Assessment

Primary outcomes

In this experiment, physical examinations: subjective fatigue degree, blood pressure, pulse and flicker level of the examinees are measured, before the intake of chocolate. The examinees take in chocolate before learning start. After one hour learning, the same physical examinations of examinees are measured. After 30 minutes later, the same physical examinations are measured again. The examinees take two types of chocolate with different content of cacao polyphenol and perform two times of similar experiments. In this study, comparing the differences of fatigue level in each experiment, the influence of cacao polyphenol of chocolate is analyzed.
