Say you way 100 kg fat % 15 then your leanbodymass is 85 kg. That,s all.<br /><br />Question: Could someone have al look at the watt production of an 5.44 2 k and a 6.29 2 k. the firts done by a 100 kg athlete and the other by a 78 kg athlete.

Pity he's not 110kg then isn't it, then your previous claim may have been true...........alas it isnt<br /><br /><br /><!--quoteo--><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td><div class='genmed'><b>QUOTE</b></div></td></tr><tr><td class='quote'><!--quotec-->Question: Could someone have al look at the watt production of an 5.44 2 k and a 6.29 2 k. the firts done by a 100 kg athlete and the other by a 78 kg athlete. <b>Someone one this forum is again talking out of his a**ho**.</b> </td></tr></table><br />

And he rowed that time and you rowed 6.29 at 78 kg. <br /><br />No IFIFIFIFIF but facts.<br /><br />If you row faster of if you become lighter and row relative better then you can do the mat again, no sooner.

It looks as though the calculations come out _very_ close, even for powering boats, though. I nip Joan by a couple of seconds, not much.<br /><br />I guess I had Joan as having more LBM in my calculations. Don't know why.<br /><br />Interesting result! _Very_ encouraging, given my interest in rowing on the water as a heavyweight.<br /><br />ranger<br /> </td></tr></table><br /><br />What is your weight going to be when racing OTW?<br /><br />Men and women can't really be compared OTW, because of the LBM% differences. Though I suspect that if the men had to wear a weight bearing harness of some sort that equalized the LBM% then the times would get closer. Though that's mostly a problem at the start, once things are moving along, a relatively small amount of additional weight is not a huge liability, it's the additional useful muscle mass that makes things go.<br />

I think I've seen it calculated by using weight and waist measurement, I'd be very curious if the IR device came up with teh same number. The gadget does sound like it has a higher "cool" factor. 8) <br /><br />There are some impedance measuring devices in use at the Elite athletic training levels that give a pretty detailed readout. One thing that was mentioned as being useful was that with experience and baseline data the coaches were easily aware of who had not been getting enough sleep or were out drinking the night before.

I really think Ranger could be a nice person to chat with on the forum If he only came down from his cloud heigh up in the air. Just stickts facts eh.<br />A will geive it another go ray.<br /><br />Someone was going to do a 2k race this weekend. He prepared well and stayed close to the veniew. He stayed with his son and freinds. And was giving up all about how nice his family is enz. <br />But he seems to end up in some sort off Cra**h*** and his son was not decent enough to let his father sleep well and prepare for the race. <br /><br />Imagen some relative off yours preparing like ranger does and then not having the decency to let the man sleep <br />

By my calculation, at a weight of 165 pounds and an LBM of 159.5 pounds, you had 3.333% bodyfat. That is not even close to a healthy situation. According to what I have read (but, please, do your own research), the lower limit for a healthy male is somewhere in the 7-10% range. Elite male bodybuilders seldom get as low as you have (4-5% is common, though), and when they do it is only for brief periods prior to contests. From time to time, we read in the press of bodybuilders collapsing on stage or after a contest, even dying. There are many factors that can go into those critical events, such as dehydration and electrolyte imbalances (e.g., hyponatremia), but low bodyfat from "cutting" is also a factor.<br /><br />I think everyone who posts here, even those who may have expressed some doubts from time to time, respects your accomplishments. That being said, making weight for an event is not worth risking your life. Hours of stepping, skipping, and water deprivation to make weight are potentially life-threatening, particularly at that BF percentage. I understand that you have given up on making weight for this season.<br /><br />Please don't take offense, but I hope that you will pause and re-evaluate your training/hydrating/nutritional methodologies. I am something of a skeptic when others diagnose me as a "fitness addict," because the ones making those statements are usually lard-assed couch potatoes. I am equally skeptical of casual statements regarding body dysmorphia or similar disorders. I am not offering any such diagnosis (or even any criticism). First of all, I am not qualified to make one. I am, however, a reasonably well-informed layman, and the information I have seen tells me that you are (or were) in a potentially unhealthy situation.<br /><br />

I'm not sure where I got the erroneous idea about BMI, and apologize for disseminating it on the forum.<br />
