It’s my honor to be one of translators for the remarkable exercise science book NSCA’s Essentials of Sport Science in traditional Chinese version. As we all know, the sport scientist’s role is central throughout, including knowledge of training theory, determining and evaluating key performance indicators, conducting athlete monitoring and assessments, and managing and disseminating complex performance information. In addition, the integration of scientific methodology and applied technical skills will guide sport scientists in drawing conclusions aimed at supporting or re-envisioning training methods, contributing towards competition strategy, and improving athletes’ overall readiness and performance. Due to those benefits mentioned above, as an exercise science and sport science professional, it’s the indispensable book that you should have.
