I decided on how I wanted to figure the wattage of the long cycle clean and jerk (LCCJ). Whereas before, I calculated the snatch based on one stroke, but couldn’t figure the LCCJ, because it’s a two-stroke movement. But since I rack the weight for an undetermined length of time before I jerk it, I didn’t feel comfortable assigning a time count for the whole movement.
The solution, of course, is to just beak it down into the two movements and calculate the outputs of each, then add them up. So: you clean, which is about a one meter arc, rack, then jerk–where the weight travels about another meter.
From earlier, we remember that:
1 kg x meters squared
————————– = 1 W
16 kg x 1 meter squared
————————— = 16 W
1 seconds squared
So then you add:
16 W (for the clean) + 16 W (same calculation for the jerk) = 32 W (total)
Pretty simple, eh? As we saw in the earlier post, one 16 kg snatch generated 64 watts, and therefore 25 of them totalled 1600 watts.
For the same amount of LCCJ you would be causing 32 W x 25 LCCJs, which would equal 800 watts. Half the wattage of the snatch. So you can see why the snatch seems so intense.
Looking back I see that I estimated about 25 16 kilo snatches for one minute, and about 10 32 kg LCCJ for a minute. You know, I don’t remember now if that was one minute each arm (for a total of 20), or just one minute. Well, whatever. For now let’s just compare 10 LCCJ (32 kg) to the same minute for 25 snatches (16 kg). That’s an interesting comparison.
As stated, one minute yielded 25 snatches from the 16 kg kettlebell. Using the method for LCCJ calculation for 10 LCCJ (32 kg), we get:
32 W + 32 W = 64 W (one LCCJ)
10 of those, or course, gives you:
64 W x 10 LCCJ = 640 W
Hmm. That’s compared to 1600 W for one minute of 16 kg snatches (25 of ’em), and one minute of 16 kg LCCJ (if you did 25 of them) giving you 800 W.
Veddy interesting. But here’s the thing: the perceived level of effort for doing those 10 32 kg LCCJs is much higher than the 25 16 kg snatches, at least for me. I guess what that means is that I need to keep getting stronger… 🙂
