SIS 3 GRUNTING VS NON-GRUNTING

WHY GRUNT

Grunting during physical activity is beneficial to the amount of force and energy expelled from the athlete. Maximal energy is released due to the act of grunting triggering one's adrenal gland in order to relase adrenaline throughout the body. The release of high amounts of adrenaline into the blood stream result in an increased amount of energy throughout the body, producing maximal strength and power by the athlete. This is due to the selective human respose of fight or flight, this is triggered whilst grunting, allowing a burst of adrenaline to flow through the body and released into the athletes muscles, therefore increasing the evident strength and energy produced.

Grunting allows for a psychological advantage over a participants opponent, by acting as a distraction effecting their timing and outcome. Grunting diminishes the opponents ability to respond with their full athletic potential, due to the fact that humans struggle to more than one stimulant at once.

Grunting during exercise also increases the participants heart rate. This improves and increases the blood flow around the body and the acccessibily of blood and oxygen within the muscles. As grunting produced an increased heart rate, this beneficial to the to efficiency of movement of the athlete.

Grunting while participating within a physical activity increases the ability to improve the accuracy of the athlete's technique, the efficiently of the respitary system and improves the tightening of the surface of the athletes muscles, therefore producing more force.

POSSIBLE METHODS FOR COLLECTING DATA

The use of an accelarometer in order to test the force application through the use of a tennis raquet and a softball bat.

Limitations: There are evident potential limitations whilst using the accelarometer, these of which are due to the small force range that the accerarolmeter can track. In order to reduce this limitation, there would need to be implementations applied to prevent the accerarometer from maxing out and not delivering the complete results.

Benefits: The use of the collected quantative data would allow for a clear and comprehensible comparison between the two trials, being non-grunting and grunting. This will permit a full investigation concerning the effect of grunting during a physical action.

The accelarometer being attached to the identified peice of equipment would permit for the effects to be tested. The effects would be made evident through the collected quantitive data, whether an increase in force was evident when the act of grunting occured compared to a non-grunt during the specific selected physical action.

Dynamometer

Limitations: Each subject could potentially have different definitions and techniques of grunting, therefore producing a greater variation within the results produced. Due to some subjects not grunting to their full potential, this effects the reliability of the results and does not allow for fair comparisions between participant's results.

Benefits: Through the use of the dynamometer, there will be a clear difference between the effects of non-grunting and grunting during force application due to the simplicity of the collected data. It can be clearly established whether grunting had an effect on the force applied, due to the ease when analysing and observing the results collected, as the produced results is in quantitive whole numbered data.

By permitting all participanting athletes to use one consistant dynamometer, while obtaining a focus on a grunting vs non-grunting aspect. The results produced will define and conclude whether grunting benefits the force application, this will be made evident if there is an increase in the dynamometer value due to the grunting of the participant.

Throwing a shot-put

Limitations: Each subject has the potential to use a different technique when throwing the shot put as some may use a standing start, some my use a run up and others may spin, this must be a controlled factor during the experiment. The effects of this corruption can cause invalidity, unreliability and inaccuracy through the results produced. This is due to the data obtaining other factors acting on the dependent variable the alterations of techniques varying from each participant.

Benefits: The effect of grunting on a physical action and force application would be able to be evidently identified due to the permittance and the ability to simply compare the results between the two trails, being non-grunting and grunting.

The effect of grunting will be observed through the use of two trails comparing the varitions of grunting and non-grunnting during a force application. The effects of grunting will be indetified through observing whether there is an increase in distance produced during the shot put throw incorperating a grunt. This will determine an increase in force applied due to the effect of grunting.
