Thus, to see the improvement in decision-making skills.

Description:

The intervention of this study is nature exposure, specifically, instruct subjects to view and immerse in some nature photos due to the humanity of biophilia. The condition of mental fatigue will be induced by the Stroop task. Before the intervention or process of viewing photos, the baseline will be recorded to compare the post-test value of self-regulation and the score of decision-making skills. Moreover, the different durations of viewing photos will be implemented to identify the optimal selection.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Heart Rate Variability (HRV) will be the indicator of physiological self-regulation and measured by Polar H10 HRV belt	Before and after the intervention, the HRV will be measured to see the differences.	2 weeks
Primary	State anxiety will be the indicator of psychological self-regulation and measured by Competitive State Anxiety Inventory-2	Before and after the intervention, the state anxiety will be measured to see the differences. The arrange of scores of Competitive State Anxiety Inventory-2 is 9-36. The higher scores mean higher cognitive and physical anxiety, as well as state confidence.	2 weeks
Primary	The soccer decision-making skills will be measured by TacticUP soccer performance online system	Before and after the intervention, the decision-making skills will be measured to see the differences. The arrange of score in TacticUp is 0-100. The higher score, the better decision-making skill.	2 weeks
