Body Composition And Strength Changes Following 16-weeks Of High-intensity Functional Training.: 3606 Board #45 June 4, 8: 00 AM - 9: 30 AM

PURPOSE: The purpose of this study was to examine changes in body composition and strength among apparently healthy individuals following 16-weeks of HIFT. METHODS: 53 individuals originally signed up for the study. Testing sessions included pre and post measures for body composition (Dual-Energy X-Ray Absorptiometry) and strength (5RM Front squat). Training included participation in HIFT a minimum of twice a week for 16-weeks. RESULTS: 26 individuals (49%) completed the 16-week program and provided all required measures. Repeated measures analysis of variance revealed no gender effect on strength or body composition outcomes. Paired-sample t-tests showed significant improvements in the front squat (Males - Pre: 86.87 ± 19.68 kg, Post: 95.71 ± 19.96 kg; p \u3c 0.001, Females - Pre: 48.97 ± 9.24 kg, Post: 57.02 ± 10.27 kg; p \u3c 0.001), as well as a decreases in total body fat percentage (Males - Pre: 24.49 ± 7.49 %, Post: 22.87 ± 6.63 %; p \u3c 0.05, Females - Pre: 31.29 ± 7.29 %, Post: 30.08 ± 8.33 %; p \u3c 0.05). CONCLUSIONS: High-Intensity Functional Training seems to be an appropriate exercise modality among apparently healthy individuals to significantly improve strength and body composition after 16-weeks of training
