Article Synopsis
- - The study investigates the relative age effect (RAE) in Norwegian track and field athletes, focusing on how being born early in the year can influence performance in sports, specifically sprinting versus middle-distance running.
- - Analysis of data from nearly 29,000 athletes revealed that older competitors within the same age group tend to perform better, with a notably higher advantage observed in males for 60m sprints compared to middle-distance events.
- - The findings suggest that athletes born in the first quarter of the year have significantly better odds of ranking in the top-100, with males showing a stronger advantage that appears to diminish with increasing age, especially in middle-distance running.
Introduction: Sex-specific differences that arise during puberty have a pronounced effect on the training process. However, the consequences this should have for goal-setting, planning and implementation of training for boys and girls of different ages remains poorly understood. The aim of this study was to quantify performance developments in athletic running and jumping disciplines in the age range 11-18 and identify progression differences as a function of age, discipline and sex.

We introduce the Fishery Performance Indicators (FPIs), a broadly applicable and flexible tool for assessing performance in individual fisheries, and for establishing cross-sectional links between enabling conditions, management strategies and triple bottom line outcomes. Conceptually separating measures of performance, the FPIs use 68 individual outcome metrics--coded on a 1 to 5 scale based on expert assessment to facilitate application to data poor fisheries and sectors--that can be partitioned into sector-based or triple-bottom-line sustainability-based interpretative indicators.

Although three billion people worldwide use seafood as a key source of animal protein, the Food and Agriculture Organization (FAO) of the United Nations-which compiles prices for other major food categories-has not tracked seafood prices. We fill this gap by developing an index of global seafood prices that can help to understand food crises and may assist in averting them.
