Probably the wrong area for this thread, but following my first attempt at tabata, I suffered a mong of a headache(which I still have the remnants of) :021: , this is why. Very interseting article.
Clinical manifestation
An activity-related headache is one that occurs during or shortly after physical activity. The benign varieties (ie, those unassociated with cranial or intracranial pathology) may be classified into several different categories (Dimeff 1992).
Activity-related headaches that appear to be caused by increased venous pressure (cough headache): These headaches typically follow or accompany activities—coughing, sneezing, bending over, laughing, crying, heavy lifting, straining at stool—that incorporate the Valsalva maneuver (Symonds 1956; Rooke 1968; Ekbom 1986). Benign cough headaches (ie, those unassociated with any intracranial pathology) are sudden in onset, reach a peak intensity rapidly, and then either disappear or fade to a dull ache that may remain for several hours. The pain is moderate to severe in intensity, with a sharp or stabbing quality (Pascual et al 1996). It is bilateral in most patients. The major locus of pain can be in the occipital, frontal, or temporal regions or at vertex with radiation to the frontal regions bilaterally. It is usually not associated with nausea or vomiting. Patients are usually pain-free between attacks. Cough headache is provoked specifically by coughing, sneezing, or other such maneuvers, whereas other headache types (eg, migraine, post-lumbar puncture headache) are often augmented by cough.
Exertion-produced vascular headaches: When seen in patients without any cranial or intracranial pathology, this type of headache is usually referred to as "benign exertional headache" (Table 1). Headache during or following exertion implies that adequate physical activity has produced the requisite cephalgia. Mental effort, no matter how onerous, is not included here. How much effort, then, causes headache? Arbitrarily, enough to double the resting pulse for at least 10 seconds, but ordinarily for minutes or hours. Running, rowing, and tennis are reported causes. Several recent papers from Japan have emphasized exertional headache evoked by swimming (Indo and Takahashi 1990; Mizoguchi et al 1990).
Usually the headache is described as aching, pounding, or throbbing, and has many characteristics of migraine, with associated nausea, vomiting, and photophobia. It may be bilateral or unilateral (Pascual et al 1996). Generally the headache occurs at the peak of exercise and subsides as activity ceases. A more prolonged form of exertional headache has been reported by Diamond (Diamond 1982b).
Heat, high humidity, conditions of changing barometric pressure, exercise at high altitudes, caffeine, poor nutrition, hypoglycemia, and alcohol usage are believed to be contributing factors (Dalessio 1974). Exertional headache occurs both in poorly conditioned persons who exercise infrequently and in trained athletes.
The majority of cases occur in patients who have migraine or who have a family history of migraine.
Diagnostic Criteria for Benign Exertional Headache
• Is specifically brought on by physical exercise
• Is bilateral, throbbing in nature at onset and may develop migrainous features in those
patients susceptible to migraine
• Lasts from 5 minutes to 24 hours
• Is prevented by avoiding excessive exertion, particularly in hot weather or at high altitude
• Is not associated with any systemic or intracranial disorder
(Headache Classification Committee of the International Headache Society 1988)
Weight lifter's headache: Intense pain that originates in the occipital/nuchal region and radiates into the parietal area can occur as a result of the maximal exertion during weight lifting (Powell 1982). The pain is steady and described as boring. It gradually declines, leaving a residual ache that may lasts days or weeks. This headache may be caused by stretching of the cervical ligaments and tendons with development of excessive muscle contraction.
Headaches associated with sexual activity: Headaches may occur during sexual activities associated with intercourse or independent of intercourse (eg, masturbation) or orgasm.
Cardiac cephalgia: Rare patients with arteriosclerotic coronary artery disease may have exertional headaches beginning with vigorous exercise and relieved by rest (Lipton et al 1997; Lance and Lambros 1998). Treadmill testing can reveal electrocardiographic changes appearing with the headache.
