Eyona nto ibalulekileyo ekugxagxamiseni kukukhawulezisa, okuthetha ukubaleka ngokukhawuleza, nokugqibezela uthotho lwezenzo ezingxamisekileyo ngokukhawuleza.
Usakhumbula na ukuba uLiu Xiang waphumelela nini kwi-110-meter hurdles kwi-Olimpiki ka-2004? Kusachulumancisa ukucinga ngayo.
Ukubaleka ngeentambo kwaqala eNgilane kwaye kwavela kumdlalo apho abelusi babewela iintambo. Wawubizwa ngokuba yi-obstacle course kwaye wawungowemidlalo yamadoda. Iintambo zokuqala zaziziingcingo eziqhelekileyo. Emva koko kwalandela ii-railings ezingcwatyiweyo, kwalandela nee-wood-saw stands. Ukutsiba phezu kwezi ntambo kuyingozi, kunokubangela iingozi kwaye kuthintela ukuphuculwa kwezakhono zokubaleka ngeentambo.
Ngoko ke, ekuqaleni kwenkulungwane yama-20, kwavela uhlobo oluhambayo "oluhambelanayo" lwesithintelo, olwakhuthaza uphuhliso lwetekhnoloji yesithintelo. Ngo-1935, kwaveliswa imilo "L" yesithintelo, kwaye isithintelo sasiza kujika siye phambili ngeekhilogram ezine zamandla okubetha. Isakhiwo esimile okwe "L" sisengqiqweni kwaye sikhuselekile, njengoko besisetyenziswa namhlanje.
