Treadmill science! What is the equivalent grade to running outside?

[@user-ow1jh8yb5j]

Nice video and pretty thorough I thought. A bit unrelated but something I find with amateurs on treadmills is the significant advantage from pacing at constant speed/effort vs outside or in a race where it varies a lot more.

Another great video and most people's treadmills become clothes racks. Stationary bicycles make a great place to stack things. If you're really interested in sports you're going to be outside, you're going to invest in adverse weather clothing and equipment. People like me install mudguards on our bicycle so we don't care about the rain or slush.

Wowie thank you for putting this together, very educational as always. Love the excel sheets to plug em numbers in!

Very interesting video. However I think I need to take slight issue with your though experiment. Running is different than cycling or walking because of the flight phase of each stride. During approximately 50% of each running stride a foot is not touching the treadmill. So during that portion of the stride the truck is not doing the work to elevate the runner, rather the truck has decreased the flight time by bringing the treadmill up to the runner's foot. If the athlete was walking on the treadmill there would always be contact with the treadmill so the truck would be doing the work to elevate the treadmill and walker. The same with a cyclist.

Where is the calculating website? I wanna use it. Is it expensive

Will running on a treadmill with an incline hurt my run time on flat ground outside?

Thank you soo much!

This video fails to explain how a leg stroke during one step on an inclined treadmill does the same work as a similar stroke on a real hill where the leg is actually lifting the runner up the hill, increasing the runner's potential energy in the gravity field.

how do you measure how much the treadmill bounces

[@Fastfitnesstips]

It's tricky but best to film it whilst running, then look at deflection at the midpoint as deviation from straight line (of the belt unloaded)

[@deank9938]

@@Fastfitnesstips could you explain by using a straight line please.

@@Fastfitnesstips Thanks a lot and as a tip to help other people you should make a video on it.
