Bike-riding boosts PSA levels

Melbourne researchers found that total PSA (tPSA) levels increased by 9.5% on average, corresponding to a 0.23ng/ml increase, in 129 men when measured within five minutes of them finishing recreational one-day cycling events of between 55km and 160km.

All of the participants were aged over 50, with an average age of 55, and using age-based normal PSA ranges, eight participants had an elevated tPSA after their ride, compared with five before their ride.
