Brief Summary:
Creatine is a nutritional supplement that is often ingested to improve exercise performance. The advent of a new product that is applied to the skin overlying muscle offers potential benefit, if the creatine can be targeted to specific muscles. The investigators are testing a novel creatine cream to determine the effects on human muscular performance. The investigators are assessing whether 7 days of topical creatine application is additive to orally-ingested creatine for improving muscular power (determined by knee extension).
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.
Traditionally, creatine is consumed orally as a supplement. Delivra Inc. has developed a topical cream containing creatine that is designed to penetrate the skin. The study purpose is to determine whether topically-applied creatine is additive with orally-ingested creatine for improving muscular strength and power.
The hypothesis is that topically-applied creatine is additive with orally-ingested creatine for improving muscular performance.
The study involves a double-blind placebo-controlled parallel group design. Participants (n=132) will be randomized to receive either oral creatine supplementation or placebo (21 g/d) for 7 days. One leg of each participant will be randomized to receive topical creatine (3.5 mL/d) and the opposite leg placebo for 7 days.
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. Additional measures include assessment of body composition and body water content. Participants will then receive either oral creatine (21 g/d) or placebo for 7 days. One leg of each participant will be randomized to receive topical creatine (3.5 mL/d) and the opposite leg placebo for 7 days. The same assessments as done at baseline will then be repeated after the 7 days of creatine supplementation.
The primary outcomes are average and peak power output.
