Zucker Diabetic Fatty rats (ZDF) presented a higher mean body weight than Lean animals (**P≤ 0.005). Plantaris muscle was atrophied in sedentary (n= 8) and trained (n= 8) ZDF rats when compared to Lean (n= 9) animals (***P≤ 0.001). Epididymal white adipose tissue (EWAT) was significantly increased in sedentary and trained ZDF rats when compared to Lean animals (***P≤ 0.001). Glycaemia (mg dl−1) was significantly increased in sedentary ZDF rats when compared to Lean animals and trained ZDF (*P≤ 0.05). Exercise training prevented any significant increase in glycaemia in trained ZDF rats when compared to Lean animals. n/a: non applicable. Data are means ±s.e.m.
