Today was spin-up day on the trainer. Spin-ups are low intensity intervals that are designed to fire up the neuromuscular system, through short rounds of high RPM spinning. I began with 10-minutes of warm-up...basically to get the blood flowing, and wake up the nervous system. Once the warm-up was over, it was time to get spinning. The workout consisted of 10 rounds of 30-second 110 RPM spins, followed by 2 1/2 minutes of low- to moderate-intensity pedaling. The workout, if done correctly, should not cause the heart rate to become too elevated, as fatigue is not the desired outcome. What is the desired outcome you ask? Improving the neuromuscular pathways. You see, when fatigue sets in it is difficult to recruit fast twitch muscle fibers...you know, the ones that are used for bursts of power, like sprinting, jumping, and pedaling really, really fast. By limiting the amount of fatigue within the muscle, the neuromuscular pathways can actually be trained to perform more efficiently, ultimately allowing for longer periods of sustained, explosive power output.
So that was my workout today. Tomorrow...time to hit the weights!
