Detailed Description
Creatine monohydrate is a popular nutritional supplement with athletes involved in sports involving strength and power. When creatine is orally ingested it combines with inorganic phosphate to form phorylcreatine (PCr) in skeletal muscle . Adenosine Triphosphate (ATP) is the immediate source of energy in muscle - during exercise ATP is broken down to Adenosine Diphosphate (ADP) and inorganic phosphate. Duration of high-intensity exercise is limited to a few seconds based on limited ATP stores in muscle. PCr acts to re-phosphorylate ADP to form ATP so that muscle contraction can continue at high intensities. After creatine monohydrate is ingested, high-intensity exercise capacity is increased because of the increased PCr stores in muscle.
Delivra Inc. has developed a topical cream containing creatine that is designed to penetrate the skin. The study purpose is to determine whether the topical cream, at two different doses, is effective for improving muscular strength and power.
The hypotheses are that the experimental topical creatine cream will be more effective than a placebo cream for improving muscular performance and that two consecutive applications of creatine cream is more effective than a single application for improving muscular performance.
The study involves a involves a double-blind placebo-controlled parallel group design. Participants (n=132) will be randomized to receive either a low dose (3.5 mL) or high dose (7 mL) of topical creatine.
The baseline assessment involves measuring muscular power during 5 sets of 15 repetitions of knee extension on a dynamometer, with each set separated by 1 minute rest, with each leg tested separately. At least 72 hours after the baseline testing, participants will receive either a high or low dose of the topical creatine cream applied to the quadriceps of one leg. The high-dose group will receive 3.5 mL of creatine cream 30 minutes and 15 minutes to one leg (randomized) before exercise testing (i.e. the same testing as performed in visit 2). They will receive 3.5 mL of placebo cream 30 and 15 minutes to the opposite leg before testing. The low-dose group will receive placebo cream 30 minutes before testing and creatine cream 15 minutes before testing to one leg; they will receive placebo cream 30 and 15 minutes before testing on the opposite leg. Testing on each leg will involve measuring muscular power during 5 sets of 15 repetitions of knee extension on the dynamometer, with each set separated by 1 minute rest.
The primary outcomes are average and peak power output.
