To evaluate the electromyographic (EMG) activity of the pelvic floor musculature (PFM) that takes place when performing the functional movement screen (FMS) exercise, comparing it with the activation in the maximum voluntary contraction of PFM in the supine position (MVC-SP) and standing (MVC-ST).
A descriptive, observational study conducted in two phases. In the first study phase, the baseline EMG activity of PFM was measured in the supine position and standing during MVC-SP and MVC-ST and during the execution of the seven exercises that make up the FMS. In the second phase of the study, the baseline EMG activity of PFM was measured in the supine position and standing during MVC-SP and MVC-ST and during the FMS exercise that produced the most EMG in the pilot phase: trunk stability push-up (PU). ANOVA, Friedman's and Pearson's tests were used.
All FMS exercises performed in the pilot phase showed a value below 100% maximum voluntary contraction (MVC) except PU, which presented an average value of 101.3 μv (SD = 54.5): 112% MVC (SD = 37.6). In the second phase of the study, it was observed that there were no significant differences ( = 0.087) between the three exercises performed: MVC-SP, MVC-ST and PU (39.2 μv (SD = 10.4), 37.5 μv (SD = 10.4) and 40.7 μv (SD = 10.2), respectively).
There is no evidence of the existence of significant differences in EMG activation in PFM among the three exercises analysed: MVC-SP, MVC-ST and PU. The results show better EMG values in the functional exercise of PU.
评估进行功能性动作筛查（FMS）练习时盆底肌肉组织（PFM）的肌电图（EMG）活动，并将其与仰卧位（MVC - SP）和站立位（MVC - ST）时PFM最大自主收缩的激活情况进行比较。
一项分两个阶段进行的描述性观察性研究。在第一个研究阶段，在MVC - SP和MVC - ST期间以及进行构成FMS的七项练习时，测量仰卧位和站立位时PFM的基线EMG活动。在研究的第二阶段，在MVC - SP和MVC - ST期间以及在试点阶段产生最多EMG的FMS练习（躯干稳定性俯卧撑，PU）期间，测量仰卧位和站立位时PFM的基线EMG活动。使用方差分析、弗里德曼检验和皮尔逊检验。
试点阶段进行的所有FMS练习，除PU外，显示的值均低于最大自主收缩（MVC）的100%，PU的平均值为101.3 μv（标准差 = 54.5）：112%MVC（标准差 = 37.6）。在研究的第二阶段，观察到所进行的三项练习：MVC - SP、MVC - ST和PU（分别为39.2 μv（标准差 = 10.4）、37.5 μv（标准差 = 10.4）和40.
