Exploring the Relationship Between Physical Activity and Pressure Pain Tolerance in the General Population. The...

Area of Science:

• Pain research
• Exercise science
• Public health

Background:

• Physical activity (PA) is a common recommendation for pain management and prevention.
• Previous studies suggest a link between PA and pressure pain sensitivity.

Purpose of the Study:

• To investigate the association between leisure-time PA (LTPA), occupational PA (OPA), and exercise-expended metabolic equivalent of task (MET) hours per week with pressure pain tolerance (PTol).
• To assess accelerometer-measured total counts and moderate-to-vigorous PA (MVPA) in relation to PTol.

Main Methods:

• Utilized data from the seventh Tromsø Study (2015-2016) cohort (N=21,083 for questionnaire data, N=6778 for accelerometer data).
• Employed flexible parametric survival analysis to estimate hazard ratios (HR) and 95% confidence intervals (CI).

Main Results:

• Higher LTPA and MET-hours per week were significantly associated with increased PTol (p < 0.001).
• Vigorous LTPA showed a HR of 0.63 (95% CI: 0.53, 0.73) compared to sedentary LTPA.
• Accelerometer-measured MVPA (HR: 0.91) and total activity counts (HR: 0.93) also correlated with higher PTol.
• No significant association was found for OPA with PTol.
• Stronger effects were observed in men, with no significant differences across age groups.

Conclusions:

• Increased leisure-time physical activity is associated with enhanced pressure pain tolerance in the general population.
• The findings emphasize that the context and type of physical activity (leisure vs. occupational) significantly influence pain modulation.
• These results have implications for designing targeted exercise interventions for pain management.
