Key result
Prolonged cycling exercise increased plasma ANP concentration from 22 pg/ml at rest to 59.4 pg/ml at 30 minutes, with a leveling-off thereafter.

Transient ANP plateau during prolonged exercise contrasts ongoing renin-aldosterone rise; hypothesis-generating for differential regulation in healthy adults.
Does prolonged cycling exercise increase plasma atriopeptin concentration in healthy young adults?
Absolute Event Rate: 59.4% vs 22%
Prolonged cycling exercise induces an early increase in plasma atriopeptin that levels off after 30 minutes, alongside continuous increases in aldosterone and plasma renin activity.
Perrault et al. (1991) studied Healthy (n=11). Prolonged cycling exercise vs. Rest was evaluated on Plasma ANP concentration at 30 minutes (pg/ml). Prolonged cycling exercise increased plasma ANP concentration from 22 pg/ml at rest to 59.4 pg/ml at 30 minutes, with a leveling-off thereafter.
