機(ji)(ji)械跑(pao)步(bu)(bu)機(ji)(ji)的(de)傳(chuan)動(dong)系統是(shi)由一(yi)個傳(chuan)送帶(dai)(dai)(dai)套子，里(li)面兩(liang)(liang)端兩(liang)(liang)根固(gu)定軸(zhou)把(ba)傳(chuan)送帶(dai)(dai)(dai)拉(la)緊，有(you)一(yi)個軸(zhou)和(he)滾軸(zhou)連接，一(yi)個可調式開關和(he)一(yi)個固(gu)定架(jia)構成，主要是(shi)依靠(kao)跑(pao)步(bu)(bu)者腳與跑(pao)步(bu)(bu)帶(dai)(dai)(dai)的(de)摩擦力帶(dai)(dai)(dai)動(dong)來運行(xing)的(de)；電(dian)(dian)動(dong)跑(pao)步(bu)(bu)機(ji)(ji)是(shi)依靠(kao)電(dian)(dian)機(ji)(ji)帶(dai)(dai)(dai)動(dong)跑(pao)步(bu)(bu)帶(dai)(dai)(dai)運行(xing)，通過(guo)變(bian)頻器(qi)來控(kong)制馬達(da)轉速(su)(su)實現(xian)調節跑(pao)步(bu)(bu)時的(de)速(su)(su)度變(bian)化，變(bian)頻器(qi)的(de)控(kong)制，就是(shi)將傳(chuan)感器(qi)的(de)信(xin)號進行(xing)處理（電(dian)(dian)壓轉換），然后計數，可以得到速(su)(su)度。從這一(yi)點來看，機(ji)(ji)械跑(pao)步(bu)(bu)機(ji)(ji)要比電(dian)(dian)動(dong)跑(pao)步(bu)(bu)機(ji)(ji)費力許(xu)多，不方便所(suo)以也不容易堅持。

機(ji)械跑(pao)(pao)(pao)步(bu)(bu)機(ji)可以說是一種(zhong)主動(dong)(dong)(dong)(dong)(dong)跑(pao)(pao)(pao)步(bu)(bu)的(de)(de)(de)器(qi)械。它的(de)(de)(de)動(dong)(dong)(dong)(dong)(dong)力來源是使用(yong)者(zhe)通過自身臂部(bu)(bu)(bu)、膝部(bu)(bu)(bu)、踝關節(jie)及(ji)相關肌(ji)肉產(chan)生(sheng)向后的(de)(de)(de)推力，推動(dong)(dong)(dong)(dong)(dong)跑(pao)(pao)(pao)步(bu)(bu)機(ji)產(chan)生(sheng)運(yun)動(dong)(dong)(dong)(dong)(dong)。使用(yong)這(zhe)(zhe)種(zhong)方(fang)式在(zai)跑(pao)(pao)(pao)步(bu)(bu)機(ji)鍛煉，產(chan)生(sheng)的(de)(de)(de)運(yun)動(dong)(dong)(dong)(dong)(dong)傷(shang)害(hai)卻比在(zai)大(da)自然中跑(pao)(pao)(pao)步(bu)(bu)產(chan)生(sheng)的(de)(de)(de)運(yun)動(dong)(dong)(dong)(dong)(dong)傷(shang)害(hai)要(yao)大(da)數(shu)倍。運(yun)動(dong)(dong)(dong)(dong)(dong)醫學專家稱：馬路上跑(pao)(pao)(pao)步(bu)(bu)，每(mei)跑(pao)(pao)(pao)一千米(mi)，每(mei)只腳(jiao)(jiao)(jiao)就得撞擊(ji)地面約1000次左右，腳(jiao)(jiao)(jiao)踝部(bu)(bu)(bu)、膝部(bu)(bu)(bu)和臀(tun)部(bu)(bu)(bu)都(dou)受(shou)到震(zhen)蕩，容易導致肌(ji)肉扭(niu)(niu)傷(shang)或韌帶拉(la)傷(shang)；而在(zai)機(ji)械跑(pao)(pao)(pao)步(bu)(bu)機(ji)上跑(pao)(pao)(pao)步(bu)(bu)，人體除自身重量(liang)產(chan)生(sheng)的(de)(de)(de)震(zhen)蕩外(wai)(wai)，腳(jiao)(jiao)(jiao)踝部(bu)(bu)(bu)、膝部(bu)(bu)(bu)和臀(tun)部(bu)(bu)(bu)，特(te)別是肌(ji)腱，還要(yao)承(cheng)擔(dan)額外(wai)(wai)向后的(de)(de)(de)扭(niu)(niu)力來確保跑(pao)(pao)(pao)帶向后運(yun)動(dong)(dong)(dong)(dong)(dong)，這(zhe)(zhe)種(zhong)額外(wai)(wai)的(de)(de)(de)扭(niu)(niu)力就是產(chan)生(sheng)運(yun)動(dong)(dong)(dong)(dong)(dong)傷(shang)害(hai)的(de)(de)(de)根源。

而(er)由(you)于電(dian)(dian)動(dong)跑(pao)步機(ji)是(shi)一(yi)種主動(dong)與被(bei)動(dong)相結合的(de)(de)運(yun)動(dong)方式，在電(dian)(dian)動(dong)跑(pao)步機(ji)上的(de)(de)跑(pao)或走都會比(bi)普通的(de)(de)人(ren)省去了一(yi)個蹬(deng)腿伸的(de)(de)動(dong)作。這(zhe)樣的(de)(de)話好處就是(shi)使得每(mei)一(yi)個人(ren)在電(dian)(dian)動(dong)跑(pao)步機(ji)上面跑(pao)步會感到十(shi)分(fen)的(de)(de)輕(qing)松、暢快。

