Biomechanics/Physics Assignment (Sprinting Biomechanics): Help Needed!

Here’s my proposal:

“I will look at the forces that impact upon the joints, ligaments and tendons and how some common injuries are caused as a result of some of these forces. I will also investigate how you can attain the most efficient sprinting biomechanics to prevent injury and lower your short distance sprint times.”

Good resources I can use, your knowledge on the topic or anything related to it would be much appreciated.

I would prefer something aimed at final year high school physics students (16/17 yr olds).

Thanks.

jgb99,

PM me your e-mail and I will send you couple of articles I have regarding biomechanics of sprinting.
I would suggest looking at Enoka “Neuromechanics of human movement”, 2002. Human Kinetics. Take a look at their site, and search for more easier text from biomechanics.

I think your being to general.

“I will also investigate how you can attain the most efficient sprinting biomechanics to prevent injury and lower your short distance sprint times.”

This is a f*cking huge undertaking. Why not try to answer a specfic question, ie. why ‘stepping over’ leads to faster sprint times?

you can do it, try focusing on the effect joint angle has on motor control and at given joint angles. should be an interesting read.

I agree ith Luca! Why don’t you use more “specific” subject: like spring model vs. propulsion model? Or, the role of glutes and hams? etc etc

From my syllabus guide these are the areas I can to cover (that are applicable biomechanics), just so it gives everyone a better idea of what I can do:

1. Movement:
• Rectilinear motion
• Motion in 2 dimensions (i.e. projectile motion)
• Gravitation
1. Structures and Materials:
• Properties of materials (i.e. stress/strain, youngs modulus etc.)
• Equilibrium (i.e. centre of mass, concurrent coplanar forces on bodies in equilibrium, principle of moments, general conditions for equilibrium, systems involving forces in two dimensions)

Bump…

EDIT: After seeing some of duxx’s articles I know realise how huge and complexed this project actually is! I think I will change my focus just to “the forces acting on the body (in particular the bones) when sprinting (i.e. start, acceleration phase, constant v phase)” Can that be effectively covered in 2000-2500 words?

BUMP

I don’t think it would cover 2000-2500 words, so I am adding another question to it: “the forces acting on the body when sprinting (i.e. acceleration phase, constant v phase) AND how injuries can be caused as a result of faulty biomechanics”

What about the following topic, which is easily done by your current level of knowledge:

*** Role of XXX muscle in sprinting***

• Basic biomechanics of running (time parameters: contact time, fly time, space paremeteres: stride lenghts etc) — sprint model vs. propulsion model — comparation btw start acceleration & top speed etc
• Anatomy of a XXX muscle and his anatomical function
• Function of a XXX muscle during running (on phases)

XXX muscle can be quads, hams and hip flexor! I think you can cover this easily!
