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

Anyone can become a high velocity pitcher‚ there’s just a lot of work that goes into it. As Nolan Ryan once said “Pitching in the big leagues is a dream. Preparing to pitch in the big leagues is a nightmare.” Mechanics are the key component to the success of a high velocity pitcher. Mechanics of High Velocity Pitchers There are six things high velocity pitchers

Journal of Biomechanics‚ 35 1631-1637 Purpose The purpose of this study was to discover the role and use of arm motion on the performance of the standing long jump and if it improves the distance of the jump. The study also investigated the additional benefits of the use of arms in balancing the body for optimal landing and different forces during the take off phase. Methods The subjects were three unskilled

Force: This can be defined as a pushing or pulling action that causes a change of the state of a body. A long jumper who wants to increase their degree of force will need to increase their weight‚ but this can negatively affect their speed‚ so it is vital to get the balance right. The law of reaction also applies to movements that occur in the air. In these situations the equal and opposite reaction is shown in movements of other parts of the body. A long jumper‚ for example‚ will bring the arms

What is a Biomechanical Analysis? Biomechanics is the study of how parts of the human body moves‚ bears weight and how the various parts of the extremities move The study of biomechanics is important when determining what causes injuries and therefore how we can prevent them re-occurring. This is especially important in elite athletes but can be a major cause in recurrent injuries in the less gifted amateur athlete. PhysioWorks physiotherapists and podiatrists have additional training in

“Biomechanics of a Lacrosse Shot” Lacrosse is defined as a ball game invented by American Indians‚ now played by two teams who try to propel a ball into each other’s goal by means of long-handled hooked sticks that are loosely strung with a kind of netted pouch (Farlex‚ Inc.). Behind every shot taken in a lacrosse game‚ elements of biomechanics are implemented. Biomechanics is the “sport science” field that applies the laws of mechanics (movements‚ body angles‚ joint positions‚ etc.)‚ biomedical
