Syncope after exercise is often neurally mediated, i.e. post-exercise vasovagal syncope. This condition is typically diagnosed in '''young fit, furthermore healthy young patients.'''

Foremost, the diagnostic workup of all patients presenting with exercise-related syncope is aimed at '''excluding dangerous [[Cardiac syncope|cardiac conditions]]''' and includes echocardiography and exercise testing <cite>Krediet04b</cite>.  
Foremost, the diagnostic workup of all patients presenting with exercise-related syncope is aimed at '''excluding dangerous [[Cardiac syncope|cardiac conditions]]''' and includes echocardiography and exercise testing <cite>Krediet04b</cite>. Risk factors for a cardial problem are fainting while sitting or supine and suddenly fainting ''during'' exercise without presyncope.

Characteristically, syncope may occur while the individual is '''standing motionless''' during the first five to ten minutes after exercise <cite>Bjurstedt</cite>. Especially athletes in the (ultra) endurance sports are at risk for post exercise vasovagal syncope e.g. after marathon swimming (Finlay et al., 1995) or marathon running (Tsutsumi & Hara, 1979;Holtzhausen & Noakes, 1995;Holtzhausen & Noakes, 1997).

Vasovagal syncope after routine treadmill testing is rare (estimated 0,2% (Schlesinger, 1973)). However, when treadmill testing is immediately followed by passive head-up tilt testing, this percentage can increase up to 50-70% (Bjurstedt et al., 1983).
