Lub hauv caug Kinematics Thaum ua haujlwm squats nrog cov hlua tiv thaiv, ob qho tib si eccentric thiab concentric theem ua rau kom lub hauv caug valgus lub kaum sab xis thiab siab tshaj tibial kev sib hloov.
Tshwj xeeb, thaum lub sij hawm 80% 1RM squats, lub hauv caug valgus lub kaum sab xis nce los ntawm 28% nrog hnyav tiv thaiv bands thiab los ntawm 37% thaum 40% 1RM squats.
Thaum lub sij hawm eccentric theem, lub kaum sab xis valgus nce 32% ntawm 80% 1RM thiab 27% ntawm 40% 1RM.
Qhov siab tshaj plaws tibial kev sib hloov lub kaum sab xis tau nce los ntawm qhov nruab nrab ntawm 1.78℃ntawm 80% 1RM thiab 1.75℃ntawm 40% 1RM thaum siv cov hlua hnyav hnyav piv rau tsis muaj kev tiv thaiv band.
Cov leeg nqaij ua haujlwm Resistance bands tau nce gluteus maximus (GM) ua kom muaj zog.
Tshwj xeeb, hnyav tiv thaiv bands nce GM EMG los ntawm 13.25% thaum lub sijhawm siab -load squats thiab los ntawm 23.15% thaum qis-load squats.
Hauv qhov sib piv, kev ua kom lub vastus lateralis (VL) thiab vastus medialis (VM) txo qis, tshwj xeeb tshaj yog thaum qis -load squats qhov twg lub ncov VL EMG tau qis dua nrog cov hlua hnyav dua li qhov tsis muaj.
Cov kev tshawb pom no qhia tias kev tiv thaiv bands tsis txo qis hauv caug varus lossis tibial kev sib hloov tab sis hloov cov ces kaum, uas ua rau muaj kev pheej hmoo ntawm lub hauv caug raug mob.
Tsis tas li ntawd, cov pab pawg tiv thaiv feem ntau txhim kho gluteus maximus activation thaum muaj kev cuam tshuam rau lwm yam hauv qab - cov leeg nqaij.
Cov kev tshawb pom tseem ceeb thiab cov lus xaus Cov kev tawm tsam kuj ua rau lub hauv caug varus lub kaum sab xis thiab qhov siab tshaj plaws tibial rotation lub kaum sab xis, muaj peev xwm ua kom muaj kev pheej hmoo ntawm lub hauv caug raug mob.
Thaum gluteus maximus ua kom muaj zog nce ntxiv, lwm cov leeg qis dua -limb leeg qhia kev txhim kho tsis raug.
Qhov no qhia tau hais tias yuav tsum ceev faj thaum siv cov hlua tiv thaiv hauv kev cob qhia thiab kev kho kom rov zoo.
Thaum cov hlua tiv thaiv tau nce gluteus maximus activation, lawv kuj tseem nce lub hauv caug varus lub kaum sab xis thiab siab tshaj tibial rotation lub kaum sab xis, muaj peev xwm ua kom muaj kev pheej hmoo ntawm lub hauv caug pob qij txha raug mob.
Yog li, cov kws qhia thiab cov kws kho mob tau qhia kom ua tib zoo xav seb puas yuav txuas ntxiv siv cov hlua tiv thaiv rau kev cob qhia squat, thiab cov kev tshawb fawb yav tom ntej yuav tsum tau soj ntsuam ntxiv rau lawv qhov ntev -cov teebmeem thiab poj niam txiv neej- qhov txawv tshwj xeeb.
