OBJECTIVE
To evaluate the electrical behaviour of the biceps brachii (BB) and upper rectus abdominis (URA) by surface electromyography (sEMG) during a forearm flexion with and without the Pilates centring technique.
METHODS
Ten female subjects (with a minimum of one week of experience with the Pilates method) were recruited. The long head of the BB and URA were evaluated while an isotonic contraction of the BB was performed using the Pilates breathing technique and powerhouse contraction, followed by another contraction without these techniques. The data were normalised by a maximal voluntary isometric contraction. Normality was accepted, and the paired t-test was used to determine data differences (p < 0.05).
RESULTS
The recruitment increased with the centring technique for both muscles, with greater activity during the concentric compared to the eccentric phase. In addition, this last phase, the centring activation was greater than without the Pilates technique.
CONCLUSION
The Pilates method seems to influence the increase in BB activity during dynamic contraction, especially during the eccentric phase.
目的
通过表面肌电图（sEMG）评估在有和没有普拉提核心控制技术的情况下，肱二头肌（BB）和腹直肌上半部分（URA）在前臂屈曲过程中的电活动情况。
方法
招募了10名女性受试者（至少有一周普拉提方法的经验）。在使用普拉提呼吸技术和核心力量收缩进行BB的等张收缩时，对BB的长头和URA进行评估，随后在不使用这些技术的情况下进行另一次收缩。数据通过最大自主等长收缩进行标准化。接受数据呈正态分布，采用配对t检验来确定数据差异（p < 0.05）。
结果
对于两块肌肉，采用核心控制技术时募集增加，与离心阶段相比，向心阶段的活动更强。此外，在最后这个阶段，核心控制激活比不使用普拉提技术时更强。
结论
普拉提方法似乎会影响动态收缩过程中BB活动的增加，尤其是在离心阶段。
