We appreciate Ejima et al.‘s interest in and comments towards our article describing a 12-week randomized controlled trial of a coordination exercise program on cognitive function in obese adolescents that was conducted at a junior high school in Taipei City, Taiwan (Liu et al., 2018). Ejima et al. mentioned the apparent extraordinary effects of the interv ention on body mass index (BMI) both in the magnitude of the effects and distribution of the weight loss. On several points, we agree with Ejima et al. and in the spirit of transparency and reproducibility, we appreciate the opportunity to set the record straight about our study. We also genuinely appreciate Ejima et al.‘s time and efforts in reviewing our study and analyzing the data, and helping to uncover these mistakes. We hope this commentary aids in better understanding the findings from Liu et al. (2018) and in encouraging future effectiveness trials aimed at improving cognitive function, fitness, and BMI among obese adolescents.
