TL;DR

ChatGPT outperformed personal trainers in answering common exercise training questions, with higher ratings in scientific correctness, comprehensibility, and actionability across the majority of questions evaluated.

Key Findings

ChatGPT outperformed personal trainers in six of nine exercise training questions on overall score.

  • Nine currently active level 4 (EQF) personal trainers submitted their most frequently asked exercise training questions along with their own answers.
  • The same questions were posed to ChatGPT version 3.5.
  • Responses were evaluated by 18 personal trainers and 9 topic experts.
  • None of the responses from personal trainers were rated higher than those from ChatGPT for any question or metric.
  • Group means were compared using permutation tests.

ChatGPT received higher ratings than personal trainers in scientific correctness for five of nine questions.

  • Scientific correctness was one of three criteria used to evaluate responses.
  • Scores for each criterion were averaged into an overall score.
  • Personal trainers did not score higher than ChatGPT on scientific correctness for any of the nine questions.

ChatGPT received higher comprehensibility ratings than personal trainers in six of nine questions.

  • Comprehensibility was one of three evaluation criteria alongside scientific correctness and actionability.
  • Evaluators included both 18 personal trainers and 9 topic experts.
  • Personal trainers did not outscore ChatGPT on comprehensibility for any question.

ChatGPT received higher actionability ratings than personal trainers in five of nine questions.

  • Actionability was one of three criteria used to rate responses.
