| Research Abstract |
The purpose of this study was to make clear the changes of saliva melatonin concentration with starting and closing of long-term camp (30 nights, 31 days.) Additionally, the purpose was to examine the relationship between physical activity and saliva melatonin concentration. The analysis samples were 11 healthy boys and girls (9-12 years old.) All investigations were carried out from July to September 2010 (camp-term was from 23 July to 22 August.) As the results, he saliva melatonin concentration in night rapidly increased with starting of long-term camp, and decreased with closing of long-term camp. In addition, the relationship between physical activity and saliva melatonin concentration showed a positive correlation.
