Wurst download 1.85/22/2023 All participants completed one repetition max (1RM) strength testing for leg press and bench press at baseline and week 6. Materials and methods: 64 untrained males ( n = 23) and females ( n = 41) (mean ± standard deviation age: 33.2 ± 10.0 years %fat: 31.6 ± 7.4%) were randomized to either (1) pre-post supplementation, (2) placebo, or (3) control. Purpose: To evaluate the chronic effects of pre- and post-workout supplementation on body composition and strength, and to understand sex-specific responses. There is little research evaluating the combined effects of HIRT and HIIT on body composition and strength, particularly when paired with nutritional supplementation. Introduction: Activities such as high-intensity resistance training (HIRT) and high-intensity interval training (HIIT) may be more time-efficient modes to stimulate rapid changes in performance and body composition. 3Department of Nutrition, Gillings School of Global Public Health, University of North Carolina at Chapel Hill, Chapel Hill, NC, United States.
