Effect of a physical activity intervention on suPAR levels: A randomized controlled trial

Area of Science:

• Biochemistry
• Exercise Physiology
• Immunology

Background:

• Soluble urokinase-type plasminogen activator receptor (suPAR) is an emerging inflammatory marker linked to lifestyle diseases and mortality.
• Previous research indicates suPAR's association with various health conditions, but its modulation by physical activity remains understudied in controlled settings.

Purpose of the Study:

• To investigate the effect of a supervised exercise intervention on suPAR levels in physically inactive immigrant men.
• To determine if regular physical activity can reduce suPAR levels, a marker of inflammation.

Main Methods:

• A randomized controlled trial involving physically inactive Pakistani immigrant men in Norway.
• Participants were assigned to either a supervised group exercise intervention or a control group for 5 months.
• Blood samples were analyzed for suPAR and C-reactive protein (CRP) levels at baseline and post-intervention, with linear regression used for analysis.

Main Results:

• Both the intervention and control groups showed a significant increase in suPAR levels from baseline to post-test.
• Obesity and smoking were identified as factors associated with higher baseline suPAR levels.
• No significant difference in the change of suPAR levels was observed between the exercise intervention group and the control group.

Conclusions:

• Regular supervised exercise did not significantly alter suPAR levels compared to a control group.
• The findings suggest that suPAR may primarily reflect underlying harmful inflammatory processes associated with disease development.
• suPAR's role as a modifiable risk factor through exercise needs further investigation.
