Analysis of Hormonal Responses to Aerobic and Anaerobic Zone Training
Journal Title: Journal of Medical Science And clinical Research - Year 2015, Vol 3, Issue 3
Abstract
The purpose of the present study was to examine and compare hGH, cortisol, plasma testosterone ,epinephrine and nor epinephrine levels following an Aerobic and Anaerobic zone training.39 male football players of age(18.08±1.09), height (172.15±4.76) and weight (61.52±7.06) were randomly distributed into three groups, aerobic zone group (n=13),anaerobic zone group(n=13) and control group(n=13). The subjects reported to the laboratory between 8-9a.m. after an overnight fast. They were instructed to avoid caffeine and alcohol consumption for 24h and not to perform any physical activity for 48h before the experimental sessions. After reporting to lab the subjects were asked to take 20 minutes rest and the resting heart rate was observed with the help of heart rate monitor (S410) tied on the chest. With the help of HRmax(220-age) and resting heart rate the training zone was calculated by using Karvonen method. In aerobic zone group the subjects performed treadmill running at 75% of HRmax and in anaerobic zone group at 85% of HRmax till exhaustion. Blood samples were obtained before and immediately after the end of exercise from the anticubital vein. All the subjects performed exercise at the same time of day to avoid diurnal variation. In the control session, the subjects did not perform any exercise but they were sitting quietly for 45 minutes while blood samples were drawn at same time points. Data analysis amongst various groups was compared by one way ANOVA. Significant differences between means were located with the Tuckey HSD procedures. Aerobic and anaerobic zone training seems to be sufficient stimulus for an acute increase in hGH,cortisol,plasma testosterone ,epinephrine and nor epinephrine concentrations where hGH and cortisol showed greater responses to high intensity exercise and plasma testosterone and epinephrine to long duration and moderate intensity exercise. These hormonal responses may create an optimal environment for the metabolic processes and improved cardiovascular functions.
