Influence of Different Backpack Loading Conditions on Neck and Lumbar Muscles Activity of Elementary School Children
Influence of Different Backpack Loading Conditions on Neck and Lumbar Muscles Activity of Elementary School Children
The purpose of the present study is to analyze the influence of four backpack loading conditions (0, 10, 15 and 20% of body weight) on the electromyographic activity of the neck and lumbar muscles of elementary school children.
Elementary school children participated in the present study, between the ages of 6 and 10. Bilateral sternocleidomastoid, rectus abdominis and erector spinae muscles activity were recorded using surface electromyography (sEMG), while tested for the effect of four randomized backpack loading conditions.
