The aim of this study was to compare two models of aerobic exerCIse (interval & continuous) on EPO concentration in 18-23 year old males. 50 college students were selected randomly and divided to two groups. One of the groups (25 subjects) performed interval aerobic exercise for 8 weeks. They participated in 5 training sessions per week (one session per day) and the 25 subjects in the other group did continuous aerobic exercise for 8 weeks.
The EPO concentration alterations. Red blood cell count (RBC) and mean corpuscular Volume (MCV) were analyzed in subjects in pre and post testing.
Also the VOzmax of subjects was measured before and after two models of
aerobic exercise. The data showed that:
1. There was no significant different on EPO concentration before and after
interval and continuous aerobic exercise.
2. There was no significant difference on EPO concentration between interval aerobic exercise and continuous earobic exercise.
3. The effect of interval aerobic exercise on VO2max and RBC was significant, but on the MCV was not significant.
4. The effect of continuous aerobic exercise on all of the factors including EPO concentration, RBC and MCV accept VO2max was not significant.
