Resistance Training in Adults With Obesity

Acute and Chronic Effects of Two Different Types of Resistance Training on Cardiometabolic Health in Adults With Obesity

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.

Inclusion Criteria:

• Obesity (BMI ≥ 30) or
• Central obesity (defined according to the International Diabetes Federation).

Exclusion Criteria:

• Unstable angina
• recent cardiac infarction (last 4 weeks)
• uncompensated heart failure
• severe valvular illness
• pulmonary disease
• uncontrolled hypertension
• kidney failure
• orthopaedic/neurological limitations
• cardiomyopathy
• planned operations during the research period
• participation in a parallel study
