jumping countermeasure group; Time, main effect of time; Int, main effect of intervention; T*Int, time*intervention interaction effect; Glucose0, fasting glucose; Glucose120, glucose concentrations 120 min after the glucose load; Insulin0, fasting insulin; Insulin120, insulin concentrations 120 min after the glucose load; NEFA, non-esterified fatty acids; TG, triglycerides; CHOL, total cholesterol; HDL, high-density lipoprotein cholesterol; LDL, low-density lipoprotein cholesterol.
