Stripped Down: Fill the Right

Over the past few years it has become very clear to me that from a physiological/adaptation perspective, if I am not dipping into the red zone (i.e – goin’ hard and raising the left) as the base of my training, I’mot being very efficient with my training

Strippped Down: Raise the Left

Missed part one? Read it here, first.
In general, I’ve found that it doesn’t seem as if there are any truly unique adaptations between the following raise the left types of rides. I try to keep it basic and believe that if one doesn’t go hard enough (i.e, going into the red zone) on a pretty regular basis they are likely missing out on some time efficient ways to achieve great physiological adaptations such as increased capillary density (additional pathways for blood to deliver oxygen) and increased mitochondria density (improved aerobic respiration for a given amount of delivered oxygen).

I've been racin' bikes competitively since 1991 – during that time, I've tried lots of crap when it comes to training and performance. For example, I've used a sledgehammer (25+hrs a week) - I've limited my HR below a certain level "building my base" and laying a foundation for the "hard stuff" to come. I've done 3 wks on 1wk off – 3 days on 1 day off. Macrocycles, microcycles – dun that!

Mitochondria: The Aerobic Engines
Thursday, 18 May 2006 08:00

Words by Kirk Willett
Aerobic metabolism provides nearly all the fuel we use to run our bodies. We can only live for a few minutes without the constant energy supply derived from aerobic respiration. It is why we have to breathe! Endurance sport performance places a premium on aerobic respiration and its ability to convert the energy in food into a form our body can use. It may not be intuitively obvious, but even maximal efforts as short as seventy-five seconds are primarily powered by aerobic energy systems (Gastin, 2001). As a result, a primary goal of any endurance sport training program involves the building of one’s aerobic engine. On the most basic level, mitochondria are our aerobic engines.

LA Can’t “Do It”
Why an Hour Record Attempt Might Not Happen
6/26/05 - Words and images by Kraig Willett
Despite the re-assurances of his current coach, and the empirical extrapolations of academia, I don’t think that LA can surpass the hour record held by Chris Boardman. Not that it matters, though, since LA is hanging up his wheels in a few weeks… What I’m about to present may seem like pretty tenuous evidence in support of a pretty bold claim (one that’s sure to draw the ire of a few people); however, relax folks, it’s just bike racin’ – and I’m just an abaqus-movin’-slide-rulin’-pencil-pushin’-not-much-smarter-than-a-box-of-rocks-dork!
