  Purpose

The human adipose and muscle -tissue produce and release a number of bioactive proteins which contributes to the chronic low grade of inflammatory status which is associated with obesity and plays an important role in the pathogenesis of type 2 diabetes and cardiovascular diseases.

Study 1: Our aim is to investigate if exercise has independent and additive effects in combination with diet-induced weight loss on circulating levels of inflammatory markers and mRNA levels in subcutaneous adipose tissue (SAT) and skeletal muscle tissue (SM.

Study 2: Our aim is to investigate whether gender and weight status plays a role in the metabolic response during two hours of acute exercise

Primary Outcome Measures:
  • Changes in inflammatory markers as Adiponectin, MCP-1, Interleukin-6 and CRP. Moreover changes in body composition quantified with MRI [ Time Frame: 8 weeks and 12 weeks ] [ Designated as safety issue: No ]
  • Change in Interleukin-6 and other inflammatory markers in plasma, adipose tissue and muscle tissue [ Time Frame: 60, 120 240 minutes ] [ Designated as safety issue: No ]

Estimated Enrollment: 100
Study Start Date: September 2006
Estimated Study Completion Date: March 2009
Estimated Primary Completion Date: June 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: EXO
Exercise-only (EXO-12 weeks of regular supervised exercise without diet restriction),
 Behavioral: Exercise-only (EXO-12 weeks of regular supervised exercise without diet restriction)
The exercise intervention for subjects in the EXO consisted of supervised aerobic exercise three times per week with a duration of 60 -75 minutes pr. training session, with an estimated energy expenditure of 500-600 kcal per session. The subjects could choose between different modes of exercise; stationary bicycling, jogging on a treadmill or stair stepping.
Active Comparator: DIO
Diet-only (DIO-8 weeks of very low energy diet (VLED 600 kcal/d) followed by 4 weeks weight maintenance diet)
 Behavioral: Diet-only (DIO-8 weeks of very low energy diet (VLED 600 kcal/d) followed by 4 weeks weight maintenance diet
Subjects in the DIO group were prescribed a liquid VLED(Nupo, Copenhagen) of respectively 600 and 800 kcal pr. day (proteins 41 g, carbohydrates 29 g, fat 5.6 g. pr 100 gram) for eight weeks followed by a weight maintenance diet for four weeks.
Active Comparator: DEX
Diet+exercise (DEX-8 weeks VLED 800 kcal/d + a four weeks weight maintenance diet combined with regular supervised exercise throughout the 12 weeks).
 Behavioral: Diet+exercise (DEX-8 weeks VLED 800 kcal/d + a four weeks weight maintenance diet combined with regular supervised exercise throughout the 12 weeks).
The exercise intervention for subjects in the DEX group consisted of supervised aerobic exercise three times per week with a duration of 60 -75 minutes pr. training session, with an estimated energy expenditure of 500-600 kcal per session
