An electromyographic analysis of two techniques for squat lifting and lowering.
The purpose of this study was to examine the effects of two different alignments of the pelvis and three different loads on electromyographic (EMG) activity of the erector spinae and oblique abdominal muscles during squat lifting and lowering. Each of 15 healthy subjects lifted and lowered loads with the pelvis aligned both in an anterior tilt and in a posterior tilt. Based on total duration, b...
متن کاملComparison of electrical and co-contraction activity of selected lower limb muscles during manual load lifting with three different technique
Introduction and Aim: Manual handling of loads is a complex dynamic task that involves the upper and lower limbs. Manual handling of loads in sports and daily activities can expose people to unfavorable physical conditions and lead to injury. The study aimed to compare the electrical activity and co-contraction of selected lower limb muscles during manual load lifting with three different techn...
متن کاملComparison of electromyography activity of abdominal muscles and hamstrings in women with low back pain during different lifting positions
Objective: back pain is one of the most common health problems in different societies of the world, especially in industrialized countries. The aim of this study was to compare the electromyography activity of abdominal muscles and hamstrings in women with low back pain in different lifting positions. Methods: The present study was a quasi-experimental and laboratory study. The statistical sam...

Background: There is considerable professional debate over which technique is the best for lifting. The aim of this study is to compare three static lifting styles, the stoop, semi-squat and arm lift, using maximum isometric voluntary contraction (MIVC) as one indicator for recommending a lifting style. Methods: Thirty healthy women (mean age: 22.37 years) participated in this quasi-experiment...
متن کاملNeuromuscular coordination of squat lifting, I: Effect of load magnitude.
BACKGROUND AND PURPOSE In this study, we examined changes in kinematic and electromyographic (EMG) measurements of the coordination (ie, the relative timing of joint movements and muscle activity) of a squat-lifting task in response to lifting increasing loads. SUBJECTS Fifteen male industrial workers served as a sample of convenience. METHODS Subjects lifted a weighted crate containing 15%...
