According to the Dictionary of Sport Science, 1992 technique is best defined as “a specific sequence of movements or parts of movement in solving movement tasks in sports situations”. Bober, 1981 suggested that using kinematic and temporal variables is the best way to illustrate technique. Most reports reviewing technique reported the use temporal occurrence of linear and angular displacements and velocity and their amplitude. Other implements are available for quantifying biomechanical movement such as electromyography, plantar pressure and kinetic analysis. Technique is not always a positive indicator of performance as good technique is not always an indicator of good performance, there can be other influences although generally good technique can improve performance (Lees, 1992).
Technique analysis’ are useful in aiding coaches improve athletes performance by linking their performance skills with biomechanical principles. One form of technique analysis is quantitative analysis. The advantage of quantitative analysis based on scientific principles is that it can be applied to various settings such as instructional and clinical (Lees, 2002). The purpose of this research is to assess the advantages and disadvantages of wearing different foot wear or wearing no footwear on running performance. As well as this, the research will examine what advantages are gained by wearing the Vibram Five Finger shoes in comparison to running barefoot and with ordinary running trainers. Ten healthy male participants will be recruited to examine the differences between conditions. The three main components of ground reaction forces will be measured using a Kistler force platform. Spatio-temporal and kinematic variables will be calculated by videot...

...gers mimicked barefoot running as well as adding a thin layer of protection to the foot. A higher pressure under the metatarsal head and a higher thrust peak force suggests that runners can push off more vigorously when wearing the Vibram Fivefingers compared to barefoot. The sample size of this study was however only eight subjects therefore too small to draw any definite conclusions. They calculated only sagittal data thus modification in the transverse and frontal plane could not be examined and is it possible that accuracy was limited in calculating angular values at foot strike as a 60 Hz frame rate was used. Plantar pressure of the shod conditions could also be helpful in gaining a more conclusive outcome. Overall, Squadrone and Gallozzi found similar results to the claims made by Vibram however there were limitations and further research is still required.

While over the spring break my father, boyfriend, and I partook in supporting our home towns local ice hockey team the San Antonio Rampage take on Grand Rapids Griffins. However, while going through the procedure of finding our seats, attaining snacks and beverages, and watching the game I was able to examine different kinesiology components throughout the event. Just by entering the AT&T center one can be overwhelmed by the lights and excitement of everything going on however, the organization going on here is very extensive and if broken down they can analyze how everything can relate to sports kinesiology in some way.
Biomechanics allows the study of ice hockey to occur. In terms of ice hockey, biomechanics can be used to study a players shot, a goaltenders movement, line changes where players jump over the boards to get on and off the ice, and impacts. Multiple options are available in regards to recording biomechanical values during ice hockey play. These options often include instruments with the player’s helmet, which do not disrupt the player’s movement. Other options being used are accelerometers attached to the players extremities. Currently studies in ice hockey are looking at head impacts and the injuries connected to those impacts. These impacts are often categorized between event type, impact location, and impact object. These categories are helpful in determining what happened to cause the impact, once the impact is determined biomechanics is used to determine liner and rotational accelerations. The values that are calculated for the linear and rotational accelerations can be used to determine if head injury is likely for similar events or if a head injury occurred during the event
Past studies have showed mixed evidence regarding the effects of load carriage on stride length. Some studies have observed a decrease while others noticed no change in average stride length. Past studies have also been inconsistent with the usage of hip straps that are meant to transfer weight onto the larger muscles groups of the legs, which might lower metabolic cost. Our experiment considers both flat and inclined surfaces when determining whether backpack loads and the usage of hip and chest straps affect a walker's step length and post-exercise heartrate. The degree of increase of the post-exercise heartrate from the resting heartrate was used as a measure for fatigue in the subjects. Sixteen college students underwent eight walking trials on a treadmill on which the speed and distance traveled was fixed. Our data indicates that load carriage decreases average step length when the walker is on an inclined surface, but not on a flat surface. In addition, we found that load carrying, regardless of whether hip and chest straps are used, results in a greater increase in heartrate, both on a flat and inclined surface. Hip and chest straps used with loads are found to result in a lower increase in heartrate on flat surfaces, indicating a possible metabolic benefit of its usage.
Broer was the first to call attention to the similarity of movement patterns used in seemingly dissimilar activities such as the baseball pitch, the badminton clear, and the tennis serve. Objective evidence of such similarities between throwing and striking activities within each of the three major upper-extremity patterns; overarm, sidearm and underarm. The representative activities from these categories across throwing patterns also showed great similarity in the muscular action of the lower extremity. Atwater distinguished between the overarm and sidearm throwing patterns in terms of the direction in which the trunk laterally flexed. When lateral flexion occurred away from the throwing arm, and overarm pattern was used; lateral flexion toward the throwing arm indicated a sidearm pattern. The underarm patter is distinguished by motion predominantly in a sagittal plane with the hand below the waist. Each pattern involves a preparatory movement referred to as a backswing, or windup, followed by the establishment of a base of support prior to the initiation of the force phase and ending in the follow-through. The base of support in the direction of the force application; forward and backward is a distinguishing feature of skill level. It has been well documented that more highly skilled individuals have longer strides. Once the base has been established, the more proximal segments begin the force application phase while the more distal segments complete the backswing.

