PURPOSE: The aim of this study was to compare physiological and perceptual responses to progressive moderate intensity continuous exercise (MICE) between leg (LCE) and arm cycle ergometry (ACE). METHODS: Seventeen active men and women (age and percent body fat = 26 ± 7 yr and 18 ± 3 %) initially performed graded exercise on each modality to assess maximal oxygen uptake (VO2max) and peak power output (PPO). Using a randomized crossover design, they subsequently performed 45 min of MICE consisting of three 15 min bouts at 20, 40, and 60 % PPO on each modality. Gas exchange data (VO2, VCO2, …

Creatine monohydrate supplementation is broadly substantiated to elicit both favorable ergogenic and health-associated advantages amidst vast demographics. Nevertheless, its impacts on human cardiovascular outcomes are hitherto undescribed in generally healthy populations. Furthermore, females are largely underrepresented in the ergogenic creatine literature and their potentially differential cardiovascular responses are unknown. PURPOSE: to determine whether young, healthy females would glean discernible hypertrophy and enhanced performance, commensurate to favorable post-resistance training cardiovascular parameters and relative to placebo-matched controls across a four week training timeline. METHODS: Twenty-eight resistance trained women (25.5±6.1 years) were randomly assigned to supplement creatine monohydrate (CRE; 5g creatine monohydrate …
