Abstract

Purpose

We investigated the effect of resistance training and detraining on the spatial distribution pattern of surface electromyography (SEMG) of the biceps brachii.

Methods

Ten male subjects completed 6 weeks of resistance training of one arm and 8 weeks of detraining. During training and detraining periods, spatial distribution patterns of SEMG were measured and quantified with 64 two-dimensional electrodes.

Results

MVC, muscle thickness, and SEMG amplitude of the trained arm were significantly greater than those of the untrained arm after the 6 weeks of resistance training (p < 0.05), but these differences were no longer observed after 2 months of detraining. On the other hand, no significant differences in the spatial distribution pattern of SEMG were observed between the arms.

Conclusion

Spatial distribution pattern of SEMG was not changed during resistance training and detraining periods. This suggests that detectable adaptations in the motor unit recruitment pattern do not occur during regular resistance training.
