Today's video "Biomechanics of a Soccer Kick" is a bonus video for our Biomechanics for Beginners Series. This crash course series is designed to help students, athletes and sportspeople gain a better understanding of how their body works and how we can use physics, science and Biomechanical analysis to improve performance (And decrease injury!).
In this video you'll learn how to analyse a sports movement, in this case it's a soccer kick. We'll review and apply each of the 4 main Biomechanical principles we've learnt about and find out how to improve performance. This is useful for anyone studying VCE PE, HSC PDHPE, GCSE PE or similar courses in Year 11 or 12 as well as first year uni students!
What you'll learn in this video!

Your video helped me out so much trying to understand my mistakes while trying to improve my kicking skills. Thank you so much man.
I’m so glad that it helped you! Keep practising 👌🏼
Thank for this detailed analysis. Very clear and comprehensive.
But I wonder why you have not mentioned the lever created by a hip (I think @djfunkychicken mentioned it in his comment). I think that calf is providing a good acceleration for the foot, but the main rotator and source of torque must be a hip. I am no expert though...
What amazes me the most is that idea of getting a reaction from the ground as we land our planting foot. It is amazing how our bodies know the ways to multiply its abilities, by using external levers and by transforming our own inertia.
Can I ask you, though, do you think this reaction from the ground that is used during the football kick is the same idea that javelin throwers use?
And do you think it would be a correct assumption that, if the kicker would gain the same run-up speed before the kick, but instead of running up, he would be standing on a moving platform that moves with the same speed as a run-up, and as the platform reaches the ball he kicks it (speed of platform adds up to the speed of foot) - the kick would not be as powerful, because the kicker would not be using a reaction from the ground?
Just like volleyball players make jump serves in the air - they have no possibility to support their body against ground, thus they cannot get that reaction. That's why I think they cannot create as much power as they would be if they served on the ground with a good run up.....
Wow a lot of insightful questions! I’ll do my best to answer them.
You are correct, the hip is a major lever but I think the knee is easier to understand the concept of levers with. And I didn’t cover torque in this video, which is certainly related to the hip joint.
Yes the ground has a part to play regarding actions and reactions. You can still kick with power with a volley or bicycle kick in the air but these rely on actions and reactions of opposite body parts rather than the sudden stopping of the planted foot into the ground.
The moving platform concept is interesting but it may have a similar or increased power due the increase acceleration. Remember the equation F = MA . The A (acceleration) would be bigger in this scenario and therefore F (force/power) would be also.
Hope that helps 😊
This is how AFL players kick a football.. literally no football player kicks like this. If you kick wanting power you follow your body through the ball and continue so until your kicking leg lands first.
Illogical to stop your approach motion to keep your balance or not to fall over either! That would be like saying to punch hard but don't follow through ! Or like the shot put guy stopping his motion on release of ball.
Your knee should be fully bent/cocked and kick with your knee down to the ball.. then drop your foot.. the same principles of a a golf swing or tennis serve.. because this flexion maximises acceleration speed on ball contact. It's the hip thrust that provides torque and the counter motion of non kicking shoulder should match speed of kicking knee for equal rotation which creates far better accuracy.
Hey thanks for your comment! Some good points. This video is targeted at school students, hence the level of detail presented. And AFL and soccer kicks use a very different technique. Yes, several key biomechanical principles apply to both but the specifics vary considerably between driving kicks, curve kicks, kicks for distance, chips, knuckle balls, passing, shooting etc. But I appreciate your passion for this!
@@PEBuddy Sorry I didn't mean to offend your expertise either. Yeah It's a subject I'm very passionate about because i've seen many teach much much worse at grassroots level.. setting bad habits into place or giving little understanding as to why
No worries! I will admit that my technique is certainly not perfect but I do manage to score the odd goal or two 👍🏼
