Effect of a HIIT Programme vs. Extensive Continuous Training on Inexperienced Individuals

The aim of this study was to analyse the effect of high-intensity interval training (HIIT) and compare it with the effect of extensive continuous training (continuous running) on the variables of body weight, % fat and VO2max. 32 participants with no previous experience (mean ± SD: 22.37 ± 1.8 years...

Description
Summary:The aim of this study was to analyse the effect of high-intensity interval training (HIIT) and compare it with the effect of extensive continuous training (continuous running) on the variables of body weight, % fat and VO2max. 32 participants with no previous experience (mean ± SD: 22.37 ± 1.8 years of age, 65.52 ± 11.98 kg in weight, 170.66±9.95 cm in height) were randomly assigned to a HIIT group or continuous running training group with three weekly sessions for 10 weeks. The HIIT sessions lasted 20-25 minutes using functional bodyweight exercises with a work/rest ratio of 20/10 seconds. The continuous running sessions lasted 60 minutes without exceeding 70% of personal VO2max. Both groups obtained significant improvements (p < .05) in the study variables: body weight, % fat and VO2max. However, the improvement in the HIIT group was higher in the three variables which suggests it is a more efficient and effective form of training in terms of total weekly volume/time than the extensive continuous method based on continuous running.
