A feature of Ivan's stroke has always been the full extension of the arm into the catch and through the power phase. The young paddler, by crooking his elbow a little at the catch, shortens the forward length of the stroke and applies a greater proportion of his power to the back part of the stroke where the blade is starting to pull water upwards (wrong direction of vector and sinks the stern).
Interesting video. But it must be stated that Lawler is drafting the younger paddler, so he’s putting out less power to stay at that speed. Potentially 10% to 20% less. Also, he could be applying greater power for each stroke. But more than likely, he’s also a more efficient paddler due to years of training. Having said that, it’s useful to study the current multiple-distance world K1 paddling champion, Fernando Pimenta from Portugal. Even at that very highest, most elite level of racing, he has a slower cadence for a given speed EVEN when he’s (normally) leading a pack. Then he just pulls away and wins, still maintaining his phenomenal form and power at a lower cadence. I just (age 66) started paddling seriously a month ago. I find myself paddling at low stroke rates (around 50) so I can better control my movements and attempt to feel the water better. Maybe that’s a good thing. But I do consider myself a CCRAP student, my technique mostly being, well, crap, leaving a lot of room for improvement! I currently average about 4.5 mph (4 knots per hour) and am concentrating on 5 mph as an intermediate goal. Appreciate this site!
