Ric,
you missed the study by Hickson. In that study:
8 experienced cyclists strength trained for 3 days per week for a 10 week period. This was added to their regular endurance routines. Strength training included 5x5 squats, 3x5 squats, 3x5 knee flexion, and 3x25 calf raises with relatively heavy resistance increasing throughout the program as strength improved.
Time to fatigue when cycling at 80% VO2 max increased by 20% (from 71 to 85 minutes).
So, saying that "there are *no* studies showing a positive effect using trained cyclists and weights" is absolutely 100% wrong. You need to not make these blanket statements and just realize the fact that there is a benefit for certain, not all, cyclists to adopt a strength training routine (either in the gym, on the bike, or both) at the appropriate time of their training.
On a similar note, since running is an endurance sport but still different from cycling of course, there have been similar studies done on strength training and endurance performance & running economy. One such study examined hill running as a means to improve running economy. Before I go on, I'm not saying that there is a direct relationship between improvements in running economy by running hills and an improvement in cycling performance by cycling on hills. The point that the researchers made in this study was that the hill running, while building strength, simultaneously trained the aerobic system. At the end of the study, they found that running economy improved by 1-4% - they used elite runners in the study.
This hill running that the elite runners participated in improved their economy because they learned to run in a fashion that expended the least amount of energy. After all, running consumes enough energy, so when running hills, the last thing we want to do is waste energy.
In cycling, the same holds true. When we climb, who wants to waste energy with unecessary movements? Resistance training (i.e. hill training) on-the-bike not only improves our cardiovascular system and makes us stronger because of the slightly larger forces we have to apply to overcome the force of gravity, but also can improve our economy by minimzing wasted upper body movements and limiting "mashing" on the pedals (both are activities that waste energy in the long run).
jagrazor, can you point us in the right direction to find the two studies you produced on this topic? I'd like to read them ๐.
Thanks!
