Interval Training Is Efficient In Improving VO sub(2max) In Runners

PURPOSE: To compare the effects of interval and constant velocity training in runners. METHODS: Twenty seven recreational endurance runners were matched into the interval training group (IT-group, n = 14) and constant velocity training group (CT-group, n = 13). All runners went through a 10-week endurance training program, which included two high intensity training sessions per week. RESULTS: All runners improved their velocity at VO sub(2max) (2.7%, p%lt; 0.001), VT (4.2%, p < 0.001), LT (3.6%, p < 0.001) and vMART (1.8%, p < 0.01) but they could not improve their RE and there were no significant differences between the groups (p < 0.05). The main novel finding of the present study was that IT-group improved their VO sub(2max) in l/min (4.6%) more than CT-group (0.6%, p < 0.05).
