Resistance Training in Adults With Obesity
- Conditions
- Overweight and Obesity
- Interventions
- Other: High-repetition resistance trainingOther: Moderate-repetition resistance training
- Registration Number
- NCT05092061
- Lead Sponsor
- Norwegian University of Science and Technology
- Brief Summary
The purpose of this project is two-fold: (1) to assess if two different resistance training protocols elicit different responses in the acute phase and (2) to assess if the same two different protocols will elicit different long-term responses on muscular strength, body composition and cardiometabolic health. The project will include 30 adults with obesity (defined as BMI ≥ 30 or abdominal obesity according to the International Diabetes Federation). In the acute phase blood lactate, heart rate, enjoyment and perceived exertion will be assessed after the two resistance training protocols. In addition, the mean 24-h blood glucose concentration after exercise will be compared between the two protocols.
For the long-term effects blood markers of cardiometabolic health, blood pressure, body composition, objectively measured physical activity and physical fitness will be assessed before and after the intervention. Also, perceived health-related quality of life will be assessed before and after the intervention.

Group Intervention Description High-repetition resistance training High-repetition resistance training The participants will undergo a full-body resistance training protocol with high repetitions (15+), low load (\<60% of 1RM), and short rest between sets (30s). Training will be undertaken three times per week. Moderate-repetition resistance training Moderate-repetition resistance training The participants will undergo a full-body resistance training protocol with moderate repetitions (6-12), moderate load (70-85% of 1RM), and moderate rest between sets (60-90s). Training will be undertaken three times per week.
