Effects of a pre-season interval training on maximal oxygen consumption and mean velocity in professional footbal players
Abstract
During footbal game players can cover a distance of approximately 10 to 12 km, in a mean intensity proximal to anaerobic threshold. The objective of the present study was to evaluate the efficiency of a pre-season complementary interval training of four weeks on VO2max and mean velocity in professional soccer players. 17 male players aged 23 ± 3.3 years old were selected. Before and after the intervention a 2400m test was performed for VO2max estimation. The interval training consisted of 4 running sets lasting 4 minutes at mean velocity obtained in the 2400m test, with active recovery of 3 minutes at 75% of the mean velocity. To verify the difference between the two moments, paired Student t test was done, with p≤0.05. With regard to VO2max, there was a mean increase of 5.4% or 2.61 ml/kg/min-1 (p=0.02); 5.3% or 7.59 ml/kg-0.75/min-1 (p=0.03), after four weeks of training in comparison with pre-training values. On the other hand, in VO2max expressed by l/min no statistical significant difference was observed between the pre and post-test. Mean velocity presented a significant increase of 5.2% from pre to post-test (p=0.02). It was concluded that the additional interval training protocol of four weeks was efficient in increasing VO2max and mean velocity. These results are interesting in practice, due to little available time to improve velocity and aerobic capacity in the initiation of the season.
