The ability to generate muscle strength in the lower limbs (LLLS) is one of the most important predictors of functional status in the elderly and is directly related to falls and fractures. The vertical countermovement jump (CMJ) is a fundamental motor skill in the accomplishment of many activities, since it demands a coordinated performance of the body with muscular recruitment. We searched the databases: PubMed, Bireme, SciELo and PEDro. The keywords were selected according to the Health Sciences Descriptors (DeCS) to address the use of CMJ in the elderly. From 39 studies found, 11 were selected and evaluated by the PEDro scale and presented good methodological quality. The vertical countermovement jump proved to be useful in the evaluation of strength and power in the elderly. [ABSTRACT FROM AUTHOR]

Starting from the results individual suggestions were offered for the training of this athletes.

O salto vertical tem sido destacado na literatura como principal método de medida de força explosiva de membros inferiores para desportistas e sujeitos fisicamente ativos. De fato, esta ação motora é parte integrante de modalidades como voleibol, handebol, futebol, basquetebol e determinadas provas de atletismo. O objetivo é avaliar e compara em dois saltos vertical, conhecido como SARGENT JUMP TEST. Foram avaliados 12 atletas femininas de futebol e futsal, da Escola Estadual Padre Giuseppe Pisoni da cidade de Rio Grande da Serra, São Paulo, em fase de treinamento. As atletas tem idade média entre 14 e 17 anos. Após a familiarização do teste, foi avaliada a impulsão vertical. Os resultados do estudo teve uma diferença entre os saltos e a média obtida para o primeiro salto foi de 0,24 cm e para o segundo salto foi de 0,34 cm de atletas de futebol e futsal. Além disso, para as categorias femininas, não há muitos dados na literatura para posteriores consultas. Esses parâmetros são importantes nos treinos, para que o treinador possa acompanhar o desempenho das atletas submetidas na avaliação. Em conclusão, houve um pequeno aumento do salto vertical com os dados obtido nos dois testes, e nos treinos uma significativa melhora do desempenho. ABSTRACT Analysis of vertical jump in the elementary school athletes of the sub-15 to sub-17 feminine from Rio Grande da Serra, São Paulo The vertical jump has been highlighted in the literature as a primary method of measurement of power of lower limbs for athletes and physically active subjects. In fact, this is integral to motor action sports such as volleyball, handball, football, basketball and athletics certain part. The aim was to evaluate and compare two vertical jumps, known as JUMP TEST SARGENT. 12 female athletes football and futsal , Escola Estadual Padre Giuseppe Pisoni from Rio Grande da Serra, Sao Paulo were evaluated in the training phase. The athletes have an average age between 14 and 17 years. After familiarization test, the vertical jump was assessed. The study results had a difference between the heels and the average score for the first jump was 0.24cm and the second jump was 0.34cm of football and futsal.

El propósito de esta investigación ha sido comprobar el efecto de la intensidad del contramovimiento sobre el rendimiento del salto vertical. Para el control de la intensidad se han utilizado tres protocolos de saltos verticales con participación de brazos: a) saltos verticales partiendo desde la posición de erguidos (CMJ + S); b) partiendo de un salto previo donde la altura de caída estaba regulada por el participante (DJ-AR), y c) partiendo de un salto previo máximo (DJ-M). Han participado 28 deportistas practicantes de modalidades deportivas donde el salto vertical constituye una habilidad básica. Se ha utilizado una plataforma de fuerza, operando a 500 Hz, sincronizada temporalmente a una cámara de vídeo, que registraba a 210 Hz el plano sagital de los saltos realizados sobre la plataforma. La aceleración vertical del CM se determinó a partir de la fuerza neta vertical y la masa del saltador. A continuación, los sucesivos registros de la velocidad vertical y las posiciones de componente vertical adoptadas por el CM se determinaron mediante integración de las componentes verticales de las funciones de aceleración-tiempo y velocidad-tiempo, respectivamente. Las constantes de integración se determinaron mediante imágenes de vídeo (2D). Los resultados han puesto de manifiesto que, cuando se realizan saltos con alturas de caída superiores a 0,39 ± 0,05 m, el pico de potencia durante la fase propulsiva (PP(propulsiva)), el impulso vertical de propulsión (Iv(propulsión.)), y la altura de salto (Ycm vuelo), se reducen de forma significativa (p

O objetivo do presente estudo foi analisar a influência de diferentes profundidades de agachamento no desempenho e em parâmetros biomecânicos no salto com contra movimento (CMJ). Participaram do estudo 22 atletas de voleibol ou basquetebol do sexo masculino, participantes de competições em nível regional e universitário. Os CMJ foram realizados em três condições: 1) com flexão relativa do joelho ao final da fase de contra movimento menor que 90° (CMJ90°) e; 3) posição preferida (CMJPREF). Durante os CMJ foram mensurados: altura do salto, variáveis cinemáticas, cinéticas e eletromiográficas. ANOVA para medidas repetidas com post-hoc de Bonferroni foi utilizado na comparação das variáveis, adotando-se nível de significância de p≤0,05. O desempenho foi maior na situação PREF e 90°. A potência média e pico, a força máxima normalizada e absoluta, apresentaram os maiores valores na posição >90°. O pico de velocidade e as velocidades angulares de quadril e joelho apresentaram os maiores valores na posição 90°. Os músculos reto femoral e bíceps braquial não apresentaram diferença entre as condições. Conclui-se que o desempenho e as variáveis biomecânicas analisadas no CMJ são influenciados pelo nível de flexão do joelho. As maiores alturas foram obtidas nos saltos realizados a partir de uma maior profundidade de agachamento, assim, tal estratégia técnica poderia ser utilizada por atletas a fim de otimizar a altura do salto vertical nos treinamentos e competições.

