The mechanism of injury for a distal tendon rupture is forced contraction under eccentric load. [1] [9] A few examples of forced contraction under eccentric load include mixed-grip deadlifts (one forearm pronated and the other supinated, putting the biceps under greater load), preacher curls, and the "kingsmove" technique in armwrestling.
[2]: 73 Also, the repeated-bout effect appears even after a relatively small number of contractions, possibly as few as two. In one study, a first bout of 10, 20 or 50 contractions provided equal protection for a second bout of 50 contractions three weeks later. [2]: 70 The reason for the protective effect is not yet understood.
Treatment involves extensive hydration normally done through IV fluid replacement with administration of normal saline until CK levels reduce to a maximum of 1,000 U/L. [21] Proper treatment will ensure hydration and normalize muscle discomfort (pain), flu-like symptoms, CK levels, and myoglobin levels for patient to begin ExRx.
Tears of the biceps brachii may occur during athletic activities, however avulsion injuries of the distal biceps tendon are frequently occupational in nature and sustained during forceful, eccentric contraction of the biceps muscle while lifting. [20] Treatment of a biceps tear depends on the severity of the injury.
Biceps femoris tendon rupture can occur when the biceps femoris is injured in sports that require explosive bending of the knee as seen in sprinting.If the athlete is fatigued or has not warmed up properly he/she may suffer a hamstring strain/rupture, which is the tearing of the hamstring muscle.
“Eccentric moves are relatively intense, so giving muscles time to recover is important to avoid soreness and injury. Even once a week can bring strength gains and flexibility improvements if ...
Muscle injury (such as a large burn or surgery) can cause muscle contractures as internal scar tissue (adhesions and fibrosis) develops. Repetitive muscle injuries (e.g. sports injuries, major muscle strains) and micro-injuries (e.g. overuse injuries, minor muscle strains) can also cause this. Adhesions and fibrosis are made of dense fibrous ...
