The Effect of Short- Term use of Cold Spray on Strength and Ankle Joint Position Sense in Professional Wrestler

The aim of this study was to investigate the effect of a short period of cryotherapy on strength and ankle position sense in professional wrestlers.
In this semi experimental research, fourteen Professional wrestlers (age 24.2.5 years old, and weight 74.1.2 kg) that they all had at least five years training experience with provincial and national championships participated in this study. Manual Muscle Tester was used to measure the strength of dorsi and plantar flexor muscle before and after cryotherapy that was Simultaneously applied on medial-lateral of the ankle, with distance 30 cm. Meanwhile, performance accuracy of the ankle joint was assessed via Electrogoniometer that measure the active and passive Regeneration error of ten and twenty angles of dorsi and plantar flexion respectively, before and after cold application. Shapiro-Wilk test was used to check the normality distribution, using a paired t- test to compare variables with a significant level of (p≤0.05).
The results showed that short-term local cooling by using cold spray does not change significantly the strength of dorsi and plantar flexor muscles and ankle joint position sense of professional wrestlers in active and passive form.
According to the result, it seems that applied cryotherapy only effects on skin receptor and it does not affect the body's protective factors, such as muscle spindle and Golgi organelles, and inner receptors that play a main role in the tension and of joint position sense.
