摘要：Objective. HIIT corresponds to the English acronym of High Intensity Interval Training, which in Spanishmeans Training in High Intensity Intervals, a name that already gives us an idea of the subject and focus that thisactivity will have.It consists of performing exercises that usually involve the work of a large number of musclegroups, so that intervals of great intensity are alternated with intervals of medium and low intensity. Followingthis dynamic, it is possible that a complete recovery between the high intensity intervals will not occur.Theexercises to be performed are very varied, including activities such as running or cycling, and also "static"exercises such as squats, jumps, pull-ups, push-ups.The aim of this investigation was to explore the effect ofhigh intensity interval training (HIIT) on weight, body mass index and body fat percentage for adults.Methods. Forty (20) physical fitness practitioners did not have any training experiences that wererandomly. The researchers took written approval from the participants.Results:The results showed statistically significant differences between the pre-and post-test for weight,BMI and BFP.Conclusion. In conclusion, we have demonstrated that HIIT conveys benefits to weight loss may besuperior to the effect of traditional continuous training. HIIT may therefore be suitable as an alternative tocontinuous exercise training in the promotion of health and weight loss, more research is needed to determineboth behavioral responses and clinical benefits over the longer term.
