Purpose: Electrogastrogram might be altered by the autonomic nervous balance which would be changed by military training.

Methods: Twenty freshmen were chosen randomly and had tests before, during or after the military training with Medtronic Polygram NetTM. The indexes were analysed automatically which include dominant frequency and power and percentage of normal gastric slow wave at fast or postprandial (pre-DF, pre-DP, pre-N%, pos-DF, pos-DP, pos-N%).

Results: 1. Pos-DP was higher than pre-DP before training; there was no difference between pre-DP and pos-DP during training and after training (P>0.05). (Table 1) 2. Pos-DF was higher than pre-DF during and after training (3.07±0.2 vs. 2.87±0.2, P<0.001 and 3.08±0.2 vs. 2.9±0.3, P<0.001). 3. Both pos-DF during and after training were higher than that before training. (Table 2) 4. There was no difference of N% between each group and between different training periods (P>0.05).

Conclusion: Military training increases pos-DF compensatorily to overcome the disadvantage of unchanged pos-DP. It has no impact on N%.
