Exclusion Criteria

Do not meet 100% of the number of sprints in one or more high intensity interval training (HIIT) protocols; do not carry out any of the pre or post evaluation of HIIT; if they are absent in one of the six sessions of HIIT; present any injury or motor impairment to perform HIIT; present any infection of the upper respiratory tract during the experiment; antibiotic use within six months prior to study; regularly consume any dietary supplement composed of vitamins, minerals or bioactive compounds; do not consume any of the doses of cranberry proposed for the supplementation stage; present known allergy or intolerance to cranberry products.

Primary Outcome Measures

Name	Time	Method
It is believed that cortisol concentration will not be influenced by supplementation of Cranberry. On the other hand, after two weeks of high intensity interval training, the cranberry group will be able to reverse the effects of the accumulated training load while placebo will only show attenuation.

Secondary Outcome Measures

Name	Time	Method
It is expected that the HIIT protocols used in this study will be able to induce transient immunosuppression, associated with oxidative stress and muscle damage. It is also expected that there will be an attenuation in this immunosuppression after six training sessions.
