Differences in Anthropometric Parameters, Physical Fitness, and Kicking Speed in Young Football Players According to Performance Level, Playing Position, and Relative Age Effect: A Population-Based Study.

Oddsson, HR, Friðgeirsdóttir, KÝ, Hafliðadóttir, L, Einarsson, IÞ, Kristjánsdóttir, H, and Saavedra, JM. Differences in anthropometric parameters, physical fitness, and kicking speed in young football players according to performance level, playing position, and relative age effect: a population-based study. J Strength Cond Res XX(X): 000-000, 2024-The objectives of this study were to determine (a) the differences, both in male and female players, in anthropometric parameters, physical fitness, and kicking speed based on the players' level and position on the field; (b) whether there is a relative age effect based on the players' level, and (c) whether there is a relationship between the relative age effect and the anthropometric parameters, physical fitness, and kicking speed parameters.

The Role of the GH/IGF Axis in Statural Growth and Harmonious Body Proportionality: In Search of Vitruvian Man.

Unlabelled: Body proportions are the objective parameters of harmonious growth and reflect the interplay of genetic, environmental, metabolic, and hormonal actions. Mutations in the growth hormone receptor gene (GHR) result in severe growth failure. The study of individuals affected with these mutations can inform us about the role of growth peptides in harmonious, proportional growth.

Healthy Diets at the Intersection of Human and Planetary Health.

Our diets are the greatest determinant of health, and what we eat is sustained and shaped by the food we produce. Food systems have increased production to feed the growing world population, which has also led to a dietary transition, with increases in energy and protein intakes, and only modest improvements in micronutrient density. Thus, undernutrition has decreased globally, while non-communicable diseases are dramatically increasing.
