ABSTRACT
Introducción: Investigaciones han determinado que la implementación de programas de actividad física mejora la salud mental. Sin embargo, aún existen dudas sobre la relación entre fuerza muscular y la presencia de trastornos psicosociales como ansiedad y estrés en la población universitaria. Objetivo: Relacionar la condición física, específicamente la fuerza prensil, con la presencia de Ansiedad-Rasgo en estudiantes mujeres. Materiales y métodos: Investigación empírica con estrategia asociativa predictiva, con un diseño predictivo transversal. La muestra fue de 30 estudiantes mujeres de pregrado. Las variables físicas predictoras evaluadas fueron antropometría, fuerza prensil y consumo máximo de oxígeno, mientras que la Ansiedad-Rasgo se midió por medio del Cuestionario de Ansiedad Estado Rasgo (STAI). Se realizó análisis estadístico con una regresión logística ordinal entre las variables físicas predictoras y nivel de Ansiedad-Rasgo. Resultados: Se evidenció que sólo la fuerza prensil fue estadísticamente significativa (p=0,033). Este análisis expresado en Odds Ratio, asume un 74,36% de probabilidad que a un menor nivel de fuerza prensil, mayor presencia de Ansiedad-Rasgo. Conclusiones: La fuerza prensil, además de ser un parámetro físico que permite detectar riesgo cardiovascular y patologías asociadas, también debería ser considerada en la determinación de alteraciones en salud mental.
Introduction: Research has revealed that the implementation of physical activity programs improves mental health. However, there are still doubts about the relationship between muscle strength and the presence of psychosocial disorders such as anxiety and stress in the university student population. Objective: To study the association of a physical condition (grip strength) and the presence of Trait-Anxiety in female students. Materials and methods: An empirical research with a predictive associative strategy was conducted on a sample of 30 female undergraduate students. The predictor physical variables assessed were anthropometry, grip strength, and maximum oxygen consumption. Trait-Anxiety was evaluated using the State-Trait Anxiety Inventory (STAI). Statistical analysis was performed through ordinal logistic regression between predictor physical variables and level of Trait-Anxiety. Results: Only grip strength was statistically significant (p=0.033). This analysis, expressed as Odds Ratio, assumes a 74.36% probability that the lower level of grip strength, the greater chances of having Trait-Anxiety. Conclusions: Grip strength is not only a physical parameter to detect cardiovascular risks and associated pathologies, but also it should be used to identify mental health disorders.

Abstract Introduction: The development of strength has shown to be beneficial to sports performance and health. However, during strength training, they also produce alterations in muscle fatigue indicators, leading to a decrease in the ability to generate strength. Despite this, there is still not enough knowledge about the levels of muscle fatigue generated by different methods of strength training and how this information can be integrated into sports planning. Review and analyze the studies existing between January 2009 and January 2019 that have used indicators of muscle fatigue established in the search terms during and after strength training as measurement variables. Evidence acquisition: The study corresponds to a systematic review of previously published studies, following the PRISMA model. Articles published between 2009 and 2019 that measured muscle fatigue indicators during and after strength training were evaluated. The electronic search was conducted through Web of Science, Scopus, Sport Discus, PubMed, and Medline. We included all articles that used a strength protocol and also measured indicators of muscle fatigue and its possible effect on physical performance. Evidence synthesis: A total of 39 articles were found, which were stratified according to the protocol used: (i) plyometric training, (ii) Bodypump® training, (iii) occlusion training, (iv) variable resistance training, (v) conventional strength training, (vi) eccentric strength training, (vii) rest times in strength training and (viii) concurrent training. Conclusion: At the end of the systematic review, it was shown that the different training methodologies for strength development generate increases in muscle fatigue indicators, and the increase generated in the different muscle fatigue indicators depends both on the methodology used and on the type of population, sex, level of training and type of sport. The most-reported indicators are [La], HR and RPE, DOM, MR variation, and ammonium.

Resumen El incremento en los niveles de ansiedad y estrés se han relacionado la mayoría de las veces con efectos negativos para el desempeño de atletas, por lo que la utilización de habilidades psicológicas como el autodiálogo se han usado para manejar la ansiedad y el estrés para obtener un mejor rendimiento deportivo. Este artículo presenta una revisión sistemática centrada en intervenciones que utilizaron el autodiálogo como método de entrenamiento mental para controlar niveles de ansiedad y estrés en jugadores de tenis. Se encontraron solamente 3 estudios que investigaron el método de autodiálogo en variables psicológicas y apenas un estudio que evaluó el efecto sobre la ansiedad. Por esta razón, se sugieren más investigaciones que aborden las variables mencionadas.
Abstract The increase in levels of anxiety and stress have been related most of the time to negative effects on the performance of athletes, so the use of psychological skills such as self-talk has been used to manage anxiety and stress to obtain better sports performance. This article presents a systematic review focused on interventions that used self-talk as a method of mental training to control levels of anxiety and stress in tennis players. We found only 3 studies that investigated the method of self-talk in psychological variables and only one study that evaluate the effect on anxiety. For that reason, more research is suggested to addresses these variables.

ABSTRACT
Background: If aerobic capacity is stimulated early in life, maximal oxygen consumption during adulthood is assured. Aim: To analyze the effects of a high intensity interval training (HIIT) in adolescents on the maximal oxygen consumption (VO2max) measured using the 20-m shuttle run test (20mSRT). Material and Methods: Twenty eight teenagers aged 13 ± 0.6 years were divided in two groups of 14 subjects each. One group was to a 16 sessions of HIIT interval training based on their individual maximal aerobic speed and the other continued with their usual exercise done at school. At baseline and the end of the intervention VO2max was measured using the 20mSTR. Results: At the end of the intervention, the trained teenagers significantly improved their VO2max and the time spent in the 20mSTR. Conclusions: A HIIT program based on the individual maximal aerobic speed improves VO2max in adolescents.
