A hamstring strain, also known as a pulled hamstring is an excessive stretch or tear of muscle fibers and related tissues. These injuries are extremely hard to rehabilitate and treat. A pulled hamstring is classified by grades 1, 2, 3 depending on how bad the injury is. The hamstring muscle group is made up of three separate muscles; biceps femoris the semitendinosus, and semimembranosus. Hamstring strains that are sprinting related most likely will occur lower down the thigh in the long head of the biceps femoris muscle.
The way the injury begins is the sudden jerking of the tissue of the tissues in the hamstring muscle. If there is a pop heard then that means it’s the beginning of the injury. A variable amount of pain is experienced immediately.
The athlete is usually unable to continue and oftentimes can’t even stand. Examination of the individual with a hamstring injury reveals tightness, tenderness, and spasms. With more severe injury, swelling and a black and blue or bruised appearance will follow. Strains and tears most often occur at the middle of the back of the thigh where the muscle joins at the origin of the hamstring or tendon at the base of the buttocks. In some cases, a palpable defect (which can be detected by touching) will be in the muscle. The proper way to treat the injury is to rest the leg and avoid putting weight on it as much as possible. If crutches are required then the injured athlete must go to their doctor and request them. The athlete is then supposed to ice it to reduce pain and swelling and it should be done for 20-30 minutes every three to four hours for two to three days. After that, the leg should be compressed and the athlete should use an elastic bandage around the leg to keep down swelling. The leg should then be elevated on a pillow when they're lying or sitting down. You can tell the injury is improving when you can move your leg as freely as your uninjured leg. Your leg should feel as strong as your uninjured leg. You should also feel no pain in your leg when you walk, jog, sprint, jump, or do any leg workouts. You should be able to return to your sport or workouts with any kind of problem in your leg. Ways to prevent a hamstring injury is to stretch before and after physical activity. Always increase the intensity of your physical activity slowly -- no more than a 10% increase a week. Stop exercising if you feel pain in the back of your thigh. Stretch and strengthen hamstrings as a preventative measure. Appropriate fluid intake and a well-balanced diet is a way to avoid an injury, as well as dehydration and imbalance. Dehydration can lead to cramps, which will raise the chance of an injury. The risk of muscle injuries in the lower extremities can be increased by excessive body weight.
Sometimes the UCL will weaken and stretch (technically a sprain), making it incompetent. Other times a catastrophic stress will cause the structure to "pop" or blow out. The injury isn't tremendously painful, and it can be incredibly diffic...

A rotator cuff is simply a group of four tendons and muscles that are located right on the shoulder and on top of the humerus bone. (Source 1) The rotator cuff is what controls the shoulder and allows it to move and be mobile. The four main muscles that consist of the tendons are the supraspinatus, infraspinatus, teres minor, and subscapularis muscles. (Source 2). Too much wear and tear on these muscles (such as too many thrown fastballs) is precisely what causes the rotator cuff to begin to tear, as well as swelling in the tendons.
One major injury suffered in the shoulder is to the rotator cuff. The rotator cuff is a group of muscles and its surrounding tendon in the shoulder. These muscles and tendons (rotator cuff) serve to stabilize the shoulder. Many athletes are at risk of injuring the rotator cuff through repetitive impact and sudden movements.
Signs: These types of injuries can sometimes be hard to spot. Lameness ranges from barely at all to severe, depending on how bad the damage is. If the tear is in the main part of the ligament or the branches, the leg may become warm or swollen and sensitive at the site. If the tear is higher up the ligament, it
Hamstring injuries are one of the most common injuries in sports. They are especially common in sports that require a high degree of power and speed such as soccer and Gaelic football. (Sports Medicine Australia).
Snap, crackle, pop. That is the horrific sound a baseball pitcher hears after throwing a pitch. The UCL tear used to haunt pitchers forever until 1974, when a man named Tommy John had surgery to repair his UCL tendon and it was successful, causing this surgery to transform baseball. Before his arrival, Tommy John Surgery was known as a “dead arm” injury (Tommy John Surgery). When doctors diagnose players with this injury, it’s no longer a total shock as today you are easily able to come back from this surgery as when 30 years ago, you couldn’t.
Muscle endurance is the ability to perform a lot of repetitions against a given resistance for a long period of time. The combination of strength and endurance results in muscle endurance. Muscle endurance is used in may sports such as rowing, swimming, cycling, distance running, field hockey and American football. Normally, an endurance muscle program involves lifting about 12-25 repetitions of moderate loads. In some cases, this is inadequate for many sports such as boxing, canoeing and x-cross skiing.
Kinesiology can be defined as the study of mechanics of body movements, so I think that is very important to know the meaning of movement when studying kinesiology. Everything in kinesiology has to do with the movement. Every action the body takes is a movement which is what kinesiology is. You cannot be successful in the field of kinesiology no matter what you are doing if you do not understand what movement is. It is the study of human movement, performance, and function by applying the sciences of biomechanics, anatomy, physiology, and neuroscience. It looks at movement and which muscles are involved to create movement relating to strength exercising and sports technique. Movement is an act of changing physical location or position or of
The most common way to tear the A.C.L is by violently twisting the knee. This can happen with or without contact. Most people say they hear “a pop“. It can occur when you‘re slowing down from running, planting and suddenly changing direction, or hyperextending the knee. “When this happens immediate pain results, the knee will fully swell, tenderness occurs around the knee, and the range of motion will be greatly affected.” ( Micheli, Dr. Lyle J. ) The first thing to do if an injury occurs is to use R.I.C.E., which stands for rest, ice, compression, and elevation.
There are many injuries in general, but sports injuries? Sprains and Strains are the most common injuries in sports. “Sprains are injuries to ligaments, the tough bands connecting in a joint. Suddenly stretching ligaments past their limits deforms or tears them” (Hoffman 1). Ligaments are like springs in a sense that when you stretch a spring, it will return to it’s normal state unless they are
With all of the tears, the first type of tear is one where the labrum is torn all of the way off of the bone. This type of tear usually correlates with an injury to the shoulder where the shoulder has subluxated or dislocated. Sometimes, this tear occurs and the individual does not realize that the shoulder has slid out of the socket. This can make it much worse and cause other types of injuries to the ligaments around the shoulder.

Rotator cuff tear – The muscles adjoining the shoulder joint are required for rotating the shoulder, amid other movements. The tendons of these muscles furthermore influence the structural strength of the shoulder joint. Harsh, rapid actions, for example in tennis and baseball, can result in tearing of one of these tendons. This then causes pain as well as a decline in range of motion. Surgery possibly will be necessary to repair a torn
Muscle soreness can be experienced in different degrees. The first degree of soreness can be described as acute muscle soreness. It is mostly experienced after long hours of exercise and can last up to 3 days with new athletes. It majorly results due to exercise thus muscle fibers are subjected to micro trauma and excess accumulation of lactic acid. This soreness shows muscle growth and adaptation to trauma. This soreness is overcome by continuous training until the body adapts to the training program.
