OVERTRAINING

Simultaneously, the athlete that is enrolled in a weight training or dance class on the same day of team practice, the individual that goes to the weight gym the same day of a team practice or similar scenario's that can lead to over-training. The concept of periodization is based on the concept of building and peaking. Even if you don't buy into the concept of periodization, we can all agree that an individual can't train hard every day.
 
Professionally I have many times treated an athlete who was forced to rest either because of an injury or for personal reasons. Upon their return to training and competing they reach a personal best. I believe that the time off allows their body to heal and the time off motivates thWe see the over-trained athlete who runs with a club and their school team em to train harder.
 
Let's break rest & recovery into different time frames:
 
1. Daily; 7 to 8 hours of sleep/night

2. Weekly; At least 1 day off/week

3. Competition; One shouldn't run too many races at one meet or race 2 times a week. Not every race has to produce a PR.

4. Seasonal; I recommend a week off between seasons. It's also a good time to replace old shoes

5. Annually; A 3 week rest will allow the body to recover and is a cure to avoid mental burnout
 
Unless you're a professional athlete and have the ability to nap during the day, avoid double workouts. These rules apply more to the younger athletes whose neuromusculo-skeletal system is not fully developed.
