Ingabe Ukwelapha Okukhanyayo Okubomvu Kungathuthukisa Amandla Emisipha?

Ososayensi base-Australia nabaseBrazil baphenye imiphumela yokwelashwa okulula ekusebenziseni ukukhathala kwemisipha kwabesifazane abasebasha abangu-18.

Ubude begagasi: 904nm Umthamo: 130J

Ukwelashwa okulula kwakunikezwa ngaphambi kokuzivocavoca, futhi ukuvivinya umzimba kwakuhlanganisa isethi eyodwa yama-concentric quadricep contractions angu-60.

Abesifazane abathola ukwelashwa nge-laser ngaphambi kokuzivocavoca "banciphise kakhulu ukukhathala kwemisipha" futhi "banciphisa izilinganiso zokuzikhandla okucatshangwayo."

Ukwelashwa kokukhanya "kwenyuswe i-torque ephezulu, isikhathi sokukhuphuka kwe-torque, umsebenzi ophelele, amandla amaphakathi, kanye ne-torque ephezulu."

Ucwaningo lwaphetha ngokuthi ukwelashwa okukhanyayo "kwakuphumelela ekunciphiseni amazinga okukhathala nokwandisa ukusebenza kwemisipha" kwabesifazane abasha.
