The quadriceps is a group of four large muscles that sit on the anterior aspect of the thigh: Vastus Medialis, Intermedius, Lateralis and Rectus Femoris. Injuries to the quads are not uncommon for athletes in high-speed sports such as track or basketball (Brown, 2012), however, as common as these sprains are, they are treatable. According to Brown, a strained quad implicates a partial or complete tear of the one of the four muscles or their tendons when they're stretched beyond their normal limits. This muscle group is primarily used when kicking, jumping and running (Kary, 2010), which explains why it’s a common injury in sports such as soccer, track and basketball.
There are several ways that quads could be strained. There are cases were
the situation can predispose an athlete to this type of injury. Some examples of these predispositions include fatigued muscles, overused muscles, and muscles that did not get the proper warm-up (Brown, 2012). Another reason why this group of muscles is prone to strains is because they cross the hip and knee joints (AAOS, 2014). It is important that muscles receive the proper warm-up because if they are not warmed up they will be tight and susceptible to a strain or a tear. Poor conditioning is also a risk factor for this type of injury; muscles that are not strong enough to endure certain exercises are likelier to undergo an injury. Muscle fatigue is a common predisposition for athletes to suffer a quad strain. When muscles are tired their ability to absorb energy is reduced making them more vulnerable to injury (AAOS, 2014). . Excessive passive stretching or activation of a maximally stretched muscle can also cause strains (Kary, 2010) so it is important to know when the muscles are warm. This type of injury is also common an athlete is trying to gain speed (Brown, 2012) such as a spring race in track. An imbalance in antagonistic muscle strength, for example the hamstring being stronger than the quad, could also cause this injury (Brown, 2012). Lastly, there is trauma; a direct hit could cause a tear in the muscle leading to a more severe strain (Brown, 2012) as seen in football and other high-contact sports. Quadriceps tears and sprains can be identified by several characteristics. Tears can be described by a popping sensation where the muscle tear has occurred (AAOS, 2014). Some immediate pain always follows the strain, and the level of this pain depends on the severity of the tear. There are 3 grades of strains. J.M Kary describes the pain and strength loss of each distinct grade of sprain the following way: grade 1 is the least severe, characterized by a slight tear in the muscle with little or no strength loss. Pain is mild in this type of tear with no obvious deformities to the muscle when assessing the injury with touch. A Grade 2 strain is characterized by significant pain and loss of strength, and sometimes the tear could be felt when determining the severity of the injury. Grade 3 strains would be the most severe of the three, characterized by severe pain and complete loss of strength. The muscle tear could usually be felt in grade 3 strains. Bruising might be visible if there were any vessels broken where the tear happened and the muscle will be tender to touch (AAOS, 2014), this might be seen more commonly in grade 3 sprains.

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
Ligaments are tough, non-stretchable fibers that hold bones together. Damage to cruciate ligaments, which crisscross the knee to give it stability, is one of the most common sports injuries. The “tear” occurs from changing direction rapidly, slowing down from running, or landing from a jump improperly. The A.C.L tear is one injury that worries athletes in all sports at all levels because of its devastating effects. People ages 15-25 that participate in basketball and other sports that require pivoting are especially at risk.

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
Physical therapy and kinesiology work in a close relationship to each other. Essentially one may think they are one in the same, however there are small differences between the two that provide different results when applied singularly. As a combined effort physical therapy and kinesiology work to heal the muscles and joints of the body, recreating movements perfectly as they were before injury or in some cases as closely as one can get to a perfect function. First one must understand where the lone is drawn between the two fields and how they balance each other to create desirable results in a patient.
...tead of one big one. Building your leg muscles, especially your hamstrings can help prevent ACL injury. Be thoroughly warmed up before jumping and pivoting hard. It is a good idea to be actually sweating when you are warming up.
