Final answer:
The provided information does not specify the type and amount of creatine supplementation given to an athlete; nevertheless, creatine, such as creatine monohydrate and creatine ethyl ester, is useful for increasing muscle cell size and providing bursts of energy for high-intensity activities. Creatine helps to increase power output by making more ATP available during short, intense exercises.
Step-by-step explanation:
The type and amount of creatine supplementation given to an athlete over a 14-week period are not specified in the provided information. However, to understand the context, creatine is often used by athletes to increase muscle mass and power output. The skeletal formula of creatine is depicted in Figure 19.6.2, and it is important to note that creatine works by increasing cell volumization. Creatine is available in several forms including creatine monohydrate and creatine ethyl ester. These forms differ in aspects such as cost and recommended dosage.
For athletes, the main advantage of using creatine supplementations, such as creatine phosphate, is to provide quick bursts of ATP for muscle contraction during high-intensity exercises like weightlifting or sprinting. Creatine's role in energy production is crucial for activities lasting for about 8-10 seconds, after which the body relies on glycogen for ATP production.
Important Notes on Creatine Use:
- Creatine draws water into muscle cells, contributing to increased cell size without causing bloating.
- It may be beneficial to consume creatine with protein and carbohydrates for enhanced effects.
- Creatine phosphate contributes to increased explosive power output by supplying ATP at a very high rate during the initial stages of muscle contraction.
