The Effects of Maximal Aerobic Training on some Cardiovascular Factors and Maximum Oxygen Consumption while Training in Upper and Lower Extremities.

ABSTRACT: present study attempts to compare the effect of maximal aerobic training on some cardiovascular factors and maximum oxygen consumption with training in upper and lower extremities. The subjects of the study consisted of 18 high school students. The mean of age, weight and body mass index were 16.60±1.5 years, 175.9±4.7cm, 67.1±8.1kg, 21.6±1.8kg per square meter, respectively, and also the mean heart rate and blood pressure measured at rest condition were 70.9±7 beat per minute and 10.6±0.7 mile meter/mercury, respectively. Aerobic test for upper and lower organs was based on casmed k4b2 protocol using ergo meter bicycle. To compare the means obtained, the implicit correlated statistics method of paired T-test and Wilcoxon signed_rank test were used. It revealed a significant difference in maximum oxygen consumption, heart rate, systolic blood pressure and myocardial oxygen cost between upper and lower organs (p < 0.05). The amount of heart rate, systolic blood pressure, and myocardial oxygen cost in upper extremity is greater than those of the lower extremity while the amount of maximum oxygen consumption was greater for lower extremity compared with the upper extremity.
