Brief summary: The ankle joint is commonly used and also stricken by high loads and injuries in sports. One technique in emphasis is cryotherapy, a physiotherapeutical intervention characterized by the use of low temperatures for tissue trauma's rehabilitation. Several studies analysed the effects of cryotherapy and brought important results related to pain and strength reduction, also to muscle contraction speed reduction. Although, considering the risk-benefit from de intervention it's pertinent to observe the presence of deleterious effects, especially the ones that impact on motor function. This scenario has been brought by scientists and currently the main gap from this theme resides on the repercussions of the technique application on functional answers

Detailed description: Eighty participants will receive control (rest) and the experimental condition (cryotherapy), with an interval of 48 hours. The intervention group will undergo: i) assessment, ii) 20 minutes of cryotherapy, iii) reassessment, iv) 20 minutes of rest and v) reassessment, while the control group remains at rest for 20 minutes. Assessments will be composed of ankle function by the modified star excursion balance test, muscle tone by the myoton pro, skin temperature by a thermographic camera, thermic comfort, perception of balance and beliefs in cryotherapy. Data will be described using mean and standard deviation and compared by Mixed ANOVA (time x intervention) with post Bonferroni tests, with significance level of 0.05.
