A biomechanical analysis of the spine during two types of lifting

Abstract EN

Studying the mechanical aspects of spinal injuries is the base for preventing these injuries and protecting this most moving vital part of the body.

While lifting, athletes make hypotheses about weight and load distribution and, accordingly, plan the lift.

It is well-documented that there is a strong correlation between lifting and low back pain.

The current research aims at identifying the differences in trunk movements and trunk extensor muscles during two positions of lifting (squat – leaning).

The researcher used the descriptive approach on sample of (30) athletes.

Data collection tools included EMG, Motion Analysis System and Bar and weights.

The researcher concluded that there are major differences in EMG measurements of the Erector Spinae Muscle and trunk movements between the two types of lifting.

The researcher recommended that wearing supporters while lifting and its effects on the variables under investigation should be studied.
