Plasma renin activity during and after dynamic and static exercise.

The effect of dynamic and static exercise on plasma renin activity was investigated in three normal males. Near maximal supine exercise for 10 min on a bicycle ergometer caused a small increase in plasma renin activity during exertion with a much larger increase during recovery which reached a peak between 10-20 min. Supine exercise at half this level and static exercise (hand-grip) had no detectable effect on plasma renin activity.
