Research Question:
Is there a relationship between the circumference (cm) of football player’s gastrocnemius (tensed, preferred foot) and how far they can kick a football (m)?
Background Information:
The investigation of the distance at which a football player can kick a football can be done in many ways. The first way would be to literally measure out the distance of how far the player kicks using a trundle wheel or a measuring tape. However, a far more practical way of doing this experiment is by using a speed gun to calculate how fast the ball is travelling, and record the time it takes for the ball to land onto the ground. Using a speed gun, one can calculate the speed at which an object is travelling and use that information in n equation to find the …show more content…
Controlled Variables
What is the variable? How will it be controlled?
Age All participants will be in the age range of 16-18 years old
Clothing/Apparel All participants must wear football clothing (shirt, pants, shoes)
Rest between trials The rest in between trials is fixed to 30 seconds, this is because the player might begin to feel tired after a few trials, and an ample rest period is optimum in order to create a fair and reliable test.
Weight of the football The weight of the ball is fixed to 430 grams, as per FIFA regulations
Equipment All equipment is the same, speed gun, stopwatch and the brand of the football.
Experimenter There will be 3 different experimenters, each recording the time and measuring the size of the player’s calf.
Preferred Foot The participant must use the same foot to kick the ball to create a fair and reliable test.
