Abstract

The Pilates method has been widely used in physical therapy and physical conditioning due to its ability to promote body stability, motor control, and muscle strengthening. Among its classical exercises, the Hundred and Teaser stand out for their high demand on the core muscles. In this context, surface electromyography is an important tool for assessing muscle recruitment. This study aimed to compare the electromyographic activity of the rectus abdominis and rectus femoris muscles during the performance of the Hundred and Teaser exercises, with and without resistance. This is a quantitative, experimental, and comparative study involving 10 female university students. Muscle electrical activity was assessed using surface electromyography, with electrodes positioned according to SENIAM recommendations. Participants performed the exercises in a standardized manner under supervision, allowing muscle activation to be compared under different conditions. Results: Greater activation of the rectus abdominis was observed under the resistance condition (157.78 ± 70.90 µV) compared to the condition without resistance (138.24 ± 58.87 µV), showing a statistically significant difference (p = 0.017). For the rectus femoris, activation decreased under resistance (109.54 ± 24.86 µV) compared to the condition without resistance (131.94 ± 65.78 µV), with no statistical significance (p = 0.286). Conclusion: Resistance influenced muscle recruitment differently, promoting a significant increase in rectus abdominis activation, without a significant change in rectus femoris activation. These findings reinforce the importance of carefully selecting Pilates exercises according to therapeutic and functional goals.
