Effects of exercise on plasma nonesterified fatty acids and free amino acids in Arctic char ( Salvelinus alpinus)
Abstract The plasma nonesterified fatty acids (NEFA) and free amino acids (AA) of exercised and rested Artic char ( Salvelinus alpinus ) were measured. Total nonesterified fatty acids, total saturated fatty acids and total monoenes were significantly elevated in the plasma of the exercised group. Pl...
