Abstract
Background and Study Aim. Aerobic exercise improves fitness and quality of life and decreases mortality rate. Existence study determined the central hemodynamic adaptation after 8 weeks moderate-intensity continuous countryside jogging in non-athlete male. Material and Methods. Twenty-four untrained healthy male students (aged 20-22 years) volunteered and randomly divided into two groups: continuous training (CTG; n=12) and control (CG; n=12). Training program was countryside jogging for 45 min at 65-70% of Maximum Heart Rate (MHR), 3 days/week for 8-weeks performed. The CG group remained sedentary during the study period. Maximal oxygen consumption (VO2max) obtained using the step-test. Standard medical method impedance cardiograph was performed for hemodynamic parameters, during resting and after step-test conditions, before and after the study period. Results. Using t-test, after eight weeks: the resting heart rate (HR) in CTG group significantly decreased (P≤0.05). The systolic blood pressure (SBP) in CTG group decreased significantly at rest and after workload (P≤0.05). The diastolic blood pressure (DBP) did not change in both groups (P>0.05). The stroke volume (SV) increased significantly in CTG group at rest and after workload (P≤0.05). The cardiac output (CO) did not change in both groups (P>0.05). The cardiac output (CO) did not change in both groups (P>0.05). The VO2max absolute and relative increased significantly in CTG group (P≤0.05). Significant difference between groups in SBP, SV, SVR and VO2max (absolute and relative) (P≤0.05). Conclusions. 8 weeks moderate-intensity continuous countryside jogging can improve the cardiac function and VO2max in selected healthy male. The regular exercise of aerobic with moderate intensity causes positive developments in systolic and diastolic blood pressures.Keywords
