Overtraining Syndrome - This phenomena can occur when the athlete is engaged in fitness or training activities that exceed the bodies' normal psychologic and physiologic limitations. Usually an imbalance exists between exercise and the recovery period. Unfortunately, this can lead to decreased performance, insomnia, irritability, an increase in injuries and in some cases depression. To prevent this from occurring, ensure adequate rest or recovery days follow high intensity training intervals. Proper nutrition and fluid supplementation are also important.
Strains can occur from lifting too heavy a weight, swinging a gold club too far, or sprinting.
When a few fibers tear, the muscle or tendon is weakened and becomes susceptible to further tearing. More extensive muscle or tendon tears may require surgery to repair. To avoid strains, warm up and increase exercise intensity gradually. Sprains - This type of injury occurs from sudden or violent twisting of a joint. A sprained ankle is a common example.
