Ski Faster: How to Accelerate while Turning

[BallerSkier]

bs this guys is a retard, who the fuck skis wiht a stance like this, this guy id too old school, just ski and ull learn nobody taught me to ski i jsut learned and now i fall asleep on double diamonds

[skier9119]

kinda looks like ted

[thijsssie94]

how did you make this?

btw i go harder than 70 km/h ;)

[thijsssie94]

how did you make this?

[mmcg325]

awww only up to 70? i was hoping these tips would show me how to ski faster, not slower :(

[NigelXTufnel]

Looks like I'm gonna have to lose a lot of weight to ski like this.

Hah, Ben was my roommate at one point.

I realize it's tough to demand specific conditions and have a controlled environment, but it would be interesting to see how data differs with the angle of the slope and the different types of conditions.

in other words link your turns, throw your skis back to get on the other edge early and you will carry your energy through

[hornsofdavid]

he's turning wayyyy too late.....he's gonna miss a gate...

[rossdabossda2k6]

Nice work, good piece of technology. In the future might make my skiing a bit faster.

Good Vid

Hi, just to let you know that both New Scientist and Giz Mag have put up articles about this reserach on thier online magazines, good reading. I have also had papers recently published in the Journal of Sports Technology, the Journal of Computer Methods in Biomechanics and Biomedical Engineering, and the Journal of Applied Biomechanics if you are looking for more information.

Hi Matt. This is great ski biomechanics footage. Just wondering what level of skier this is in terms of FIS points. We can see the divergence in skis especially on his right ski (left turn) but then the impulse is quite proficient, in fact the acceleration off the right foot looks very good but then he seems to lack early direction. Would this be a fair analysis? Many thanks for your response. chris

Ben is a great skier, his web page is in the video information. About 50 FIS points when he volunteered to help me out, now 17 for GS. There is a slight right to left cross slope, the snow was hard and icy and he was going about 75km/h. Compare this to the virtual ski cross also a run later in the day with softer snow. Momentarily diverging skis don't appear to affect performance, when pushing the limits. Possibly measurement error from ski vibrations an early FMC bug that is now fixed.

Hi, thanks for the comment. Red is used to indicate that the force has a negative power or is acting against the centre of mass movement or simply speaking the force is slowing the athlete, when he skids to a stop the forces under his skis are slowing him. Sometimes there will be red forces even when he is accelerating if gravity is accelerating him more than the ski forces are slowing him. I will post some more videos soon. Matt Brodie

I can see that the length represents the magnitude of the force, but what does the red/green signify? For example at the very end when the skier does a (hockey) stop, both lines are red when I expect them to be green (if green represents +ve and red represents -ve)?

[BrodieMAD]

Hi, I am really surprised to see so many people are interested in skiing biomechanics. For those of you who liked this video, I have put up another one called 'How to ski faster? Forces?' that has better graphics and shows wind drag as well as ski friction. Enjoy, Matt Brodie

[luixxiul]

This kind of study will help even a kind to grasp how to ski better and faster.

I'll keep an eye on it:)

[tristanForSal3]

i'd say if you're skiing correctly you should accelerate before the gate and break afterwards while setting up the next turn

after done setting up pressure is put on the ski once more and acceleration happens as the turn is carried out BEFORE the gate

you probably already knew that though :)

[BrodieMAD]

One purpose of this project collect data that will either prove or disprove what athletes instinctively feel makes them faster or slower. The evidence I have collected so far on moderate slopes points towards more increases in speed being possible before and at the apex of each turn by using optimal timing for the application of ski pressure.

[skivirus]

i would like to see more informations :D could u brodie ?:D

[BrodieMAD]

I have several videos here on you tube. I may make some more information available in a month or two.

[skivirus]

ok, i will wait for ur update :) i am really interested. Pls can u tell me where from i can get ur book, or read it ?

[filidipcroatia]

So what is the skier really doing?

How come he is going faster?

[BrodieMAD]

For this analysis you will need to read the article I have written for the Journal 'Sports Technology'. It is to be published by Wiley-Blackwell within the next month. All the best, Matt Brodie

[BrodieMAD]

I will post more later this year, keep watching this space. In this run the skier reaches about 70km/h or 20 m/s see the speedometer on the RHS. His maximum G-force down this short course is 4g but on some courses 6g is reached.

[takwita]

Can you post more? Gforces, lbs/sq Inch etc...?
