The Reflection Of The Observation Of Vertical Jumping

“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).

All athletes regardless of age, gender, genetics or sport can benefit from effective training. It is important that the selected training improves the body’s ability to perform tasks associated with the chosen

There is a serious debate in the track and field community as to whether there is more benefit, namely increased distances, to be gained in the throwing events from improvements in technique versus improvements in strength. While this debate focuses primarily on the shot put and discus events, the events studied in this research, it is equally true for all the throwing events. As a significant part of the throwing community, the United States is thought of as a nation that focuses too much on strength, at the expense of technique.

Jumping (bilateral): Hip and knee is in extension, while ankle is in plantar flexion, and shoulder abduction and flexion while in the air.

This experiment was completed in order to compare calf circumference as well as weight to jump height. If a person has larger calves then they will likely be capable of reaching a higher vertical height. It can also be shown that since males tend to have larger calves, they can jump higher. A larger calf circumference is more likely to reflect a high vertical jump due to the fact that the fat content of the calves in the experiment was accounted for, therefore a large calf measurement in this experiment means a muscular calf. It is common knowledge that more muscle will result in stronger legs leading to a higher vertical.

The study of the human body and its movements has been present for centuries. While there has almost always been an interest in the human body and its way of working, modern technology and scientific discoveries have greatly aided modern medicine and research of human anatomy and physiology. These days, the study of medicine is far more extensive than many people understand, and those who want to pursue a medical field have great amounts of work awaiting. Athletic Training as a profession in this day and age involves extensive schooling, training, and focus when on the job.

In the story The Sports Gene, Thomas wanted to show he is good at long jumping but then he get a little ahead of himself and decides to go pro. David Epstein wrote, "Thomas decided to put his hops where his mouth was." Thomas wanted to prove to another athlete that he can do his challenge and show himself and others that he has a natural talent at long

Hamstring strain injuries are one of the most common sport related injuries involving high speed, kicking movements (Marc. A., et al 2004). Despite there being evidence that hamstring strains occur at both stages of movements; the early stance phase where the muscle absorbs the most force as a result of high ground reaction and the late swing phase, the hamstrings eccentrically contract to absorb the kinetic energy and slow the lower limb putting the hamstrings under a large amount of stress (Schmitt. B., et al 2012)

Content: overall development, focusing on ABCS (agility, balance, coordination, speed) to underpin the generic skills used in many sports (running, jumping and throwing).

(Hewett, 2005) Compared with male athletes, female athletes tend to generate greater abduction loads during cutting and landing, which may, in part, explain the discrepancy in injury rates observed between the sexes. (McLean S.G, 2005-2007) In regards to planes of motion, the quadriceps and hamstrings muscles have the potential to provide dynamic frontal-plane knee stability because of their abduction and/or adduction moment arms. (Lloyd D.G 2001) Exercising a neuromuscular biomechanical model, noted that the quadriceps and hamstrings not only have the potential to support frontal-plane moments but also actually do provide support to abduction-adduction moments (Lloyd D.G

As children’s bodies become more streamlined and less top-heavy, their center of gravity shifts downwards toward the trunk. As a result, balance improves greatly, paving the way for new motor skills involving large muscles of the body. (Berk, 1999) During the preschool years until approximately age seven, fundamental motor skills develop including the locomotor skills needed to run, jump, hop, and skip. Also the object control skills such as throwing, catching, and kicking are developing. By the age of six or seven, children begin to integrate two or more of these skills. Though all children will not develop these skills at the same age, they will follow the same sequence.

Motor skills involve movement of muscle in the body (John, 2009). These are larger movements such as crawling, running, and jumping (John, 2009). Most of the gross motor development occurs during childhood (John, 2009). Gross motor skills have two principals that determent how a child will regularly develop (Center of diseases Control and Prevention, 2016). Head to toe development this means the upper parts of the body will develop before the lower parts of the body (John, 2009). Children develop these skills throughout play (John, 2009). A tree year old Toddler can be very active therefore participating in activity that require movement, coordination, and balance can be beneficial to help a toddler to develop their motor skills (Jan, Beth & Melissa, 2012). A 3 year old child can throw a ball but catching it is more difficult. They start walking with good posture similar to an adult; they can also walk backwards (Jan, Beth & Melissa, 2012). A 3 year old can run which required strength and balance, during running they should be able to rotate their trunk and swing their arms (John, 2009). By the age of 3 a child walks up and down stairs alternating their feet without support which is possible because their balance has increase (John, 2009). A 3 year old child also learns to jump from a step and learn to jump forward (Center of diseases Control and Prevention, 2016). They start hopping at the age of 3 ½ and also can stand on one foot (Center of diseases Control and Prevention, 2016). Skipping requires sequencing and rhythm which makes it more difficult this include step and hop patterns.

The authors conducted this study to see how and when this ability in humans evolved by studying the mechanics used in throwing. They compared the mechanics of throwing of humans to that of chimpanzees. The authors said that previous studies found that the internal rotator muscles are responsible fort the power of the human throw. The investigators hypothesize that the elastic energy storage is the important source for this power. They also stated that other features of the human shoulder are important in storing this energy and
