Core stability and strengthening of core stability muscles are among the new debates in sports medicine. The present study aimed to determine the effect of CX WORX exercises, one type of stability exercise, on proprioception and strength of selected muscles in basketball players with trunk defects.

Thirty female basketball players with trunk defects were selected by available sampling and randomly placed in two control and training groups. Trunk defects through the tuck jump test, knee, and ankle proprioception using a goniometer, trunk proprioception using Kinovea software, the strength of knee flexors and extensors, hip abductors and external rotators, and basketball players' trunk flexors and extensors using a dynamometer were evaluated. CX WORX exercises were performed by the training group for six weeks. Paired sample t-tests and covariance analysis were used to analyze the data.

The results of the present study show a significant effect of CX WORX exercises on trunk (P=0.014), ankle (P=0.000), and knee (P=0.000) proprioception and the strength of knee (P=0.000), and trunk extensors (P=0.000), abductors (P= 0.000) and external rotator of the hip (P=0.000) of the subjects of the experimental group compared to the control group, but no significant difference was observed between the strength of the knee flexor muscles between the two groups (P>0.05).

According to the results, CX WORX exercises improved trunk, ankle, and knee proprioception and the strength of the knee and trunk extensor, hip abductor, and external rotator muscles of basketball players with trunk defects. Therefore, it is suggested that experts in the field of health and corrective exercise use CX WORX exercises with the aim of increasing proprioception and muscle strength of basketball players with trunk defects.

The purpose of this study was to investigate the effect of eight weeks of core stability exercises on upper limb performance based on Y balance test, strength and range of motion of shoulder rotation in badminton athletes. 30 male badminton players were randomly assigned to two control (n=15) and experimental (n=15) groups. The experimental group performed the core stability training program for eight weeks, three sessions a week for 40 minutes, while the control group did not receive any intervention. Measurement of upper limb function was done by Y balance test, and also shoulder strength and internal and external rotation range of motion were measured by handheld dynamometer and goniometer respectively, before and after the intervention. The analysis of the data obtained from the research based on the ANCOVA statistical test showed that there is a significant difference in the average of the Y upper limb balance test between the two control and experimental groups in both dominant and non-dominant hands. which indicates the positive effect of core stability exercises on people's performance in performing the Y balance test (p<0.05); however, no statistical difference was observed in muscle strength and range of motion of external and internal rotation of the shoulder after the intervention. (p < 0.05). It seems that the provision of core stability training programs can be considered with the approach of increasing the performance of the upper limbs and, of course, preventing injuries in badminton players.

Strengthening the muscles of the central area of the body to increase core stability is considered a part of the training program of athletes. The purpose of this research was the relationship between core stability exercises with upper and lower limb muscle function and also to improve the functional movement screening (FMS) score.

This research is of practical and semi-experimental type, which is available on 30 male basketball athletes with an average age of 19/55±1/3 and an average weight of 69/48±7/1 into two control (15) and experimental (15) groups were divided. To strengthen the central muscles, the subjects were given 4 specific exercises for upper and lower limb muscles (side plank, deep squat, sit up) before and after the test. To measure the score of the functional movement screening test, the FMS seven-step test was used, that is, all people participated individually in the seven test steps in both the pre-test and the post-test. Statistical analysis was done using SPSS version 18 software. A significant level was considered in this study (P₌0.05).

The changes in the screening test between the groups (control and experimental) (P<0.05) and also the changes in the squat test (p=0.000), swimming (p=0.011), and barfix (p=0.003) had significant differences.

Eight weeks of central stability exercises affected the improvement in the performance of upper and lower limb muscles, and the score of the screening test in male basketball players increased. It is suggested that coaches use this test in other sports as well.

The aim of the present study was to compare the effect of six weeks of core stability training on bosuball and balance board on balance, speed and range of motion of the ankle in adolescent boys.

In this quasi-experimental study, 30 adolescent boys were purposefully and accessibly selected as subjects and were randomly divided into three groups:10 in the balance board training group,10 in the bosuball training group, and10 in the control group.The training program consisted of six weeks of core stability training in two experimental groups, bosuball and balance board .24 hours before the pre-test and after the implementation of the training protocol, all subjects in the three groups of Y test were performed to assess balance, 36-meter running test to assess speed and measure ankle range of motion. K-S test was used to evaluate the normality of the data, Levin test was used to determine the homogeneity of variances, and one-way ANOVA analysis was used to analyze the data, and Bonferroni test was used to determine the mean pair difference.

Based on the results and findings of the research on post-test scores, the exercises of the bosuball group and the balance board in the factors of balance, speed and range of motion of the ankle, showed a significant difference with the control group.

The results of this study showed that core stability training on bosuball and balance board improves balance, speed and range of motion factors of adolescent boys.

Proprioception is a part of the body sensory system which is responsible for collecting information for the central nervous system in order to inform the condition of parts of the body. One of the causes of impaired proprioception, is fatigue. The aim of this study was to compare the effects of Core muscle fatigue on pelvic and knee Proprioception and the amount of balance types of athletes and non-athletes.

