Physiological Effects of Creatine Supplementation in Active Males

Effects of 28 Days of Different Forms of Creatine Supplementation on Muscle Creatine, Body Composition and Exercise Performance in Recreationally Active Males

This study was designed to examine how different forms of creatine impact active males.

This study examined the effects of different formulations of creatine nitrate on muscle creatine content, body composition, anaerobic exercise capacity, bench press performance and clinical chemistry panels in recreationally active males.

Inclusion Criteria:

• participants are apparently healthy and recreationally active males between the ages of 18 and 40;
• participants will need to have at least six months immediate prior history of resistance training on the bench press and leg press or squat;

Exclusion Criteria:

• participants have a history of treatment for metabolic disease (i.e., diabetes), hypertension, hypotension, thyroid disease, arrhythmias and/or cardiovascular disease;
• participants are currently using prescription medications;
• participants have a history of smoking;
• participants drink excessively (i.e., 12 drinks per week or more);
• participants have a recent history of creatine supplementation within six weeks of the start of supplementation;
