Summary The purpose of this study was to investigate the multidirectional lip‐closing force in adult females before and after short‐term lip training. Sixty‐six Japanese females participated in this study. The subjects performed lip training that involved maintaining 200 or 400 g of bottled water in the oral vestibule. The signals of directional lip‐closing force were investigated in eight directions before training and 5 and 7 days after the lip training. The differences in the closing force between pre‐ and post‐training were then analysed statistically. The lip‐closing force increased in the following order: pre‐training, 5 days post‐training and 7 days post‐training in every direction ( P < 0·05). The patterns of the increase in the lip‐closing force in the upper, lower, right and left directions as a result of the repetitions were similar. No significant differences were noted between the training effects with loads of 200 and 400 g. Our findings demonstrated that the lip‐closing force was influenced by the short‐term lip training.
