Bone mineral density in elite adolescent female figure skaters.

Journal of the International Society of Sports Nutrition

Prelack K, Dwyer J, Ziegler P, Kehayias JJ.
PMID: 23270306
J Int Soc Sports Nutr. 2012 Dec 27;9(1):57. doi: 10.1186/1550-2783-9-57.

UNLABELLED: Elite adolescent figure skaters must accommodate both the physical demands of competitive training and the accelerated rate of bone growth that is associated with adolescence, in this sport that emphasizes leanness. Although, these athletes apparently have sufficient osteogenic...

Quantum sensors based on nitrogen-vacancy centers in diamond have emerged as a promising detection modality for nuclear magnetic resonance (NMR) spectroscopy owing to their micrometer-scale detection volume and noninductive-based detection. A remaining challenge is to realize sufficiently high spectral...

Nonanomalous discrete R symmetry decrees three generations.
