- Abstract:
- Sports and in particular cycling are assumed to influence PSA in serum. Controversial scientific results were the motivation to examine the influence of a standardized test on a cycling ergometer and a treadmill on PSA concentrations in elderly men with elevated PSA levels and a benign prostate hyperplasia. A total of 21 male volunteers (aged 61 ± 5 years, tPSA 7.7 ± 3.0 ng/ml and benign prostate hyperplasia with a prostate volume of 54 ± 18 ml) performed a 1 h cycling test on a cycling ergometer. A subgroup of 15 volunteers also performed a 1 h test on a treadmill. Blood samples were drawn before and several times after the cycling stress test up to 7 days afterwards (up to 120 min after the test on the treadmill) to determine total PSA (tPSA), complexed PSA (cPSA) and free PSA (fPSA). The average increase in tPSA of 1.9 ± 1.7 ng/ml (25%) after the cycling exercise test was significant. After the treadmill exercise the PSA increase was not as high, but with 1.0 ± 1.0 ng/ml (12%) was also significant. On average the levels of PSA returned to the basic level 48 h after the cycling test, but in individual cases it took longer. fPSA showed the most noticeable increase after cycling with 92% on average. There was no correlation between increase in PSA and prostate volume. Men should abstain from physical exercise, especially from cycling for several days and at least for 24 h before PSA measurements are carried out. This applies to patients with elevated PSA levels (>4 ng/ml) when a PSA follow-up is being carried out.
