Resumen de Repercusiones sobre la presión arterial y las células progenitoras CD34+ tras diferentes tipos de entrenamiento
In the actuality there is great scientific evidence about the multiple benefits offered by physical activity and exercise in promoting and maintaining health. The correct functioning of the vascular endothelium is vital for cardiovascular health, incorporating physical exercise programs is important in primary and secondary care of atherosclerosis and cardiovascular disease. The circulating CD34+ hematopoietic progenitor cells are bone marrow-derived cells that are mobilized into the circulation and incorporated at sites of injury where they are believed to participate in vascular repair through re-endothelization, but there are contradictory results regarding the increased levels and schedule of the cells after exercise. The circulating CD34+ hematopoietic progenitor cells levels in the days following a long-distance walking exercise have not been studied, neither after 3 different types of training programs: aerobic, resistance, and a combination of both. Also, it is important to know changes in blood pressure during submaximal and maximal exercise after physical training period. This study has provided initial evidence of important medium-term changes in the circulating CD34+ hematopoietic progenitor cells levels following to single session in long endurance exercise, on the other hand, no changes in the circulating CD34+ hematopoietic progenitor cells were detected after training programs: aerobic, resistance, and a combination of both. Moreover, it found clear differences in blood pressure changes among the three training groups, with exercise programmes clearly able to decrease the blood pressure during a submaximal and maximal exercise. These results indicate than we can no longer only consider how blood pressure is affected by exercise in general, but that we must also consider the effects of different training programmes on blood pressure.
