But, Why need to train single leg technique if you can use two legs power in pedalling...
I can not figure out what is the advantage... please explain further... ;D
I'll just try to put into simpler words... I'm not saying single-leg training should replace normal cycling, just that if you're serious about improving, it could be one of the numerous training techniques you could employ in your program. For discussions sake, let's focus on endurance training, not the sprints and maarat like climbs.
If you cycle on a relatively flat piece of road, you will be limited by your VO2max, that is the maximum capacity of your body to deliver oxygen to the working muscles. Say you have a VO2max of 100 (just an arbitrary number), that would mean a VO2 of 50 per leg (discounting all oxygen that the other parts of your body uses). And as endurance performance goes, there are 2 kinds of adaptations, central and peripheral. Central adaptations are those that happen in the heart, lungs, and blood (in other words, they affect the whole body). Peripheral adaptations are what happen in the working muscle (increased capacity of the muscle to take out oxygen from the blood, increased lactate use, etc).
So if you cycle at a level of 50 VO2 for each leg (since your limit is 100) the muscles in your leg will only adapt to the level it is currently doing.
With single-leg training, you can push your VO2 to probably around 80, not 100 but definitely more than the 50 per leg earlier. But all this effort is going into 1-leg. So theoretically, the skeletal muscle (peripheral) adaptations will be higher in the working leg, thereby increasing the muscle's capacity to do work.
Is that clearer now?
