Strong Support

In adults with psoriatic arthritis, 11 weeks of high-intensity interval training was linked to small decreases in body fat percentage and body mass index, though these changes were not statistically significant. The data suggest that fat around the midsection may respond more than overall body fat to this type of exercise.

Effect of high-intensity interval training on cardiovascular disease risk factors and body composition in psoriatic arthritis: a randomised controlled trial

Randomized Controlled Trial
Human
2018

This study found that doing short bursts of intense exercise for 11 weeks helped people with psoriatic arthritis lose a little fat around their middle, even if their overall weight didn’t change much. So yes, the exercise seems to help, especially in the belly area.

Similar Assertions

In adults with psoriatic arthritis, 11 weeks of high-intensity interval training led to a small but measurable decrease in fat around the torso, and this reduction was still present, though smaller, after nine months.

For adults with psoriatic arthritis, high-intensity interval training does not lead to higher levels of inflammation or joint swelling as measured by standard clinical markers.

Adults with psoriatic arthritis who do high-intensity interval training three times a week for 11 weeks show a measurable improvement in their cardiorespiratory fitness, measured as increased VO2max, which remains elevated after nine months and is linked to lower cardiovascular risk.
