Sažetak
Objective: To examine how exercise-induced analgesia is affected by the duration and intensity of aerobic exercise. Design: Repeated-measures design. Setting: Exercise science laboratory. Participants: Convenience sample of 12 healthy male and female volunteers (mean age
standard deviation, 32
9y). Interventions: Pain ratings were assessed before and at 5 and 30 minutes after treadmill exercise of 10 minutes at 75% maximal oxygen uptake (V˙ O2max), 30 minutes at 50% V˙ O2max, and 30 minutes at 75% V˙ O2max (randomized order and no less than 48h between each bout). Main Outcome Measures: Pain ratings were measured on a visual analog scale at 10-second intervals during a 2-minute pressure-pain stimulus to the nondominant index finger. Results: Pain ratings were significantly decreased (P.05) from pre-exercise values 5 minutes after 30 minutes of exercise at 75% V˙ O2max but returned toward baseline by 30 minutes after exercise. There were no significant changes in pain ratings after 10 minutes of exercise or after exercise at 50% V˙ O2max. Conclusions: There are thresholds for both the intensity (50% V˙ O2max) and duration (10min) of exercise required to elicit exercise analgesia.
