Effects of Nature Exposure Intervention on Soccer Performance Among Mentally Fatigued University Players

The current study is going to investigate the nature exposure intervention on the ability of self-regulation and decision-making skills among mentally fatigued soccer players. The subjects will be instructed to view some nature photos, which can facilitate the recovering process for directed attention and the ability of self-regulation. Thus, to see the improvement in decision-making skills.

About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • The selection of the participants will be every position without the goalkeeper. The age of them will be at 18-24 years. Only male players will be selected. Players should have at least played from the senior school and have 3 years' training experience.

Exclusion criteria

  • The study will exclude color blindness, for the Stroop task will involve color. Self-reports should be free of any known disease or sleep disorder and not currently taking any medication.

Treatment and study plan

Nature exposure

Other

Nature exposure has different ways, such as walk in the real nature environment; viewing nature photos. Two main reasons make this study will not use the real nature environment: (1) the limitation of time before or amid the soccer competition; (2) the pandemic situation does not allow people go outside as frequently as before. Therefore, the current study will select some nature photos, which are restorative environments and can restore directed attention to counteract mental fatigue.

Primary outcomes

  1. Heart Rate Variability (HRV) will be the indicator of physiological self-regulation and measured by Polar H10 HRV belt

    Time frame: 2 weeks

    Before and after the intervention, the HRV will be measured to see the differences.

  2. State anxiety will be the indicator of psychological self-regulation and measured by Competitive State Anxiety Inventory-2

    Time frame: 2 weeks

    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.

  3. The soccer decision-making skills will be measured by TacticUP soccer performance online system

    Time frame: 2 weeks

    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.
