Comparative effectiveness of exercise interventions for primary dysmenorrhea: a systematic review and network meta-analysis.

Menstrual cramps from primary dysmenorrhea are common, and exercise is often suggested as a treatment, but it has been unclear which type of exercise actually helps most. This network meta-analysis pooled 49 randomized trials comparing six exercise categories, including resistance, aerobic, stretching, core-strengthening, mind-body, and multi-component programs, against control groups. Across the pooled evidence, all six exercise types were associated with reduced menstrual pain compared with controls, with resistance exercise and multi-component exercise showing the strongest statistically significant reductions in pain intensity. Different exercise types appeared better suited to different outcomes, such as symptom relief versus pain duration, and the benefits varied depending on how long and how often people trained.

This is interesting because it suggests exercise dosage and type both matter, but the analysis pools very different small trials, so the certainty behind individual comparisons is limited.

If you deal with painful periods, you may have heard that exercise can help. This study looked at many previous trials testing different kinds of exercise, like resistance training, aerobic workouts, stretching, core exercises, mind-body practices such as yoga, and combined programs, to see which worked best for menstrual pain. The combined results found that all these exercise types were linked to less menstrual pain compared with not exercising.

Resistance exercise and programs combining multiple exercise types showed the clearest reductions in pain intensity, while other types seemed to help more with symptoms or how long pain lasted. Training for four to eight weeks was linked to meaningful pain relief across exercise types, and effects differed depending on how often and how long people exercised. Because this is based on pooling many smaller studies that used different exercise programs and measurements, the findings give a general direction rather than a precise answer about the single best routine for any individual.

This network meta-analysis pooled 49 randomized controlled trials (3,129 participants; 1,640 receiving exercise interventions, 1,489 controls) comparing six exercise modalities for primary dysmenorrhea, using SUCRA rankings within a Bayesian framework. All exercise categories, resistance, aerobic, stretching, core-strengthening, mind-body, and multi-component, were associated with reduced menstrual pain versus controls, but statistically significant reductions in pain intensity were specifically reported for resistance and multi-component exercise. Subgroup analyses indicated modality-specific effects: multi-component and stretching exercise ranked best for menstrual symptoms, core-strengthening and multi-component ranked best for reducing pain duration, and dosage patterns varied by modality, with resistance exercise showing best efficacy beyond 8 weeks and within 30-minute sessions, while multi-component exercise performed best with longer sessions or lower weekly frequency (1 to 3 sessions). Given the breadth of exercise types, dosing parameters, and outcome measures synthesized across 49 heterogeneous trials, the network comparisons should be interpreted as hypothesis-generating rather than definitive; the abstract does not report certainty ratings, risk-of-bias summaries, or heterogeneity statistics, limiting confidence in the precise ranking of one modality over another for specific outcomes.
