A recent study examined the performance of cyclists who were going on reduced sleep. One group had 8-10 hours sleep, while the other got only four hours of sleep per night.
Not surprisingly, the sleep deprived cyclists were exhausted sooner and had less power.
You need sleep. It affects concentration, learning, and performance of muscle fibers. Sufficient sleep can also help prevent chronic disease.
Muscle recovery, replacement, repair and rebuilding takes place when you are sleeping.
Get at least eight hours of sleep per night. Try to get 10 hours when you've put your body through a big workout. Train your body to expect sleep when you hit the sack.
Dr. John Higgins advises on how to be a top notch athlete with plenty of sleep.
