Keywords: Exercise; salivary alpha-amylases; sympathetic nervous system

Objective: In this study, salivary alpha-amylase activity was measured to elaborate on sympathetic nervous system activity in athletes.

Materials and Methods: Six male subjects between 18-21 years of age participated in two 4-hour long trials (exercise and contr ol) planned in a random crossover design. In the exercise trial, subjects ran for 105 minutes at 50% of maximum oxygen uptake and for 15 minutes at 75% of maximum oxygen uptake followed by a 120 min rest period. In the control trial, subjects rested for 4 h. Statistical analysis of the data was performed by two-way repeated measures analysis of variance during 4 hours of monitoring.

Results: Two-way repeated measures analysis showed a significant effect of time (Time; F=20.332, p<0.001), effect of trial (Trial; F=52.99, p<0.001) and effect of time and trial interaction (Trial & Time; F=15.244, p<0.001) for salivary alpha-amylase activity.

Conclusion: The fact that acute long-term aerobic exercise activates sympathetic nervous system was demonstrated by the algorithm of salivary alpha amylase activity increase in athletes.
