在長時間的運動下，脂肪會為身體帶來能源，支撐身體肌肉所需。馬拉松全程為42.195km，脂肪所提供的能源協助絕對不可或缺。98Please respect copyright.ＰＥＮＡＮＡ6MXOfjoErK

在這個前題下，為何為數不少的瘦削運動員都可以足夠應付長距離的馬拉松呢?98Please respect copyright.ＰＥＮＡＮＡymOAhaKlxm

（圖2）在此，我們嘗試一下利用數學角度，以卡路里的消耗量探討這一個問題。98Please respect copyright.ＰＥＮＡＮＡqNHAZALjgC
98Please respect copyright.ＰＥＮＡＮＡHHKSqtxaJ9
98Please respect copyright.ＰＥＮＡＮＡTEDAuHGci6
有研究確認(Ref1,2)，身體消耗的卡路里是與行走總距離有關，而非行走速度。98Please respect copyright.ＰＥＮＡＮＡvwIGIURcT7
98Please respect copyright.ＰＥＮＡＮＡEe7jMYyFNK
他們最終得出的公式為每1kg行走1km平地就會消耗1卡路里。98Please respect copyright.ＰＥＮＡＮＡ5ZJG9aRRKI

如果我們假設1個70kg的男人跑一場馬拉松，所消耗的總卡路里就會為98Please respect copyright.ＰＥＮＡＮＡnvdXipbWip

70kg x 42.195km=98Please respect copyright.ＰＥＮＡＮＡgbaK02uuDb

（圖3）身體的脂肪每克約可以提供9kcal，如果我們用上最極端的例子，負責儲存能源的體脂只佔身體重量2% (正常為10-32%)的話，所提供得到的能源就會是98Please respect copyright.ＰＥＮＡＮＡdBl7NLXIcV
98Please respect copyright.ＰＥＮＡＮＡQjxAon7Rw9
70kg x 1000 x 2% x 998Please respect copyright.ＰＥＮＡＮＡK6kJ8A2zK6
=12600 kcal98Please respect copyright.ＰＥＮＡＮＡy1hmjwtNoC
98Please respect copyright.ＰＥＮＡＮＡJ4VBxORgjc
98Please respect copyright.ＰＥＮＡＮＡkXWMG8w2Nm
而基於每場馬拉松所消耗的卡路里僅為2950kcal關係，12600/2950 = 4.27，單憑身體脂肪所提供的能源，就足以應付4場馬拉松!98Please respect copyright.ＰＥＮＡＮＡVdybCqEvSj

這個跑4次馬拉松的結果是以極低（儲存能量用的體脂2%）這個極端例子作計算，可以推算得到正常人的話絕對是遊刃有餘跑1場馬拉松；98Please respect copyright.ＰＥＮＡＮＡYd5CDaFwGF
98Please respect copyright.ＰＥＮＡＮＡktK3y97wFM
此計算方式是假設整場馬拉松是平地鋪設，沒有高低鈄坡。98Please respect copyright.ＰＥＮＡＮＡ8qtTaoyuTu

（圖4）不過，魔鬼在細節，這集反應熱烈的話，下一集將會探討這個計算方式的漏洞以及馬拉松選手經常會遇到所謂Hit The Wall的問題。98Please respect copyright.ＰＥＮＡＮＡFgBXqsNOI9
