Abstract |
Background and Aim: The term, “exercise-induced gastrointestinal syndrome”, has recently been introduced to describe a complex array of normal physiological responses to exercise that perturbs and compromises gastrointestinal integrity and function. Thus, because of the ambiguities about the exercise-induced gastrointestinal disorders, especially high-intensity intermittent exercise (HIIT) the present study investigated to compare the responses of Immunoglobulin M and some gastrointestinal disorders markers to one-session continuous moderate training and high-intensity interval training (MICT & HIIT) in female athletes. Methods: To investigate the response of indicators related to the gastrointestinal syndrome, in a quasi-experimental design, thirty female athletes participated in three equal groups (MICT: n=10, HIIT: n=10, and control: n=10). MICT consisted of 60 minutes’ submaximal steady-state running at 70% heart rate reserve, and HIIT athletes completed an acute bout of running (eighteen 400 m runs at maximum speed). Blood samples were collected before, immediately, and two h after the exercise protocols. I-FABP, zonulin, LPS, and IgM amounts were measured using ELISA methods. All data expressed as mean±SD and analyzed using repeated-measures analysis of variance at α≤0.05. Results: Levels of I-FABP, LPS, and zonulin increased significantly (p<0.05) after MICT and HIIT protocols, whereas Ig-M concentration decreased significantly (p<0.05). However, the significant difference between acute decreased IgM responses and increased I-FABP, LPS, and zonulin responses to one-session MICT and HIIT protocols were not observed (p>0.05). Conclusion: Based on the results of the present study, it can conclude that the acute gastrointestinal (GI) responses in female athletes to one-session MICT and HIIT protocols may similarly increase GI permeability, intestinal damage, and endotoxemia. |
