Exercise is often recommended in migraine treatment, but strenuous physical activity is also reported as a migraine trigger. The main aim of this study was to evaluate whether migraine can be triggered by a maximal exercise test, using a prospective test-retest method. A secondary aim was to compare the participants who responded to the maximal exercise test with a migraine attack with those who did not suffer a migraine attack after the test.
A total of 19 patients reporting exercise as a potential trigger for their migraines were included in the study. After a baseline period of 1 month with measurements of migraine frequency, a cycle ergometer test until exhaustion was used twice on each patient.
A total of 14 patients were test-retested, and of these, 3 reported migraine following both tests, 5 after one of the tests, and 6 did not report migraine after either test. We observed a higher risk of migraine after 1 or 2 tests in patients with a higher baseline migraine frequency (p = 0.036).
In conclusion, the study showed that although maximal aerobic exercise can trigger migraine attacks, it does not always provoke an attack even in those who report exercise as a migraine trigger.
运动常被推荐用于偏头痛治疗，但也有报道称剧烈体育活动是偏头痛的诱发因素。本研究的主要目的是采用前瞻性重测法评估最大运动试验是否会诱发偏头痛。次要目的是比较在最大运动试验后出现偏头痛发作的参与者与未出现偏头痛发作的参与者。
共有19名报告运动是其偏头痛潜在诱发因素的患者纳入本研究。在为期1个月的基线期测量偏头痛发作频率后，对每位患者进行两次直至力竭的蹬车测力计测试。
共有14名患者接受了重测，其中3名在两次测试后均报告出现偏头痛，5名在其中一次测试后出现偏头痛，6名在两次测试后均未报告出现偏头痛。我们观察到基线偏头痛发作频率较高的患者在进行1次或2次测试后出现偏头痛的风险更高（p = 0.036）。
总之，该研究表明，尽管最大有氧运动可诱发偏头痛发作，但即使在那些报告运动是偏头痛诱发因素的人群中，也并非总能引发发作。
