Title: Electromyographical Study Of The Iliocostalis Lumborum And Gluteus Maximus Muscles During Locomotion On A Treadmill And In A Ground.

Abstract: The aim of this work was to study the potential action of the Iliocostalis lumborum and gluteus maximus muscles by electromyography during locomotion in a ground and on a treadmill in 10 male subjects ages 19 to 25 years old. To the locomotion in a ground, the subjects started running in a stationary place for 15 seconds and then ran 10 meters at an average speed of 6.0 mph. To locomotion on a treadmill it was also set 6.0 mph during 60 seconds. The registers presented here refer to the last 5 seconds to treadmill test and during the first 5 seconds to test in a ground. A LYNX- AI 6010 electromyography containing 6 channels was used for this study. It was established a frequency of 1200 Hz to acquire the electromyography's registers, being the low pass filter 600 Hz and the high pass filter 10 Hz. The configuration of the entrance limits of the signals was established at 2000 microV (high limit) and -2000 (low limit)microV for both muscles on a treadmill and in a ground. The results of the muscular potential actions presented in RMS were greater on a treadmill for both muscles, with the predominance of the gluteus maximus muscles when it was compared in a ground. When they were compared between them, the gluteus maximus muscle was more active than the Iliocostalis lumborum muscle.
