A Visit To Mathmagic Land
Oh hello there. Allow me to introduce myself. I am Professor Ludwig Von Drake. I have given Jeff the day off, because I wanted to chat with you about something you might find interesting. This post is dedicated to Jonathan Dichter and the amazing weight loss he has achieved over the past year. Have you ever thought about how weight loss can help your joints? Let's talk about heel strike.
Heel strike is when the foot makes contact with the running surface. Your body weight effects that. Forces of 2 to 3 times you body weight will impact your joints with every footfall. So lets split the difference and have some fun with math shall we? Here are our friends Jeff, Jonathan, and Bryan.
We know that Jonathan and Jeff have been posting their weight. Bryan whose weight we do not know, is also a Gazelle. (I personally think he could out run Mufasa) Therefore we will leave him out of our little equation.
Jonathan started his weight loss efforts at 370 lbs. If we assume 2.5 lbs of force times his starting weight we have an impact to his joints of 925 lbs per heel strike. Right now your thinking Holy Cats! But wait there's more and it's good news.
This week Jonathan posted a weight of 288 lbs, if we do the math, we will see that Jonathan is currently impacting his joints with 720 lbs of force. That's an 82 lb weight loss resulting in 205 lbs less force affecting his joints. Wow, isn’t that amazing? And he's not done yet. Those numbers should give you some motivation. An 82 lb loss is fantastic but think about how much longer (and further) Jonathan's joints will be carrying him in the years ahead. And as I said before the best part is he's not done!
Jeff started off at 230 lbs with 575 lbs of force. At 200 lbs he is now hitting his joints with 500 lbs of force.
These numbers add up (or rather drop) fast. Just think about how much easier runs will become for those of us who are still working on weight loss.
Remember, every pound you add or lose affects your joints by 2-3 lbs of impact force.
So get out there and make good choices today.
