Abstract
Aim and Background: Ankle is one of the most common sports injuries caused by direct collisions with opposing players or the ground, tackles from inside and outside, jumping and landing. Among these injuries, external ankle sprain is one of the most common injuries that is associated with ankle instability. The purpose of this research is to compare balance exercises and hopping on the proprioception of athletes with functional ankle instability.
Materials and methods: 30 athletes with functional instability of the ankle were randomly divided into 2 study groups of the clinical trial. The first group included athletes with functional ankle instability doing hopping exercises (15 people), the second group included athletes with functional ankle instability doing balance exercises (15 people). At first, the proprioception of their ankle joint was evaluated with the help of photography, and then they did exercises for 6 weeks, and at the end, the proprioception of the ankle joint was evaluated again. SPSS version 20 software was used to analyze the data of this research.
Results: The results showed that balance and hopping exercises significantly reduced the absolute error of ankle dorsiflexion and plantarflexion reconstruction (p<0.05). Also, there is a significant difference between the two groups of balance exercises and hopping (p<0.05).
Conclusion: The results of the present study showed that balance and hopping exercises improved the proprioception of the ankle joint in athletes with functional instability of the ankle, and hopping exercises are more effective than balance exercises.

Abstract
The purpose of present study was to examine the effects of short time static and dynamic stretching of muscles on kinematics variability of lower extremity in healthy active males during cycling. 15 physical education and sport sciences male students from Kharazmi University voluntarily participated in this study. Subjects referred to the laboratory during two days, with 48 hours intervals between each sessions, and lower extremity kinematics data were collected from 30 pedaling cycle on the stationary cycle in 70 RPM in situation of without stretching, after 2, 5, and 10 minutes post stretching by means of motion analysis camera in 50 Hz frequency. Hip, knee and ankle joints angular displacement and velocity were extracted for constructing time series and variability calculation. Results of repeated measure ANOVA did not show any significant differences in angular displacement and velocity variability in hip, knee and ankle joints after 2, 5, and 10 minutes post stretching (P>0.05). Regarding results, probably it can be use static and dynamic stretching in warm up programs before cycling or rehabilitation on stationary cycle.
