A strain is an acute or chronic soft tissue injury that occurs to a muscle, tendon, or both. The equivalent injury to a ligament is a sprain. [1] Generally, the muscle or tendon overstretches and partially tears, under more physical stress than it can withstand, often from a sudden increase in duration, intensity, or frequency of an activity.
A strain is a type of acute injury that occurs to the muscle or tendon. Similar to sprains, it can vary in severity, from a stretching of the muscle or tendon to a complete tear of the tendon from the muscle. Some of the most common places that strains occur are in the foot, back of the leg (hamstring), or back. [2]
These range from mild sprains and lacerations to joint dislocations, broken bones and severe neck or head injuries. Trampoline deaths are rare, but they do occur. Most trampoline injuries occur in ...
Injury can be described as a ‘mechanical disruption of tissues resulting in pain.' [13] Despite the fact tissues can self-repair, muscle degradation occurs after repeated and prolonged use. [13] Overuse and strain injuries can occur at work, physical activity and daily life. [11]
Strain vs. Time graph for the three stages of creep. Strain slowly rises up and almost becomes constant from a constant stress on a viscoelastic material. Like cartilage, it will deform or strain, from constant stress. The strain deformation is slow, but eventually too much stress will increase it.
It can be easy to use soreness as an excuse to jumble up your gym routine. But the saying “no pain, no gain,” may have some truth to it. Below, fitness experts explain how to work (and rest ...
Excessive tensile strength can overstretch a muscle, causing a strain. Strains may present with torn muscle fibers, hemorrhaging, or fluid in the muscles. Severe muscle injuries in which a tear extends across the muscle can cause total loss of function. Penetrative trauma can cause laceration to muscles, which may take an extended time to heal.
Hamstring pulls, ligament tears and ankle sprains can be as formidable an opponent for NFL teams as a high-scoring offense or stingy defense. “There’s a 100% injury rate in the NFL,” seven ...
