Effect of Instability Resistance Training on Sports Performance Among Athletes: A Systematic Review
Abstrct
The aim of this investigation is to systematically review the impact of instability resistance training (IRT) on sports performance, providing both theoretical and practical insights for athletes in routine training. Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, databases such as Web of Science, EBSCOhost (SPORTDiscus), PubMed, and Scopus were employed for the comprehensive collection of original references. A total of 402 articles were gathered, with only 17 meeting the specified analytical criteria. The quality of each article was assessed using the PEDro scale, resulting in scores ranging from 2 to 6 across the 17 articles. IRT exhibited significant efficacy in enhancing sports and athletic performance across disciplines such as Judo, cricket, weightlifting, rifle shooting, sprinting, handball, soccer, and basketball, with the exception of 25 male elite golf players. Theoretically, this study posits that IRT, rooted in functional training, represents an advancement in activating core muscles, fostering coordination between agonistic and antagonistic muscles, and enhancing muscle proprioception – pivotal physiological foundations for augmenting exercise performance. Moreover, by emphasizing the integration of training actions and the role of the "power chain," IRT, adopting an unstable format akin to specialized exercises or increasing difficulty, aims to enhance training efficiency. Empirical evidence demonstrates that continuous IRT positively influences sports performance, with moderate IRT identified as a secure and effective stimulation method. Consequently, this review advocates for the incorporation of IRT into athletes' daily training routines to optimize sports 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.
