WMT的骑行报告

好的骑行台可以更好的模拟自行车实际骑行的路感。当然，和实际的感觉还是不一样。优点缺点 binge兄已经说得很清楚了。
其实骑行台只是作为恶劣天气还有糟糕的环境下的一个替代品。
它的几大优势：
不用兴师动众，换上自锁鞋就能在家骑车。省去穿戴骑行装备的时间，也省去了洗衣服的麻烦
避免了交通事故的危险
没有吸收机动车尾气和灰尘的痛苦
可以专心地练习蹬踏，调整蹬踏的姿势
减少了保养自行车的频率
好的骑行台（某某同志买的上万的那种），能够模拟世界各地比赛线路，包括环法等经典赛段，让你在和世界高手过招的同时享受国外美景。也能按程序设定的训练计划进行训练，相当于请了一个专属教练。

明白了 就是更有针对性更专业的自行车训练器材 而健身单车偏向于全民健身 锻炼身体的范畴

22日，加班，未踩车。
算是休息日，明天计划踩50分钟。

总共50分钟，第40分钟抽筋，调节5分钟后完成后面的10分钟。
还没有装码表，无法准确知道速度，利用秒表计算速度再查表格计算功率：
平均功率 380w约合0.516马力
最大功率（一分钟）550w约合0.748马力

How Lance Armstrong Gets His Unusual Energy

Lance Armstrong's strength and endurance sometimes seem too extraordinary to be believed.
Armstrong, a six-time winner of the Tour de France bicycle race who next month will try for his seventh straight victory, can cover 32 miles in one hour of riding. In contrast, the average cyclist covers 16 miles; a top marathon runner can cover 21 miles on a bike.

Armstrong can ride up the mountains in France generating about 500 watts of power for 20 minutes, something a typical 25-year-old could do for only 30 seconds. A professional hockey player might last three minutes - and then throw up.

So how does he do it?

According to a scientist who studied Armstrong at regular intervals from 1992 to 1999, his prowess can be explained by a set of physiological changes that took place in his body over those seven years and that, in all probability, are continuing.

The changes are described in an article titled "Improved Muscular Efficiency Displayed as Tour de France Champion Matures" in the June issue of The Journal of Applied Physiology.

The scientist, Dr. Edward Coyle, director of the Human Performance Laboratory at the University of Texas, has studied cyclists for 25 years. He says they need large hearts and low levels of lactic acid - the byproduct of intense exercise - in their blood. Their efficiency, measured as how many watts of cycling power are generated for a given cycling input, needs to be high.

"Lance came to us when he was 20 years old, very early in his career," Dr. Coyle said. "He wanted to know what he could do to improve himself."

Armstrong, Dr. Coyle said, indeed had an exceptionally large heart and low lactic acid. "But his muscle efficiency was not very good," he said. "It came in at 21 percent. That first year two other athletes we studied were better."

Armstrong showed subsequent improvements until his career was stopped short in 1996 with a diagnosis of testicular cancer. Eight months after his treatment ended, he was back in the Austin laboratory.

"He wanted to know if anything was permanently wrong," Dr. Coyle said.

They took measurements and found nothing to stop him, except his own willingness to compete.

Armstrong did compete. "In the next two years his heart got even better, his lactic acid dropped further and, amazingly, his efficiency increased to 23 percent," Dr. Coyle said.

That may not sound like much, but it means that for the same level of oxygen consumption, Armstrong gets more power to the pedals. By taking off body weight, he was delivering 18 percent more power to his muscles.

There is only one way such efficiency could improve, Dr. Coyle said: more slow-twitch muscles, the type that do not burn out quickly and that are used in standing or walking. Fast-twitch muscles, which burn out fast, are used for sprinting and heavy lifting.

Rodent studies show that chronic stimulation to muscle tissue increases the amount of slow-twitch fibers, Dr. Coyle said. Armstrong appears to have increased the proportion of his slow-twitch muscles from 60 percent to 80 percent.

In bicycle races, slow-twitch fibers are up to twice as efficient as fast twitch.

网上查到这个
里面特别说明了兰斯可以在山地赛段以500瓦的功率骑行20分钟，而一个普通的25岁男子，才能坚持30秒左右。一个职业曲棍球运动员则可以坚持3分钟——然后嗝屁

一个成年人的马力大概在0.5马力，一马力等于735.49875 瓦，那么人的功率就是365w左右。
接近我测试的数值0.516马力。潜力待挖掘中……

如果这个能量用来发电，也能做蛮多事情了
由于大量出汗，我会当补充点电解质(如钾,钠)以及维生素，因为如果缺钾，会导致疲劳无法回复，心脏早搏(就是那种偶尔能感觉的那种咚的一下的停顿，不是长期的话，是无害的）。缺乏电解质，也会导致抽筋。
现在我一般一天骑车、一天游泳，如此往复。而且强度无法跟大王比，我的平均功率才100多W，当然，我的路线中有很多下坡，下坡的时候功率为0。

关注你们，骑行台在计划中。

和binge交流了一下，打算搞一个带心率 踏频 的码表先装着；配一箱子佳得乐或者氯化钾胶囊。
每天做好骑行记录，科学健身，科学训练
刚刚加班完毕，骑行时间0

先驱者开拓，后来者跟上！
