Strained Left Hamstring
Straining of the hamstring, also known as a pulled hamstring, is defined as an excessive stretch or tear of muscle fibers and related tissues. Hamstring injuries are common in athletes participating in many sports. Track and field athletes are particularly at risk, as hamstring injuries have been estimated to make up 29% of all injuries in sprinters. Hamstring injuries can also come with a hip injury from sprinting. Symptoms for a hip injury are pain, aching and discomfort while running or any physical exercise. The biceps femoris long head is at the most risk for injury, possibly due to its reduced moment of knee and hip flexion as compared to the medial hamstrings. Causes of hamstring strain The muscle group is prone to injuries due to the explosive nature of movement in sports and thus causing overload and overstretching of the hamstring musculature. The other causes may be: * Previous injury * Poor muscle strength * Poor flexibility * Inadequate warm-up * Fatigue * Imbala ...

Muscle Strain
A strain is an acute or Chronic condition, chronic soft tissue injury that occurs to a muscle, tendon, or both. The equivalent injury to a ligament is a sprain. 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. Strains most commonly occur in the foot, leg, or back. Immediate treatment typically used to include four steps abbreviated as R.I.C.E. (rest, ice, compression, elevation) before the role of inflammation was found to be helpful. Signs and symptoms Typical Medical sign, signs and symptoms of a strain include pain, functional loss of the involved structure, muscle weakness, bruising, contusion, and localized inflammation. A strain can range from mild overstretching to severe tears, depending on the extent of injury. Cause A strain can occur as a result of improper body mechanics with any activity (e.g., contact sports, lifti ...

Hamstring
A hamstring () is any one of the three posterior thigh muscles in human anatomy between the hip and the knee: from medial to lateral, the semimembranosus, semitendinosus and biceps femoris. Etymology The word " ham" is derived from the Old English “ham” or “hom” meaning the hollow or bend of the knee, from a Germanic base where it meant "crooked". It gained the meaning of the leg of an animal around the 15th century. ''String'' refers to tendons, and thus the hamstrings' string-like tendons felt on either side of the back of the knee. Criteria The common criteria of any hamstring muscles are: # Muscles should originate from ischial tuberosity. # Muscles should be inserted over the knee joint, in the tibia or in the fibula. # Muscles will be innervated by the tibial branch of the sciatic nerve. # Muscle will participate in flexion of the knee joint and extension of the hip joint. Those muscles which fulfill all of the four criteria are called true hamstrings. ...

Muscle Fibers
Skeletal muscle (commonly referred to as muscle) is one of the three types of vertebrate muscle tissue, the others being cardiac muscle and smooth muscle. They are part of the somatic nervous system, voluntary muscular system and typically are attached by tendons to bones of a skeleton. The skeletal muscle cells are much longer than in the other types of muscle tissue, and are also known as ''muscle fibers''. The tissue of a skeletal muscle is striated muscle tissue, striated – having a striped appearance due to the arrangement of the sarcomeres. A skeletal muscle contains multiple muscle fascicle, fascicles – bundles of muscle fibers. Each individual fiber and each muscle is surrounded by a type of connective tissue layer of fascia. Muscle fibers are formed from the cell fusion, fusion of developmental myoblasts in a process known as myogenesis resulting in long multinucleated cells. In these cells, the cell nucleus, nuclei, termed ''myonuclei'', are located along the inside ...

Biceps Femoris
The biceps femoris () is a muscle of the thigh located to the posterior, or back. As its name implies, it consists of two heads; the long head is considered part of the hamstring muscle group, while the short head is sometimes excluded from this characterization, as it only causes knee flexion (but not hip extension) and is activated by a separate nerve (the peroneal, as opposed to the tibial branch of the sciatic nerve). Structure It has two heads of origin: *the ''long head'' arises from the lower and inner impression on the posterior part of the tuberosity of the ischium. This is a common tendon origin with the semitendinosus muscle, and from the lower part of the sacrotuberous ligament. *the ''short head'', arises from the lateral lip of the linea aspera, between the adductor magnus and vastus lateralis extending up almost as high as the insertion of the gluteus maximus, from the lateral prolongation of the linea aspera to within 5 cm. of the lateral condyle; and from ...

Pain
Pain is a distressing feeling often caused by intense or damaging Stimulus (physiology), stimuli. The International Association for the Study of Pain defines pain as "an unpleasant sense, sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage." Pain motivates organisms to withdraw from damaging situations, to protect a damaged body part while it heals, and to avoid similar experiences in the future. Congenital insensitivity to pain may result in reduced life expectancy. Most pain resolves once the noxious stimulus is removed and the body has healed, but it may persist despite removal of the stimulus and apparent healing of the body. Sometimes pain arises in the absence of any detectable stimulus, damage or disease. Pain is the most common reason for physician consultation in most developed countries. It is a major symptom in many medical conditions, and can interfere with a person's quality of life and general fun ...

RICE (medicine)
RICE is a mnemonic acronym for the four elements of a treatment regimen that was once recommended for soft tissue injuries: rest, ice, compression, and elevation. It was considered a first-aid treatment rather than a cure and aimed to control inflammation. It was thought that the reduction in pain and swelling that occurred as a result of decreased inflammation helped with healing. The protocol was often used to treat sprains, strains, cuts, bruises, and other similar injuries. Ice has been used for injuries since at least the 1960s, in a case where a 12-year-old boy needed to have a limb reattached. The limb was preserved before surgery by using ice. As news of the successful operation spread, the use of ice to treat acute injuries became common. The mnemonic was introduced by Dr. Gabe Mirkin in 1978. He withdrew his support of this regimen in 2014 after learning of the role of inflammation in the healing process. The implementation of RICE for soft tissue injuries as des ...
