Sounds like what cyclists call intervall training. It is. If you add in the long rides. For example, Monday 1 min at 90% followed by 1 min walk (continue until you vomit); Tuesday 1 hour at race intensity, Wednesday rest, and so on. The long days can be thought of single intervals. I think it's different, more like what Lee said. Where a sprint maxes out the muscles. I don't max out mine much, meaning I could hammer up a hill faster but then I'd be pooped for many minutes and the ride would no longer be an enjoyable one. It gets very complicated. For example, there are fast twitch muscle fibers and slow twitch fibers. Doing sprints certainly causes the fast twitch fibers to grow but has a lesser effect on the slow twitch fibers. On the other hand, a series of stresses placed on the legs, for instance, certainly strengthens all the leg muscles. I used to do hill climbs. A hill ling enough that I ran out of breath and start in the lowest gets and ride to a certain place, coast back down to the bottom, shift up a gear and do the same thing. Theoretically this is a fast twitch exercise good for sprinters but it also improved my average speed for a 2 - 3 hour ride. With me that hasn't helped much. I get "natural climb training" every time I return from the valley which is once or twice a week. The last 10mi are up, down, up, down, a lot. My muscles are strong, the limitation seems to be that I simply run out of breath and general energy. I am not complaining since I am usually among the faster riders. Certainly not race material though. The thing is that there are really two equations that apply. One is VO2 max as Lee (I think) mentioned, and the other is strength. If you are Atlas (with the world on your shoulders) than the percentage of total strength being expended at, say 25 mph, going up hill is so low that you never even breath hard. But having said that if you are Atlas than you weigh more so you have more to carry up hill and thus must expend more energy. As I said, it is complicated and there probably is a reason that the hill-climbers are usually small light guys while sprinters are usually heaver with bigger muscles :-) My problem is that I can't convince anyone to join me for a ride unless I promise to keep it under 25mi. Those are often people who like to hammer it which I don't like to do. Back in the primitive days people used do essentially the same thing by training by distance, i.e., a quarter as hard as you can go followed by a quarter at a walk, and so on. As for your full tilt for hours, you really aren't doing that. What you are doing is riding at an energy output that you can maintain for some period. If you really were to exert 100% you might get a quarter of a mile before you collapsed. Yes, that is what I think as well. My limitation is more the breathing and I don't enjoy being totally out of breath for a long time. I was always an endurance kind of guy, never a good sprinter. Yes, endurance is generally determined by oxygen intake. Yes, runners and bicycle sprinters can perform at higher intensities but only for short times. A "miler" will run three laps at about maximum oxygen intake and the last lap he will accelerate and go into oxygen deficiency. Seen it but I was never good at that. Even in the army my better times were long-haul. 5km on the sports field, xx kilometer on "hikes" in full gear. With cycling it is similar. Yesterday was 43mi or 69km, to pick up a $1.75 item in the valley that I urgently need. About 30% of that ride was extra and just for fun. However, after this discussion I tried some muscle max-out phases and paid for that the last 10mi which are almost all uphill. Sure, you exceeded the effort that you can maintain for the entire ride. Yup. Or in other words my age begins to show. I see that sometimes where guys blast by me at high speed and then on the next long hill I pass them. I also see that sometimes guys blast by me at high speed and then go on out of sight :-) Oh yeah :-) -- cheers, John B. John, have you ever ridden up a long 7% hill at 25 mph? Every once in awhile I'll be in the mood to catch someone that ran away from the group and would do it. It really messes up the rest of your day. |
