Intrinsic Factor In Multidirectional Sports

“The analysis of movement provides an athlete with optimal development as well as minimising the risk of developing injuries through the incorrect execution of a movement” (Ackland, Elliott & Bloomfield, 2009, p 301).

Studies have also shown that women in particular, unfortunately have a disadvantage in life when compared to male counterparts, and that is one pertaining to their higher risk for ACL injury. Due to a neuromuscular imbalance that is concomitant with overactive quadriceps strength compared to hamstring strength, females tend to place more stress on the ACL. Accordingly, this increases the pressure on the ACL leading to a higher prevalence of injury that will arise more on the female spectrum than that of the male (Myer et al., 2009). Furthermore, this is important to be aware of for female athletes and for the Physical Therapists who treat them in efforts to provide educational information regarding the relationship of stronger hamstrings correlating to a lesser chance of ACL injury. Personally, I have worked with athletic females in the past as a personal trainer and while I was not strengthening hamstrings with the direct objective to prevent an ACL injury, I was cognizant of the notion that a balanced quadriceps and hamstring ratio was necessary to avoid lower extremity injuries as a

Lowering this rate would allow female athletes of all levels to have a lower probability of ACL injury. Sex difference has proven that female athletes are more likely to have an ACL injury than males. Since we are unable to change our sex (intrinsic factor), the focus must then be placed on the factors that can be modified. A list of these factors include: preparation, skill acquisition (from a young age), and playing style (Ireland, 1999). The factors listed are all controllable extrinsic factors, focusing on these and the partially controllable factors could aid in the prevention of ACL injuries in

In female basketball players, neuromuscular, hormonal, and anatomical factors were considered internal factors that were the cause of non-contact ACL tears. Muscle weakness in the gluteus maximus and hamstring muscles along with poor dynamic

With an ever increasing number of people becoming involved with athletic activities, there is an increasing number of injuries occurring which can be devastating for the individual. Most of the injuries that affect athletes occur in one of four structures in the human body: bones, muscles, tendons, or ligaments. Because ligaments attach bone to bone and play a major part in providing stability for joints, the major stabilizing ligament in the knee, the anterior cruciate ligament (ACL), assists in performing everyday actions of the human body including sitting, standing, walking, running, dancing, and participating in other sports. The injury that specifically affects this ligament is very serious and always

The Anterior Cruciate Ligament also known as the ACL is deemed the most commonly torn ligament in the knee and can result from both contact and noncontact injuries. Most Anterior Cruciate Ligament injuries result from an extreme force on the lateral side of the person’s knee causing a valgus force which pushes the knee inward (Kisner & Colby, 2012, pp. 802-803). This injury to the side of the knee can also cause a “Terrible Triad” injury which also injures both the medial meniscus and the medial collateral ligament (Kisner & Colby, 2012, p. 803). Our textbook further states that “the most common noncontact mechanism is a rotational mechanism in which the tibia is externally rotated on the planted foot….this mechanism can account for as many as 78% of all ACL injuries” (Kisner & Colby, 2012, p. 803). If the person does not seek medical help with this injury they are susceptible to also injuring the remaining support ligaments as well. Patients usually present with joint effusion; possibly 25 degrees of flexion, joint swelling if blood vessels are involved, limited ROM, stress pain and instability along with quads avoidance gait patterns (Kisner & Colby, 2011, p. 208)

Several recent studies demonstrate that the rate of ACL injuries among women can be significantly reduced by following proper neuromuscular training (NMT) and conditioning programs.

In her article, “High School ACL Injury Rates”, Dawn Comstock shows that in 2009, about sixty percent, of all sports surgeries involve the knee; within the sixty percent, about fifty percent of the knee surgeries are ACL reconstructions. Sports that could have a higher tendency for an athlete to tear the ACL are sports that require an athlete to decelerate quickly or need to cut and change direction instantly. For example, an article shows that a high-impact sport has a higher percentage of ACL tears when compared to a low-impact sport, such as football and women’s soccer; football has a forty-one percent ACL injury rate while women’s soccer only has nineteen percent. Not only does the level of impact effect the likelihood of ACL injury, but the gender of the athlete as well. When looking at women’s and men’s soccer, men have a merely thirteen percent ACL injury rate because their physical structure along with their techniques when doing certain exercises.