Using published peer review academic lecture, studies illustrate strength plays a significant role in basketball players as it’s a component they are very reliant on due to the power necessary for running, jumping, passing, shooting and rebounding. Many actions on the court are fast, that often involves a quick burst and necessitates great heights of power output, specifically in the leg and hip area as research has proven lower body strength increases an individual’s vertical jump (Baker, 2000; Fleck, 1999; Kevin & Fulton, 2001). Correspondingly the recruitment of muscle mass is crucial in basketball because this contributes to the stretch shortening cycle of the leg muscles that facilitates the leg muscles to create more contractile energy (Clutch et al, 2000; Bobbert and Van Ingen Schenau, 2002) as jumping plays a large role in an individual’s ability to jump for the ball. Therefore the purpose of this work-out preparation programme for Lewis Hards will dominantly be based upon strength as (many refs) reveal it’s a key catalyst in empowering athletes and enhancing human performance. Additionally it has been declared by (Chandler and Brown, 2008) it is important for the design of an appropriate training programme involves the controlling of the number of sets, intensity of exercise, volume, load, rate of progression and rest periods in order for greater gains in performance over the long term. In comparison it is also importa...

Creative new training methods, developed by coaches, athletes and sport scientists, are aimed to help improve the quality and quantity of athletic training ( Kellmann, 2010, p.1). However, these methods have encountered a consistent set of barriers including overtraining ( Kellmann, 2010, p.1). Due to these barriers, the need for physical and mental recovery in athletics brought an increasing attention in practice and in research ( Kellmann, 2010, p.1).

For me, I will focus more on the movement on the ankle and its placement to see if where the athlete is most comfortable. I find it important for the athletes to give me feedback on how they feel so that I can see how far I can push them to achieve their goal. The specific characteristics regarding this situation is to focus on the weight placed on the ankle at the time of the cut that they performed and the way the athlete pushes off their ankle. Since the athlete is trying to get back into the sport, they might have lost a bit of the motor skill or they might have increased their motor skill because they do not feel as comfortable putting a lot of weight and force on the ankle yet. As mentioned earlier, I will have them practice the three variations of the motor skill. With this, it can be known as practice variability, which is having different variations of skill in which the person experiences different contexts in which a skill can occur or different movement patterns (Magill & Anderson, 383). The athletes will practice the three variations every day, but I will definitely change up the order of the routine and make it random. They will also work on the variations but with different games and activities. With this, it will help with the retention of the skill and give the athletes