Evidence of lifting weights can be traced back to the origins of man. As far back as cave painting and scrolls, there exists evidence of weightlifting. Initially as an expression of strength, to competition and functional training, weightlifting has carved its path through the ages. It has taken on a new role in the modern world; athletic training. With an entirely new emphasis in sports on speed, strength, and flexibility; weightlifting is more popular than ever. Unfortunately, young athletes often do more harm than good by injuring themselves lifting. When these uneducated lifters try to jump right into a program, lifting more than they should, an injury is imminent. What is overlooked, is that when weightlifting is done correctly, it has a great potential to prevent injuries instead of cause them. Understanding how the body works, using proper technique on the appropriate lifts, and participating in regular physical activity can greatly reduce the risk of athletic injuries.
The knee joint is extended when in the standing position, to stabilize this joint the biceps femoris, semi-mebranosus, semi-tendonosus (hamstrings) and the rectus femoris, vastus lateralis, vastus intermedius and vastus medialis (quadriceps) co-contract isometrically.
What is Biomechanics? It is the study of forces and their effects on the living system (McGinnis, 2013). In this essay, I will be looking at the biomechanics of running. Running, as well as any other sport requires skills for which advancement is due to consistent deliberate practice and effective development. However, runners should establish a training system that actively builds their original running pattern instead of basing it on what works well for others. Understanding the biomechanics of running gives a better knowledge of their running techniques and points out areas of concerns that require improvement. Despite the fact that running is dependent on the interaction of the whole body, breaking down the running pace into single components allows us to further understand how minor changes can increase improve performance and decrease injury risk.
The purpose of the squat is to train the muscles around the knees and hip joints, as well as to develop strength in the lower back, for execution of basic skills required in many sporting events and activities of daily living. Because a strong and stable knee is extremely important to an athlete or patient’s success, an understanding of knee biomechanics while performing the squat is helpful to therapists, trainers, and athletes alike (11). Because most activities of daily living require the coordinated contraction of several muscle groups at once, and squatting (a multi-joint movement) is one of the few strength training exercises that is able to effectively recruit multiple muscle groups in a single movement, squats are considered one of the most functional and efficient weight-bearing exercises whether an individual’s goals are sport specific or are for an increased quality of life
My understanding of kinesiology prior to enrolling in the course, is that I knew kinesiology is the scientific study of human movement , and that it involved sports and exercise and physical activity.I 'm interested in kinesiology , because I love anything that has to do with sports, and to get more of a detailed report on how human movement plays such a big role in the sports world.I have played sports for most of my life my interests our football, basketball,baseball.I started football my eighth grade year, and continued to play threw high school, until I tore my meniscus and mcl so I skipped my junior year of football , and came back my senior year had a really great season started at right offensive tackle.Missing my junior year in football really took a toll on me ,I could have gained so much more experience playing if so. I 've played basketball probably since the third grade , and continued to play threw high school even threw my knee injury ,I played travel basketball as well a
Agreeing with the fact that Kinesiology is a “invisible” field. I was not aware of this field until I came to UNI and was looking at different majors. I looked into this major and found it interesting as well as unique. What got me interested in this major was the very fact that Kinesiology has no common name or identity. Upon graduation I have doors open to make other fields. Not having a proper or universal recognition can be beneficial, in a way where we can attach and fit into different departments. Being invisible gives us the opportunity to collaborate with other departments and opens endless doors towards to multiple occupations and work of study.
Prosthetic limbs have been in use for thousands of years and have become more and more technologically advanced. Historically, prosthetic limbs have been awkward, uncomfortable, and merely a means of alleviating some of the problems that came with the loss of an arm or a leg (Bidlack), but as science behind prosthetic limbs advances, as do their capabilities to perform like normal limbs would and perform tasks previously unachievable by amputees. With technological advancements, questions arise regarding whether or not prosthetic limbs are actually better and more efficient than our own human bodies. As concerns grow, so does the controversy surrounding the participation of amputee athletes in professional sports sanctioned for able-bodied
Athletics were one of the most significant aspect of ancient Roman culture. The Romans hugely celebrated athletics and viewed as a form of an entertainment. The Romans were mainly attracted and played the athletics for glory, military preparation and entertainment. This essay can be substantiated through the following categories: origin of athletics in Rome, athletes, and athletics.
