Abstract
Floss banding, as a new and effective technique, is becoming increasingly popular in the field of sports training, sports injury prevention, and rehabilitation. Given the need for further studies on the effect of floss banding on isometric strength and neuromuscular activity, this study aims to investigate the effect of floss banding. This study was conducted on judo players with a training history of at least two years and an age range of 20-30. The test method was as follows: first, the subjects were given an isometric strength test using a dynamometer, and at the same time, the neural and muscular activity was recorded using an EMG device. Then, the floss band was wrapped according to the protocol and after that, the strength and neuromuscular activity test was taken from the subjects immediately and 20 minutes after unwrapping the floss band. The results showed that eight weeks of floss banding had no significant effect on isometric grip strength from the pre-test to the post-test (p=0.096). The test results showed that there was no significant difference between the average isometric grip strength of judo players during the measurement stages (p=0.75). There was no significant difference between the average surface electromyography activity of the FCR muscle of judo players during the measurement stages (p=0.94). There was no significant difference between the average surface electromyography activity of the FCU muscle of judo players during the measurement stages (p=0.51). According to the results, using floss bands in a single session had no significant effect on the isometric grip strength and the electromyography activity of the superficial flexor muscles of the forearm. Using floss bands as an 8-week protocol using at least two days a week had no positive effect on the isometric grip strength and the electromyography activity of the superficial flexor muscles of the forearm.

Abstract
The purpose of this study was to investigate the effect of different hip joint postures on electromyographic activity of selected lower limb muscles during squat's movement. Electromyographic activity of selected lower limb muscles of 15 healthy male students was recorded while performing a squat with neutral, 15°, 30°, 45° external and internal rotation of the hip. Friedman's nonparametric test was used to compare muscle activation at different angles of the hip rotation and the Wilcoxon test was used to determine within-group differences. The results of this study showed no significant difference in the activity of Vastus medialis (p = 0.052), Vastus lateralis (p = 0.102) and tensor fasciae lata (p = 0.193) in squat between different hip joint angles, but Significant differences were observed in gluteus medius muscle activation (p = 0.001) and biceps femoris (p = 0.015) in squat between different hip joint angles. Also, the results of this study showed that gluteus medius to tensor fascia lata activation ratio was significant in squat between different hip joint angles. squat with the external hip angles can be considered as an effective method to increase gluteus medius activation and gluteus medius to the tensor fasciae latae activation ratio. On the other hand, 45 ° external and 30 ° internal hip angles can be considered as an effective method to increase the biceps femoris activation.

Abstract
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.
