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。67Please respect copyright.ＰＥＮＡＮＡo4ibX6u5iK

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。67Please respect copyright.ＰＥＮＡＮＡaaaIICPAVY

（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?67Please respect copyright.ＰＥＮＡＮＡvPg6j5tH8a

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。67Please respect copyright.ＰＥＮＡＮＡ9VR8mNMPKg

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)。67Please respect copyright.ＰＥＮＡＮＡ1HWUV7nD5Y

（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。67Please respect copyright.ＰＥＮＡＮＡMXubZKRrRs

每1kg每1km就會消耗1卡路里，只適用於跑步之上。67Please respect copyright.ＰＥＮＡＮＡLCGVT6rUEw

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。67Please respect copyright.ＰＥＮＡＮＡpzRLQotJyB
67Please respect copyright.ＰＥＮＡＮＡEcNPKZztF6
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。67Please respect copyright.ＰＥＮＡＮＡj0naLe5xOi

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。67Please respect copyright.ＰＥＮＡＮＡdaKfNHGzN9

（圖3）究竟身體能夠提供得到幾多卡路里予運動上?67Please respect copyright.ＰＥＮＡＮＡEEHNfubX8B

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?67Please respect copyright.ＰＥＮＡＮＡHVJxirWUy1

好大部份的原因，均歸咎於名為HIT THE WALL的現象，下篇再續。67Please respect copyright.ＰＥＮＡＮＡT9WZQcghbd
