Catching up on my reading this weekend and ran across this in the Feb issue of the Journal of Strength and Conditioning Research. Old forum participant Jennifer Klau was published!

Congrats to her.

Interesting to note some additional statements from the concluding paragraphs.... (They're not talking about resistance machines and stuff you do rolling around on a ball or balancing on a wobble board.)

"Although the body of evidence is limited, the autors recommend replacing a portion of an athletes endurance training volume with explosive resistance training to increase TT performance and maximal power output and to minimize the risk of fatigue from an overwhelming total training volume."

"Coaches and researchers designing future studies should use this systematic review as a starting point to design protocols that implement resistance training programs that emphasize heavier weight with lower repetitions, Olympic style lifts, and plyometrics to increase force production and improve performance."

Abstract
Highly trained cyclists may be hesitant to incorporate resistance training (RT) with their endurance training (ET) because of the mixed data regarding concurrent RT and ET (CT). The purpose of this review was to search the scientific body of literature for randomized controlled trials (RCTs) of CT on road cycling performance for highly trained cyclists. Key words (including cycling and strength training) were used to search relevant databases through September 2009 for literature related to CT. Randomized controlled trials were included if they scored > or =5 on the Physiotherapy Evidence Database scale. Five studies met the inclusion criteria: highly trained road cyclists (>7 h.wk or > 150 km.wk, with at least 6 months of training), outcome measure was cycling performance (time trial or time to exhaustion), and RT performed off-bike. Two of the 5 studies found no improvement in performance with CT, but these studies added RT on top of the athletes' existing ET. The 3 studies with improved cycling performance replaced a portion of the athletes' ET with RT, and 2 of the 3 studies included high-intensity explosive-type resistance exercises. Despite the limited research on CT for highly trained cyclists, it is likely that replacing a portion of a cyclist's ET with RT will result in improved time trial performance and maximal power.

Thanks for posting this, Todd. I've let my NSCA membership lapse so I would've missed it. Perhaps time for a re-think.

For the first time ever, this winter I fancy I must've done more strength work than endurance......with more of the "explosive" stuff (more of a "pop" at my age, I guess). The few races I've done, my times have been a bit better with much less of a struggle (I didn't feel like I was wearing diver's boots in my run off the bike in my duathlon)

I think I've targeted my glutes and hammies much more with dead lifts and my kettlebells and it's given me more snap. The daughter has been doing the same and yesterday did a 1/2 marathon and her mile pace was well below 8 minutes for the first time.....again with less pure "endurance" training.

The evidence for cycling is pretty mixed. Notice they don't give any kind of weight training a full endorsement.

But the positive effects of this type of training is pretty well documented for runners. I'm guessing the benefits your daughter is seeing are real.

JFK has been in WonderWoman mode- research girl, mom, taking care of all of the business...! DOCTORATE!!!!! I am so proud of her! She just dove in. I hope anyone who went to WSSC this year got to take her 'guest' lecture...
