Abstract

Objectives Isolated whey protein (IWP) can decrease body fat compared with other protein sources. The present study verified the effects of high protein diet (HD) containing IWP on several parameters of rats subjected to resistance training (RT). Methods Thirty-two male Wistar rats (60 days of age) were separated into four groups (n = 8/group): sedentary normoproteic (IWP 14%; SN); sedentary hyperproteic (IWP 35%; SH); trained normoproteic (IWP 14%; TN), and trained hyperproteic (WPI 35%; TH). Results Relative tissue/organ weight (g): perirenal and retroperitoneal adipose tissues were lower in SH and TH compared with SN (no difference to TN); omental and subcutaneous adipose tissues were higher in SN compared with SH. Epididymal adipose tissue was higher in SN compared with other groups. Heart weight was higher in TH compared with TN and SN, but not SH; kidney and liver higher in TH and SH compared with SN and TN; gastrocnemius lower in SN compared with other groups; soleus higher in SH in relation to other groups. The triglycerides levels (mg/dL) was reduced in the TH groups compared with SH, TN, and SN. There were no changes both in the concentrations of adiponectin and leptin and in the protein expression of GLUT-4 and p70s6k. Conclusion HD containing WPI improved body composition, increased the weight of the heart, kidneys, liver and gastrocnemius and soleus muscles; however, this diet maintained the normal histomorphology of muscle and liver and, when associated with RT, reduced the serum levels of triglycerides.
