The Model E becomes available in early September

I won't be back on the indoor rower until next spring after the upcoming rugby season. My best was 17:56 for 5k, next summer I will try to get under 17:50.

I have been looking at how to factor age and weight when comparing rowing times. The following link is for 2000m, but I mainly row 5000m, so I will linearly extrapolate (not 100% accurate but acceptable).

http://www.concept2.co.uk/racing/correction.php

Two example rowers are shown below

 

Age

Weight

Time

Person 1

31

100

17:58

Person 2

33

70

22:08

  • If Person 2 were to be rowing at the same level as Person 1, what time would he need to do to be on a par with Person 1:

17m 58s  = 1078 seconds

Weight adjustment: 1.059/0.979 = 1.082*1078 = 1167 seconds = 19m 27 seconds

Age adjustment: 1.6seconds *(5000/2000) = 4 seconds.

So person 2 would have to complete 5000m in approximately 19m 31 seconds to be on par with Person 1

  • Alternatively, assuming Person 2 were to travel on a very fast spaceship and therefore didn't age compared to those on Earth, how old would Person 1 be before he slowed down to Person 2's speed.

22m 08s - 17m 58s = 250 seconds

~ 100 seconds over 2000m

Person 1 would have to be around 73 years of age before Person 2 can land his spacecraft and win!!

I'd been trying to work out how the Concept 2 rower got its calorie calculation and came across the following links

http://www.concept2.com/05/rower/service/PM2_service.asp

http://www.concept2.co.uk/guide/guide.php?article=watts_conversion

  • 5000m in 18:39 minutes gives a power output of 250 watts

and a calorie consumption of ((4*250/1.1639)+300)* (18.66/60) = 360 calories (1160 cals/hour)

  • 5000m in 18:04 minutes gives a power output of 275 watts

and a calorie consumption of ((4*275/1.1639)+300)* (18.07/60) = 375 calories (1245 cals/hour)

 

This is for an 80 kilo man, for a 100kg man I would substitute 375 for 300, giving ~25 extra calories over 18 minutes. The following links are slightly more complex and take into account your age and weight.

http://www.concept2.co.uk/training/bmr_calculator.php

This calculates that I would burn 454 calories for a 19 minute row at a 1:53 split

A Mars Bar has around 300 calories (449 calories per 100g, normal bar 62.5g)
