Resumo

Electromyography (EMG) is a technique to monitor the electrical activity of excitable membranes, and they are applied in striated skeletal muscles. We studied the gluteus maximus muscle (GMM) by EMG in 15 male subjects, aged 19~25. They were considered healthy, without problems in walking and performing physical activities. Considering this, we aimed at studying the action potentials on the ergometric treadmill (Bruce and Naughton Protocol). The work was conducted at the Laboratory of Electromyography and Biomechanics of Posture, School of Physical Education, University of Campinas (Unicamp). For this study, we used a Lynix® electromyograph (PS6040), containing six channels, acquired from the FAPESP support 1996/5708-4. To acquire the EMG recordings, we established the frequency of 1199.760 Hz. The instrument was calibrated with 2000 HZ gain, low-pass filter of 600 Hz and high-pass filter of 10Hz. Setting input signal limits was established in 3000 uV (upper limit), -3000 uV (upper limit), and input range from -5 V to +5 V. The test parameter was simple type, and the graphics mode was calibrated in x+y+z+w.t, allowing to demonstrate records simultaneously for each experiment. The electrodes were placed at 10 cm above the insertion point (gluteal femur tuberosity). Considering the ergometric treadmill, we used the Bruce and Naughton protocol. The recordings were made in the last 10 seconds for each protocol stage, noting that the Naughton protocol model II has eight stages. We used adhesive-type surface electrodes (Bio-logic®) to capture the EMG signals. By the results collected from the EMG signals, GMM was quite required. Further, such results were transformed in RMS for the walking activity by using an ergometric treadmill, specifically based on the Bruce protocol, followed by the Naughton protocol.
