週1回90分のスポーツ実技は大学生の粘膜免疫向上に寄与する

  University students have the opportunity to exercise once a week through sports courses. Practical sports courses at universities provide valuable opportunities for university students to exercise. Immunity is said to change with exercise. Therefore, sports courses may assist university students in strengthening their immunity. This research aimed to clarify whether the immunity of university students will improve by engaging in 90 minutes of sports once a week for half a semester. The subjects were 17 students in a practical sports course. Saliva samples were collected before and after 4th and 14th 90-minute sports practice classes, twice in total. Secretory Immunoglobulin A (sIgA), salivary cortisol, and salivary amylase levels were measured from the saliva samples. Ratings of perceived exertion (RPE) were measured at every sports practice.

  SIgA was significantly increased after the class compared to before the class (p < 0.05). However, salivary cortisol, and salivary amylase levels showed no significant difference (n.s.). The RPE of the sports practical skills class during survey period was 11.3 ± 2.7.

  The results of this study showed that a 90-minute sports practice course improves the immune competence of students. Although the regimen did not meet the criteria for exercise habits, it has been shown that sports contribute to maintaining and improving the health of university students.
