Intro:
In this multimodal presentation, I will be discussing and evaluating certain factors of a skill used in volleyball, the dig. I will be discussing a muscular analysis of the dig I constructed earlier. I will be evaluating my performance and my strengths and weaknesses with respect to the biomechanical principles of force, internal and external and motion. I will also be discussing and making recommendations on how I can improve all the identified weaknesses I currently possess.
The dig in Volleyball sets the ball so team mates can set the ball so another team mate can spike the ball to win a point. Joints that move from these muscles are the ankle, knee, hip, trunk, shoulder, elbow and wrist.
The following paragraph is a muscular analysis

• The subscapular is located at the underside of the shoulder blade causes rotation of the shoulder.
• The anconeus located at the central side of the ulna to the lateral side of the humerus causes full lock of the elbow.
• The Extensor Pollicis Brevis located at the radius to insert on the thumb causes the thumb to straighten out with the arm.
Strengths and weaknesses:

Simultaneous Summation of force is where many muscles are used at the same time to maximise force with any movement and Sequential Summation of force involves a number of different body parts contributing in a sequence to generate force, this summation of force is usually used when striking a golf ball, kicking a ball, pitching a ball, etc. The heaviest and slowest body parts/muscles move first, the smaller and faster body parts/muscles move last maximising force. The dig in volleyball uses simultaneous summation of force, as I am pushing up from my legs and extending my elbows to gain force to dig the ball. The summation of force works as a strength when digging the volleyball, as it maximises force allowing more control and height of the ball setting the ball for teammates to set or spike the ball with
In lacrosse, the overhead shot is the most vital part of the game and the most important skill that an offensive player can have. The goal of the lacrosse shot is to create a scoring attempt with peak speed and accuracy. Each player is different regarding personal technique; however, the basis of each shot remains the same and are interpreted through six phases. The general purpose of this paper is to describe trunk rotation and its impact on power and accuracy which will maximize the potential of a lacrosse shot.
In the frontal plane, the movement shows the depression of scapula. The joint involved in this part of the pirouette is the scapulothoracic joint. This motion can be analyzed in the frontal plane or the sagittal due to the movements of the shoulders with the trunk (Hall, 2011). In the transverse plane it is the external rotation of the hip that helps form a pirouette. The muscles used to perform the rotation are the gluteus minimus, piriformis, superior gemellus, inferior gemellus, obturator internus, obturator externus, and quadratus femoris (Hall, 2011). These muscles are used to help the leg move to the correct position for a pirouette.
The origin of the triceps brachii is also from the scapula like the biceps brachii. In a mink, the extensor digitorium originates on the lateral epicondyle of the humerus yet in humans it is present in the posterior forearm and is responsible for extending the phalanges, wrist, and elbow in both species. Anothier muscle with similar functions to the extensor digitorium is the flexor carpi ulnaris but instead it is soley responsible for flexin... ... middle of paper ... ...
Talus (Ankles): To start and stop quickly. Tibia, Patella (Knee): To bend over to hit the lower shots. Muscles used in tennis serve When serving a tennis ball, all the muscles of the body are involved, since you are throwing a ball up, taking a step back and then swinging your arm forward to hit a ball using the whole of your body for follow-through.
Also, it was stated that because of the elbow angle at foot stride and ball release that the shoulder joint was affected more so than at any other time. Finally, in order to understand why the injuries occur we should learn the joint ranges of motion so we can develop better preventive methods for injuries.
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
The surfaces of the joint are organised to allow only back and forth motion such as bending and straightening. This type of joint can be found between your upper arm and your lower arm, in the elbow. This type of joint is incredibly important as it allows an up and down movement, without this type of joint, we wouldn’t be able to move our arm up and down. Muscles are attached to this type of joint by tendons to allow it to contract and relax and be able to move the bone within this joint. Ligaments attach the bones in a hinge joint together, for example, the humerus and the tibia are joined by ligaments but they also have antagonist muscle pairs attached to them by tendons which allow the bone to move by contraction and relaxation of the muscles.
