上一篇提及身體消耗的卡路里是與步行總距離有關，其正確用字應為跑步總距離，非步行總距離。503Please respect copyright.ＰＥＮＡＮＡ8fWVkvKRWr

最終所得出的公式應為每1kg跑步1km就會消耗1卡路里，而非每1kg步行1km就會消耗1卡路里。503Please respect copyright.ＰＥＮＡＮＡHK0tpaG5Vk

（圖2）之於公式為每1kg跑步1km就會消耗1卡路里，究竟是如何得出來的呢?503Please respect copyright.ＰＥＮＡＮＡZUymcPXSa1

這是根據跑者真實實驗數據所得，跑速越快的話，能量消耗亦會越大，而且兩者的關係亦成直線相關趨勢。503Please respect copyright.ＰＥＮＡＮＡt2vUgsAZDd

如果我們將Y-axis的單位同X-axis的單位相除，就可以推算出一個kcal/kg/km的常數(constant)。503Please respect copyright.ＰＥＮＡＮＡonZuNw4hK5

（圖3）上一篇因錯誤用字的關係，做成了假設體重一樣，跑步1km與行路1km消耗的卡路里均會一樣的假象，這裡特別在這方面略微深入講解一下。503Please respect copyright.ＰＥＮＡＮＡGF2SECLU1t

每1kg每1km就會消耗1卡路里，只適用於跑步之上。503Please respect copyright.ＰＥＮＡＮＡpxAdXIndKC

從左面的圖中得知，當步速高過10km/hr的時候，能量消耗與步速才會成直線相關趨勢，每1kg每1km就會消耗1卡路里才可套用。503Please respect copyright.ＰＥＮＡＮＡaOcxgBsY0X
503Please respect copyright.ＰＥＮＡＮＡjCVkDmzw0p
而步速低過10km/hr的時候，能量消耗與步速再也不成直線相關趨勢，每1kg每1km就會消耗1卡路里的定律亦唔能夠得以套用。503Please respect copyright.ＰＥＮＡＮＡy6mFxHWykz

雖然香港人節奏急速，但以10km/hr的速度「行路」就應該不會太可行。503Please respect copyright.ＰＥＮＡＮＡ3TH4Bd3tZI

如圖中所見，駭眼數字好足夠應付馬拉松的卡路里消耗，那麼為何這麼多人中途會無法支持下去呢?503Please respect copyright.ＰＥＮＡＮＡap1ugHbC8d

好大部份的原因，均歸咎於名為HIT THE WALL的現象，下篇再續。503Please respect copyright.ＰＥＮＡＮＡ4XFMPquKjf
