Introduction One of the most common injuries in sports of both genders is the tearing of the Anterior Cruciate Ligament, ACL. Each year there are over 200,000 reported cases of a torn ACL (Kim & Smith, 2009). Out of the 200,000 reported cases, an ACL reconstruction was performed in 175,000 of them with the majority of the procedures ending successfully, but failure rates averaged from three percent to high as 10% - 25% (Bogunovic, 2013). An ACL injury usually occurs while doing a move you have performed over a 100 times (Kidzworld). In other cases, a torn ACL is normally caused by getting hit extremely hard on the side of your knee, overextending the knee joint or by quickly stopping and changing direction while running (Kim & Smith, 2009). The ACL is the ligament that connects the tibia to the femur, and when it becomes torn it usually swells and produces a sharp pain immediately. Since the ACL is a pivotal aspect to a person’s knee, it is very important for scientists and doctors to figure out a sufficient way to heal it.
Normally when an ACL is diagnosed as torn, the first step of the healing process is to go through a couple weeks of rehab before surgery to help strengthen the quadriceps and hamstring muscle. The most common ACL procedure consists of taking a ligament from the patella tendon or the use of a hamstring graph. The use of the patellar tendon graft has been the “gold standard” choice for ACL repair since popularized in the mid-1980 with a success rate of 90-95% (Centers for Orthopaedics, 2008). Then once a surgery has been completed the recovery process typically lasts from six to eight months. During these long months of recovering is when the individual learns how successful…...

Dance Injuries and Prevention

...Dance Injuries and Prevention By Katrina Thompson Kin 380, Thomson April 20, 2011 Dance Injuries and Prevention Next to stage fright, the biggest nightmare for a dancer is to become injured. Injuries, depending on the severity, can mean the end of a career in dance and an end to something that you enjoy doing. According to a survey conducted on the injuries obtained by Broadway dancers, the most common injuries occurred on the lower extremities of the body at fifty two percent, followed by the back at twenty two percent, and the neck at twelve percent. The least frequent injuries occurred in the upper extremities with the shoulder consisting of only six percent of the dancers. Of the lower extremities the knee (29%), ankle (25%), foot (20%), and the hip (12%) were the more frequent sites of injury (Evans, Evans, Carvajal, Perry). In order to prevent these types of injuries from occurring it’s imperative that dancers follow the proper precautions such as stretching, proper warm-up techniques and general care for their bodies. After acquiring an injury you must follow proper treatments in order to recover effectively. Your spine is made up of three sections; the top portion or the cervical, the middle portion or the thoracic, and the lower portion or the lumbar (Anderson, Parr, and Hall). When it comes to back injuries, dancers tend to get injured in their thoracic or lumbar regions. The most common injury is frozen back. Frozen back is when the muscles in the back...

...this is considering that the goal was a few metres away from them, so that the kids didn’t find it to challenging. Since some of the kids didn’t know how to kick the ball properly. They struggled to perform to a good standard and this will result in the participant becoming feeling stresses and frustrated at themselves, therefore resulting in an unenjoyably, difficult session. But luckily, my friend employed a simple skill development session for some of the less technical kids in the activities, where there’s three people, one will throw the football to the Partners foot, so that he/she can volley the ball into the hoop (the third person will hold the hoop in the air), using their lace of the shoe to fully volley the ball into the hoop. After doing this each group of 3 will change places so everyone has a go. This will thus help in the improvement their sport skills and still acknowledge their sporting ability at the same time. My friend having the knowledge of people varying sports skills helped him excel in carrying out his session in an effective, successful format. He still has the knowledge to know who is right to play in matches, to maximise the chances of finishing in the top 4 in the Barclays premier league. He knows when to make the right decisions in a match situation whether to play a defensive or attack tactics or also knows who has the ability to play first team football and the other less technical players will play in......

Pay attention and be sure to consider the tips on the causes and prevention of sports injuries. Stretching and warming up is focal step in the attempt to prevent injuries. Growing up playing numerous of sports, I was always told to stretch before playing. Stretching before playing was emphasized by my coaches so I wouldn’t pull a muscle. Warming up is a four-step process. The steps include gentle loosening, some form of aerobic activity, static stretching and sport specific exercise (Bird). I always thought warming up was a one step thing. Meanwhile stretching and warming up does numerous of good things for the body to help prevent a nagging injury. Enhancing flow of blood to the muscles by increasing the heart rate, warming up muscles, tendons and ligaments are the main results for stretching before play. This is based upon the knowledge that cold muscles,......

