this one or this discussion http://www.cyclingforums.com/t38904.html ?
Quoted post said:
A: it places high importance on maintaining upper body strength right through the year via weight training, whilst explaining to focus on lower body training only in the off-season, yet to focus on power output increases by sport specific power training (during the season) on the bike. (sets of power sprints etc with 5 min breaks - an exercise that would obviously invoke hypertrophy)
i'm not sure whether CCs book is aimed at recreational riders or racing cyclists, as there'd be a difference in the recommendations (recreational = ok to weight training, endurance racer = not).
additionally, there's *nowhere* i've said not to do power training on the bike, in fact i'm well known for having the riders i coach doing intervals throughout the year. i think you're confusing power with strength, which are different metrics and mean totally different things.
Strength is defined as the maximum force or tension that can be generated by a muscle or group of muscles
Power (at least as relating to cycling as there's several definitions depending on the topic, although they can all be used to work out each other) is the sum of all the resistive forces that must be overcome to travel at a given velocity under the conditions encountered

B: it confirmed that the diet practices and muscle requirements I was following, including the concepts of pre/during/post ride nutrition was not just my imagination, and that atrophy will occur by doing the wrong exercise with the wrong diet.
i haven't discussed diet (i discussed energy expenditure). if i'm not mistaken, CC recommends the same type of diet as i do (i.e. a moderately high carbohydrate based diet) -- this is the standard as recommended by e.g. ACSM

C: Whilst not stating exactly it did infer that weight training will certainly increase strength by conditioning the muscle, without significant hypertrophy occurring. This would explain the hyperbolic gains of a newbie doing weight training : power output increases rapidly in the first sessions - someone battling to bench 60kg on their first day may do it easily within a week or 2........ without any significant mass gains ........ yet to get to 70kg can take far more work, as the muscle just hasn't got the power output, and therefore needs to condition & grow to do it. It explains that plateau everyone reaches where more work is required for less gains ? And it's not just the case for newbies. I know that the next time I hit the gym, within 2 sessions, the muscle will feel firmer, and a flex will feel tighter. But I won't have gained any significant mass. How does one explain this ? Is it just that your body has been reminded that the muscle is there and that the physical control of that muscle has increased just by triggering it's use ?? I'll leave that one for you (couldn't find concrete statement to confirm the general inferences of the book)
there's two adaptations that occur (or occur for this discussion).
1) there's neuromuscular adaptations - these take place at the specific joint angle and velocity at which they're trained and don't transfer to a different exercise modality or angle and velocity. as you point out in strength training; there's an initial large increase in strength (for e.g.) with a bench press. Over the first ~8 weeks of regular training, the amount of weight you maybe able to lift can increase ~100%. these are neuro adaptations. the classis example is to then test the subject using the same muscles involved as in (e.g.) bench press, but doing an isometric contraction. results show that while there's a huge (~100%) increase in bench press weight, isometric contraction strength may have only increased 1 or 2 %, which is likely to be inline with increases in muscle cross sectional area
2) increases in muscle cross sectional area (hypertrophy) maybe transferable to different modalities. however, in the case of cycling you then have more weight to lug up a hill (not good), the increased strength only affects peak sprint power, it has no affect on aerobic performance (except in untrained riders)

D: it was written by a guy called Chris Carmichael, who trains this guy called Lance Armstrong. :p
i don't recall if CC has a degree in sports science/exercise physiology or related subjects (that maybe of less importance for coaching), however, i'm currently writing a review paper for a peer reviewed scientific journal on this topic
Quoted post said:
I don't know if I've read this book backwards or not, but it seems pretty clear in it's recommendations that power training (total body) is very beneficial. It also made the obvious statement that climbers and sprinters will have different training objectives, and body shapes.
again, just to clarify, i haven't said anywhere that it's not good or you shouldn't do hard bike work -- you should. i stated that strength training (which is different to power) isn't beneficial to cycling (except in certain circumstances, e.g., 200-m track sprinter, kilo rider, someone with a functional disability, etc)
Quoted post said:
I'll be re-reading more of it, to try and back up these contradicting theories. What I do get from this book does indicate that the power-to-weight ratio is obviously different depending on what you want to achieve. Focus on power if you want to blow by the smart@ss in the sprints of your bunch ride (including upper body strength). Focus on attaining a compromised strength/endurance whilst keeping mass down if you want to excel in the hills. [/B]
under standardised conditions and ignoring tactics, for any cyclist who wants to be better than another, then they will need more power over whatever duration is the critical aspect
