Joint stability and mobility have long been regarded as opposites. Increased mobility would result in a decrease of stability and vice versa. The focus on extremes gave rise to this erroneous way of thinking. Joint laxity absolutely compromises stability, and in a rigid joint that can barely move past its neutral zone, ligament and membrane stretch as a result of extreme range of motion is less likely to occur. But joint laxity and rigidity are opposite from good, clean full range of motion joint movement and both augment the risk of injuries in sports (Taimela et al. 1990; Vaishya and Hasija 2013). Soccer, identical to most other sports, requires the expression of both stability and mobility. Imagine the ankle, knee, and hip angles of a soccer player changing direction at high speed and the forces that these joints simultaneously have to absorb and produce. Olympic weightlifters and gymnasts are known to be the most flexible athletes in the Olympics, while both groups of athletes require a great amount of stability, strength, and power to be successful in their sport.