...Sports Injury Assignment Moira Ijzerman Georgetown District High School Patellar Dislocation What is a Patellar Dislocation? The patella rests in a groove on the anterior aspect of the femur, called the patellofemoral groove (American Academy of Orthopedic Surgeons, 2011). Patellar dislocation occurs when the patella (kneecap) slides laterally out of the patella femoral groove where it normally rests (Ebraheim, 2011). Anatomy The patella bone protects the largest joint in the body, the knee (Temertzoglou & Challen, 2003). The knee is made through the union of 3 bones; the femur, tibia and the patella. (Physio Advisor, n.d.). The patella is situated at the anterior aspect of the knee and lies within the patellofemoral groove (Ebraheim, 2011) which, according to Physio Advisor (n.d.) is located on anterior of the femur. The patella is enveloped by the tendon of the quadriceps muscle, and then goes on to attach to the anterior surface of the tibia (Physio Advisor, n.d.). This relationship forms a joint designed to give the quadriceps muscle leverage when extending the knee (Sports Injury Clinic, n.d.). Each of the bones involved is lined with cartilage to allow cushioning between the bones. The patella also has connective tissue known as the patella retinaculum which attaches it on either side of the femur. This joint is known as the patellofemoral joint (Physio Advisor, n.d.). The patella normally lies in the patellofemoral grove and is only designed...

...Ashley Weiss Chapter 9 / 10 quiz 1. The thick filament which contain myosin are located in the H zone, M line and part of the A zone which is what is used for muscle contraction. The thin filaments consist of two strands of actin subunits twisted into a helix plus to types of regulatory proteins; troponin and tropomyosin. The sarcomere is the contractile unit, which is composed of myofilaments which also contain the A band, I band, H zone, Z disk and M line. Myofibrils are rod like contractile elements that occupy most if the muscle cell volume. Composed of saromeres arranged end to end they appear banded. The muscle fiber which is composed of many microfibrils is enclosed in endomysium and under that is the sarcolemma which houses the nuclei. Tendons connect muscles to their bony origins and insertions. Aponeuroses are layers of flat connective tissue (fascia) separating muscles from each other. The SR contain mitochondria and glycogen granules stored in the sarcoplasm which are involved in producing the energy for contraction. The fascicle is composed of many muscle fibers and is enclosed in the perimysium; the muscle is composed of many fascicles and is enclosed in the epimysium. The tubules of the sarcoplasmic reticulum have sac like terminal cisterns and the T tubules run between those. Spots that contain a t tubule and 2 terminal cisterns are called a triad. An action potential is carried down the sarcolemma to the neuromuscular junction . There are very......

Spinal Injury

...patient does not have a history of hypertension. Protonix: When spinal cord injury occurs above the level of T5, the primary GI problems that occur are related to hypo motility. Paralytic ileus and gastric distention develop as a result of decreased GI motility. Stress ulcers develop because of excessive release of hydrochloric acid in the stomach. Protonix is frequently used to prevent the occurrence of ulcers in the initial phase. 5. During an injury, the spinal column and the spinal cord can be injured anywhere along their length. The majority of the damage to the spinal cord occurs at the time of injury, but further damage can be caused by improper handling of the unstable spine and by the disruption of the blood supply, which can cause hypoxia and necrosis. Immediately following SCI, spinal shock occurs in the portion of the spinal cord that is injured and results in a complete loss of all motor, sensory, reflex, and autonomic function below the level of the injury. This loss is manifested in loss of bowel and bladder tone and peripheral vascular tone, which result in bladder distention, paralytic ileus, flaccid paralysis, and hypotension. After a period that varies from hours to months, but which usually lasts for 1 to 6 weeks, the spinal neurons gradually regain their excitability and the period of spinal shock ends. 6.

