Hemoglobin, hematocrit and plasma volume variations following combined sprint and strength: Effect of advanced age

The study investigated the effect of combined sprint and resistance training (CSRT) on red blood cell (RBC) count, hemoglobin (Hb), hematocrit (Hct), plasma volume (PV) variation at rest and during exercise. Twenty-eight moderately trained were randomly assigned into a young trained (YT), young cont...

Description
Summary:The study investigated the effect of combined sprint and resistance training (CSRT) on red blood cell (RBC) count, hemoglobin (Hb), hematocrit (Hct), plasma volume (PV) variation at rest and during exercise. Twenty-eight moderately trained were randomly assigned into a young trained (YT), young control (YC), middle-aged trained (MAT), and middle-aged control (MAC) group. Before (P1), and after (P2) CSRT, blood samples were collected at rest and after exercise. At P1, Hct was significantly (P
