Background. Low Back Pain (LBP) is a prevalent phenomenon in athletes and asymmetrical loading on the limbs has been proposed as a risk factor related to this disease.
Objectives. The purpose of the present study was to compare the asymmetry of loading applied on the legs between men with and without LBP during gait.
Methods. A total of 40 participants, comprising 20 men with non-specific LBP who practiced martial arts and 20 men without LBP, participated in the study. The participants walked in gait lab and forces applied on the legs were recorded in three dimensions using a force plate. Also, asymmetry of the forces applied on the dominant and non-dominant limbs was measured.
Results. The Asymmetry Indexes (ASI) of the first, second, and third peaks of vertical forces were respectively 3.1%, 3.4%, and 4.1% for normal participants and 4.2%, 4.2, and 2.1 for the participants who had LBP (p>0.05).
Conclusion. It can be concluded that martial arts athletes with LBP apply symmetrical loads on the lower extremities, similar to healthy people.

Low Back Pain (LBP) is a prevalent phenomenon in athletes and asymmetrical loading on the limbs hasbeen proposed as a risk factor related to this disease.
The purpose of the present study was to compare theasymmetry of loading applied on the legs between men with and without LBP during gait.
It can be concluded that martial arts athletes with LBP apply symmetrical loads on the lowerextremities, similar to healthy people.
Therefore, study of the pattern of loads applied onthe legs in athletes with musculoskeletal symptoms,especially LBP, seems to be critical.
However, noreported study has yet investigated the pattern offorces applied on the legs in martial arts athleteswho have LBP.
Asymmetrical loading on the limbs during gait mayresult in different musculoskeletal pain syndromessuch as LBP (21, 24, 25).
However, no study has yet investigated symmetricalload applied on the legs during gait in LBP athleteswho practice martial arts.
study; when ASI of loads applied onthe legs were compared between the groups, nosignificant difference was observed.
Basedon the results obtained in the present study, we alsoneed to examine other mechanical risk factorswhich may be related to LBP in patients whopractice martial arts sports activities.
Evaluation of differencesbetween two groups of low back pain patients with and without rotational demand activities based on hip andlumbopelvic movement patterns.