30 men (15 athletes and 15 non-athletes) as a pre-test, preformed pelvic and knee proprioception and balance (static and dynamic) tests. In the second session, individuals participated in core muscle fatigue protocol and immediately underwent proprioception and balance tests in fatigue conditions. covariance method was used to compare the results between before and after fatigue protocol. Significance level (p≤0.05) was considered.

The findings showed that there was a significant difference between the effect of core muscle fatigue in pelvic proprioception at an angle of 30 degrees (p=0.002), knee proprioception at an angle of 60 degrees (p= 0.007), and dynamic balance (p= 0.001) among athletes and non-athletes. This difference was not significant in static balance (p= 0.072).

Reinforcement the core muscles to prevent sports injuries should be given special attention by coaches and athletes. Considering the relationship between of the fatigue and the increase in the sports injuries, core muscle fatigue, especially in non-athletes, can be considered an alarm and minimal physical activity with emphasis on reinforcement the core muscles be recommended to everyone.

One of the issues that has been considered by sports researchers today is the claim of the effect of functional differences in the muscles of the core stability area on the results of kinematic and kinetic variables during the activities of athletes and non-athletes. The aim of this study was to investigate the interaction between lateral core stability area muscles function, ground reaction force and changes in center of mass to pressure in the Medio-lateral direction during gait according to the level of physical activity. Eighteen young men in two groups of 9 athletes and non-athletes participated in this study as subjects. Electrical activity of internal and external oblique muscles and information on the ground reaction force and changes in the center of mass to the presser were recorded during gait. The T-test was used to compare the results of the two groups at p ≤ 0.05. The duration of electrical activity of the external oblique muscle of athletes and non-athletes showed a significant difference (0.005), while no significant difference was observed in the electromechanical delay of the muscles. There was a significant difference between the two groups in the changes in center of mass to pressure of the Medio-lateral direction (0.041). The results of the study confirmed the interactive effect of the lateral core stability muscles and the behavioral pattern of changes in the center of mass to pressure and the ground reaction force in the Medio-lateral direction according to the level of physical activity during gait.

Cesarean is a way to save the life of mother and baby during childbirth.The aim of this study was to investigate the effect of eight weeks of core stability exercises on low back pain, lumbar lordosis and quality of life of women with a history of cesarean delivery.

Study population consisted 20 to 30 year old women with a history of cesarean section who had spent at least 6 and at most 12 months since their cesarean section in Hajar Hospital in Shahrekord. 32 available samples were selected and randomly divided into experimental and control groups. Subjects completed the Quebec Questionnaire and the World Health Organization Quality of Life Questionnaire and their lumbar lordosis was assessed by flexible ruler. Experimental group performed core stability exercises for 8 weeks three sessions per week and Control group did not exercise. participants were evaluated again by previous tests. Data were analyzed by multivariate analysis of covariance at a significance level of 0.05.

Results showed that eight weeks of core stability exercises had a significant effect on reducing low back pain and improving the quality of life in women with a history of cesarean delivery (P <0.05), while it had no significant effect on reducing female lumbar lordosis (P> 0.05).

core stability exercises focusing on the lumbar-pelvic floor muscles reduce back pain and improve the quality of life of women with a history of cesarean section, so these exercises can be used in this regard.

There was significant difference between the effects of Pilates and core stability training methods on dynamic balance and improve cognitive function.

According to the research findings, the use of these two methods training to improve dynamic balance of older women is recommended. The use of core stability training can improve cognitive performance in elderly females is effective.

 This study aims to assess the effect of 12 weeks of core stability exercises on functional movement and balance of women working in hospitals.

 Participants were 34 women aged 30-50 years working in Imam Khomeini Hospital in Tehran, Iran. They were randomly divided into two groups of exercise and control. The exercise group performed core stability exercises for 12 weeks. The functional movement was evaluated using the valid Function Movement Screen (FMS) method. The dynamic balance, power, agility, speed and flexibility of subjects were also measured using Y balance test, Sargent Jump Test, agility T-test, 20-meter running test, and seated bending forward test, respectively before and after exercise. Paired T-test was used to examine the difference between pre- and post-test scores of each group. Analysis of Covariance (ANCOVA) was used to determine the effect of intervention on the study variables.

 Results of ANCOVA showed that 12 weeks of core stability exercises significantly improved functional movement performance, dynamic balance, power, agility, speed and flexibility in women.

 Core stability exercises can improve the performance of neuromuscular system leading to proper movement of spinal, pelvic and hip joints, proper muscle balance, enhanced proximal stability, functional strength and resulting in decreased injury.