除此之外，機械跑(pao)步機的跑(pao)板跑(pao)帶材質都很(hen)一般，起不(bu)到保護關(guan)節的作用，減震設計也很(hen)少，在運(yun)動(dong)(dong)(dong)者主動(dong)(dong)(dong)行走或做蹬踏動(dong)(dong)(dong)作的時候容易對運(yun)動(dong)(dong)(dong)者的膝(xi)關(guan)節和踝關(guan)節造成損傷；電動(dong)(dong)(dong)跑(pao)步機則增(zeng)加(jia)了(le)(le)很(hen)多的科(ke)(ke)技含量(liang)的技術，使訓練效果更加(jia)科(ke)(ke)學，采用了(le)(le)專利避震系(xi)統，對膝(xi)關(guan)節和踝關(guan)節的沖擊(ji)力小，降低發(fa)生運(yun)動(dong)(dong)(dong)傷害的可能性。

而機(ji)(ji)械跑(pao)步機(ji)(ji)通過(guo)人體帶動(dong)跑(pao)帶運行，表面上(shang)看起來似乎能(neng)消(xiao)耗更多(duo)的(de)能(neng)量，但(dan)是(shi)由于跑(pao)步過(guo)程(cheng)中(zhong)為了(le)使(shi)(shi)跑(pao)帶能(neng)向(xiang)后(hou)運轉而故意向(xiang)后(hou)產生的(de)扭力過(guo)度集(ji)中(zhong)在韌帶、關節等幾個關鍵受力部(bu)(bu)位，這種(zhong)(zhong)(zhong)扭力更容易使(shi)(shi)受力部(bu)(bu)位肌腱組織產生慢性(xing)疲(pi)勞，從而打(da)(da)破(po)這部(bu)(bu)分組織的(de)局部(bu)(bu)平衡、損傷其健康。把運動(dong)變(bian)成一種(zhong)(zhong)(zhong)疲(pi)勞、是(shi)打(da)(da)擊人們(men)產生運動(dong)興趣的(de)克(ke)星，也(ye)是(shi)大部(bu)(bu)分運動(dong)者運動(dong)失(shi)敗的(de)主要原因。越(yue)來越(yue)多(duo)的(de)傳統跑(pao)步機(ji)(ji)使(shi)(shi)用者，發現(xian)自己越(yue)是(shi)認真(zhen)鍛煉，腿部(bu)(bu)越(yue)跑(pao)越(yue)粗、而關節部(bu)(bu)位越(yue)練越(yue)沒有力氣就不足為奇了(le)。這種(zhong)(zhong)(zhong)疲(pi)勞感和健身副作用都會嚴重(zhong)打(da)(da)擊你健身的(de)積極性(xing)。

機(ji)械(xie)跑步(bu)(bu)機(ji)屬于(yu)90年代的(de)(de)(de)(de)(de)運(yun)動(dong)產品，是較(jiao)早一(yi)代的(de)(de)(de)(de)(de)跑步(bu)(bu)機(ji)，隨著跑步(bu)(bu)機(ji)的(de)(de)(de)(de)(de)更(geng)新(xin)換(huan)代，逐漸被電(dian)動(dong)跑步(bu)(bu)機(ji)所取代，現在已基(ji)本淡出市場。電(dian)動(dong)跑步(bu)(bu)機(ji)的(de)(de)(de)(de)(de)研發與生產是建立在機(ji)械(xie)跑步(bu)(bu)機(ji)基(ji)礎上的(de)(de)(de)(de)(de)，也可以將它說成機(ji)械(xie)跑步(bu)(bu)機(ji)的(de)(de)(de)(de)(de)升級(ji)版，

機(ji)械(xie)式的(de)(de)(de)跑(pao)(pao)(pao)步(bu)(bu)機(ji)只需要(yao)幾百元錢(qian)，電動跑(pao)(pao)(pao)步(bu)(bu)機(ji)最(zui)便宜的(de)(de)(de)也需要(yao)2000元左右。價(jia)格相差好(hao)幾倍，但(dan)是(shi)這(zhe)跟跑(pao)(pao)(pao)步(bu)(bu)機(ji)的(de)(de)(de)驅動力、基本構造和功(gong)能(neng)(neng)及舒適度都是(shi)有關系(xi)的(de)(de)(de)。電動跑(pao)(pao)(pao)步(bu)(bu)機(ji)的(de)(de)(de)電機(ji)、跑(pao)(pao)(pao)板、跑(pao)(pao)(pao)帶、心率測試等部件與機(ji)械(xie)跑(pao)(pao)(pao)步(bu)(bu)機(ji)的(de)(de)(de)跑(pao)(pao)(pao)帶、滾軸差異很(hen)大。電跑(pao)(pao)(pao)還有不(bu)同阻力、坡度的(de)(de)(de)調節，跑(pao)(pao)(pao)步(bu)(bu)公(gong)里數(shu)、消耗能(neng)(neng)量、心率等數(shu)據(ju)的(de)(de)(de)顯示，機(ji)械(xie)跑(pao)(pao)(pao)步(bu)(bu)機(ji)是(shi)無法達(da)到的(de)(de)(de)。俗話(hua)說，一分價(jia)錢(qian)一分貨，在(zai)這(zhe)里再合適不(bu)過了。