Imagining myself as a high school soccer coach, I would like to optimize my team’s kicking performance. Some players consistently kick the ball successfully with the correct use of power and accuracy. To ensure that all players are able to achieve the same optimal kicking habits, this paper will document (1) the effective and ineffective habits of kicking, (2) describe biomechanical based kicking assessments, (3) describe how these assessments will measure the effective aspects of kicking and expected findings, and (4) provide suggestions on how I may modify programming based on the insights gained from these assessments.
This skill involves jumping in the sagittal plane about the transverse axis. It consists of hip, knee, ankle, and shoulder joints. In the preparation phase in propulsion, the subject has flexed knees and hips which will need to be straightened by the strength of their corresponding joints such as the hinge joint at the knee joint. The hip joint is a ball and socket joint that bears the body weight and allows for jumping motion. During th...
In this position the athlete stands upright with their feet slightly separated and parallel, the arms hanging easily at the sides with the palms facing the body. When standing still muscles co-contract to stabilise the body and prevent it from falling or flopping due to the effects of gravity. The key joints that stabilize the body are the ankle joint, knee joint, hip joint, vertebral column and the shoulder girdle.
There are many aspects to the game of basketball and physics can be applied to all of them. Although to be good at basketball it is not necessary to play it from a physics point of view. Basketball players become good by developing muscle memory for the actions that must be performed in the game of basketball from years of practice. Nevertheless knowing some of the physics in the game of basketball can help a good player be a better player. In this paper I will cover the three most important aspects of the game, shooting, dribbling and passing.
Building such relationships is important in any field, but I want my ability to help to be rooted in methodical approach, researched plans, and an extensive understanding of the many factors that improve performance. I found myself unable to offer patients and athletes this area of expertise, which fuels me to learn and study at the graduate level. This program will provide me with depth, and a powerful understanding of these concepts. The biomechanics module is of particular interest because it will take an extensive look into the relationships between the body and various sporting technology, giving me a foundation in identifying unique strategies for specific individuals. And by combining this knowledge with later modules of advanced research methods and application, I will acquire the skills necessary to provide future patients and athletes with goal-oriented, contoured plans that maximize potential and
Physics is a part of everyday life. It is evident in the modern technological devices we use in every day experiences and objects around us. Although physics is understood to be only useful in the classroom, physics can also be applied to one the most popular activities on the planet, basketball. Whether jumping for the ball, or leaping for a slam dunk, the human body follows the same laws of projectile motion as do other objects. The sport that includes shooting, passing, running, and dribbling involves topics covered in physics such as force, friction, effects of air resistance, velocity, air pressure and energy. Basketball also involves factors such as projectile motion in making a basket, gravity and its effects on passing and dribbling, and Newton’s First and Third Law on passing and a number of others.
In this article, the authors highlight the importance of participating in golf-specific exercises to meet the physical demands of the game. Golf is characterized long periods of low intensity and short periods of high intensity, which can take a physical toll on the player if they are not mentally and physically prepared to meet the challenge. With the advancement in medicine and technology, research in the fields of motor learning, biomechanics and motor control has contributed in understanding the physical requirements of golf in relation to the muscles used during the game and it’s been helpful in developing training specific programs that can be useful in improving a golfer’s performance through training and exercise. Specific golf exercise is therefore useful to golfers and help to meet the physical demands of the game while preparing them mentally to handle the stresses of long walking, which helps reduce fatigue during play. Biomechanical investigations have focused on the components of golf swings, club head velocity and ball launch characteristics to devise accurate training programs that have increased the golfer’s performance and prevented injuries from describing appropriate physical exercise to professional
This research task requires that, through participation in skill learning and game play during the volleyball unit we have been required to observe and analyse the characteristics of skilled performers; receive feedback on weaknesses in technique and develop and participate in training activities that could correct these weaknesses.
