Physical injuries not only play a large role in individuals that regularly play a sport, but in individuals that are physically active across a large variety of non-sports oriented activities as well. The ability for a physical injury to alter the quality of life can be devastating to the individual and effect not only their physical capabilities, but their mental outlook, attitute, and stability as well.
It is important that anyone involved in physical activity learns to "listen to" and be "in tune" with their bodies, as well as understanding the difference between "good" pain and "bad" pain. In other words, there can be a certain level of pain associatd with performing a physical activity that is to be expected, and there can be pain that is not normal and is a sign that an injury is occurring or has occurred.
In addition, individuals that regularly exercise may experience soreness, tightness, or fatigue a day or two after a workout. Again, this can be normal as the body requires time to re-build and replenish itself. However, if an individual feels pain in their ankle for 3 or 4 days after an aggressive run it may be a sign that an injury has occurred. In the event that an injury occurs, it is important to consult a medical professional as soon as possible as, if left undiagnosed and untreated, the injury may worsen and cause even greater damage. More importantly, if left untreated, the injury may elevate to a level where the individuals entire lifestyle is effected.
