CROSSFIT-BASED HIGH-INTENSITY POWER TRAINING IMPROVES MAXIMAL AEROBIC FITNESS AND BODY COMPOSITION MICHAEL M. SMITH,ALLAN J. SOMMER,BROOKE E. STARKOFF, AND STEVEN T. DEVOR Health and Exercise Science, The Ohio State University, Columbus, Ohio ABSTRACT INTRODUCTION Smith, MM, Sommer, AJ, Starkoff, BE, and Devor, ST. Crossfit- igh-intensity interval training (HIIT) has been based high-intensity power training improves maximal aerobic used as an alternative to traditional endurance fitness and body composition. J Strength Cond Res 27(11): H training for the improvement of aerobic fitness. 3159–3172, 2013—The purpose of this study was to examine HIIT is practical for many individuals due to the the effects of a crossfit-based high-intensity power training (HIPT) minimal time commitment required when compared to tra- ditional continuous endurance training. A relatively new var- program on aerobic fitness and body composition. Healthy sub- iation of HIIT has recently become popular and incorporates jects of both genders (23 men, 20 women) spanning all levels of high-intensity resistance training using varied, multiple-joint aerobic fitness and body composition completed 10 weeks of movements. This high-intensity power training (HIPT) may HIPT consisting of lifts such as the squat, deadlift, clean, snatch, also offer improvement of aerobic fitness with minimal time and overhead press performed as quickly as possible. Additionally, commitment compared with traditional aerobic training. this crossfit-based HIPT program included skill work for the HIPT has recently become popular worldwide; however, improvement of traditional Olympic lifts and selected gymnastic proponents have made many unsubstantiated claims. exercises. Body fat percentage was estimated using whole-body HIPT differs from traditional HIIT in that it includes _ plethysmography, and maximal aerobic capacity (VO2max) was a lack of a prescribed rest period, focus on sustained high measured by analyzing expired gasses during a Bruce protocol power output and use of multiple joint movements.
