Input (English): Question: Does four weeks one-leg training and high fat diet alter PPARalpha protein or mRNA expression in human skeletal muscle?
Answer: 4 weeks one leg knee extensor training did not affect PPARalpha protein or mRNA expression. Furthermore, higher fat oxidation during exercise after fat rich diet was not accompanied by an increased PPARalpha protein or mRNA expression after 4 weeks.
Output (English): no
