Calcium Isotopes in Human Urine as a Diagnostic Tool for Bone Loss: Additional Evidence for Time Delays in Bone Response to Experimental Bed Rest.

Frontiers in physiology

Heuser A, Frings-Meuthen P, Rittweger J, Galer SJG.

Front Physiol. 2019 Jan 25;10:12. doi: 10.3389/fphys.2019.00012. eCollection 2019.

The calcium (Ca) isotopic composition in urine during bed rest has been demonstrated to be systematically light, indicating a negative bone mineral balance (i.e., bone loss). Here we present new Ca isotope data on urine during the "nutritional countermeasures"...

Resting Energy Expenditure of Master Athletes: Accuracy of Predictive Equations and Primary Determinants.

Frontiers in physiology

Frings-Meuthen P, Henkel S, Boschmann M, Chilibeck PD, Alvero Cruz JR, Hoffmann F, Möstl S, Mittag U, Mulder E, Rittweger N, Sies W, Tanaka H, Rittweger J.

Resting energy expenditure (REE) is determined mainly by fat-free mass (FFM). FFM depends also on daily physical activity. REE normally decreases with increased age due to decreases in FFM and physical activity. Measuring REE is essential for estimating total...

Age-Related Decline in Vertical Jumping Performance in Masters Track and Field Athletes: Concomitant Influence of Body Composition.

Frontiers in physiology

Alvero-Cruz JR, Brikis M, Chilibeck P, Frings-Meuthen P, Vico Guzmán JF, Mittag U, Michely S, Mulder E, Tanaka H, Tank J, Rittweger J.
PMID: 33868010
Front Physiol. 2021 Apr 01;12:643649. doi: 10.3389/fphys.2021.643649. eCollection 2021.

Vertical jumping power declines with advancing age, which is theoretically explicable by loss of muscle mass and increases in body fat. However, the results of previous cross-sectional studies remain inconsistent on these relationships. The present study included 256 masters...
