The Effect of a Single Session of Aerobic or Resistance Exercise on Salivary Lipid Profile

Background: Exercise and physical activity is an effective way for maintaining health by modifying lipid profile. Many studies reported that even a single session of exercise could affect blood lipid profile. Nowadays, saliva sampling is an effective and noninvasive method in disease diagnosis and monitoring health. Based on the results, there is a significant and positive association between saliva and blood lipid values. Objectives: Our aim was to assess acute effects of aerobic and resistance exercise on salivary lipid profile. Materials and Methods: In this randomized clinical trial study, forty-five non-athlete women (18-35 years old, 18.5 ≤ BMI ≤ 25) were put in three groups (aerobic, resistance and control). Aerobic group program consisted of 30 minutes of aerobic exercise at 60-75% maximum heart rate (MHR) intensity and resistance group performed five resistance exercises at intensity of 75% 2-RM. Salivary Lipid profile was measured after 12 hours of fasting at 8 a.m. and immediately after exercise. Results: One single session of aerobic and resistance did not induce significant change in salivary lipid profile. However, a significant difference was observed between changes in aerobic and resistance groups (P=0.03). Conclusions: This study suggested that one session of aerobic and resistance exercise with moderate intensity did not change salivary lipid profile.
