IT'S ALL ABOUT FRICTION. i am a "road" Inline speed skater. 10k to marathon and monthly 40+ mile. i appreciate the different view points i am reading, so i wanted to add. I have skated on ice only limited amount of time. Yet what i learned was that ice is always flat, and with turns, never changes. And on Ice the blades are also flat. The stride is very technical, yet seemly similar. a powerful smooth glide push, stay low to go fast. Now with Inlines, there are many many different elements. Indoors is similar to ice, always flat with turns. But Road is totally different. The elements constantly changing. I have to say the philosophy of a double push is valid and real. The difference is friction types. ice and a flat blade vs a road and rounded urethane wheel. The round tip of wheel allows you to smoothly transition energy from inside edge to outside edge. The amount of double push also varies from big to subtle, but always significant. My stride and body position changes like gears on a bike. Short powerful , long smooth, recover leg low to ground, or high. uphills, downhills, or flats, attacking, or pace I use variation of double push at different times, its a combo of elements that determine the best stride for the moment. The double push comes into play at different times, but it comes into effect. i have to also say that a true effective double push only works for advanced skilled skaters, with very good skates, because you are on edges. whether at 20+mph on flats or 40mph on downhills. My goal is to go as fast as possible all the time. So my stride changes.
You talk of variation on the road and then try to compare ice to an indoor roller track....the two are far apart. Have you ever tried to skate a corner that has been carved up by skaters?? Why do you think they have a Zamboni to resurface the ice?? (no different to roller skaters sweeping and cleaning an outdoor track before a race) What about ice temperature?? You talk as if there is no variation to ice skating. The ice temperature, temperature of the room (indoors)are critical to good performance on an indoor track. Also, ice temperature is relevant as to what sort is being performed/competed on that ice. Do you really think that the surface is perfect and flat for the outdoor events held on the canals in Holland and the likes(turns never change you say)? What about outdoor tracks for ice skating(snow,head winds etc) ? And just to repeat myself from another post, ice skates are not flat. Do some research please...See my comments about ice skates to Tommaso Leati. Cheers '
I totally hear ya Jason. and you are very correct. i did have more ice understanding. i didnt explain every aspect. there is huge difference indoors vs outdoors. i am from California, so inline is more the thing. i love outdoor because on the different elements like wind, hills and surface. and i watch and always have checked out ice skating in Holland! I love their marathon races, and especially the ultra-marathons. Overall i was sharing my opinion what i thought was difference about friction of ice and blades vs inlines and urethane wheels and how it applies to the video about a double-push technique. What is your opinion about the double-push technique?
+Reno Campos Hello Reno, do some reading about racing on ice on the canals between the towns in Holland. If you think that all those canals are smoothed out by a Zamboni before the race, then think again. To win a trophy in one of these races is an honour. I can't think of any roller skating race, that is held in such high esteem. The edges thing that you describe is an ice skating term....please. Roller skaters have to come to terms with that the fitness and skills of a trained ice skater is superior. I don;t mean that in a derogatory fashion, it is just the truth. A trained ice skater will always be better and faster going to roller skates than any roller skater trying to take on ice skating. Again this is not meant as a put down, it is just a matter of fact. I was skating unaided at 4 years old and have seen the differences between people who first learn to skate on ice or people that first learn to skate on roller. I know the difference and speak calmly and with knowledge. I like roller skates....It;s just that roller skaters are taking what I know and say as a personal attack. It is not and never will be that. Yes roller skaters are catching up. But if speed roller skating is oh so much different than ice speed skating, why do they get faster the more that they mimic ice speed skaters??? Roller skaters have come up with nothing that hasn't already been done by ice skaters. That includes practices to become fit as well as technique to go fast. Please don't take this personally, it is pure observation and it does not lie. What have roller skaters come up with that is new and hasn't been done by ice skaters that actually works???? The answer is..........zip, nada, nothing, zilch. Cheers, Jason
You need to have a chat with a real speed skater. Like Bart Swings. He will explain all the small things which make ice skating and roller skating SOOO different.
On first glance, I knew this video would be absolutely meditative. Then I noticed the Kerbal Space Program hangar theme playing in the background, and it somehow got even better.
It seems like each leg provides a push first on the outside edge and then on the inside edge. Always wondered about the double push. Thought there was a real trick but it is different and perhaps very difficult if you are not used to skating on outside edges. Useful skill for all skating types.
This is called triple pushes , he landed (kick) by center edge then follow by underpush then glide to rear-push. All three pushes mainly use leg power and arm swing which good for sprinter but not for long distance racing. Anyway he is amazing ! .....Long distance skating will always transfer more upper body weight ,save leg and arm energy.
That's pretty cool. Thanks much! BTW, it could be said your left leg is much stronger than right? I can see clearly the straight line when the left foot set down but looks a bit slant between wheels and boot in your right foot. Please advices how you feel that.
Very good, nothing to complain. Strong kick back in the beginning of the second part - seems you've been accelerating, looks great. I wish I could do it that well! (I've uploaded a video of me skating last year, just if you want to compare).
Super. Great video. Helped a lot. I am using old K2s, with a 2x110 rear, and 2x100 front. At my age (53), I thank God I can still get out there and do my thing. But, it is getting a little uncomfortable on my lower legs, inside knees. Getting the right turn is a bit harder now for me. Question: Can I do the 4x90mm and still get a good yet fitness skate yet, more maneuverable? Note: I have high arches. Need good relief support. Skate type? Thanks for any input from anyone
Check out Rollerblade Maxxum 90. A great urban skate. Molded shell, high cuff and comes with Hydrogen wheels and SG9 bearings. I've been skating on 90mm and they allow plenty of manuverability for the advanced skater. Hope this helps.
I think the arm swing kills the momentum the under push creates like here --> 0:21 the left hand hinders the left leg from pushing further with the outside edge of the left skate.
Skater seems to favor the right foot. On may strides, the skater appears to have a shorter stride length and less inclination when balancing on skater's left foot.
Astonishing. They're using thier recovering bent knee to execute a secondary push before the foot of the said knee contacts the ground to prepare for the primary push. And then the cycle repeats! So, in essence, their using their knees, their body's momentum (which activates the knee push), and the alignment of thier rollerblades (or feet, by turning it away from the perpendicular path) to push themselves twice in one exerted motion.
I agree with Jason. There is no extra effect from the "double push". Once you are convinced of the fact that both inline skaters and ice skater are subject to the same laws of dynamics and mechanics, and that the mechanism of their movement is the same, you can aknowledge that the the different circumstances are just second order effects. Why then do so much inliners belief in a positive affect? Is It because the dp makes them really different from the ice skaters? Is it because it's so hard to learn soem as a consequence it should give th something back in return? One thing is for sure: reel believers in the DP-religion are not easely converted.
harold klaucke I've gotta disagree with you Harold. The more refined my double push becomes the faster I skate. I am physically stronger than my coach equally as fit and he skates away from me with ease and I am a very competitive skater. The difference is his flawless DP.
+harold klaucke Funny enough no one ever wins an inline race skating as an ice skater. In addition the reverse applies on ice so your theories seem unfounded. Empirical facts against your "religion"...
I may be writing into a vacuum at this point, but it seems to me the issue is that a sharp skate blade (without rocker) will cut a straight line across flat ice, allowing the skater to apply consistent pressure on a single edge without any side-slipping, as long as the weight transfer lasts. That's why a speed skater on ice can take very long strides pushing on the same edge and do 400m laps in under 30 seconds. Even the grippiest wheels will not allow this kind of sustained pressure without losing power to slippage. Rolling from one edge to another while shifting the body weight is a way of increasing the pressure on the ground and thus the friction. The "double push" focuses on starting the stride hard on the outside edge specifically because that way the skate can pass under the body from one side to the other while generating thrust, so the body weight can be utilized to the maximum in keeping the wheels from slipping. Since a sharp ice skate doesn't slip, this technique is unnecessary in ice skating.
@@adamscotera2378 it sounds somewhat if not entirely correct. Firstly the ice blade is rounded i.e. has a radius of 20-30 metres hence the travel of the edge against the ice will curve slightly. It is right that with a correct technique there will be no slipping and inline wheels will not have the same friction. The rest also seems right but the last statement is potentially wrong ("this technique is unnecessary"). Muscle and body dynamics should probably favor the DP/inline body weight transfer with less lactic acid build up, less static load and more dynamic movement but it doesn't seem to work well in practice / not be effective. Why would be interesting to know however the skaters of today e.g. Kramer/Bergsma/etc have quite a different technique than the skaters had some 10 or 20 years ago with more weight transfer and less static movements. Within the bounds of the mechanics between ice/steel there have been room for technique improvements.
I cannot watch this video without wanting to lace up my skates. Thanks!
Inline skate is the best sport ever
Ahmed Alhouti I agree
Yeah
Perfect video. The slow motion has given us a good understanding on how to proceed to make a double push. Thanks so much!
il più chiaro che ho visto finora, finalmente almeno ho capito che cos'è la doppia spinta
Did anyone notice he had a thumbs up the whole time

