en Effect of Processed Soybeans (Tofu and Tempeh) Consumption, and Exercise on Upper Respiratory Tract Immunity ایمنی شناسی Immunology مقالات اصلی Original Article <div style="text-align: justify;">Background: IgA is widely used as Upper Respiratory Tract Infection (URTI) risk marker, as a lower concentration in sIgA indicates a higher incidence of URTI. This study aimed to investigate the effect of different types of exercise; combined with Tempeh consumption in increasing sIgA concentration in saliva sample. Methods: 19 sedentary male subjects aged 20-23 were recruited and assigned into 2 groups based on the exercise type, endurance (n=9), and resistance (n=10). These subjects underwent 2 weeks of Tofu and Tempeh consumption, then were assigned to do exercises based on their groups. Results: This study showed an increased mean value of sIgA concentrations in the endurance group; the baseline value, after food treatment, and after food and exercise treatment were 71.726 ng/mL, 73.266 ng/mL, and 73.921 ng/mL, respectively for Tofu treatment; and 71.726 ng/mL, 73.723 ng/mL, and 75.075 ng/mL, respectively for Tempeh treatment. While in the resistance group, there was also an increase in the mean value of sIgA concentrations; baseline, after food treatment, and after food and exercise treatments were 70.123 ng/mL, 71.801 ng/mL, and 74.430 ng/mL, respectively for Tofu treatment; and 70.123 ng/mL, 72.397 ng/mL, and 77.216 ng/mL, respectively for Tempeh treatment. These results indicated that combining both Tempeh consumption and moderate intensity resistance exercise was more effective to increase sIgA concentration. Conclusions: This study showed that combining moderate intensity resistance exercise with consumption of 200 gr Tempeh for 2 weeks was more effective in increasing sIgA concentration; compared to endurance exercise and Tofu consumption.</div> : Exercise, IgA, Paraprobiotics, Tempeh, Upper Respiratory Tract Infection (URTI) 720 729 http://rbmb.net/browse.php?a_code=A-10-1106-2&slc_lang=en&sid=1 Albert Ananta 100319475328460016876 100319475328460016876 No Department of Biotechnology, Faculty of Biotechnology, Atma Jaya Catholic University of Indonesia, Jakarta 12930, Indonesia Rendy Dijaya 100319475328460016877 100319475328460016877 No Nutrifood Research Center, PT.
