Figure 4. Maximal post-ischaemic vasodilatation in the dominant and non-dominant arms of tennis players and control subjects with similar , measured with plethysmography after 5 min of arterial occlusion coupled with 1 min of exercise.

In the tennis players maximal forearm hyperaemia was 42% higher in the dominant than in the non-dominant forearm (Sinoway et al. 1986).
