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

Social Loafing and Throwing Away Trash Social loafing occurs when people work together and when their “output” is combined leaving no one to feel solely accountable for the completed task. Social loafing occurs on many different types of tasks including ones requiring physical effort (Szymanski & Harkins‚ 1987). Due to social loafing effect we hypothesized that people in groups would leave behind more trash then groups of one to two people. We wanted to see if larger groups left more trash thinking

Matthew Mathis Mrs. Graph Graduation Project 17 April 2017 Baseball Throwing Injuries and How to Treat Them “Baseball is a game of physical capability‚ staying healthy is a whole new game” (Hamilton) Overhand throwing places extremely high stresses on the elbow and shoulder. In all throwing athletes‚ especially baseball pitchers‚ these high stresses are repeated many times and can lead to serious overuse injury. Unlike a small injury that results from a fall or collision with another player‚ an

10/17/10 Throwing Like a Girl 1. Fallow acknowledges the objections of feminists to the phrase “throwing like a girl.” Yet that is not the only derogatory phrase towards women. Activities such as football‚ hockey and hunting are mainly men’s sports too. It is clear that women gather more negative associations than the male population. Feminists challenge the phrase “throwing like a girl” because it is proven that men and women’s shoulders are aligned similarly and there are no structural differences

The article "Ankle Biomechanics during four landing techniques‚" written by Brian P. Self and Daniel Paine is based on a study trying to reveal new ankle injury prevention during landings in a variety of sports. By performing a series of landing tests‚ the goal is to learn how to prevent ankle injuries in sports through knowledge and understanding of proper landing techniques. Four landing conditions from 30.48 cm in height were tested. The landings include: the natural landing where the participant
