The p-value for “baseline” describes the baseline differences between the healthy (n=28) and IR (n=16) groups. “Time” shows all healthy and IR men after training. “Time*IR” demonstrates whether there is an interaction between the pre–post change and health status. All the data are presented as model-based means (95% CI). The values are model-based means and CIs translated into the original unit.
Bold values are statistically significant.
*Logarithmic transformation has been done to the variables to achieve the normal distribution.
†Square transformation to the variables to achieve the normal distribution.
BMI, body mass index; f-FFA, fasting free fatty acid; HbA1c, glycated hemoglobin; HDL, high-density lipoprotein; IR, insulin resistance; LDL, low-density lipoprotein; M-value, whole-body insulin sensitivity; SAT, subcutaneous adipose tissue; VO2peak, maximal aerobic capacity.
