| ABSTRACT
Background and Aim: Considering the sophisticated responses of cardiovascular system to different types of body exercises, dealing with this system and the effect of exercise on it has assumed an added importance. The aim of this study was to compare the effect of two types of exercise, arm cranking and leg cycling, on cardiovascular, metabolic and hematologic factors.
Material and Methods: After obtaining informed consent 10 non athlete female students with a mean age of 25±2.69 years and mean height of 161.75±5.5cm participated in this study. They completed four experimental testing sessions (two maximal oxygen consumption test on a cycle ergometer and arm cranking to assess variations in respiratory gases and heart rate by using ergometer cycling and arm cranking vo2max, and two sub-maximal exercises including warm up for 5 minutes and body exercise on cycle ergometer or arm cranking with 70% of maximum O2 consumption or 75-80% of maximum heart rate, for 30 minutes. Then the subjects took a 30 min rest in the sitting position. Heights and weights of the subjects were measured before exercise. Before and after exercise and after 30 min rest in sitting position, heart rate and blood pressure were recorded and blood samples were collected for measurement of blood lactate concentration, RBC, Hb, Hct, MCV, MCH and MCHC.
Results: No differences were found between the two types of exercises in regard to the HR, RBC, Lac, HG, Hct, MCV and MCHC but there were significant differences in relation to BP and MCH (P=0.013 and f1.9 =9.385 for blood pressure P=0.046 and f1.9=5.372 for MCH).
Conclusion: The results indicated no differences in the cardiologic, hematologic and metabolic factors during exercises with similar relative intensity. But we found a higher BP after arm cranking and an increase in MCH after leg exercise. Also, there were significant differences in all parameters except HG and MCH, before and after exercise.
