Football and track and field involve repetitive bouts of quick acceleration for short and long periods, sudden changes in direction of maximum force may contribute to the high rate of hamstring strain commonly found amongst these sports. (Ropiak & Bosco, 2012). Regardless of all the aforementioned studies, there is not one exact cause of injury during high speed, kicking sports (Lees, Asai, Andersen, Nunome, & Sterzing,

Common lower extremity injuries for runners are iliotibial band syndrome, patellofemoral syndrome, patellar tendonitis, and plantar fasciitis. Iliotibial band syndrome occurs in runners who perform long distance training because of excessively bending and extending their knee (Grau, Maiwald, Krauss, Axmann, & Horstmann 2008). This will cause the distal iliotibial band to rub or brush against the lateral femoral condyle which will cause inflammation and swelling of the iliotibial band (Grau, et al., 2008). Patellofemoral pain syndrome or “runner’s knee” can cause excruciating anterior knee pain because of weak hip abductors, quadriceps, and external rotators (Petersen, Ellermann, Gösele-koppenburg, Best, Rembitzki, Brüggemann & Liebau, 2014). This will wear down, disrupt and ultimately damage the cartilage under the knee cap. Patellofemoral pain syndrome will cause imbalance and instability of the patella, hamstring

The ankle joint is the most commonly injured part of the body for individuals who participate in competitive activities, accounting for approximately 30% of all sports related injuries (Boyas, Hajj, & Bilodeau, 2013; Hootman, Dick, & Agel, 2007; Waterman, Owens, Davey, Zacchilli, & Belmont, 2010). It was estimated that in the United States alone, there are around 25,000 ankle sprains suffered each day(Olmsted, Vela, Denegar, & Hertel, 2004). A systematic review has analyzed articles published between 1977 and 2005 in 70 sports, and demonstrated that the ankle was the

The most common ligamentous injury to the knee is injury to the anterior cruciate ligament (ACL) (Teske 2010), and it is the second most common injury in the lower extremity. It has become so common of an injury that 1 in 3000 individuals in the United States will be affected with an ACL tear (Micheo 2010) and there are 200,000 new cases per year (Wilk 2012). It is most commonly seen in people 15-30 years of age (Teske 2010). It is also more common in females than males (Fayad 2003, Teske 2010, Bowerman 2006). This is due to increased joint laxity in post-pubescent females compared to post-pubescent males (Bowerman 2006) and differences in muscle activation. Males tend to have a more balanced quadriceps to hamstrings ratio

Our study proposes to examine the effects of a training program on high school female soccer athletes in regards to their risk for an anterior cruciate ligament (ACL) tear using surrogate markers. A randomized control trial will be employed on eligible female soccer athletes that are age fourteen to eighteen taken from two different schools. We will be using a convenience sample with one school being the control group and the other being the experimental group having a total of 56 participants after accounting for attrition. A seven question screener survey was created for this experiment to help screen out possible confounders. Data will be gathered by careful measuring of the exercises performed. More specifically, weight increase, range of motion increase, and repetitions performed. A proportion test will be used to analyze the data. The purpose of this study is to determine if, at the high school level, a specialized exercise program will help decrease the chance of ACL tears through strengthening the hamstrings.

This scientific review is about women in professional sports knee injuries vs men’s knee injuries. Many scientists have researched this topic and have found data that correlates with other

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

Anterior cruciate ligament (ACL) injury is a common sports injury occurs widely in the USA with the majority of suffering by healthy individuals with 70% of non contact period, during a variety of movements such as jump landing, cutting and pivoting (21). Different risk factors should be considered for injury, such as environmental, hormonal and biomechanical (18, 19). ACL injury prevalence is very high in soccer as well as other sports in females compared with males (29). Anterior shear force, valgus collapse, quadriceps to hamstring strength ratio (1, 21, 35, 37) are considered as other main risk factors in both genders. Co-contraction of the hamstring and quadriceps has been shown to provide dynamic stability to the frontal plane at the knee that protects maximum knee abduction loading (35). So, the main focus of the study should be on muscular strength between agonist –antagonist muscle of lower limbs and recovery after injury. Female athletes get injured almost 2-8 time higher than the male counterparts (1,5,7,19,21,24,29,33,35). Interesting point for comparing injuries in sports, dominancy of leg plays a role in ACL injury. In a non contact injury, females are more prone to get injured in their supporting leg, whereas male soccer athletes tend to injure the ACL in their preferred kicking leg (5). Biomechanical point of view, such as more extended hip-knee landing technique postures, knee pressure

Majority of sports injuries are muscular strains of the lower limb. These injuries make up a third of all sports referrals to sports physicians and their frequency and disabling effect is well documented according to recent literature. The most common muscular strains of the lower limb are hamstring strains which accounts for 12-16% of all injuries in athletes with a re-injury rate of 22-34% in a much recent research. Although systematic epidemiological studies within athletics are scarce, testimonies from coaches and athletes are consentient, pointing to a high frequency of hamstring injuries, especially in sprinting. Throughout the last several decades, several serious attempts have been made to understand the cause of hamstring muscle strain

This study was a randomized control trial in patients of 18 to 35 years of age, who presented to an emergency department with recent rational knee trauma to a previously uninjured knee within the last four weeks. Anterior cruciate ligament insufficiency was determined by clinical exam, and a score of five to nine on a tenner activity scale before the injury. 5 indicating participation in recreational sports and nine representing competitive sports. Possible participants were excluded if they had a full thickness rupture seen on magnetic resonance imaging, or if they have had a previous knee injury. (Frobell, Roos, Roos, Ranstan, & Lohmander, 2010)

Osteoarthritis is associated with the aging process, obesity, and a sedentary lifestyle, however, it affects athletes and adults as young as 25. Detection is difficult because of increased pain thresholds and oblivion or denial of the symptoms (Amoako, A., Pujalte, G.G., 2015). The diagnostic process is involved, requiring physical examination, radiologic examination, and laboratory evaluations. Treatment is based around symptom relief, often leading to invasive surgical procedures.The science behind diagnostics is evolving, with new prospects on the horizon, including biological markers and the use of ultrasonography.

There is a wide range of “runners” – those who run for exercise, run for competition, or run for their entertainment. Runners are always searching for ways to stay uninjured, either stretching more prior to their run, wearing comfortable and supportive shoes, etc. Physical therapists are not fully able to help injured runners unless they understand what “running” is. An injury is never simple; there are several factors to a runner’s injuries. They include, the athlete’s diet, sleeping habits, goals, and “training errors” – running too fast, too long, or too often. Training habits are usually 70% the reason why runners injure themselves. Physical therapists wish there was one “correct” way to run, but there is not. The only thing therapists

Demands placed upon the body during moderate-to-vigorous exercise as seen with running seem to produce endless health benefits. However, vertical forces on joints may be excessively demanding and could cause cartilage injury, leading to OA.3 Thirty million individuals participate in marathons each year with older women being the majority of new participants. Previous studies have looked at the effects of marathon running on knee joints by use of MRI. Studies have shown no significant MRI changes before or after marathon runners but do suggest that previous injury may elicit degenerative
