About

The goal of this clinical trial is to compare the degree of effort during a resistance exercise session on blood glucose levels in individuals with prediabetes or type 2 diabetes mellitus. The main questions it aims to answer are:

  • Do individuals with prediabetes or type 2 diabetes mellitus need to perform resistance exercise with a high degree of effort for their blood glucose to improve?
  • How do they feel (their enjoyment, discomfort) after the sessions with different degrees of effort?

Participants will perform 3 situations separated by at least 4 days, after being familiarized with all exercises and procedures:

  • One control day, when they will not exercise;
  • A high-effort resistance exercise session;
  • A low-effort resistance exercise session Researchers will measure blood glucose levels and psychological responses after these situations to see if the effort was important for the improvement of their blood glucose and how effort affected the way they felt after each situation.
