Whereas IL-@ levels remained similar to baseline levels after one set of resistance exercises ( @ min , P = @ ; @ min , P = @ ) , IL-@ levels were > baseline levels at @ min post-exercise after a two-set exercise trial ( @ @ pg/ml , P = @ ) and doubled at both @ min ( @ @ pg/ml , P = @ ) and @ min ( @ @ pg/ml , P = @ ) post-exercise after the three-set resistance exercise trial .
