Erythrocytic System under the Influence of Physical Exercise and Training

Abstract: It is obvious that physical performance, endurance capacity and resistance to fatigue in humans are dependent upon many different factors. One factor, the oxygen carrying capacity of blood, seems to be of particular importance. This factor is mainly determined by haemoglobin concentration, number of circulating erythrocytes and the efficiency of their functions. A single bout of physical effort and, even more, repeated exercise may change the morphological indices of blood and influence the erythropoietic proc… Show more

“…In this direction, there are studies showing an increase in Hb resulting from erythrocyte destruction caused by exercise (Szygula, 1990;Weight et al, 1991;Smith, 1995), which is partly responsible for a higher production of ROS, and the consequent oxidative stress in T1. This released hemoglobin is oxidized to metahemoglobin, producing ROS, which favours lipid peroxidation and the formation of hydroperoxides (Cooper et al, 2002;Murakami and Mawatari, 2003;Bonilla et al, 2005).…”

“…The increase in reticulocytes after the race correlated with plasma cortisol but was not associated with changes in EPO, as already reported by Bodary and coworkers (3). Besides stress, hemolysis secondary to the mechanical impact of running (25) could also modulate the reticulocyte response to exercise.…”

“…Erythrocyte production was studied relative to athlete's anemia (25) and to assess the effects of intermittent hypoxic exposure on exercise performance (1). Conversely, little is known of the effects of exercise on myeloid precursors.…”

“…Blood lactate concentration increases after 400-meter freestyle swimming [25,27]. Increased lactate levels may affect erythrocyte rheological properties [33]. The present study was performed to investigate the effects of acute swimming exercise on erythrocyte aggregation and deformability.…”
