Abstract: The purpose of the present study was to assess the effect of basketball-specific fatigue on the dynamic postural control of the basketball players with functional ankle instability. The subjects in this study included 28 basketball players in the Youth League in Kerman. Their ages ranged between 16 and 21 years old. Based on the results of ankle instability questionnaire (CAIT) and the medical approval, the participants were selectively divided in two groups: a group of 16 subjects with functional ankle instability and a group of 12 healthy subjects. “Basketball Movement Specific Circuit” protocol was used to induce basketball-specific fatigue, and Y test was employed to quantify postural control. Specifically, Y test was administered as a pretest and posttest at the beginning and the end of the fatigue protocol. To make sure that the intended fatigue was really induced, Borg Scale was employed and the participants were asked to express their true feeling about the intensity of the exercise at the beginning and the end of the protocol. The result of analyzing data through dependent T-test indicated that dynamic postural control significantly decreased after the induction of fatigue in both groups. In addition, running independent T-test determined that fatigue equally affected the participants of both groups. This means that the participants in the experimental group coordinated postural control mechanisms with fatigue. Based on the results of this study, it can be concluded that both healthy players and those with functional ankle instability are susceptible to ankle sprain when they feel fatigue due to defect in postural control.

Abstract: Maintaining dynamic balance in daily activities and desirable sport functions is indeed crucial. The purpose of the present study was to compare the burnout on the three directions of Y test in the basketball players with ankle instability. The subjects in this study Included 28 basketball players who were selectively divided into two groups based on the ankle instability questionnaire. first group (n=16, mean weight 71.31 ± 10.49, mean height 181.75 ± 9.16 cm, mean age 18.12 ± 1.70 years old) were functionally instable on their ankles, the second group (n=12, mean weight 73.66±9.89 kg, mean height 183.25±7.08 cm, mean age 18.41 ± 1.83 years old) were healthy basketball players.“ Basketball Movement Specific Circuit” protocol was used to achieve basketball-specific fatigue, and Y test was used to quantify postural control. To make sure that fatigue occurred, Borg scale was employed. The result of dependent T test indicated that dynamic postural control decreased after fatigue in both groups(α<0.005). In addition, the result of the one-way ANOVA demonstrated that there is a statistically significant difference between anterior and posteromedial directions in the group with functional ankle instability and between anterior and posterolateral directions in the healthy group. The results of this study showed that fatigue significantly affected the players with functional ankle instability in posteromedial direction and the healthy players in posterolateral direction.

Abstract: Zurkhaneh as one the oldest sport is include many overhead movements. The purpose of this study was comparison between ratio of strength and range of motion in internal and external rotation in the shoulder joint’s zurkhaneh athletes with Non-athletes. The subjects in this study included 29 zurkhaneh athletes with mean age (23.51±2.04) and mean years of sport history (8.75±4.47) and 30 non-athletes athletes with mean age (24.8±1.56). Data were collected through questionnaires, and subjects' strength was measured by “Hand-held dynamometer” and ROM was measured by “Leighton flexometer”(r=0.90–0.99) in both upper extremities. Data were analyzed by paired samples t-test and independent samples t-test. The results of this study showed significant degrees at internal/external rotation ROM ratio of zurkhaneh athletes than the non-athletes group (p≥0.05). some result also was found in strength ratio in internal/external rotators in this group (p≥0.001). Therefore repeated pattern of movements in the zurkhaneh sport at the long time causes imbalance in strength and range of motion shoulder joint that need to corrective exercise. It can be included due to specific demands such as repeated rotational movements in shoulder joint, they need a compensatory corrective exercises.
