Effect of different intensity aerobic activity on total protein concentration in saliva
The biochemical composition of saliva in order to study effects of physical activity has been considered by many researchers. The aim of this study has been effect of different intensity aerobic activity on salivary total protein concentration. In this study, 10 male non-athletes academic (with an average height of 172/9 ± 4/25 cm, weight 67/8 ± 0/08 kg, body fat percentage, 15/98 ± 3/85, VO2max, 38/49 ± 6/43 ml/kg/min ,age 23/2 ± 2/35 years) randomly selected. For the measurement of maximal oxygen uptake, subjects performed an incremental continuous protocol on treadmill. In The main test, subjects did activity in three separate sessions for at least 7 days between them and at 2.30 pm. In order to compare the mean changes of total salivary protein concentrations between the three modes of activities used ANOVA test. The results indicated that the concentration of total protein in each exercise intensity decreased. That might parasympathetic nerve activity lead to increase in salivary fluid and ultimately a reduction in the total protein concentration. However, several factors moreover intensity of activity can also influence in the factor studied in this research.
