- Registration Number
- NCT06208189
- Lead Sponsor
- University of New Mexico
- Brief Summary
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.

- Arm && Interventions
Group Intervention Description high-effort session High-effort session Participants will perform sets with as many repetitions they can each set. low-effort session Low-effort session Participants will perform sets with half of the anticipated number of repetitions of the high-effort session. Control session Control The control session all procedures will be identical to the high-effort session.
- Primary Outcome Measures
Name Time Method Prevalence of hypoglycemia For 6 hours during the nocturnal period (12 am - 6 am) of each situation (arm) of the study Time of glucose concentrations \<70 mg/dL (measured in minutes)
Time in range For 6 hours during the nocturnal period (12 am - 6 am) of each situation (arm) of the study Time of glucose concentration between 70 and 180 mg/dL (measured in minutes)
Glucose concentration For 6 hours during the nocturnal period (12 am - 6 am) of each situation (arm) of the study Average glucose concentration (measured in milligrams per deciliter of blood, with a continuous glucose monitoring device)
Prevalence of hyperglycemia For 6 hours during the nocturnal period (12 am - 6 am) of each situation (arm) of the study Time of glucose concentrations \>180 mg/dL (measured in minutes)
- Secondary Outcome Measures
Name Time Method Rating of Discomfort scale Before and 5 minutes after the resistance exercise sessions. Discrete scale from 0 to 100, where higher scores mean more discomfort.
Resistance Training Intensity by the Omni Perceived Exertion Scale After each set of each exercise performed. Discrete scale from 0 to 10, where higher values mean more perceived exertion.
Feeling scale Before and immediately after the resistance exercise sessions. Discrete scale from -5 to +5, where higher values mean more positive feelings.
Physical Activity Enjoyment Scale Immediately after the resistance exercise sessions. Scale composed of 18 items, with scores from 1 to 7 each (total score from 18 to 126). After analysis, higher scores mean higher enjoyment.
Self-efficacy scale Immediately after the resistance exercise sessions. Scale composed of 8 questions, with discrete options from 0 to 100%. Higher scores mean higher self-efficacy.
Session rating of perceived exertion 5 minutes after the resistance exercise sessions. Discrete scale from 0 to 10, where higher values mean more perceived exertion.
