Lacrosse is the oldest team sport in North America‚ having been played by Native American tribes long before any European had even set foot on the continent. A century after European missionaries discovered the game played by Native Americans‚ they began to play it themselves‚ starting in the 18th century. From there‚ it evolved and grew in popularity from a very savage game that resembled war‚ into what it is today‚ a recreational sport played widely in America and other countries. As U.S. Lacrosse

Sports Biomechanics Biomechanics > Physics > Acceleration Acceleration Gravity Acceleration of an implement while in flight is constant and always -9.8 meters/second squared or 32 ft/s2 (feet per second squared); the act of gravity on the implement. Therefore‚ generally all objects fall to the earth at the same rate of acceleration‚ no matter how much they weigh. The force of gravity is always acting vertically; there is no horizontal deceleration in the absence of aerodynamic forces. Acceleration

We choose to do a plyometric fitness session for our duathlon training. Plyometric training is a system of exercise in which the muscles are repeatedly stretched and suddenly contracted in explosive movements to develop muscular power and endurance. We applied this into our session by using a range of explosive movements such as leaps‚ bounds‚ jumps and medicine ball throws. We made sure we had a good amount of reps to challenge the people training and enough of a rest in between each exercise to

Biomechanics of Injury: Notes Sports injuries are divided into two categories: Acute and Chronic Acute Injury Acute injuries occur suddenly when playing or exercising. E.g. sprained ankles‚ strained back and fractured hands are acute injuries. Signs of acute injury include: Sudden severe pain Swelling Inability to place weight on a lower limb Extreme tenderness in an upper limb Inability to move a joint through full range of motion Extreme limb weakness Visible dislocation/break

multimodal presentation I will be evaluating the video footage taken of my personal performance of the volleyball spike and I’m identify one major weakness in my technique and applying two biomechanical principles to justify why it is my weakness. Biomechanics applies to the science field in every sport; it is basically the principals and laws of mechanics about human performance. Though the evaluation of the video footage which was taken to show my personal performance in the volley ball spike‚ it

What is karate? In any sports that one performs it is fundamental to know the mechanics of it to be able to understand and produce the desired movements. When decomposing the word biomechanics we come up with the part bio (meaning living) so we study the mechanics of living subjects and the effects of forces (gravity‚ air resistance‚ ect.) on both living and non-living objects. This term project required us to record a short clip comparing experts to novices. Our "stars" are named Ricky Lew

Lacrosse is a sport that is becoming more popular around the world. Lacrosse is a fast paced game that requires a lot of movement. In some cases‚ injury can occur. A common injury that occurs during a lacrosse game is tearing your ACL. ACL stands for anterior cruciate ligament. ACL is one of the four main ligaments you have in your knee. While playing lacrosse‚ you tend to make very quick movements‚ which can cause this tear to happen. Without this ligament‚ your knee will be unstable and surgery

Iroquois Indians and Lacrosse Lacrosse is a sport played worldwide and is centerpiece of the Iroquois Indian culture. This sport involves using a small rubber ball and a long-handled stick called a crosse (aka lacrosse stick) and because this is a contact sport‚ it requires padding. The head of the lacrosse stick is strung with loose mesh that is designed to catch and hold the lacrosse ball. The object of the game is to score by shooting the call into the opponent’s goal. The stick can be used to

In 2015‚ I realized a long standing goal of playing on the varsity lacrosse team as a freshman. In fourth grade when I first started playing lacrosse‚ I had always dreamed of how far I could go. That dream of mine always stuck with me and it was my motivation to continually get better. When the coaches were separating the players to form the JV and varsity teams‚ they called my name to the varsity side. The only freshman to be called to the varsity side for the 2015 season. I had doubt and negativity
