David Vs. Goliath: Playing Against Maturity Matched or Un-Matched Opposition Results in Distinct Physical Performance and Spatial Exploration Behavior for Pre-Peak Height Velocity Basketball Athletes
Abstrct
This paper seeks to examine the impact of maturity matching upon physical performance and spatial exploration behaviour for pre-PHV basketball players. For this purpose, thirty-two under-14 to 16 basketball players are assigned to different teams according to maturity status (Pre-, Mid-, and Post-Peak Height Velocity [PHV]), and instructed to participate in basketball matches against matched (same maturity status), and un-matched (different maturity status) opposition. Maturity status is estimated considering the percentage of predicted adult height. Workload data has been collected via WIMU PRO Local Positioning System. Heart rate is recorded with individual HR monitors. Only data from pre-PHV players has been considered for further analysis. The Pre-PHV players cover greater distances when competing against post-PHV players than against matched opposition (p < 0.05, large) and Mid-PHV (p < 0.01, very large) teams. It bears to note that they perform more accelerations (p < 0.05, large) and decelerations (p < 0.05, very large) when competing against matched opposition than against the Mid-PHV teams. Furthermore, the Pre-PHV players present higher mean values for high-intensity accelerations (> 2 m∙s-2; p < 0.01, very large), average speed (p < 0.05, very large), body impacts (> 5g; p < 0.05, large), and Player Load (p < 0.01, very large) when competing against post-PHV than against Mid-PHV players. It is also found that the pre-PHV explore more space (large effect) when competing in maturity matched games than when competing against un-matched opposition teams. Pre-PHV athletes seem to benefit from playing in maturity-matched situations, to reduce the physicality of the game and to have an optimized perception of spatial-temporal information.

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.