Genu varum is one of the most common disorders of the lower limbs and the person walks on the lateral edge of the foot. The aim of this study was to investigate the effect of 8 weeks combined exercises (core stability and theraband) on distance of knee medial condyles, Q angle, and endurance of core muscles in adolescent students with genu varum. 30 female junior high school students with genu varum purposefully selected and randomly divided into two experimental (age 14/47±0/74years, height 158/80 ±0/93cm and weight 48/80±8/68kg) and control (age 14 ±0/76years, height 157/73 ± 5/18cm and weight 49/13 ±5/22kg) groups (n=15). The distance of knee condyles, Q angle and endurance of core stability muscles of subjects was measured with collis, goniometer, macgill side plank test, respectively. The experimental group completed 8 weeks, 3 sessions per week, and 60 minutes per session of the combined exercises (core stability andtheraband) program Data were statistically analyzed by the use of covariance, using SPSS 25 software (p < 0.05). After the training, there was a significant decrease in the distance between the internal condyles of the knee (P = 0.002), a significant increase in the Q angle (P = 0.007) and endurance of the central muscles (P = 0.001). Therefore, according to the effective results of the exercises of this research, it is recommended to use this training protocol in corrective programs to improve and correct the genu varum anomaly.

 Since direct foot kick is one of the most important strikes in Jeet Kune Do, its effectiveness depends on both the force of the hit and balance control during and after the hit execution, this study undertaken to examine the effect and persistence of eight-week of core stability training on balance and force of a direct foot kick of elite young male Jeet Kune Do (Wushu) athletes.

 24 elite young Jeet Kune Do athletes were randomly assigned to an experimental and a control groups. The experimental group performed the core stability training program for eight consecutive weeks. Static (stork test), dynamic test (tandem test) and force of a direct foot kick of the athletes in both groups were measured in three stages including before, after (eight weeks of core stability training) and a 4-week follow-up detraining period.

 The results showed that core stability training had a significant and persistent effect on static and dynamic balance. However, the training program had no significant effect on the force production of a direct foot kick after a 4-week of detraining period.

 It seems that the core stability training program improves the neuromuscular system function by strengthening the muscles of the core area. This in turn prevents the dislocation of the center of gravity outside the base of support and decreases its oscillation (displacement), therefore, as a result of persistence effect of the program, balance ability and direct kicking power improves.

Data analysis was performed using Paired t-test, One-way analysis of variance and Scheffe Post Hoc.

The findings showed that performance of the experimental group1 and2 have been significantly improved from pre-test to post-test. The difference between groups was significant in comparison between groups; the results of scheffe posthoc test showed that the experimental group1 compared with control group had a significant different. But there was no significant difference between other groups.

The results show that combining core stability physical exercises with mindfulness exercises can be beneficial for the balance of femahe older adults.

 For optimal performance of swimmers, it is necessary to determine a level for the functional interaction of upper and lower limbs. This level, created by more than 20 pairs of muscles, is the core of the body. The aim of this study was to investigate the effects of six weeks of core stability exercise on the stroke index and front crawl record of male swimmers.

 In this quasi-experimental study, 24 male swimmers were selected by a convenience sampling method and randomly assigned into control (n=12) and exercise (n=12) groups. The core stability training was performed for 6 weeks, 3 sessions per week, each for 45-50 minutes. Before and after training, the stroke index and 100-m front crawl records of subjects were evaluated. For the within-group and between-group comparisons, the student t-test and ANCOVA were used, respectively. The significance level was set at P<0.05.

 Six weeks of core stability exercise led to significant improvement in 100-m front crawl record in the exercise group. There was no significant difference in the mean scores of stroke index and 100-meter front crawl record between and within the two study groups.

 Core stability exercise is recommended for dryland training of swimmers.

 Numerous abdominal exercises with Swiss ball are used to improve core stability with strengthening and rehabilitation goals. It is claimed that the stability exercises have a greater impact on core muscle activation, but the validity of this claim is still in doubt. Moreover, there is no comprehensive study on the comparison of the core muscles activity in different core stability exercises. Therefore, the purpose of this study was to compare the Electromyography (EMG) activity of core muscles while performing side plank on stable and unstable (Swiss ball) surfaces.

 Fifteen male students of Allameh Tabataba’i University were selected for the study based on inclusion and exclusion criteria. The EMG activity of gluteus medius, rectus abdominis, external oblique, and internal oblique muscles in subjects was recorded while performing side plank exercise on a fixed surface and a Swiss ball (2 sets of 5 seconds with a 30-second rest interval).

There was a significant difference in the EMG activity of gluteus medius, external oblique and rectus abdominis muscles between two conditions of with and without Swiss ball (P<0.05), but no significant difference was observed in the EMG activity of internal oblique muscle (P>0.05).

 Side plank exercise on the unstable surfaces (Swiss balls) can cause changes in the EMG activity of gluteus medius, rectus abdominis and external oblique muscles compared to when the exercise is performed on stable surfaces, and highly involved the pelvic lumbar muscles effective in maintaining core stability. Therefore, the use of side plank exercise on unstable conditions in a progressive program with gradually increased intensity is recommended which can be effective in strengthening and applying effective muscle contractions useful for core stability.
