Acceleration is an essential component in many different field sports including games such as rugby, soccer, American football and tennis (Spencer, Bishop, Dawson and Goodman, 2005). It is widely considered the most important attribute in team sports (Wilson, Lyttle, Ostrowski and Murphy, 1995), therefore the ability to enhance it would be valuable to many sporting events (Cronin and Hansen, 2006). An athlete’s ability to accelerate is dependent upon numerous factors, including technique/body position (kinematics) and the force production capability (kinetics) of the body (Cronin, Hansen, Kawamori and McNair, 2008). Important kinematic factors that affect acceleration performance include step frequency and step length (Hunter, Marshall, and McNair, 2004; Murphy, Lockie and Coutts, 2003), duration of the stance phase (Murphy Lockie and Coutts, 2003), position of foot strike through the athlete’s centre of mass (Chu and Korchemny, 1993), knee flexion angle before and after foot strike (Murphy, Lockie and Coutts, 2003), the magnitude of hip extension at toe-off (Vonstein, 1996), the angle of take-off of the athlete’s centre of mass at toe-off (Hay, 1985) and trunk lean progressively decreasing from 45⁰ to 5⁰ (Baechle, and Earle, 2008).
Kinematic factors, in particular trunk flexion may change slightly when an athlete fatigues, as fatigue of the trunk musculature has been shown to cause an increase in trunk flexion during running (Hart, Kerrigan, Fritz and Ingersoll, 2009). Koblbauer, Schooten, Verhagen and Van Dieen (2013) found that an increase of just 4⁰ trunk flexion whilst running in novice athletes can increase risk of injury of the lower limbs and back musculature by exposing the knee to increased load (Z...

...ervention. Furthermore future research needs to identify if the small change in trunk flexion found in this study could lead to any long term effects on sprint kinematics. This will allow coaches to understand how weighted vests may impact on sprint kinetics and how it can be manipulated to increase acceleration power and decrease risk of injury.
In conclusion there was no significant difference in trunk flexion at 5%, 7.5% and 10% (p=0.83) resistance in resisted vest sprint training compared to unloaded sprinting. The study highlights that low percentages of resisted sprint resistance will not cause injury through change in trunk kinematics. Although trunk flexion did increase slightly to the response of an external stimulus, recent research (Koblbauer, Schooten, Verhagen and Van Dieen, 2013) suggests this increase is not enough to cause concern for injury.

training of an athlete Essay

- Training of an Athlete When training a football player, or any athlete for that matter you want to make sure that they are not smoking. Smoking is very harmful and addictive to the body and causes increased airway resistance. When smoking is done it takes 24 hours to clear the poisons from 1 cigarette. The effects of smoking can be damaging for life by causing heart disease, cilia damage, throat cancer and other many life-treating effects. If an athlete is smoking the results of smoking they will see will be decreased endurance, decreased ventilation, decreased Max VO2, and decreased oxygen capacity....   [tags: essays research papers]

Essay about How Basketball is Affected by Biomechanics

- ... (Bartlett, 1999). The effect that various components, i.e. instantaneous acceleration, has on the various actions in basketball, i.e. changing direction when crossing over, dribbling. Effect of Velocity/Acceleration Basketball is a sport which relies on rapid transitions from defense to offense in order to score. Speed and agility is a massive component of the sport. Therefore, by carrying out a biomechanical analysis of the act of sprinting movements in the sport and learning how to improve upon them, it becomes possible to improve an athlete’s performance....   [tags: athlete’s performance, position]

Formal lab gravitaional acceleration Essay

- Lab #5: Gravitational Acceleration Preparation: In preparation for the first part of this lab involving the Atwood's machine our team started by discussing the effects of the masses on the results of the machine as requested in question 1 of the lab manual. We believe that if the two masses were equal there would be no motion of either of them when released. However we believed that if the two masses were not equal, the heavier mass would fall downward pulling the lighter mass upwards. Below as requested by question 2 is a free body diagram of both situations Masses Equal Masses Unequal The tension on mass 1 is equal to the tension in mass 2 due to the same string attaching both m...   [tags: essays research papers]

Essay on Acceleration

- Acceleration Introduction: Acceleration is the rate of which the something increases or the rate in change of velocity. Newton's second law is m = f/a which means that Force is equal it Mass x Acceleration, the equation for this is N = Kg x M/S. Prediction: My Prediction for this experiment is that it will be directionally proportional relationship, so if you double the force of Newtons you can double the speed of the car.
