Vertical Jumps

El voleibol femenino se práctica en todo el mundo a nivel profesional y amateur. Los saltos verticales son una parte fundamental para el desarrollo de este deporte, por lo que el entrenamiento pliométrico puede ser eficaz para un aumento del rendimiento. El propósito de estudio fue describir cuáles han sido los métodos y programas de entrenamiento pliométrico en mujeres que practican voleibol, así como el resultado obtenido en función de estos. El proceso de búsqueda en las bases de datos se llevó a cabo desde Marzo hasta Junio de 2016. Las bases de datos consultadas fueron Pubmed, Web of Science, Cochrane y SPORTDiscus. La revisión sistemática fue realizada bajo las recomendaciones de la declaración PRISMA. La calidad metodológica de los estudios fue evaluada mediante la Escala PEDro. Como resultado, se obtuvieron un total de 205 artículos tras eliminar aquellos que estaban por duplicado. Finalmente 7 artículos fueron seleccionados. Los resultados principales fueron que aquellos estudios que utilizan deportistas amateurs obtienen mejores resultados que los realizados con deportistas profesionales cuando se realizan programas de entrenamiento pliométrico. También se indica que un período de entrenamiento pliométrico de baja intensidad puede prevenir una disminución en la altura del salto vertical; así como es necesario programar la pretemporada para evitar pérdida en la capacidad de salto. Todo ello parece indicar, como conclusión, que es necesario una disminución del volumen y un aumento de la intensidad en el entrenamiento pliométrico.Abstract. Female volleyball is practiced all over the world at a professional and amateur level. Vertical jumps are a fundamental part of the development of this sport. In this sense, plyometric training can be effective for increased performance. The purpose of the study was to describe the methods and programs of plyometric training in women volleyball players, as well as the results obtained from them. The following electronic databases were searched March to June 2016. Electronic databases consulted were Pubmed, Web of Science, Cochrane and SPORTDiscus. This systematic review was performed following PRISMA statement. PEDro scale was used to evaluated the methodological quality of the included studies. As total of 205 articles were obtained after remove duplicates. Finally 7 articles were selected. The main results were that those studies using amateur athletes obtain better results than those performed with professional athletes when performing plyometric training programs. It is also indicated that a period of low intensity plyometric training could prevent a decrease in vertical jump height; As well as it is necessary to schedule the preseason to avoid loss in the ability to jump. All this seems to indicate, in conclusion, that a decrease in volume and an increase in intensity in the training of plyometric training is necessary.

El objetivo del estudio fue investigar los efectos de un entrenamiento de fuerza más una suplementación adicional sobre deportistas adultos no profesionales y vegetarianos. Una revisión sistemática de las bases de datos MEDLINE (PubMed), Scopus, SportDiscus y WOS (Web of Science) fue realizada siguiendo el modelo PICO, utilizando términos que representasen a personas vegetarianas de entre 18 y 64 años que hubiesen realizado una intervención basada en un entrenamiento de fuerza más suplementación. Siguiendo el procedimiento PRISMA, de los 62 estudios encontrados tan solo 3 cumplieron todos los criterios por lo que fueron analizados en su totalidad para poder ser incluidos en la revisión. La calidad metodológica de los estudios se evaluó mediante la escala PEDro. El estudio de Shomrat et al. (2000) la suplementación con creatina provocó un incremento de la masa corporal y potencia media. El estudio de Burke et al. (2003) obtuvo con la suplementación de creatina incrementos en la fosfocreatina (PCr), creatina total (TCr), fuerza, fibras musculares de tipo II y tejido magro, siendo estos cambios más significativos en las personas vegetarianas. Por último, en el estudio de Burke et al. (2008), el factor de crecimiento insulínico de tipo 1 (IGF-1) se incrementó en un 67%, con mayor acumulación en el grupo que fue suplementado con creatina. A raíz de estos resultados se puede concluir que la suplementación con creatina puede provocar efectos positivos en el rendimiento de los deportistas vegetarianos, ya que puede cubrir ciertas carencias derivadas de la dieta vegetariana.Abstract: The aim of the study was to investigate the effects of strength training plus additional supplementation on non-professional adult athletes who are vegetarian. A systematic review of MEDLINE (PubMed), Scopus, SportDiscus, and WOS (Web of Science) databases was performed following the PICO model, using terms related to vegetarians aged between 18 and 64 years who realized an intervention based on strength training and supplementation. Following the PRISMA statement, of the 62 studies found only 3 met all the inclusion criteria and were analyzed entirely to be included in the review. The methodological quality of the studies was performed using the PEDro scale. The study of Shomrat et al. (2000) with creatine supplementation resulted in an increase in body mass and power. The study of Burke et al. (2003), based on creatine supplementation, obtained an increase of phosphocreatine (PCr), total creatine (TCr), strength, type II muscle fibers, and lean tissue. These changes were significant in vegetarians. Finally, in a study of Burke et al. (2008), insulin-like growth factor-1 (IGF-1) increased by 67%, with higher accumulation in the group that was supplemented with creatine. As a consequence of these results we can conclude that creatine supplementation could have positive effects on the performance of vegetarians due to the fact that it could cover certain shortcomings derived from the vegetarian diet.

