Bacciotti, Sarita; Baxter-Jones, Adam; Gaya, Adroaldo; Maia, José This study aimed to identify physique characteristics anthropometry, somatotype, body proportionality of Brazilian female artistic gymnasts, and to compare them across competitive levels sub-elite versus non-elite within competitive age-categories.
Gymnasts were assessed for 16 anthropometric traits height, weight, lengths, widths, girths, and skinfolds ; somatotype was determined according to Heath-Carter method, body fat was estimated by bioimpedance, and proportionality was computed based on the z-phantom strategy.
In general, mesomorphy was the salient somatotype component in all rhonda forlaw perte de poids, and an increase in endomorphy, followed by a decrease in ectomorphy across age was observed. Regarding proportionality, profile similarity was found between sub-elite and non-elite within age-categories.
The aim of the following review is to present the most important studies concerning the physical properties of water-solutes mixtures used in cryobiology. Cryobiology is a branch of biology which deals with the very low temperature behaviour of cells.
This technique is developed today in several directions. The creation of banks of cells and perhaps in a short time of small organs, is the purpose of much research in this domain.
Before freezing, living cells are generally put in a solution containing one or more solutes. The role of these solutes is to protect the cells against damage due to crystallization of water cryoprotectors. The mechanisms of cryoprotection are not well known ; nevertheless the vitreous state formation during cooling is often invoked.
The conditions in which the vitreous state is obtained, maintained during cooling, storage at low temperature and rewarming can be defined by physical studies presented in the following review. Le présent travail est essentiellement une revue bibliographique des principales études physiques qui ont été réalisées avec des solutions de composés habituellement employés en cryobiologie. La cryobiologie est une branche de la biologie qui s'intéresse au comportement des cellules à basse température.
Cette discipline est actuellement en plein développement dans des domaines très divers. Son principal but est la création de banques de cellules de plus en plus complexes avec comme perspective la conservation des organes.
Les cellules vivantes sont généralement placées avant congélation dans une solution rhonda forlaw perte de poids divers composés dont le rôle est de protéger les cellules contre les effets de la cristallisation de l'eau.
