Treatment and study plan

Phillips Energy Light HF3319

Device

Exposure to Light administered with Phillips Energy Light HF3319.

Primary outcomes

  1. Mean power output in watts

    Time frame: Power output during the first 30 minute time-trial on a bicycle ergometer.

Secondary outcomes

  1. Subjective sleepiness

    Time frame: 1 minute after the light exposure vs. 1 minute before the light exposure in the first time trial

    Subjective sleepiness will be measured with the Multidimensional Mood Questionnaire (Category "Wakefulness - Sleepiness")

  2. Subjective Mood

    Time frame: 1 minute after the light exposure vs. 1 minute before the light exposure in the first time trial

    Subjective Mood measured with the Multidimensional Mood Questionnaire (Category "Good Mood - Bad Mood")
