The benefits of creatine monohydrate as a supplement is helping to increase your maximum power output (1). The reason for this is because it will rapidly reproduce your ATP system as it is specific with your training (2).
This supplement is most effective during short duration (1-10 seconds) of maximum effort (3). This supplement will not be effective for prolonged exercise that involves multiple repetitions.
Creatine Monohydrate will help reproduce your ATP system during high-intensity exercise. This supplement is meant to be taken for activities that involve short duration, max effort exercises, that last anywhere from 2-10 seconds.
Another example is if you were to build up to 90% of your maximum bench press, for 5 sets of 3 repetitions. Creatine Monohydrate will help with your recovery between these sets.
For example, if you were to perform box jumps for 3 sets of 5 repetitions at a reasonable height, and rest for 2 minutes in between sets, ATP would be the primary source of energy being used.
Creatine Monohydrate would be beneficial for Olympic Weightlifting, Powerlifting, or short-duration power exercises. Anything that is fast and explosive, Creatine Monohydrate will be applicable for a scenario like this.
