简要总结
It has been shown that 5-HTP stimulates cortisol levels in plasma and saliva. Similarly, it has been shown that intense exercise stimulates an increase in plasma and salivary cortisol levels. The purpose of this study is to examine the combined effects of 5-HTP + intense exercise on plasma and salivary cortisol levels.

研究组 & 干预措施
Placebo
For these visit subjects will ingest placebo (Sugar pill) capsule 2 hours before reporting to the laboratory.

结局指标
主要结局
Change in plasma cortisol from baseline to 20 minutes post
时间窗: baseline, 20 min
Plasma cortisol will be assessed at baseline and 20 min post exercise and compared to baseline, and compared between treatments: 5-HTP vs placebo visit. The interventions are acute ( 1 dose, 1 day), for 5-HTP and for placebo, there is no follow up. The interventions are at least 1 week apart. For a given subject, the estimated time for study completion for the 2 treatments is 10 to 30 days
次要结局
- Change in plasma cortisol from baseline to 5 minutes post(baseline, 5 minutes)
