Mu 2015, ofufuza aku Brazil ankafuna kudziwa ngati chithandizo cha kuwala chingamange minofu ndikuwonjezera mphamvu mwa othamanga 30 aamuna. Kafukufukuyu anayerekeza gulu limodzi la amuna omwe ankagwiritsa ntchito chithandizo cha kuwala + masewera olimbitsa thupi ndi gulu lomwe linkachita masewera olimbitsa thupi okha komanso gulu lowongolera.
Pulogalamu yochita masewera olimbitsa thupi inali ya masabata 8 a maphunziro a extensor a bondo.
Kutalika kwa Mafunde: 810nm Mlingo: 240J
Amuna omwe adalandira chithandizo chopepuka asanaphunzire "adafika pamlingo wapamwamba kwambiri" poyerekeza ndi gulu lochita masewera olimbitsa thupi lokha "poganizira makulidwe a minofu, torque ya isometric peak ndi torque ya eccentric peak."
Ndipotu, makulidwe a minofu ndi mphamvu zimawonjezeka ndi zoposa 50% kwa iwo omwe adagwiritsa ntchito chithandizo cha kuwala asanayambe kuchita masewera olimbitsa thupi.
