Genu varum is one of the abnormalities of the lower limbs. The aim of the present study was to review the effect of exercise training and support tools on biomechanics of transitional movements in people with genu varum.

The present study was a review article. The search for articles in Persian and Latin was from the beginning of 2010 to the beginning of March 2023, which was done in the citation databases of WOS, ISC, SID, Magiran, Scopus, PubMed, and Google Scholar. 32 articles related to the effect of exercise training and support tools on genu varum were analyzed.

Findings of four articles related to aerobic exercises showed an increase in peak reaction forces and loading rate. Findings of six articles showed the positive effects of resistance-corrective exercises due to the improvement of balance and Q angle. Results of two articles showed a reduction in the severity of the abnormality due to the frequent use of the medical floor. Eleven articles discussed the positive effects of orthosis, braces, and wedges. Two articles indicated the increase of Q angle and balance due to the use of kinesio taping. One article demonstrated that the use of kinesio taping can reduce muscle strength. Six articles mentioned the negative effects of the exercise protocol or support tools or have not reported any significant differences.

It appears that performing resistance-corrective exercises along with the continuous use of support tools is more effective compared to performing aerobic exercises.

Changing the direction of the body in fast moving movements is a matter of injury, which is of special importance in the injury mechanism of anterior cruciate ligament (ACL). The present study investigated the kinematic comparison of feint maneuver between dominant and non-dominant legs and its relation with anterior cruciate ligament injuries injury.
In this study, 18 professional female handball players were selected in a targeted and convenience way. The subjects, after attaching the markers, ran for 3 meters and when arrived to marked location on the ground, performed the feint maneuver with their dominant leg and passed the bar. Then, performed the same action with their non-dominant leg. Raw data processing was implemented using Cortex software. Then, the variables of the knee joint (flexion/extension and valgus/varus) entered the SPSS software; and the Shapiro-Wilk test was used to evaluate the normality of the data. Lyon and dependent t tests were used for homogeneity and intragroup comparison, respectively. The significance level was considered at less than 0.05.
The changes in flexion (P = 0.346) and extension (P = 0.322) of knee joint were not significant between dominant and non-dominant legs; but the changes in valgus (P = 0.001) and varus (P = 0.001) of knee joint were significantly different between the dominant and non-dominant legs.
The results of this study will help to understand the risk factors of kinematics in risky situations better, and thus can teach the correct way of performing techniques to athletes exposed to high-risk situations. It is better to use protective instruments such as brace or kinesiotape while doing this techniques.

Recognition of deformities and corrective exercise is a branch of physical education which intends to emend and treat various muscular weaknesses and deformities using proper and accurate corrective exercise and sports scientific principles.The aim of this study was to investigate the effect of regular corrective exercise on skeletal deformities such as scoliosis, shoulders dropping, flat foot and bow leg in secondary school male students of Khorramabad city as the statistical population.

160 girls in khorramabad city, aged 12-14 years, participated in this study. The subjects were examined twice before and after 24 sessions of corrective exercise. Deformities were measured by grid plane, plumb line and other relevant tests. The gathered data were analyzed by descriptive statistical methods including: frequency, percentage and graphs.

In 12 years old sbjects the degree of shoulders dropping, flat foot and bow leg in post- test were lower than pre-test and differences were significant (F=7.96, P<0.001& F=100.1, P<0.001 & F=27.63, P<0.001), but scoliosis was not significant (F=3.32, P>0.001). The differences between pre and post measurments of shoulders dropping, flat foot and bow leg in 13 years old cases were significant (F= 100.1, P<0.001 & F=27.63, P<0.001 F=7.96, P<0.001),but for scoliosis, the differences were not significant (F=3.32 & P>0.001). Finally in 14 years old subjects for shoulders dropping, flat foot and bow leg, differences between pre and post- test were significant (F=7.96, P<0.001 & F= 100.1, P<0.001& F=27.63, P<0.001) but scoliosis were not significant(F=3.32, P>0.001).

The findings of this study emphasize the reliable, accurate, feasible, and easy methods for decreasing abnormalities. Furthermore, it showed that the corrective exercise programs, can reduce the abnormalities in oldness.
