Caleb Ewan's Sprint Position - Revealed through Kinesiology

Is Obesity Really A Problem? A Big YES

I can talk all day about the rising problem of obesity and give statistical figures, but it really won't matter unless I have a picture to prove how bad it really is.  With the help of Google, I searched for the perfect picture and found it on the CDC "Centers for Disease Control and Prevention" website.  They color coded each state based on the prevalence of obesity in the United States from 1985 to 2010.  I'll show the beginning, middle and end point to give you a glimpse of how obesity changed throughout the years.

To help you understand each map, I listed what each color represents:
  • White = No data
  • Light Blue = < 10%
  • Blue = 10-14%
  • Dark Blue = 15-18%
  • Yellow = 20-24%
  • Orange = 25-29%
  • Maroon = greater than or equal to 10%
1985:  To be fair, there wasn't a lot of data gathered from most of the states, but at least the ones that were recorded didn't reach higher than the 10-14% range.  Bicycle production near this time was 5.5 million (2)

1998: Almost all of the light blue states are now dark blue with some unfortunately breaking into a new category.  Near this time, 8.8 million units of bicycles were being produced, but by the year 2000, bicycle production fell to 1.1 million units (2).  Unfortunately, I couldn't find statistics up to 2010, but it is reasonable to assume that from this point in time, the trend shows that less bicycles were going to be produced and ridden.  With regards to physical activity, 54.6 percent of the nation reported that they did not meet the minimal level of recommended physical activity limit (3).

2010:  Every state official moved away from the blue zone and into the red zone.  It's important to note that in 2009, Colorado, a very bicycle friendly state, was the only state left in the dark blue zone with a prevalence from 15 to 19% (2).  The nations physical activity levels barely improved with 51.2 % of the population still failing to meet minimal levels of physical activity (3).

The problem with this question is that this is a problem that isn't easily fixed by anyone but the person who either developed a physical ailment, disease or simply chose to be inactive and lead an unhealthy lifestyle.  It is up to them to become motivated enough to seek help and change the nation from red to blue.

Kinesiological Approach To Bike Fit: Cleat Position

CLEAT POSITION:  There are four types of adjustments which can be made to a cleat.
Fore/ Aft:  FORE:  Positioning the cleat forward allows the ankle to move more freely, allowing for a smoother pedal stroke.  The trade-off is that this requires more ankle stability, calf strength and puts the rider at risk of developing quad dominance.AFT:  This position limits ankle motion.  This provides added stability to the ankle, allowing the calves to rest, but makes the rider prone to bouncy pedal strokes.  When switching from a forward cleat position to a rearward position, a lower saddle position is needed to compensate for decreased plantarflexion.Lateral/ Medial:  The goal is to spread weight evenly across the foot side-to-side.LATERAL:  Shifts weight towards the outside of the foot (small toe side).MEDIAL:  Shifts more weight onto the medial side of the foot (big toe side).  Limits the maximum amount of external rotation available before the heel strikes the crank arm.Rotation:EXTERNAL:  S…

How To Hold an Aero Position

There are climbs and then there are winds.  For many cyclists, riding into a strong wind can be more difficult than climbing, mostly because cyclists are required to reach a low aerodynamic position which can be uncomfortable, difficult or painful to hold.  Cyclists must demonstrate adequatehamstringandlower backflexibility to hold an aero position comfortably.  The flexibility needed to ride well in the wind can take time to develop, but with enough dedication and experience, anyone can become proficient at holding an aero position safely.  Here are some steps you can take to make holding an aero posture as comfortable as being on the hoods:

The worst thing a rider could do is force a low aero position and hope for the best.  With low back pain being one of the most frequent complaints among pros and recreational cyclist alike, the chances of long term pain- or injury-free riding are slim.  Develop the flexibility first, then shoot for the next lowest position yo…

Eagle Creek Park Cycling Grand Prix v2.0 - FIRST PLACE & FIRST PODIUM FINISH!

I can't even begin to describe how awesome it felt to have two dreams come true at once!  I always wondered what it would be like to be on the podium, but I never thought I had a chance at first place!

THE COURSE Below is a map of the course highlighted in blue.  It ran counterclockwise.  There were a few corners that stuck out to me.
Bottom right (corner #1):  This wasn't a very sharp corner, but the trees and brush made it difficult to see around it, so the group had a tendency to slow down and merge into a single line here.
Top right (corner #2):  This corner was very sharp, so oftentimes the group would merge into one or two pacelines, especially at higher speeds.
Top left (corner #3):  The inside half of this corner was covered by loose asphalt, so it wasn't an ideal or safe place to pass.  Pretty much everyone had to take a very awkward, wide line.  We could only fit about three abreast in this corner.
Bottom left (corner #4):  This was a very fast corner that led straigh…
