BACKGROUND AND AIMS: This research aimed to assess the effectiveness of high-intensity interval training (HIIT) and high-intensity functional training (HIFT) on appetite-related hormones (Ghrelin, peptide tyrosine-tyrosine (PYY), and glucagon-like peptide-1(GLP-1)), appetite perception, and anthropometric measures in overweight and obese young men.
METHODS: Thirty male participants (age: 22.6 ± 1.7 years; weight: 101.4 ± 7.4 kg; body mass index (BMI): 31.1 ± 2.3 kg/m2) were randomly allocated into HIIT (n = 10), HIFT (n = 10), and control groups (con) (n = 10). The intervention groups received supervised training three times a week for 8 weeks, including running-based HIIT based on maximal aerobic speed (MAS) or HIFT (six bodyweight exercises). Training intensity in both groups was monitored using BORG-CR10 perceived exertion scale (RPE). Measurements were taken at baseline and after an 8-week training period. A mixed ANOVA analysis was used to analyze the data.
RESULTS: HIIT and HIFT protocols significantly increased plasma levels of PYY, GLP-1, feeling of hunger, and improved body fat percentage (BF%), waist and hip circumference, VO₂max, and vVO₂max compared to the control (p < 0.05). However, there were no significant changes in ghrelin levels (p = 0.53), appetite ratings (fullness (p = 0.48), satiety (p = 0.72), and desire to eat (p = 0.20), weight (p = 0.14), and fat-free mass(FFM) (p = 0.11). Additionally, BMI, and fat mass (FM) decreased significantly in the HIFT group, compared with the control (p < 0.05).
CONCLUSION: Overall, the findings of this study indicated that HIIT and HIFT increased fasting levels of GLP-1 and PYY, heightened hunger perception, and improved body composition and performance. HIIT showed relatively greater percent changes in PYY, GLP-1, feeling of hunger, and performance, while HIFT had larger percent changes in anthropometric outcomes.
