Ngo-2015, abacwaningi baseBrazil babefuna ukuthola ukuthi ukwelashwa okulula kungakha yini imisipha futhi kuthuthukise amandla kubadlali besilisa abangu-30. Ucwaningo luqhathanise iqembu elilodwa lamadoda asebenzisa ukwelashwa okulula + ukuzivocavoca neqembu elalizivocavoca kuphela kanye neqembu elilawulayo.
Uhlelo lokuzivocavoca lwaluyizinsuku ezingu-8 zokuqeqeshwa kwe-knee extensor.
Ubude begagasi: 810nm Umthamo: 240J
Amadoda athola ukwelashwa okulula ngaphambi kokuqeqeshwa “afinyelele ushintsho oluphezulu kakhulu ngamaphesenti” uma kuqhathaniswa neqembu lokuzivocavoca kuphela “ngobukhulu bemisipha, i-isometric peak torque kanye ne-eccentric peak torque.”
Eqinisweni, ukujiya kwemisipha kanye namandla kwanda ngaphezu kuka-50% kulabo abasebenzisa ukwelashwa okulula ngaphambi kokuzivocavoca.
