Electromyography study of skeletal muscle during locomotion in a treadmill test: a case study.

Recent researches are trying to rebuild an important human history of its posture and march from the anatomic function evolutions of the skeletal muscle (10, 11, 9, 2). The aim of this study is to verify electromyography data of muscles recto femoris, iliocostalis, gluteus maximus, erector spinae, semitendinosus during human locomotion in two different treadmill protocols (Naughton and Bruce). Data analyses, such as mean was calculated on the Word Office Excel. For electromyography data Aqdata program was utilized. Muscles rectus femoris, iliocostalis, gluteus maximus, erector spinae, semitendinosus were studied using electromyography analyses during human locomotion in treadmill. A number of six individuals was selected for this research. For the Bruce test all individuals ended there participation in the test on the fourth or fifth stage. For the Naughton test all individuals completed the 21 minutes walking. For the Bruce test all the muscle had higher RMS mean when compared with Naughton test, due the effort level for each test.
