Relative Age Effect and Biological Maturation on Inhibitory Control of Motor Response in Basketball
Abstrct
In the context of sports, relative age effect (RAE) generates transitional differences on maturational development non-linear at chronological age. This leads to a lack of selection opportunities in sport teams during pubertal stage. Biological maturation (BM) is the main modulator of these drastic changes in maturation, which affect sport performance. 34 young male basketball players [Mage= 10,94 (±1,51) years] are evaluated on inhibitory control of motor response through the computerized Go/no-go task. The study uses two BM indices: “maturity offset” and “percentage of adult height”. Results found significant differences on cognitive performance between two different chronological age groups (under10 / top10 years old.). Top10 players show a lower response time (RT) and accuracy adjusted response time than under10. However, the study does not find RAE (birth semester) on cognition. Percentage of adult height predicts both RT and accuracy adjusted RT performance in the entire sample, while maturity offset also did it, but only in the greater chronological age group (top10). Sports field research should consider BM control to explain RAE, and the influence on executive functions, that are crucial for interactive sport performance.

The advent of cinema brought with it its use as a propaganda device with which to transmit ideals and doctrines. As a result, newsreels and cinema documentaries were born with the aim of showing the «most relevant» news of the country and abroad, the former with a shorter duration. In this study, the Spanish NO-DO and «Sucesos Argentinos» are used as primary sources to interpret the images and imaginaries that were projected between 1943 and 1955 on female physical culture. The intention is to understand the official discourse of both political regimes on what Argentinean and Spanish society should be like, especially by questioning those meanings about women. In total, 69 issues of NO-DO and 14 editions of «Sucesos Argentinos» have been found which aim to show female physical culture in this period. The female physical culture shown in both newsreels was aimed at strengthening women’s bodies so that they could carry out their «natural functions» (mother, wife, housewife), as well as highlighting their «inferiority» in relation to men through lower impact activities and the homogenization of bodies through clothing, and the performance of the same exercises in synchrony. And all this in countries with different regimes, but which, in the end, coincided.
