5. Error: Stretching ligaments, especially if your joints have normal range of motion.
Stretching ligaments leads to loose-jointedness and can be effectively applied only with children. In adults, an age-related increase in the rigidity of collagen fibers makes any stretches aimed at elongating ligaments hazardous. When children stretch ballistically or statically, their muscles do not contract as strongly as an adult's, and their softer ligaments can be stretched (Raczek 1991). If a ligament is stretched more than six percent of its normal length, it tears. There is no need to stretch ligaments to perform even the most spectacular gymnastic or karate techniques. The normal range of motion is sufficient. Stretching ligaments destabilizes joints and thus may cause osteoarthritis (Beighton et al. 1983).
