Abstract
low back pain (LBP) is a significant issue and the aim of study was to compare two protocols, stretching exercises and combination of Pilates, regarding their effects on pain, disability, and electromyographic activity of core muscles in women with LBP.
This research employed a semi-experimental clinical trial design with pre-tes, post-test measures and a control group. Thirty women aged 20-35 with LBP were randomly assigned to three groups. Pain using a visual analog scale, disability using the Roland-Morris Questionnaire, and electromyographic activity was measured using bilateral electromyography. The experimental groups performed their exercises for 8 weeks, control group continued their regular daily activities.
Both protocols were effective in reducing pain and disability while increasing electromyographic activity of muscles. Analysis revealed significant differences in post-tests between the intervention groups and the control group. However, no significant difference was observed between the two intervention groups. The results means indicated a greater effect of the combination exercises compared to stretching exercises alone.
The results suggest that stretching exercises and a combination of Pilates are effective in reducing pain, disability and increasing electromyographic activity of core muscles in individuals with LBP. it is recommended to utilize these exercises for improving non-specific chronic LBP.

Abstract
The prevalence of sports injuries in martial arts is high. Most Taekwondo injuries also occur in the lower extremities. The aim of this study is to compare the effect of a period of plyometric exercises, with and without stretching exercises, on knee valgus dynamics, flexibility and functional variables of elite female taekwondo athletes at risk of anterior cruciate ligament injuries. 45 elite female taekwondo athletes aged 15-25 years with anterior cruciate ligament injuries participated in this study. Knee valgus dynamics in squat movement were measured with KINOVEA software. Flexibility was measured with direct leg lift test and performance indicators were measured with Y-balance, three-step jump and error scoring system. The tests were conducted before and after eight weeks of plyometric exercises, along with the stretching exercises. Then, the data obtained were analyzed.There was a significant difference between the results of pre-test and post-test data measured in the two experimental groups (P ≥ 0.05). According to the stark differences based on the analyzed data, it is clearly evident that the group of athletes with plyometric exercises with stretching have obtained far superior results and outcome..Plyometric exercises with stretching had a significant effect on reducing the risk of injury, as well as increasing the flexibility and performance of elite female taekwondo athletes exposed to anterior cruciate ligament injury. Considering the vast improvements reported for the plyometric training group with stretching, it is recommended that these interventions be used to reduce the risk of injury and increase the performance of taekwondo practitioners.

Abstract
The aim of this research was effect of eight weeks of neuromuscular training (NMT) with and without cognitive-dual tasks (DTs) on proprioception and balance of athletes with ACL deficiency (ACL-D). 39 soccer players with ACL-D were selected purposefully and randomly divided into three groups of 13 (control group, neuromuscular training group and neuromuscular training with dual tasks group). Two training groups performed the exercises for eight weeks and three sessions per week. cognitive-motor dual tasks were performed in one of the groups along with neuromuscular exercises in the form of counting down numbers, memorizing numbers, calculating unexpected equations, specialized football skill movements. The results of the current study indicated that there was no significant difference in knee joint proprioception in the open and closed kinetic chain after applying the intervention between the three groups, but there was a significant difference in lower extremity performance of the athletes based on the Y balance test in the anterior and posterior-lateral direction between the three groups (p<0.05). It seems that providing neuromuscular exercises along with cognitive-dual tasks can probably be considered as a useful approach to improve lower extremity performance based on the Y balance test in athletes with anterior cruciate ligament deficiency.
