What I noticed from Janne's latest tapes...
I just watched some Beitostolen relay mpegs.
Five things stuck out for me: 1*Seemingly slow classic tempo---they seemed to use moderate but strong-pulse arm and leg action. Tempo seemed the same or even slower than for skating. 2*How long the heel stays down in skating and how much nice swing/rhythm they seem to have. 3*I noticed some of the lead skate men using V2 and others using V1 on uphills at the same speed. --So far for me I've noticed this fall that my 1/2 km speed trials up moderate hills give the same times for V1, V2 and V2A. I suppose I should do some longer timed runs to see what's really going on. 4*They sure don't bring the feet very far back in to the center. --Not the winners anyway. I noticed that the women who finished farther back often had the 'knock knees' look and also brought their V2 foot way back in to their centerline. The winners didn't! 5*How closely the men's pack stayed together and how strung out the women got. Maybe it shows that for elite men the speeds are so high that drafting is a major factor or that aerobic fitness is basically on par at the top. Either way (or both ways) the result might be that the men use POWER for their tactical moves. Nobody can really drop the others so they wait for tactical moments to use explosive bursts. The women's relay finished this way as well between the top two. (The rest were quite strung out.) The winner didn't drop the other skier she just exploded a jump and got a gap at the end. Her jump was quite longlasting and seemed to involve several attacks within the one overall attack and didn't seem aerobic in style but pure power. Their motors seemed to be on par, but the winner did seem to have bigger musclesize. Of course the winner also drafted most of the way: so maybe it was just a case of a sprinter mooching til the end. Actually, I didn't finish the men's relay--my mpeg feed got an error I couldn't sort out. Maybe elite observations don't really apply to us mortals. But these vid's are cool to see what's going on at the top and how it might shake out for them and maybe we can get a few hints as well. Maybe they teach a lesson like for instance we should mostly hope that our U.S. guys have the POWER this season. I suppose we mortals simply have to do what is fastest for us then try to keep doing it. : ) Seeing different elite skiers using different modes on the same terrain to go the same speed might also encourage us to just use what works. -- Jeff Potter **** *Out Your Backdoor * http://www.outyourbackdoor.com publisher of outdoor/indoor do-it-yourself culture... ...offering "small world" views on bikes, bows, books, movies... ...rare books on ski, bike, boat culture, plus a Gulf Coast thriller about smalltown smuggling ... more radical novels coming up! ...original downloadable music ... and articles galore! plus national "Off the Beaten Path" travel forums!
