I've been doing some intervals lately on my computrainer which hit L7, L6, and L5 all within the same interval. The way it works is I set up the computrainer .erg file to start the interval at L7 (600watts), then rapidly decrease wattage over the next minute to L6 (360 watts), and ramp down over the next two minutes to L5 and finaly to my FTP wattage. In practice the interval starts out with an all-out neuro muscular effort and then hold on for dear life to try and finish the effort. My thinking is that I can get the L7 neuromuscular adaptation with the all out start, the L6 training during the next minute or so while AWC is used up, and L5 when I hit VO2Max over the last two minutes or so. In other words I just go all out for 4 minutes, and I'm packing all my high-intensity training into a single 1 hour session. The efforts are obviously hard as hell, and I'm still trying to get the wattage dialed on the computrainer so I can actually complete the interval. Does anyone else do workouts similar to this? Opinions on the effectiveness of this type of workout?
