Abstract

We investigated the short-term (1 hour-3 days) effects of a 45 minute run on calcium, parathyroid hormone, the carboxyterminal propeptide of type I procollagen (PICP), and the immunoactive carboxyterminal telopeptide of type I collagen in serum (ICTP) in young females. Fourteen healthy young women, aged 25.2 +/- 0.6 years (mean +/- SEM) with regular menstruations, participated. The test was outdoor jogging for 45 minutes at an intensity of 50% of VO2 max. Blood samples were collected 15 minutes before the test and 1, 24, and 72 hours after the test. The measured values were adjusted for changes in plasma volume. A significant decrease of ionized calcium was observed at 1 hour (P < 0.001) and 72 hours (P < 0.05) and a significant increase of parathyroid hormone (PTH) was noted 24 (P < 0.01) and 72 hours (P < 0.05) after the test. A significant decrease of PICP at 1 hour (P < 0.05) was followed by an increase after 24 (P < 0.01) and 72 hours (P < 0.001) and a significant increase in ICTP was noted at 24 and 72 hours (P < 0.05). A strong positive correlation was found between serum levels of PICP and ICTP (r = 0. 55-0.84; P < 0.05) throughout the experiment. In conclusion, young females showed biochemical signs of increased bone collagen turnover and altered homeostasis of calcium and PTH after a single bout of moderate endurance exercise.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
