Exercise training and regular physical activity increase oxidation of fat. Enhanced oxidation of fat is important for preventing lifestyle diseases such as hypertension and obesity. The aim of the present study in rats was to determine whether intake of dietary soya protein and exercise training have an additive effect on the activity and mRNA expression of enzymes involved in skeletal muscle fatty acid oxidation. Male Sprague–Dawley rats (n 32) were assigned randomly into four groups (eight rats per group) and then divided further into sedentary or exercise-trained groups fed either casein or soya protein diets. Rats in the exercise groups were trained for 2 weeks by swimming for 120mi/, 6/eek. Exercise training decreased hepatic triacylglycerol levels and retroperitoneal adipose tissue weight and increased skeletal muscle carnitine palmitoyltransferase 1 (CPT1) activity and mRNA expression of CPT1, β-hydroxyacyl-CoA dehydrogenase (HAD), acyl-CoA oxidase, PPARγ coactivator 1α (PGC1α) and PPARα. Soya protein significantly decreased hepatic triacylglycerol levels and epididymal adipose tissue weight and increased skeletal muscle CPT1 activity and CPT1, HAD, acyl-CoA oxidase, medium-chain acyl-CoA dehydrogenase, PGC1α and PPARα mRNA levels. Furthermore, skeletal muscle HAD activity was the highest in exercise-trained rats fed soya protein. We conclude that exercise training and soya protein intake have an important additive role on induction of PPAR pathways, leading to increased activity and mRNA expression of enzymes involved in fatty acid oxidation in skeletal muscle and reduced accumulation of body fat.