Skeletal Muscles

...1-Why do skeletal muscles enter in a contracted state called “rigor mortis” a few hours    after death and last for up to 72 hours? Skeletal muscle enter a contracted state called rigor mortis because the skeletal muscles are only able to partly contract. The muscles are not able to relax, so the joints are fixed in place. Rigor mortis can be used to help estimate the time of an individual’s death. The onset of rigor mortis may range from ten minutes to several hours. Maximum stiffness is reached around 12-24 hours after death. 2-You are watching a football game and suddenly, a player falls to the ground without any other player touching or tackling him? Explain what happens and why? A football player falls to the ground without any other player touching or tackling him because he had a muscle cramp. Muscle cramps can happen without muscle injury. They are involuntarily and forcibly contracted muscle that does not relax. Muscle cramps can be due to poor blood cicculation in the legs, overexertion of the calf muscles while exercising, insufficient stretching before exercising, muscle fatigue, dehydration, or magnesium and potassium deficiency. 3-Every year in March, the LA Marathon gathers a big crowd and lots of participants.    In the middle of the run, you notice that some players fall to the ground, although they    Had a good start and seemed to be the favorites.

Case Study: Rotator Cuff Injury

...Rotator Cuff Repair PATHOPHYSIOLOGY Wells K (2013) defined rotator cuff injury as a condition involving damage to the rotator cuff tendons because of continuous irritation and tear. There are two factors that can predispose a person to this type of injury. The first type is intrinsic factor which means coming from within, this includes poor blood supply to an organ, normal attrition or degeneration with ageing and calcification of tendons. The other factor is called extrinsic factor which means coming from the outside. Some of the factors considered extrinsic are injury from accidents, falls and too much stress on the shoulders as a result of different movements involving exertion (Bilal, 2013). The injury is frequently associated with athletes who move their arms above the head in a repetitive manner like pitching, swimming, tennis and weight lifting (Wells, 2013). Paul’s occupation which is carpentry work and the repeated pitching and lifting of the ball during the rugby game eventually contributed to the irritation of his tendons from excessive pressure on the acromion process or bony knob of the shoulder. This also resulted to the swelling of bursa which is the lubricating sac between the tendons and the bones from subsequent rubbing against the acromion. Consequently, the shoulder becomes painful and if left untreated can lead to a tear in the rotator cuff and eventual injury to the shoulders (NMA News Direct, 2011). Predisposing Factors: Carpentry (repetitive...

Injury Report

...Running head: Meniscus Tears Meniscus Tears Kaitlyn Hutchins Liberty University Meniscus Tears Description of Injury The meniscus is separated into two separate menisci. A medial, more crescent shaped menisci, and a lateral, more circular one. The meniscus is responsible for lubricating and nourishing the knee joint and assisting with joint biomechanics by mainly providing shock absorption during weight bearing. Injuries to a healthy meniscus are usually produced by a compressive force coupled with transverse-plane tibiofemoral rotation as the knee moves from flexion to extension during rapid cutting or pivoting (Brindle, 2001, 160). Meniscus tears can be considered acute or chronic depending on the mechanism of injury and the participants injury history. The patient may even be able to continue participation in activities but will notice a significant loss of the range of motion in the knee joint and a feeling that the knee is “giving out”. In many cases, it is the medial meniscus that is more commonly injured due to the fact that it is much less stable because of its crescent shape, and because it is also attached to the medial collateral ligament. Mechanisms of Injury The possible mechanisms of injury for meniscus tears varies from rapid cutting or changing of directions while running, to extreme compressive force to the lower leg region causing unnatural stress on the menisci. There are three different types of tears to the menisci which include a “bucket......

Life After a Spinal Cord Injury

...Running Head: LIFE AFTER A SPINAL CORD INJURY The Quality of Life After a Spinal Cord Injury Jennifer Brenner Florida A&M University School of Nursing Hocevar and Gray (2008) states , “Spinal Cord Injury (SCI) is a devastating and life-altering event, either temporary or permanent that affects motor and sensory integrity resulting in paralysis of lower or both upper and lower extremities, as well as autonomic nervous system function resulting in neurogenic bowel, neurogenic bladder, and sexual dysfunction” (p. 160). The majority of spinal cord injuries occur in young individuals and there is no treatment option for restoring spinal cord function below the level of injury. Approximately 253,000 people in the United States are living with SCI, and an estimated 11,000 new injuries occur each year (Hocevar & Gray, 2008). However, the complications of SCI can be reduced by medical treatment and rehabilitation. The purpose of this paper is to review research articles addressing the impact of SCI on quality of life from alterations in physical, cognitive, and emotional function. Studies have been conducted and showed that chronic pain and neurogenic bowel functioning are some of the major sequelae of SCI and they have a considerable impact on quality of life Living with a SCI is overwhelming due to the adjustments in lifestyle: the environmental barriers and activity limitations.
