aF-Ex: Group performed five sets of standing back extension exercise after performing the task to fatigue the lumbodorsal muscles. bnF-Ex: Group performed five sets of standing back extension exercise without performing the task to fatigue the lumbodorsal muscles. cF-nEx: Group remained standing for the same duration as the F-Ex group without performing standing back extension exercise after the task to fatigue the lumbodorsal muscles. dpre-Ex: Resting standing position before exercise. epost-Ex1–5: Standing position after standing back extension exercise 1–5 times. fIntra-factor: p < 0.05 (pre v.s. post3, 4, 5). gInter-factor: p < 0.05 (F-Ex, F-nEx v.s. nF-Ex). hInter-factor: p < 0.05 (F-nEx v.s.
