The Effect of Eight Weeks of 10, 20, and 30 Seconds Exercise Training on the Levels of Antimicrobial Factors In the Saliva of Obese Adolescent Boys

The role of the immune system and inflammation in controlling metabolic diseases such as insulin resistance, type 2 diabetes, obesity and overweight is well established. Also, physical activity controls and prevents the occurrence of metabolic diseases, which has anti-inflammatory and anti-oxidative effects. The aim of the present study was to study the effect of eight weeks of 10, 20, 30 seconds exercise training on the levels of antimicrobial factors in the saliva of obese adolescent boys.

32 male students voluntarily participated in the present study and were randomly assigned to four groups: 1) obese aerobic exercise, 2) normal weight aerobic exercise, 3) obese control without exercise, and 4) normal weight control without exercise. The criteria for the obese group was a BMI above 25. Anthropometric indices of height, weight and body mass index were measured exactly. Before and after eight weeks of practice, Shatell-Run standard test was performed. Salivary samples of lysozyme, lactoferrin, lactate and C-reactive protein concentrations were taken after eight weeks of training with a frequency of three sessions per week with an intensity of 30 to 90% of maximum aerobic power. Using analysis of covariance, variables with a significance level of less than (P≤0.05) were included in the analysis.

The results showed a significant increase in salivary levels of lactoferrin (P=0.001), lysozyme (P=0.003), lactate (P=0.001), and C-reactive protein (P=0.006). There are more obese students than people of normal weight (Youth body mass index criterion)

The increased response of some antibacterial and inflammatory salivary proteins after eight weeks of 10-20-30 sports training following exhaustive activity may be due to the acute response of the immune system.
