運(yun)(yun)動(dong)(dong)(dong)時，我們會排泄大量的汗液，身體消(xiao)耗比較(jiao)大，其中被消(xiao)耗的就是(shi)水(shui)分、糖分、電解質(zhi)。很多人喜歡喝運(yun)(yun)動(dong)(dong)(dong)飲(yin)料來補充(chong)所失的營養(yang)。但是(shi)專家建議，運(yun)(yun)動(dong)(dong)(dong)不超過2個(ge)小(xiao)時的話，不太需(xu)要(yao)喝運(yun)(yun)動(dong)(dong)(dong)飲(yin)料。如果運(yun)(yun)動(dong)(dong)(dong)少(shao)于1小(xiao)時，可以適當喝一些(xie)白(bai)開水(shui)或是(shi)天(tian)然礦泉水(shui)補充(chong)機能。如果運(yun)(yun)動(dong)(dong)(dong)量大，運(yun)(yun)動(dong)(dong)(dong)時間(jian)有1.5-2小(xiao)時，可以適當喝些(xie)運(yun)(yun)動(dong)(dong)(dong)飲(yin)料，補充(chong)身體確實的營養(yang)素(su)，保持運(yun)(yun)動(dong)(dong)(dong)的強(qiang)度(du)。
