Figure 4.
Differences in the NiEMG (%MVIC) between muscle and degree (A) Hamstrings NW; (B) Hamstrings WT; (C) Related muscle NW; and (D) Related muscle WT at each knee flexion angle during 45° hip extension exercise (ECC). BF=biceps femoris; ST=semitendinosus; SM=Semimembranosus; ES=Erector spinae; GM=Gluteus maximus; AD= Rectus abdominis; MVIC= maximal voluntary isometric contractions; NW=non-external resistance; WT= 5kg load; ECC=eccentric. The symbol* indicated statistical significance between 0° and other degrees, and symbol vs. indicated statistical significance between muscles.
