ABSTRACT

RESUMEN: El Código de Puntuación de la Federación Internacional de Gimnasia en las distintas disciplinas de la Gimnasia, sufre modificaciones y se actualiza después de cada Juego Olímpico; obligando a una constante actualización de los jueces y entrenadores. Estos cambios rigen para los 4 años que dura el ciclo olímpico, y se dan a conocer en los Cursos Internacionales de Jueces que imparte la Federación Internacional de Gimnasia para cada disciplina deportiva. Por la pandemia que ha afectado al mundo, y por consecuencia al deporte, los Juegos Olímpicos de Tokio 2020 fueron pospuestos para el año 2021; y con esto, se ha postergado en un año la entrada en vigencia de los reglamentos de la Gimnasia del próximo ciclo olímpico, periodo que se extenderá extraordinariamente desde el año 2022 al 2024.El presente trabajo tiene como objetivo, dar a conocer los principales cambios que está proponiendo el Comité Técnico Femenino de la Federación Internacional de Gimnasia, en la primera edición del nuevo Código de Puntuación de la Gimnasia Artística Femenina para el ciclo olímpico 2022-2024.Palabras clave: Gimnasia, gimnasia artística, gimnasia artística femenina, código de puntuación, Federación Internacional de Gimnasia


ABSTRACT: The International Gymnastics Federation's Code of Points, for different disciplines in Gymnastics, undergoes modifications and is updated after each Olympic Game, forcing a constant update of the judges and coaches. These changes apply for the 4 years of the Olympic cycle and are announced in the International Judges Courses, imparted by the International Gymnastics Federation for each sport discipline after the Olympics.Because of how the pandemic has affected the world, and consequently sports, the Olympic Games of Tokyo 2020 were postponed to the year 2021. With this, the validity of Gymnastic regulations for the next Olympic cycle has been postponed by one year, so the cycle will extraordinarily extend from 2022 to 2024.The objective of this article is to announce the main changes that the International Gymnastics Federation's Women's Technical Committee is proposing, in the first edition of the new Code of Points for the Women's Artistic Gymnastics cycle of 2022-2024.

ABSTRACT

Since its discovery, myostatin (MSTN) has been at the forefront of muscle therapy research because intrinsic mutations or inhibition of this protein, by either pharmacological or genetic means, result in muscle hypertrophy and hyperplasia. In addition to muscle growth, MSTN inhibition potentially disturbs connective tissue, leads to strength modulation, facilitates myoblast transplantation, promotes tissue regeneration, induces adipose tissue thermogenesis and increases muscle oxidative phenotype. It is also known that current advances in gene therapy have an impact on sports because of the illicit use of such methods. However, the adverse effects of these methods, their impact on athletic performance in humans and the means of detecting gene doping are as yet unknown. The aim of the present review is to discuss biosynthesis, genetic variants, pharmacological/genetic manipulation, doping and athletic performance in relation to the MSTN pathway. As will be concluded from the manuscript, MSTN emerges as a promising molecule for combating muscle wasting diseases and for triggering wide-ranging discussion in view of its possible use in gene doping.


Desde sua descoberta, a miostatina (MSTN) entrou na linha de frente em pesquisas relacionadas às terapias musculares porque mutações intrínsecas ou inibição desta proteína tanto por abordagens farmacológicas como genéticas resultam em hipertrofia muscular e hiperplasia. Além do aumento da massa muscular, a inibição de MSTN potencialmente prejudica o tecido conectivo, modula a força muscular, facilita o transplante de mioblastos, promove regeneração tecidual, induz termogênese no tecido adiposo e aumenta a oxidação na musculatura esquelética. É também sabido que os atuais avanços em terapia gênica têm uma relação com o esporte devido ao uso ilícito de tal método. Os efeitos adversos de tal abordagem, seus efeitos no desempenho de atletas e métodos para detectar doping genético são, contudo, desconhecidos. O objetivo da presente revisão de literatura foi discutir biossíntese, variantes genéticas, manipulação genética e farmacológica, e doping relacionado à via da MSTN. Como será concluído do manuscrito, a MSTN emerge como uma molécula promissora para combater doenças atróficas musculares e para gerar muitas discussões devido à sua possível utilização em doping genético.
