BODYWEIGHT HIGH-INTENSITY INTERVAL TRAINING: A SYSTEMATIC REVIEW

The objective of this study consisted of describing, through a systematic review, the load control strategies and the different adaptations promoted by bodyweight high-intensity interval training. After selecting articles in the Medline/PubMed, ScienceDirect, SPORTDiscus and Scielo databases, 288 studies were found. However, after applying the inclusion and exclusion criteria only two articles were considered eligible for the systematic review. Of these, the sample of the selected studies was made up of 48 individuals, 31 female and 17 male, ranging in age from 20.3 to 20.5 years. The stimulus time of the exercise protocols used was 20 and 30 seconds, and the recovery time was 10 seconds (passive) and 4 minutes (active), while the total session time ranged from 4 to 18 minutes. Intensity in both studies was "all out", and the weekly frequency was 4 and 3 days, totaling 16 and 12 training sessions in each study. Only one study evaluated changes in body mass and no significant changes were found. In addition, discrepancies between parameters in aerobic fitness and muscle endurance were found between studies. Bodyweight HIIT (High-Intensity Interval Training) protocols use different external load parameters, but the stimulus and recovery times are common variables for the organization of training sessions, with different duration and weekly frequency between sessions, which may have influenced the different adaptations to the parameters of physical fitness between the studies.
