During his career as chairman of the Department of Functional Anatomy at the Academic Centre for Dentistry Amsterdam‚ he was very productive in his contributions to our understanding of the biomechanics of the human masticatory system. First and foremost‚ however‚ he was

Biomechanical principles are what introduces the human body to motion‚ so the tennis biomechanics is essentially the science mechanics tennis technique. Tennis is a game in which two or more players hit the ball with rackets over a low net that is stretched across a court which is usually artificial surface. The tennis serve begins from the feet hitting the ground then continues up through the torso to the shoulders‚ then moves to the arm and then wrist. It continues right to the point when the ball

Triple Jump Biomechanics Triple Jump it is where an athlete sprints down a track‚ takes off at the board on one leg‚ hops‚ then again on the same leg before stepping onto the opposite leg and jumping into a pit of sand. This is called “hop‚ step and jump”. To be successful the athlete must be a fast sprinter with strong Gluteus‚ Hamstring‚ Iliopsoas‚ Quadriceps and Vastus muscle groups and core muscles: transverse and rectus abdominus‚ obliques and latissimus dorsi. They must also have the

BIOMECHANICS Biomechanics is the study of the body in a mechanical sense. This field attempts to make sense of the complexity of human movement by looking at the parts involved‚ analogous to the manner in which a car mechanic may explain how a vehicle works. The biomechanics of volleyball refers to the application of this field specifically to the movements in the sport. The movements of Volleyball are a complex combination of strength‚ power‚ agility‚ and finesse. Each of these components is

Lower Extremity Biomechanics During the Landing of a Stop-Jump Task The purpose of this journal article was to compare the kinematics of the lower body to the force that occurs during a stop-jump motion‚ the motion when an individual stops quickly and then jumps vertically. This motion can be seen below in Figure 1. The article found that large hip and knee flexion angles and initial foot contact with the ground do not have an effect on the impact forces during the landing of the jump. However

and is said to be one of the most effective throws in the sport. The technique employed to complete this throw successfully without injury to yourself or an opponent requires an advanced understanding of the sport‚ above average skill and unique biomechanics; which makes it a perfect topic for more extensive analysis. [pic] When performing the suplex throw there are three major phases that produce the collaborative move. There is the movement that gains control of the opponent and acts

Stride or No stride? The Biomechanics of Pitching. Brandon Ruston and Jacob Holland Mr. Post 2012 Will taking a stride while throwing a baseball increase you speed and accuracy of the pitch? Yes. The fact that you are taking a stride helps tremendously your speed and accuracy while throwing a baseball. The stride helps with changing your momentum from your back leg to your from leg which helps to keep you going to forward and add speed to the ball. The ball we use and the distance

This article deals with some of the basic Biomechanics involved with a Table Tennis Stroke. It breaks down the stroke into three components. 1. Backswing 2. Contact with ball 3. Follow-through The Role of the Backswing Key elements for timing and power production. the back-swing plays the primary role within all stroke techniques. It sets the stage for power production as well as provides the key element in establishing the proper timing of the stroke. Basic Biomechanical Principals Involved

Changes in Knee Biomechanics After a Hip-Abductor Strengthening Protocol for Runners With Patellofemoral Pain Syndrome It has been hypothesized by many that a primary factor contributing to patellofemoral pain syndrome is muscle weakness in the hip-abductor. Because the hip-abductors control hip abduction‚ it is hypothesized that they also control knee genu valgum angle during the stage of running known as the “stance phase.” A greater genu valgum ange has been purported to increase patellofemoral
