Q. Ngaba kukho nawuphi na umahluko, ukomelela, phakathi kokubaleka kwi-treadmill nokubaleka ngaphandle?

Impendulo ixhomekeke ekubeni ubaleka kangakanani. Kumntu ophakathi, ebaleka i-6-9 mph kwibhodi yetyhubhu yempilo eklabhu, umahluko mncinci, mhlawumbi awukho kwaphela. Olunye uphononongo alubonisi mahluko konke konke phakathi kwetrama yokunyathela nokusebenza kwangaphandle; olunye uphando lubonisa ukubaleka kwangaphandle kutshisa i-3-5 yeepesenti ngaphezulu kweekhalori. "Ibhanti lokunyathela lenza umsebenzi omncinci ngokunceda ukutsala iinyawo zakho phantsi komzimba wakho," utshilo uJohn Porcari, Ph.D., unjingalwazi kwisebe lokuzilolonga kunye nesayensi yezemidlalo kwiYunivesithi yaseWisconsin, eLaCrosse. (Isinqe esinexabiso eliphantsi, esinebhanti elingahambi kakuhle, ayizukunceda kangako ngomatshini okumgangatho ophezulu, ke uya kutshisa inani elifanayo leekhalori njengaxa ubaleka ngaphandle.)

Xa ubaleka kwi-treadmill, akunyanzelekanga ukuba woyise ukumelana nomoya, oko kunokuchaza umahluko omncinci wokutsha kweekhalori. Ukuba ubaleka ngokukhawuleza kune-10 mph--isantya esikhawulezayo semizuzu emithandathu-emayile-ukuqhuba ngaphandle kunokutshisa ukuya kuthi ga kwi-10 leepesenti ngaphezulu kweekhalori kunokuba ubaleke kwi-treadmill kuba usebenza nzima ngokuchasene nokumelana nomoya.
