Usain Bolt vs Sean Eadie

Usain Bolt is the fastest man alive, but can a top track cyclists beat him? That was a question posed in the June issue of outside magazine. Most trackies know that a top track sprinter doing a 200M time trial will go almost twice as fast as a 100m runner ( both pretty darn close to 10 seconds, with the track rider going twice the distance), but the cyclists has the advantage of the standing start. The folks at Outside magazine went to Jim Martin, and former track racer and now one of the top cycling bio-mechanist in the world. Just do a google scholar search and you'll see. Jim has done extensive work in modeling performance, so from a theoretical perspective, he was the guy to answer this question.Jim took some power data from Sean Eadie, the 2002 match sprint world champion, along Bolt's 9.58 100M and ran the model. From a standing start, it makes sense that the longer the race gets the more likely the cyclist is to win, as the runners are already slowing down after 100M and the cyclists is just gaining speed. But it is a pretty close race at 100M. Who do you think won?

The answer is the cyclists by 0.16 seconds. Bolt pulls ahead at the start, but then Eadie Passes him at 89.7 meters. Jim's models are excellent, and can be be highly accurate, but when it comes down to 0.16 seconds, I think it could still be anyone's race. If those two men lined up at the starting line in top form, I wouldn't have much confidence in predicting the winner one way or the other. I would love to see something like this happen. It would be great or Gatorade, Red Bull, or a company like that could put on a race with Bolt and a top track sprinter.....maybe Chris Hoy or Gregory Bauge...Jaime Staff is known for heaving a blistering start, so he might be a good candidate.

Crank Cycling Time Trial Clinic

This clinic is designed to help you get fast! The focus is primarily road time trials, such as the 20K and 40k events, but triathletes can also benefit from this clinic. We will also devote a portion of the class to special events such as team time trials and track events like the 4K, 1K, and team pursuit. The morning session will be indoors at the Crank Cycling Training Studio and the afternoon session will be on the bike at Fiesta Island. This clinic features coach and exercise physiologist Sean Burke, coach and Fiesta Island TTT record holder Chris Daggs.  Classroom topics in the morning include: exercise physiology basics and energy systems used during TTs, on the bike training, weight training, flexibility training, warm ups, power outputs,  pacing, aerodynamics, and more. The afternoon "on the bike" topics include: proper starts, turnarounds, course management, TTT practice, and more. This clinic can accommodate a maximum of 20 athletes. To to make sure you don't lose out,  sign up HERE.

Does the language used by supplement companies encourge doping?

I recently got an email from an "endurance supplement" company.  The email was full of pro-athlete testimonials.  Both the language in the testimonials  and the language in other parts of the email reminded me of the language used for drugs. They kept using the word  "on".  " Shortly after going on XYZ supplement... I won XYZ race"    " When going on one  XYZ company's supplements,  you are guaranteed...."

I've received other emails from this company, and they always use the same "on"  language.     Regardless of whether the stuff  improves performance (and I'm skeptial of that), the language is similar  to what is used when talking about drugs.  My grandmother is " on"  anti-inflammatories and pain meds for her arthritis.  My uncle is "on" beta blockers for his high blood pressure.    Riccardo Rico was " on" CERA.

I think this habituates  athletes to being "on" something, and it can be a slippery slope.

My guess is that it is a marketing thing that they use, because if it sounds  kind of like you are using a  drug, than it must work like a drug, only this "drug" isn't  banned.  ( never mind the fact that if their products had the drastic effects they claim, they  would be banned from sport anyway)

The whole email kind of reminds me of  one of my favorite SNL clips.  The All Drug Olympics.

Fitter with Friends!

There was a great article recently in The Economist about group exercise, and how it is easier with friends. Basically the idea is that people can push themselves harder in a group than when they are by themselves....mostly because of hormonal responses.  They go on to explain a possible evolutionary benefits, such as hunting in groups.  The researchers in the study used rowers, and if  you are into that sort of thing, be sure to check out the  Indo Row program with Engine Room Fitness. But the results would likely be just as applicable to spinning, indoor cycling,  old fashioned step aerobics, or just about any synchronized group workout. Good news for group workouts huh?
