Comparing the Exercise-Induced Hypoalgesia after Aerobic Continues vs High Intensity Interval Exercise

The aim of the current study was to compare the exercise-induced hypoalgesia (EIH) due to Aerobic Rehabilitative Continues vs High Intensity Interval exercise.

Thirty-nine healthy participants (Mean ± SE age 30 ± 9.7 year, BMI 23.6 ± 2.8 kg/m2) were randomly assigned into 3 groups (13 in each) including aerobic continues exercise, high intensity interval exercise and/or control group. EIH index was recorded on before, immediately after and 30 minutes after exercise or control intervention. A mix ANOVA was used to statistically analyse the data.

The EIH index was significantly developed at all the quadriceps, biceps and upper trapezius muscle sites (p > 0.05). EIH index immediately after intermittent exercise was significantly higher than immediately after continues exercise in quadriceps muscle site (p > 0.05).

Both modes of aerobic exercise has the potential to stimulate the EIH in the body at both the local and central level. The findings on muscular pain received during the exercise and EIH induced by different modes of exercise demonstratethat pain induced by exercise training is less likely to act as a stimulation for EIH rather than other characteristics of exercise training. Findings of this study has the potential to be used by pain relief therapists specially those who are interested in designing acute exercise trainings to be used as alternative pain relief therapy.
