Concentric: Movement where the agonist muscle (prime mover/s) shorten or contract. Any action where the muscular tension results in the shortening of the muscle causing a rotation around the involved joint.
In strength training or resistance exercise, the concentric action is the “lifting” part of the exercise. In the apparatus I performed, the part where I pressed against the weight to move it upwards by extending my legs was the concentric part of the exercise.
Eccentric: motion of an active muscle while it is lengthening under load
In a Leg/Knee Extension exercise, the action of lowering the leg back down from the lift is the eccentric phase of that exercise. This leg must be lowered slowly rather than letting it drop to allow the leg muscles
to be in a state of contraction and to control the rate of descent of the weight. Agonist: “Prime mover” muscle(s) that provides the major force to complete the movement. During the Leg/Knee Extension exercise, the agonist was the quadriceps (vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris) and soleus. These Antagonist: These muscle oppose the agonist. When the agonist contracts and causes the movement to occur, the antagonist is relaxed. The antagonist also helps slow down or stop a movement. The antagonist muscles of the quadriceps are the hamstrings (semitendinosus, semimembranosus, and biceps femoris (long and short head)) because when the leg extends, the hamstrings muscles are relaxed. However, when I lower my legs with a very heavy weight, the hamstrings help slow down or stop a movement by producing a sufficient amount of tension to help control the movement as the weight lowers.
The Blanket Exercise is a simulation of Aboriginal history from pre-European contact to the present. The Blanket Exercise was created in 1998 by Ed Bianchi, Suzanne Doerge, Chris Hiller, and Dr. Rose-Alma J. Mcdonald, from the Assembly of First Nations. A strong advantage of this resource is that it was created by a large group of Aboriginal peoples, including chiefs and members of major Aboriginal committees and organizations. According to their PDF document which can be purchased online, the goals of the Blanket Exercise include ensuring “that the living history between Indigenous peoples and newcomers is part of classroom learning”(Hill MacDonald, 2013, 4). The Exercise is “designed to help people understand how Indigenous peoples went from using and occupying all of the land [...], to a situation where reserves, [...] [amount] to only [...] 1%” of Canada (Hill MacDonald, 2013, 14). Throughout the Exercise, students gain an understanding of the many racist policies and practices that were imposed upon Aboriginal peoples and provides a critique of them. Critiquing these colonial practices is an important aspect of gaining a better understanding of the Aboriginal community, and this Exercise strives to teach students where the Aboriginal community came from and how they got to
Or if you have stairs at home, you can also do step ups to strengthen your lower leg muscles as well as your knees and hip joints. To do step ups, place your right foot on the stair platform and press on your right heel while you bring your left foot to the platform. Then return to your starting position with your right foot going down followed by your left foot. Then step onto the platform again using your left foot next. Do this 10 to 12 times on each leg for 3 sets.
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
A course in the sociology of sport and physical activity should be part of an undergraduate curriculum in a kinesiology program because social issues that impact sports and athletes are often overlooked within kinesiology program despite playing an important role within sports. Kinesiology programs tend to focus on the impact of sport and importance of sport and physical activity and could use the insight that sociology of sport and physical activity can provide. The more we know about the social issues around sport and physical activity, and how to limit them, the more we can understand sport and how to improve it and the equality within it.
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.
Throughout literature countermovement jumps (CMJ) are seen to be higher in contrast to squat jumps (SJ) (Bobbert et al. 1996; Kubo et al. 1999; Bobbert et al. 2005). However present literature regarding the key potential mechanisms behind why greater muscle forces are seen accelerating the body upwards in CMJ in comparison to SJ is somewhat unclear. A CMJ can be defined as a positioning starting upright, beginning the descending motion in advance of the upward motion in contrast to a SJ where the start position is squatted with no preparatory countermovement (Akl 2013). The higher jump heights seen in CMJ in comparison to SJ are apparent even if at the start of propulsion phase the body configuration is identical (Bobbert et al. 1996). In past literature three main mechanisms have looked to provide an explanation for the greater muscle forces seen in CMJ than the SJ. The first plausible theory is that the muscle stretch in CMJ increases the production of force capability of the contractile machinery (Edman et al. 1978; Ettema et al. 1992; Herzog et al. 2003). Secondly the assumption that the muscle fibres are on the descending limb of their force–length relationship at the start of propulsion in the CMJ and SJ, however in CMJ the stretching of a chain of elastic components, they are not as far past optimum length therefore allowing a greater force over the initial phase of their shortening range, with the stretching of sequences of elastic components, this then causes the storage of elastic energy that is then reutilized in the propulsion phase (Ettema et al. 1992). The final explan...
The knowledge of dance is important in the field of Kinesiology. Dance is a topic that Kinesiology majors should learn about because it helps them understand the fundamentals of the sub-disciplines in the major. Kinesiology emphasizes the study of human movement, such as physical activities, exercise, and health; therefore, it is a field that definitely encourages the knowledge of dance.
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.
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
Exercise is a structured sequence of movements performed consistently over a period time sufficient to build the components of fitness and improve
Walking on the street, jumping the fence, running the race, swimming in the pool or playing a football, if you keep on doing this, you are doing a wonderful job. Being a physically active not only improves your physical health, it also helps you built mentally strong. Physical activity encourages the brain to work at optimum capacity to increase productivity and helps to release the endorphins (the chemical produced by the brain) to make brain and body relaxed. The first step in life for prevention and management of disease and disorder is exercise. Exercise and Physical activity gain the attention of researchers regarding treatment of different psychopathological Disorder. Many research shows that involving in physical activity and exercise
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
Personal space, body language, and overall interaction between the participants in the gym was something that I hadn't paid enough attention to in the past, from the distance I could see that their interests. The intimate couples that I noticed in the gym seemed again sought to have created a private space for them by erecting invisible barriers through their private body language directed only at each other, resulting in considerable more space between these couples and other groups of people in the gym. It was a clear and present body language of please do not bother us attitude left a sense of diffused power that would be involved power relationships that operate without covert commands and requests. The dynamics of the couple was something that was very obvious, in that I was able to note the dominant and the submissive person. The person who had a tendency to meet the needs and the one who had the ability to be demanding.
Exercising is usually recreational physical activity carried out with the goal of building health and fitness. Looking forward to exercising and feeling really good with regard to the results of exercise on your body is common. Regular exercise improves mobility, overall flexibility, as well as balance in mature adults. Exercise also boosts the blood flow to the brain improving you mood.
Aerobics is defined as a system of endurance exercises that promote cardiovascular fitness by producing and sustaining an elevated heart rate for a prolonged period of time, thereby pumping an increased amount of oxygen-rich blood to the muscles being used. In the world today a large number of U.S. citizens are over weight, you see them every where from school, to work, you see over weight people. In our fast pace world right now many people don’t have time to work out and if they do then they don’t fell like exercising. We have cities where governors dare the people to lose weight, and the most popular New Year’s resolution is to lose weight. . In this paper I will explain the benefits of aerobic exercise and why everyone should do some sort of exercising.
