ACUTE EFFECTS OF DIFFERENT INTENSITY OF EXERCISE IN THE IMUNE PROFILE IN OBESE
Obesity; High Intensity Interval Training; Immunoglobulin A; Upper Respiratory Tract Infections.
Objective: The aim of this study was to compare the acute effects of high-intensity interval exercise (HIIE) and moderate-intensity continuous exercise (MICE) on salivary immunoglobulin A (IgA) levels and upper respiratory tract infections symptoms in obese males. Methods: Eight obese participants were submitted into two experimental sessions with a week interval in a randomized order: 1) HIIE: 10 x 60-s at 90% of peak velocity reached in the exercise test interspersed by 60 s of active recovery 30% of peak velocity; 2) MICE: 20 min at 50% of Heart Rate Reserve. Was analized IgA before, post and 1 hour post exercise and a Upper Respiratory Symptom Survey (URSS) was applied on exercise day, 24 and 48 hours post session. Partial results: There was no change in Upper Respiratory Symptom hunger after MICE or HIIE session (P>0,05). Conclusion: A single session of HIIE or MICE during around 20 minutes didn’t increase the Upper Respiratory Symptom after 24 and 48 hours after exercise.
