ABSTRACT
CONTEXT Electrical muscle stimulation (EMS) was designed for artificial muscle activation or superimposed training. OBJECTIVES:
To compare the effects of 8 weeks of superimposed technique (ST; application of electrical stimulation during a voluntary muscle action) and EMS on the cross-sectional area of the rectus abdominis, lateral abdominal wall, and on lumbopelvic control.SETTING:
University research laboratory.DESIGN:
Randomized controlled trial.PARTICIPANTS:
Fifty healthy subjects were recruited and randomly assigned to either the ST or EMS group. INTERVENTION The participants engaged with the electrical stimulation techniques (ST or EMS) for 8 weeks. MAIN OUTCOMEMEASURES:
In all participants, the cross-sectional area of the rectus abdominis and lateral abdominal wall was measured by magnetic resonance imaging and lumbopelvic control, quantified using the single-leg and double-leg lowering tests.RESULTS:
There were no significant differences in the cross-sectional area of the rectus abdominis (right P = .70, left P = .99) or lateral abdominal wall (right P = .07, left P = .69) between groups. There was a significant difference between groups in the double-leg lowering test (P = .03), but not in the single-leg lowering test (P = .88). There were significant differences between the preintervention and postintervention in the single-leg (P < .001) and double-leg lowering tests (P < .001).CONCLUSIONS:
ST could improve lumbopelvic control in the context of athletic training and fitness.Palavras-chave