In volleyball matches, there are three minute intervals between sets. Therefore, the improvement of the muscle output ratio is one of the most import foundational physical elements for the players. The purpose of this study was to investigate the effects of plyometric training on the changes in electrical signals in the lower limb muscles of male college volleyball players during continuous blocking and to examine the benefits of plyometric training on blocking agility and maximum vertical jump height. In this study, twenty elite male college volleyball players were recruited and divided into a plyometric training group (PTG) and a control group (CG). The wireless electromyography was used for data acquisition, and the electrodes were applied to the left and right rectus femoris, biceps femoris, tibialis anterior, and gastrocnemius. The median frequency was used as the measurement of the electromyographic signals during the jumping blocks. This study used covariate analysis methods, with previously measured results used as covariates to perform a two-way analysis of covariance for the independent samples. Based on the results of this study, after 6 weeks of training, the median frequency of the rectus femoris (2.13% to 4.75% improved) and that of the tibialis anterior muscles (4.14% to 7.71% improved) were significantly lower in the PTG than in the CG. Additionally, the blocking agility increased by 6.26% and the maximum vertical jump height increased by 3.33% in the PTG compared to the CG. The findings provide important insights on the neuromuscular status for volleyball players during continuous blocking jumps. Six weeks of appropriate plyometric training can facilitate the performance of volleyball players.

Participatory Observation

The simulated patient methodology (SPM) is a form of participatory observation and can be used to assess the quality of counselling. The aim is to review those papers reporting the use of the SPM in German community pharmacies (CPs) from the beginning of 2005 to the end of 2018. The reporting items in the study were derived from the PRISMA Statement. We conducted a systematic search in the GVK-Plus, Embase, Web of Science, PubMed and Google Scholar databases. Additional sources included the personal literature collection of 1 of the reviewers and the reference lists from international systematic reviews and potentially relevant papers. The quality of the papers included was evaluated using the AXIS tool. A total of 5 papers were included. The SPM that was used varied greatly in the papers. The quality of counselling was assessed in the papers as being rather poor. The quality of the papers differed for specific assessment criteria. Only an extremely small number of papers could be included, in contrast to other countries. The papers for Germany demonstrate that there is a considerable need for improvement in the quality of counselling in CPs. Also, the deficits identified here for the application of the SPM should be avoided in future papers. It must also be recommended that the SPM be reported in future papers using uniform reporting standards, which are yet to be developed, to ensure better comparability.

Review Protocol

There are no systematic reviews that have identified the existing studies assessing active commuting physical activity (PA) to and from (to/from) school using objective measures, as well as the contribution of both walking and cycling to/from school to PA levels. To fill this gap in the literature, this systematic review will aim (a) to identify existing studies that assess active commuting PA to/from school with objective measures in young people and to examine the contribution of walking and cycling to/from school to PA levels, and (b) to propose an appropriate methodology and practical considerations to assess active commuting PA to/from school based on the studies identified. The review protocol was registered in PROSPERO (CRD42020162004). We will conduct a systematic search up to 2020 in five databases: PubMed, Web of Science, SPORTdiscuss, Cochrane Library, and National Transportation Library. Both the risk of bias and the quality of the identified studies will be evaluated through different instruments according to the design of each study. This systematic review will help to choose the most appropriate objective measures to assess active commuting PA to/from school and to promote walking and cycling to/from school to increase PA levels.

BACKGROUND Preterm birth (PTB) as a common pregnancy complication is responsible for 35% of the 3.1 million pregnancy-related deaths each year and significantly impacts around 15 million children annually across the world. Conventional approaches to predict PTB may neither be applicable for first-time mothers nor possess reliable predictive power. Recently, machine learning (ML) models have shown the potential as an appropriate complementary approach for PTB prediction. OBJECTIVE In this article we systematically reviewed the literature concerned with PTB prediction using ML modeling. METHODS This systematic review was conducted in accordance with the PRISMA statement. A comprehensive search was performed in seven bibliographic databases up until 15 May 2021. The quality of studies was assessed, and the descriptive information including socio-demographic characteristics, ML modeling processes, and model performance were extracted and reported. RESULTS A total of 732 papers were screened through title and abstract. Of these, 23 studies were screened by full text resulting in 13 papers that met the inclusion criteria. CONCLUSIONS We identified various ML models used for different EHR data resulting in a desirable performance for PTB prediction. However, evaluation metrics, software/package used, data size and type, and selected features, and importantly data management method often varied from study to study threatening the reliability and generalizability of the model.

Vertical Jumps

The aim of this study was to describe the intersegmental coordination and segmental contribution during intermittent vertical jumps performed until fatigue. Seven male visited the laboratory on two occasions: 1) the maximum vertical jump height was determined followed by vertical jumps habituation; 2) participants performed intermittent countermovement jumps until fatigue. Kinematic and kinetic variables were recorded. The overall reduction in vertical jump height was 5,5%, while the movement duration increased 10% during the test. The thigh segment angle at movement reversal significantly increased as the exercise progressed. Non-significant effect of fatigue on movement synergy was found for the intersegmental coordination pattern. More than 90% of the intersegmental coordination was explained by one coordination pattern. Thigh rotation contributed the most to the intersegmental coordination pattern, with the trunk second and the shank the least. Therefore, one intersegmental coordination pattern is followed throughout the vertical jumps until fatigue and thigh rotation contributes the most to jump height.

The aim of this study was to perform a systematic review of the literature in order to investigate the effects of the Pilates Method on athletes of different sports. Methods: Researches were carried out in databases (SciELO, LILACS, PubMed, Web of Science and SCOPUS) and to evaluate the methodological quality of the studies, the PEDro scale was used. Results: Of the 87 studies found, only four were included. Meta-analyzes to assess flexibility using the Wells Bank's Sit and Reach test and a fleximeter indicated improvement after Pilates application, although there were no statistically significant differences compared to the control groups (Wells Bank's Sit and Reach test: 2 , 83 95% CI: -0.73 to 6.38, I² = 99%; Fleximeter: -0.78, 95% CI: -1.84 to 0.27, I² = 0%). Conclusion: There is evidence of benefits after Pilates intervention. Future studies with standardized protocols, according to the chosen sport, are necessary to determine how the Pilates Method can improve athletes' performance.
