1. 香吉士加入BMC 之後，氣色真好





2. 乳酸的謬誤

Colorado State University Human Performance Research Lab 教授Matthew Hickey 對於人體中所產生的的乳酸表示：The bottom line is, no. There is no lactic acid in human beings.

先上點理化課：討論酸鹼鹽在溶液中的作用，先要有共軛酸鹼對的觀念

乳酸/乳酸鹽所形成的緩衝pH 3.87，遠低於人體中的緩衝pH 7.2-7.4...所以你要是催到產生乳酸滿檔，就要緊急送醫了


那...催到昇天，腿好像快燒起來是怎麼回事？

人體的能量系統中，讓肌肉產生收縮時，會產生乳酸與氫離子(以前的運動生理學家單測乳酸值，讓乳酸蒙了不白之冤)，這些是我們身體可以回收再製成ATP

當操到欲生欲死，咬碎銀牙時...身體無法完全代謝能量系統產生的乳酸與氫離子


於是生不如死...

因此，提升最大攝氧量(很難！再怎樣也不可能超越狗)並有效的利用(操就有)，加上鍛鍊自己在乳酸閾時忍受度以及功率輸出...是現在耐力運動訓練的中心