The Anterior Cruciate Ligament (ACL) is one of the most common knee injuries in female sports today. The ACL is a ligament that attaches the femur and tibia to the knee allowing the knee to bend while still being stable and supporting the whole body. Dr. Russel F. Warren, a physician for the New York Giants football team, explains, “The ACL prevents the shin bone (tibia) from moving too far forward on the thigh bone (femur) and keeps the knee from twisting inward excessively.” When athletes tear their ACL there is a greater chance that they have hurt or another ligament in their knee such as the LCL, MCL or Meniscus; which is cartilage that absorbs shock from the body’s pressure (MedlinePlus). The ACL is strong, but one wrong move could result

Female athletes can protect themselves through many stretches and prevention programs provided by their coaches, parents and Athletic Trainers. Many ACL tears can be protected by warm- up or cool-down programs or stretching (Ritter). The solution to preventing some of the ACL injuries is a strength and flexibility programs to strengthen the hamstrings, quadriceps and the core while stabilizing the knee (Busse). Working on the athlete’s techniques such as running, jumping and landing techniques can vastly improve their chances of ACL strength and would help prevent against tears (Malamut). Using an ACL prevention program teaches athletes how to align their hips for correct form and how to jump correctly without pain and without being knock-knee.

The Anterior Cruciate Ligament (ACL) of the knee is arguably one of the most notorious parts of the body in the sporting industry. When torn and repaired with surgery, it can leave an athlete out of play for up to 12 months if therapy is consistent over that time period1. There are several different ways to repair the ligament in order to regain functionality and recover stability. In any case, physical therapy plays a vital role in regaining these abilities and returning a person’s knee back to normal.

Anterior cruciate ligament (ACL) injuries are the most common of knee injuries especially occurring during sports related activity. These types of injuries may lead to short-term disability and as well as possible long-term complications. It is estimated that 80,000 to 100,000 ACL reconstructions are performed every year and a significant percentage of those surgeries are performed on female athletes. Female athletes experience ACL injuries about two or three times more often than men due to how the female body matures and her strength, or lack thereof. Because of the wear on a healthy ACL, the ACL might not last an entire athletic career especially in women. Some of the risk factors are unavoidable, such as hormone changes and gender, but the neuromuscular and biomechanical factors are controllable. If a female athlete can be properly strength trained and takes the necessary precautions, like stretching for flexibility and core training for muscle control and balance, she can greatly reduce the risk of injuring her ACL. If she does not take the necessary precautions and does tear her ACL, surgery is required to replace the torn ACL and rehabilitation of that ligament is necessary before returning to sports (Hewett et al., 2012; Siegel et al., 2012). Despite the advances in surgery, the long-term

Football is the most popular sport in the world.1 Playing football can improve musculoskeletal, metabolic, and cardiovascular functions.2 However, football is one of the sports that have the highest risk of ACL injury.3,4 The incidence rates of ACL injury in soccer range 0.15% - 3.67% per person per year and 0.07 - 1.08 per 1000 sports exposures across various age and competition levels.5,6 The majority of ACL injuries occur without external contact to the knee joint.4,8,15

When an anterior cruciate ligament (ACL) is torn/ruptured it can be considered one of the most agonizing experiences in an athlete’s career. It is thought to be one of the first things that pops into an athlete’s mind and for many even their greatest fear when they injure their knee on the field. A ruptured ACL can be so detrimental that it can possibly mean the end to an athlete’s career. It can signify for young athletes losing that chance of getting a scholarship as in this case and the end of their careers for those who have gone professional. A ruptured ACL can result in large amounts of pain, numerous surgeries and months of strenuous exercise and rehabilitation. It requires an athlete to be dedicated and patient as pushing too hard can result in further injury. This essay will discuss the pathology, the rehabilitation progress from six weeks to final stage including the athletes return to play after experiencing an ACL injury.

The majority of ACL injuries happen during athletic tasks with no external contact to the knee joint. This non-contact nature proves that these injuries are caused by abnormal movement which can possibly be changed through training. Understanding the pattern of movement for non-contact ACL injuries provides beneficial information for how to develop different strategies to train. A great effort has been made to identify risk factors for non-contact ACL injury by using different practices over the past 2 decades. An important strategy in particular used to identify movement characteristics during injuries is the analysis of video records of ACL injury cases. Cochrane et al analyzed video records of 34 ACL injury cases in Australian football (2007).
