運動地(di)板特點：

舒適性問題

專業的(de)PVC 塑膠運動地板的(de)表面(mian)能在受到撞擊時(shi)，適度變形(xing)，如同一(yi)個(ge)內有空(kong)氣的(de)密(mi)封床墊，當您在摔跤或滑倒的(de)時(shi)候(hou)，密(mi)閉(bi)泡沫(mo)背(bei)層技術提供的(de)緩沖(chong)作用能大(da)限度的(de)減少運動傷害。

震顫的(de)問題

震(zhen)顫是(shi)指地(di)板(ban)受(shou)撞擊而變(bian)形的(de)范(fan)圍，這(zhe)個震(zhen)顫范(fan)圍越大越容易引起(qi)骨(gu)折。震(zhen)顫有兩種：點震(zhen)顫和區(qu)域(yu)震(zhen)顫。

振動吸收(shou)問題

人在(zai)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)時(shi)形(xing)(xing)成的沖(chong)(chong)量(liang)作用在(zai)PVC塑(su)膠運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)地(di)板(ban)(ban)表(biao)面(mian)(mian)上(shang)會產生(sheng)震動(dong)(dong)(dong)(dong)(dong)(dong)(dong)，地(di)板(ban)(ban)的結構必須具備(bei)震動(dong)(dong)(dong)(dong)(dong)(dong)(dong)吸收的功能(neng)，也就是指地(di)板(ban)(ban)應具有吸收撞擊(ji)(ji)能(neng)量(liang)的性能(neng)，運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)員(yuan)在(zai)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)地(di)板(ban)(ban)上(shang)所(suo)(suo)受到(dao)的反撞擊(ji)(ji)力相比(bi)在(zai)硬地(di)面(mian)(mian)上(shang)，如在(zai)水泥(ni)地(di)面(mian)(mian)上(shang)的運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)要小的多。即：運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)員(yuan)跳起(qi)回(hui)落到(dao)地(di)板(ban)(ban)時(shi)，起(qi)碼(ma)要有53%以(yi)上(shang)的沖(chong)(chong)擊(ji)(ji)量(liang)被地(di)板(ban)(ban)所(suo)(suo)吸收，從而(er)起(qi)到(dao)保護運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)員(yuan)的踝關節、半月板(ban)(ban)、脊髓、大腦的作用，使人在(zai)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)時(shi)不(bu)致受到(dao)傷害。其保護功能(neng)也考慮了一個人在(zai)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)地(di)板(ban)(ban)上(shang)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)(dong)時(shi)不(bu)能(neng)影(ying)響相鄰(lin)人員(yuan)。這也就是德國DIN標(biao)準中所(suo)(suo)描(miao)述的震動(dong)(dong)(dong)(dong)(dong)(dong)(dong)吸收、震動(dong)(dong)(dong)(dong)(dong)(dong)(dong)變形(xing)(xing)與延伸變形(xing)(xing)的概念。

摩擦系數問題

研究表明12%的籃球(qiu)運(yun)(yun)動(dong)員(yuan)受傷發生在(zai)原地(di)的轉(zhuan)(zhuan)動(dong)過程中(zhong)。運(yun)(yun)動(dong)地(di)板的摩(mo)(mo)(mo)擦(ca)系(xi)數(shu)說明了地(di)板是(shi)(shi)否摩(mo)(mo)(mo)擦(ca)力(li)太(tai)強（這會(hui)降低(di)轉(zhuan)(zhuan)動(dong)的靈(ling)活性(xing)(xing)）或是(shi)(shi)太(tai)滑(hua)（這會(hui)增加滑(hua)倒的風險）。考(kao)慮到運(yun)(yun)動(dong)員(yuan)的活動(dong)能(neng)力(li)和安全，摩(mo)(mo)(mo)擦(ca)系(xi)數(shu)在(zai) 0.4-0.7 之間(jian)應(ying)為(wei)佳值。 PVC塑(su)(su)膠運(yun)(yun)動(dong)地(di)板的摩(mo)(mo)(mo)擦(ca)系(xi)數(shu)一(yi)般均保(bao)持在(zai)這個系(xi)數(shu)之間(jian)，專業性(xing)(xing)萬奧PVC塑(su)(su)膠運(yun)(yun)動(dong)地(di)板的摩(mo)(mo)(mo)擦(ca)系(xi)數(shu)為(wei)0.57，它具有充足且(qie)適度(du)的摩(mo)(mo)(mo)擦(ca)力(li)，能(neng)保(bao)證運(yun)(yun)動(dong)的穩定性(xing)(xing)，同(tong)時(shi)能(neng)在(zai)各個移動(dong)方(fang)向上保(bao)持摩(mo)(mo)(mo)擦(ca)性(xing)(xing)能(neng)的一(yi)貫性(xing)(xing)及(ji)規律(lv)性(xing)(xing)，以保(bao)證靈(ling)活移動(dong)和原地(di)轉(zhuan)(zhuan)動(dong)不受任(ren)何阻礙。

球回彈(dan)性問題

球(qiu)(qiu)回彈(dan)(dan)性的(de)(de)試驗是將籃球(qiu)(qiu)從6.6英尺的(de)(de)高(gao)度落到(dao)運動(dong)地板上，測(ce)試籃球(qiu)(qiu)的(de)(de)回彈(dan)(dan)高(gao)度。這個數(shu)據以(yi)百分比(bi)(bi)表示(shi)，以(yi)籃球(qiu)(qiu)在(zai)水泥(ni)地上回彈(dan)(dan)的(de)(de)高(gao)度為對比(bi)(bi)標準，反(fan)映回彈(dan)(dan)高(gao)度差。室內球(qiu)(qiu)類運動(dong)比(bi)(bi)賽規則(ze)要求，借助地面進行體育比(bi)(bi)賽或訓(xun)練，如籃球(qiu)(qiu)等(deng)(deng)球(qiu)(qiu)類的(de)(de)運動(dong)的(de)(de)起(qi)跳動(dong)作(zuo)和球(qiu)(qiu)體的(de)(de)反(fan)彈(dan)(dan)，要求球(qiu)(qiu)體在(zai)比(bi)(bi)賽場地地面上的(de)(de)反(fan)彈(dan)(dan)比(bi)(bi)較系數(shu)應大于或等(deng)(deng)于90%。
