Delayed onset muscle soreness (DOMS) is the pain and stiffness felt in muscles after unaccustomed or strenuous exercise. The soreness is felt most strongly 24 to 72 hours after the exercise. [1] [2]: 63 It is thought to be caused by eccentric (lengthening) exercise, which causes small-scale damage (microtrauma) to the muscle fibers. After such ...
Simple, single-joint movements, like a biceps curl, can feel natural after just a few sessions. “Your brain only needs to coordinate one muscle group, so the pathways form faster,” says Rothstein.
A strain can occur as a result of improper body mechanics with any activity (e.g., contact sports, lifting heavy objects) that can induce mechanical trauma or injury. Generally, the muscle or tendon overstretches and is placed under more physical stress than it can withstand. [1]
In all athletic programs, three features should be present: (1) emphasizing prolonged lower-intensity exercise, as opposed to repetitive max intensity exercises; (2) adequate rest periods and a high-carbohydrate diet, to replenish glycogen stores; and (3) proper hydration, to enhance renal clearance of myoglobin.

A sprain is a soft tissue injury of the ligaments within a joint, often caused by a sudden movement abruptly forcing the joint to exceed its functional range of motion.. Ligaments are tough, inelastic fibers made of collagen that connect two or more bones to form a joint and are important for joint stability and proprioception, which is the body's sense of limb position and movem
Once full passive motion is regained (at usually about four to four and a half months after surgery) strengthening exercises are the focus. The strengthening focuses on the rotator cuff and the upper back/scapular stabilizers. Typically at about six months after surgery, most have made a majority of their expected gains. [citation needed]
