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, fortyfive nonathlete women (1835 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 6075% maximum heart rate (mhr) intensity and resistance group performed five resistance exercises at intensity of 75% 2rm. 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.
