The effects of pre versus post workout supplementation of creatine monohydrate on bod

Background:Chronic supplementation with creatine monohydrate has been shown to promote increases in total intramuscular creatine, phosphocreatine, skeletal muscle mass, lean body mass and muscle fiber size. Furthermore, there is robust evidence that muscular strength and power will also increase after supplementing with creatine. However, it is not known if the timing of creatine supplementation will affect the adaptive response to exercise. Thus, the purpose of this investigation was to determine the difference between pre versus post exercise supplementation of creatine on measures of body composition and strength.Methods:Nineteen healthy recreational male bodybuilders (mean ± SD; age: 23.1?±?2.9; height: 166.0?±?23.2~cm; weight: 80.18?±?10.43~kg) participated in this study. Subjects were randomly assigned to one of the following groups: PRE-SUPP or POST-SUPP workout supplementation of creatine (5~grams). The PRE-SUPP group consumed 5~grams of creatine immediately before exercise. On the other hand, the POST-SUPP group consumed 5~grams immediately after exercise. Subjects trained on average five days per week for four weeks. Subjects consumed the supplement on the two non-training days at their convenience. Subjects performed a periodized, split-routine, bodybuilding workout five days per week (Chest-shoulders-triceps; Back-biceps, Legs, etc.). Body composition (Bod Pod®) and 1-RM bench press (BP) were determined. Diet logs were collected and analyzed (one random day per week; four total days analyzed).Results:2x2 ANOVA results - There was a significant time effect for fat-free mass (FFM) (F?=?19.9; p?=?0.001) and BP (F?=?18.9; p?
