Creatine Case Study

Introduction Creatine is a nitrogenous organic compound found in muscles that can be obtained in the diet through animal products (Butts, J., MD, Jacobs, B., DO, & Silvis, M., MD. 2017). Creatine is most often used to enhance sports performance and is more commonly used with athletes. Creatine has become the most popular supplement after the 1992 Olympic Games in Barcelona (Butts et al. 2017). Creatine is used to increase the amount of phosphocreatine in the muscle thus delaying fatigue. Phosphocreatine helps make ATP (adenine triphosphate) from ADP (adenine diphosphate) when energy demand is high. Research has shown that creatine has an augmenting effect in muscle strength and power especially when combined with a form of resistance training
were intrigued by the effects of creatine on muscular strength and anaerobic performance after 2 and 5 days. Their aim was to see if creatine had any augmenting effects on strength and performance and if it differed depending on the amount of time creatine was supplemented. To conduct their study, 17 young volunteers were collected for a double blind prospective study. This group contained young men who were active and healthy as well as cleared for creatine loading by a physician. They were split up into a creatine (Cr) supplementation group and a placebo (Pl) group. There was no significant age, body weight or height difference between the groups (Law et al. 2009). The anaerobic power and peak power was measured using a Wingate anaerobic test on a Monark cycle ergometer. Muscular strength was measured by a 1-RM (repetition maximum) test for bench press and back squat. Along with physical measurements the study analyzed data using a Figure 1: Changes in strength between the placebo group and the Cr supplementation group.
