About this study
Creatine has been widely studies within the strength and conditioning background and has been seen to show positive effects on performance assess the effects of creatine on sports requiring a range of different fitness components to be successful such as football. Previous research has suggested benefits of creatine supplementation such as increasing PCr (phosphocreatine) stores to aid ATP (adenosine triphosphate) production, increasing muscle water retention resulting in enhanced protein synthesis, reduced muscle damage and anti-inflammation. Identifying supplements that are scientifically proved to aid performance can help optimise training and develop physical ability of athletes to enhance performance.

What is being measured
The primary outcome is the main question the study is designed to answer.
The effects of acute creatine supplementation on semi-pro football player speed test results following a seven-day supplementation period.
Participants will supplement creatine for a seven day period. Baseline testing will take place before supplementation using a 30m sprint test, it will be measured by the time it took to sprint the 30m (seconds). Participants will undergo the same test after following 7 days. The effects of creatine supplementation will be noted by the difference between sprint test scores (seconds).
Measured: 7 days
The effects of acute creatine supplementation on semi-pro football player countermovement jump (power) results following a seven-day supplementation period.
Participants will supplement creatine for a seven-day period. Baseline testing for power will take place before supplementation using a countermovement jump. Participants will undergo the same test after following 7 days. The effects of creatine supplementation will be noted by the difference between countermovement jump scores (power).
Measured: 7 days
The effects of acute creatine supplementation on semi-pro football player lower limb strength test results completed through a 5-RM leg press test following a seven-day supplementation period.
Participants will supplement creatine for a seven-day period. Baseline testing will take place before supplementation using a 5-RM leg press, it will be measured by the maximal amount of weight used to complete five reps on the leg press (kg). Participants will undergo the same test after following 7 days. The effects of creatine supplementation will be noted by the difference between the maximal amount of weight used to complete five reps on the leg press (kg)t test scores (seconds).
Measured: 7 days
