摘要：Teixeira AO, Franco OS, Borges MM, Martins CN, Guerreiro LF, da Rosa CE, Paulitsch FS, Perez W, Silva AMV, Signori LU. The Importance of Adjustments for Changes in Plasma Volume in the Interpretation of Hematological and Inflammatory Responses after Resistance Exercise. JEPonline 2014;17(4):72-83. This study evaluated hematological and inflammatory alterations resulting from an acute session of resistance exercises (RE) and corrected them by plasmatic volume adjustments. Subjects consisted of 31 men who were not practicing bodybuilding. The RE session consisted of 4 sets of 10 repetitions maximum for each exercise (extensor bench, the squat and leg press) with an interval of 1 min between sets and 2 min between exercises. The concentration of erythrocytes, platelets, total leukocytes (and fractions), ultrasensitive CRP, creatinine kinase (CK), and fibrinogen was evaluated in the blood before (basal) and after the RE. Plasmatic volume alterations were calculated by hematocrit variations. Immediately after the RE, a rise was observed in erythrocytes (6%), platelets (20%), total leukocytes (25%), segmented neutrophils (25%) and rods (18%), monocytes (44%), lymphocytes (17%), CK (15%), and CRP (23%). Percent change in plasma volume was -7.5% (P<0.001). After adjustment by the reduction of plasma volume, the erythrocytes, neutrophils rods, lymphocytes, CK, and CRP revealed values similar to basal levels (P>0.05). Plasmatic volume adjustments interfered in the interpretation of leukocyte and inflammatory response immediately after the RE.