I talked to Bart and some of Powerslide skaters in Vegas. He shared tips on training and some technique. He is awesome.

Ah, now I know how to do Double Push, nice video, thanks :-)

merci jai pu comprendre ce mouvement !
thats why I luv in line skating 🙌its all about freedom elegance and speed 🚘✈
What an instructive movie this is ！ I want to learn many things from his skating
Majestic as fuck
What I think? Great video capturing from up-front, which is an achievement in its own right.
Great video. Very good skaters

Follow up double push technique video with skater Ruurd Dijkstra Inline skate double push technique 2 Ruurd Dijkstra
Thanks for the video Nice scenery ! and a little bit exaggerated but I am sure it will motivate other skaters
Very good, nothing to complain. Strong kick back in the beginning of the second part - seems you've been accelerating, looks great. I wish I could do it that well! (I've uploaded a video of me skating last year, just if you want to compare).
amazing 😲😲 excellent video
can this form and strides be replicated on urban skates, or is it just used for the bigger wheels??
Yes but it won't be the same. The strides are really long because of the big wheels.
aaahh right, im currently using 72mm wheels and i just cant seem to maintain speed, migght have to get some bigger wheels
Damnn those guys are smoooth as butter
Super. Great video. Helped a lot. I am using old K2s, with a 2x110 rear, and 2x100 front. At my age (53), I thank God I can still get out there and do my thing.

Skating is the best game in the world
Brutal 💪💪
Sounds from Kerbal Space Program ?? :D
what country is this?

what camera did you use?
It was shot with a Sony FS700
How do you "shoot in slowmotion"? Haha, sorry I had to...awesome video though.
Good under push but can you tell me cleary step by step
Astonishing.

+Daniel Smith That guy in the other video where you made this comment is using the same technique, ya'understand?
Con nó đam mê mà không có ai dạy kỹ thuật cho nó
Очень большая раскачка вправо-влево
According to Wikipedia??? Really??? It must be true!!!
im just here to draw poses
no comments...

It's fake
How can this be fake
You can't fake the double push method and you can't fake a video
HAHAHAHAHAHA
