Male rats were raised either on a control diet (EC) or on diets supplemented with 0.15 percent (0.15EP), 0.3 percent (0.3EP), or 0.9 percent (0.9EP) Prunus mume extract for four weeks.They then did some exercise testing of these little rodents. Compared to that in EC (control) rats, serum lactate levels were significantly lower in rats fed 0.15 percent or higher levels of Prunus mume extract.
Dietary supplementation with the Prunus mume extract significantly elevated hepatic and muscle glycogen concentrations of the rats after the exercise. Prunus mume extract significantly reduced lactate dehydrogenase activity and increased citrate synthase activity in the skeletal muscles of the rats immediately after the exercise loading. What does all this metabolic effects mean? Well, taken together, these results indicate that the Prunus mume extract administered during endurance exercise training may enhance the oxidative capacity of skeletal muscle and may help promote the use of fat as a fuel during exercise.4 So, there you have it: Chinese plum helps you burn fat., as well as its extract.
