Rest and Recovery
Most athletes know that getting enough rest after exercise is essential to high-level performance, but many still over train and feel guilty when they take a day off. The body repairs and strengthens itself in the time between workouts, and continuous training can actually weaken the strongest athletes.

Rest days are critical to sports performance for a variety of reasons. For top level athletes rest is physically necessary so that the muscles can repair, rebuild and strengthen. A premier athlete can not ask their body to perform a high, intense level if it has not had adequate time to rest and recover.

Daily Rest and Recovery
Rest: Time is one of the best ways to recover (or heal) from just about any illness or injury and this also works after a hard workout. Your body has an amazing capacity to take care of itself if you allow it some time. Resting and waiting after a hard workout allows the repair and recovery process to happen at a natural pace. It's not the only thing you can or should do to promote recovery, but sometimes doing nothing is the easiest thing to do.
Stretch. If you only do one thing after a tough workout, consider gentle stretching. This is a simple and fast way to help your muscles recover.
Cool Down: Cooling down simply means slowing down (not stopping completely) after exercise. Continuing to move around at a very low intensity for 5 to 10 minutes after a workout helps remove lactic acid from your muscles and may reduce muscles stiffness.
Eat Properly: After depleting your energy stores with exercise, you need to refuel if you expect your body to recover, repair tissues, get stronger and be ready for the next challenge. This is even more important if you are performing endurance exercise day after day or trying to build muscle. Ideally, you should try to eat within 60 minutes of the end of your workout and make sure you include some high quality protein and complex carbohydrate.
Replace Fluids: You lose a lot of fluid during exercise and ideally, you should be replacing it during exercise, but filling up after exercise is an easy way to boost your recovery. Water supports every metabolic function and nutrient transfer in the body and having plenty of water will improve every bodily function. Adequate fluid replacement is even more important for endurance athletes who lose large amounts of water during hours of sweating.
Get Lots of Sleep. While you sleep, amazing things are taking place in your body. Optimal sleep is essential for anyone who exercises regularly. During sleep, your body produces Growth Hormone (GH) which is largely responsible for tissue growth and repair.

Practice Rest and Recovery
During practice players will be given periodic short breaks. It is expected that they will REST during this time, hydrate, and if necessary refuel.

Event Rest and Recovery

Rest and Recovery during competition, particularly tournaments is critical.
