Resistance exercise training improves glucose metabolism in mice. A The glucose tolerance test (IPGTT) was measured after glucose injection (1 g/kg/BW), SED-HF; n = 9, REX-HF; n = 8. Values are presented as mean ± SEM. Significant differences were determined using an unpaired two-tailed Student’s t-test. *p < 0.05. B Correlations between glucose tolerance and grip strength, n = 5–8. C Correlations between glucose tolerance and hanging time. n = 5–8. Statistical differences and r values were determined using Pearson’s correlation coefficient analysis. *p < 0.05. D gWAT were visualized using IF with an anti-GLUT4 antibody; n = 3 for all groups
