Abstract

The hypoalgesic effects of acute exercise are well documented. However, the effect of chronic exercise training on pain sensitivity is largely unknown.

PURPOSE:

To examine the effect of aerobic exercise training on pain sensitivity in healthy individuals.

METHODS:

Pressure pain threshold, ischemic pain tolerance and pain ratings during ischemia were assessed in 24 participants before and after 6 weeks of structured aerobic exercise training (n=12) or following 6 weeks of usual physical activity (n=12). The exercise training regimen consisted of cycling 3 times per week for 30 min at 75% of maximal oxygen consumption reserve.

RESULTS:

Significant increases in aerobic fitness (p = 0.004) and ischemic pain tolerance (p = 0.036) were seen in the exercise group following training, while pressure pain threshold and pain ratings during ischemia were unchanged (p > 0.2). No change in aerobic fitness (p > 0.1) or pain sensitivity (p > 0.1) was observed in the control group.

CONCLUSION:

Moderate-vigorous intensity aerobic exercise training increases ischemic pain tolerance in healthy individuals.
