HIIT vs continuous training in obesity prevention

Abstract

This research discusses the role of training using the High Intensity Interval Training (HIIT) and Continuous Training models with their influence in preventing weight gain or preventing obesity. Material and Methods. The research used male Wistar animals aged 2 to 3 months with a total of 27 Wistar, HIIT (n = 9), Continuous (n = 9), Control (n = 9). The HIIT training protocol uses an intensity of 90‑100% of the total maximum baseline speed with intervals of 1:1 (2 minutes on: 2 minutes off) for 15 minutes. Continuous training uses an intensity of 50‑70% of the baseline speed for 30 minutes. Controls were not given any treatment at all. The exercise procedure uses a special Wistar treadmill and the exercise is carried out for 6 weeks. Body weight was measured using a WRT type scale. Data were presented descriptively and tested pre‑post body weight differences using the paired sample T-test and tested body weight between groups using ANOVA. Result. The HIIT group experienced an increase in body weight of 49%. In the Continuous group, there was a difference between pre and post body weight which increased by 50%. In the control group, there was also a significant difference between pre and post body weight, which increased by 70%. Meanwhile, in the final body weight between groups compared with control, there was also a significant difference between HIIT vs Control (P = 0.008), Continuous vs Control (P = 0.016). Conclusion. HIIT and continuous training models can be used as alternatives to prevent weight gain. This exercise model has the same effect in terms of preventing weight gain.
