Aim: This research is to determine the effects of extensive and intensive interval training practiced in different rest interval and in the same intensity on VO2max and anaerobic threshold and on blood parameters.
Material and Methods: 20 male subjects, between 18–22 ages, are participated in the study. They are randomly separated two groups. One of them (n=10) did intensive interval training (IIT), the other one (n=10) did extensive interval training (EIT). EI and II training were applied to participants thought 7 weeks and 3 days per a week and the volume of the daily training, intensity %75, is totally 2800–3000m. We tested the subjects at weights, BMI, Fat %, Fat Mass, VO2max, anaerobic threshold, hemogram and some of the biochemical tests before and after the training.
Results: There were significant increase (p<0.05) in the capacity of VO2max and anaerobic threshold at EIT. There were significant increases in the subgroup of erythrocyte; HCT (p<0.05), HGB, MCH, MCHC, RDW–CV and RDW–SD (p<0.01) at EIT. There was significant decreases in the subgroup of leukocyte; LYMPH, in the subgroup of thrombocyte; PCT and in the biochemical analysis; HDL (p<0.05) at EIT. No significant differences were found between before and after IIT in the capacity of VO2max. and anaerobic threshold. There was significant decreases in the subgroup of leukocyte; GRAN, in the subgroup of thrombocyte; PLT and PCT (p<0.05) at IIT. There were significant increase in the subgroup of erythrocyte; MCV and in the biochemical analysis; glucose (p<0.05) at IIT.
Conclusion: EIT has a decisive effect on the capacity of VO2max and anaerobic threshold. EI and II training has increased or decreased the level of some blood parameters.
