CHRONIC DISEASES
Thirty-six young and healthy men participated in this study, which was approved by the ethics committee of Kyoto Prefectural University (No. 2017–146). All participants provided written informed consent. None of the participants suffered from current (at the time of the study) or prior chronic diseases or had a history of smoking. Furthermore, none of the participants were using any medication or supplements at the time of the study or habituated to regular exercise. The participants were randomly divided into placebo and matcha groups, and body composition parameters—body weight, body fat, muscle mass, and body mass index (BMI)—were measured using bioelectrical impedance analysis (InBody430; InBody Co., Ltd., Seoul, Korea).
