The Chronic and Acute Effects of Exercise Upon Selected Blood Measures.
Roitman, J. L.; Brewer, J. P.
This study investigated the effects of chronic and acute exercise upon selected blood measures and indices. Nine male cross-country runners were studied. Red blood count, hemoglobin, and hematocrit were measured using standard laboratory techniques; mean corpuscular volume (MCV), mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentrations were calculated using standard formulas. Samples were taken during the preseason, at two times during training, once after the season was completed, and after two weeks of de-training. Analysis of chronic effects show that all measures except MCV increased during the season. The analysis of acute effects shows consistent hemoconcentration after both types of conditioning session (intermittent and continuous). The increases were similar for each type of session, showing little difference due to form of exercise. (Three tables of data are presented.) (JB)
