Summary: The study found that relative lower extremity lengths increase with age in children, while relative subcutaneous adipose tissue thickness decreases. Muscle size increases with age in proportion to limb length. Torque-producing capacity is highly variable in children and rapidly develops towards adulthood.

Summary: This study found that EE2 and G1 have negative effects on the growth, muscle parameters, and expression of growth-related genes in seabreams, resulting in hypertrophy of white fibers and abnormal expression of key genes.

Summary: Previous belief of indeterminate growth in lizards has been challenged by recent studies showing bone growth plate closure as a stoppage of bone prolongation. This has significant consequences for understanding the causes of sexual size dimorphism in squamate reptiles.

Summary: The study found that the heart of Drosophila scales precisely with embryo length, while the hindgut shows scaling with embryo size under large-scale changes in artificially smaller embryos, but not within wild-type size variation. The VNC displays weak scaling behavior, suggesting it may have an intrinsic minimal length largely independent of embryo length.

Summary: This cross-sectional study found that greater peak torque and higher myotendinous density at the ankle are associated with a more plate-like architecture at the distal tibia. Additionally, the strength of muscles around the ankle is correlated with plate-like trabeculae at the distal tibia.

Summary: Ectotherms are predicted to shrink with global warming, but faster juvenile growth rates may lead to larger size-at-age of young organisms. This study used a two-decade long time series to examine the effects of warming on body growth, size-at-age, and mortality rates of Eurasian perch. The results show that, despite higher mortality rates, the faster growth rates resulted in a larger mean size in the heated area.

Summary: The study aimed to develop a screening questionnaire to detect sarcopenic obesity in young and middle-aged female adults. Findings indicated that individuals who frequently dieted had lower levels of FFM and BMR.

Summary: The study demonstrated that dietary methionine could enhance the growth performance of Monopterus albus, especially for muscle growth and development, improving muscle texture and main nutritional factors (amino acids, glycogen), and reducing the content of lactic acid in muscle.

Summary: Size-based dominance hierarchies are influenced by dominance status and social status, with size differences often emerging in competition and growth suppression. Investment in growth suppression is favored when dominants and subordinates are similar in size, leading to unexpected size ratios within dominance hierarchies. Variation in feedback mechanisms among growth, size, and status can explain emergent size structures and conflicts within groups.

Summary: The study found that prolonged resistance exercise training in older adults leads to a decrease in the percentage of small muscle fibers and an increase in the percentage of the largest muscle fibers. The change in the percentage of small fibers is associated with an increase in overall myonuclear domain size, while the change in the percentage of the largest fibers is linked to an overall increase in myonuclear content.

Summary: Estimating population variables and preservation rates of postjuvenile T. rex involves using data from living species and the relationship between population density and body mass. The uncertainties in these estimations primarily stem from the variance in the density-body mass relationship, resulting in a wide range spanning two orders of magnitude.

Summary: The early and late phases of force development during muscle contraction are associated with intrinsic contractile properties and maximal force, respectively. There are differences in rate of force development and muscle fiber function between young and old individuals. Electrically evoked twitches can serve as a predictor of early rate of force development in young individuals, but not in older ones.

Summary: The study provides a comprehensive resource of protein turnover in mouse tissues and develops a visualization platform for data analysis. Understanding protein turnover is critical for cellular physiology, tissue maintenance, and drug development. The dataset and visualization software will guide future studies on mammalian protein turnover in different physiological and pathological conditions.

Summary: This study confirmed the effects of body size and game position on the interactions of young soccer players in small-sided games. The findings showed that midfielders have higher network prominence values in offensive plays, which is independent of their body size.
