Resistance

[forza]

I realize this may be difficult to answer, but if a strong 200lb. man in good condition does an all out max sprint on the BikeErg AROUND how long might he last before having to stop (ballpark) and would the stop be due to muscular failure in the legs or from being winded?

Not quite sure what you mean but the fastest verified 200m on a Bikeerg is 12.8 seconds (1:04/1000m or around 1335W) look at: https://www.rankedworkouts.com/ This website lists all ranked distances/times across all years. I find it very useful and certainly an underrated website.

Hope this helps.

At max pace, no human will be able to go beyond 8/9 seconds before he/she starts to slow down. From there you can still go on, but between 30/45 seconds, you should not be able to keep going.
Search on youtube for 1k events on the track, bike, you can find nice examples of people complete fall off the bike. Takes around 60 seconds on worldclass level.

Thanks. I also wanted to add that I phrased the questions in those terms because I am unfamiliar with things like drag and watts,etc.
I also wanted to know what would fail first in a max effort all-out sprint --legs or wind.

I also forgot to mention with the damper on 10. I am trying to determine if the resistance is sufficient to stimulate hypertrophy (buid muscle) in the legs.

... I am trying to determine if the resistance is sufficient....

There may be a slight misunderstanding of how the erg works here? The lever controls air flow and that simply impacts how fast the flywheel slows down. There is no change of resistance at all. If the flywheel slows down quicker/more (on 10) then you need to work harder to speed it up again...and the way you do that is to accelerate the flywheel faster with a quicker drive. Achieving a quicker drive against the same resistance "feels like" more resistance and certainly demands more power. Several on here have experimented with using low rating, high drag, maximum pace for very short intervals to simulate a weights/resistance workout. Martin is a recent exponent who has done this successfully. But take care as it can easily lead to a back injury.

I'm glad to see there's a website that does this. Thank you for posting it!

What you are describing is in sports science called a Wingate Test, or a Wingate Anaerobic Test (WAnT). In contrast to a time trial, like the 200m TT mentioned above, it requires the athlete to go all-out all the time. This typically leads to a power-time profile that has a maximum in the first 5 sec and then drops steeply. The usual Wingate test lasts 30 sec or 60 sec. The duration is not important for the Peak Power, but it affects the Mean Power and the Fatique Index (=ratio of lowest 5-sec power segment to 5-sec peak power").



I don't think the athlete is really forced to stop, but he will feel fully drained. Because the Wingate test is anaerobic, it will feel as if the legs fail. Breathing is not the factor limiting peak power. It's the phosphagen energy (ATP-PC) system that is running out, which functions without oxygen. However, only a limited amount of ATP-PC is available in the muscles and during a maximal exercise the supply will be exhausted within 30 sec. Meanwhile he is gasping for oxygen to sustain power as much as possible.

Note that Wingate tests on a rowing erg gives a peak power that is lower than on a cycle ergometer. This is because the power developed in the drive is averaged over the duration of the full stroke. The power measured over the drive phase only is a factor 2-2.5 higher.

I would say that it depends on how big you want your muscles to get.

I come from a cycling background, and regular old road cycling (flats and hills, which I'm sure the BikeErg can successfully simulate) does improve both my definition and bulk (obviously more in some muscles than others) but to get really big like trackies, you most certainly need to lift weights.

Thanks, what do you mean by low rating and high drag? and why would this lead to back injury?

That's a rowing ergo answer to a bikeerg question.