To study reliability of vertical jump (VJ) is to test the consistency of this measure to certify the quality of the data. The aim of this study was verify the stability of three different techniques of VJ. Twenty two men (22,5 ± 2,7 years; 174,3 ± 7,0 cm; 71,3 ± 8,2 kg) was tested in four occasions. The VJ carried through in the present study was squat jump (SJ), drop jump (DJ) and countermovement jump (CMJ). The first visit was used for familiarization. The subsequent visits served to collect the data of VJ in a jump platform. Four maximum jumps of each model of VJ was executed in all the visits of random form, with worst jump had been discarded of each different techniques of SV. The intervals between jumps was 45 s and between the different techniques VJ was 5 min. The variable measured were height of the jump, peak power absolute and relative to body mass. For the DJ, beyond the variable already cited, were collected the contact time, flight time and reactive strength index. To test the reliability the CCI were used. LA95% proposed by Bland-Altman was used to identify random error and a ANOVA with repeated measures followed by Bonferroni post hoc test was used to observe the systematic bias. The results had demonstrated high reliability and lower random error and systematic bias for all variables tested. The VJ are reliability measurement tools to evaluate the height of the jump, the muscular power and the reactive strength of the inferior members.

Resumen El objetivo de este estudio fue valorar la disminución de la altura de salto en el test CMJ antes, durante y después de la competición en nueve jóvenes jugadores internacionales de baloncesto. Del mismo modo, se analizó la relación entre los minutos que cada jugador permanecía en cancha y la disminución de la capacidad de salto. Para ello, se evaluó la altura de salto mediante el CMJ en 8 momentos diferentes (antes y después del calentamiento, durante el descanso, inmediatamente después del partido y en los minutos 1’, 3’, 5’ y 7’ tras la finalización del encuentro) utilizando una plataforma de contacto. Para estimar la presencia de diferencias significativas entre los momentos se utilizó el análisis de la varianza (ANOVA) de una cola. Los resultados demuestran que la capacidad de salto empeoró progresivamente durante la competición (F = 89.29, p = 0), descendiendo durante el descanso de 52.7 cm a 50.2 cm (p < 0.05) y con valores de salto tras la finalización del partido de 49.0 cm (p < 0.05). Así mismo, la altura de salto fue disminuyendo después del final del partido, alcanzándose en la última toma (7’ después del final del partido) el peor resultado (42.2 ± 2.4 cm), lo cual supuso un descenso del rendimiento del 19.8 ±4.8 %. Por otro lado, no se observaron correlaciones significativas entre el tiempo en pista y la disminución de la capacidad de salto. La capacidad de salto de los jugadores se deteriora progresivamente durante y después de la competición.abstract The main aim of this study was to assess the decrease in jump height in CMJ test before, during and after competition in international youth basketball. Equally, we examined the relationship between minutes played and the decline in jump capacity during the course of the match. To do this, we evaluated the jump height in CMJ by eight different times (before and after warm up, at rest, immediately after the game and within minutes 1', 3', 5 'and 7' after completion of the competition) using a contact platform. To estimate the presence of significant differences between the times we used a one – way analysis of variance (ANOVA). The results showed, that the jumping capacity decreased during competition (F = 89.29, p = 0), decrease during the rest of 52.7 cm to 50.2 cm (p < 0.05) and after completion of the match from 49.0 cm (p < 0.05). Similarly, jump height was decreased after the end of the match, reaching at the last measurement (7 'after the end of the competition) the worst result (42.2 ± 2.4 cm), which was a yield decrease of 19.8 ± 4.8 %. On the other hand, there was not correlation between play time and performance decline. The maximal jump capacity decreased during and after competition.

ResumenEl rendimiento en acciones explosivas como el golpeo de balón y el salto vertical es de gran relevancia en el fútbol. Los objetivos del presente estudio fueron: 1) Estudiar la secuencia del golpeo en futbolistas jóvenes de alto nivel, y, 2) analizar las posibles relaciones existentes entre el golpeo de balón y el salto vertical. 21 jugadores de alto nivel (16,1 ± 0,2 años) llevaron a cabo un test de salto vertical con contramovimiento (CMJ) y un test de golpeo de balón con la máxima potencia. Los datos fueron registrados mediante una plataforma de fuerzas (Dinascan IBV) y un sistema de captura automática del movimiento (Vicon). Con este estudio, se aporta información sobre la cinemática del golpeo en futbolistas juveniles de alto nivel. En función de los resultados obtenidos, se puede afirmar que la secuencia temporal de máximos de velocidad sucede desde el extremo más proximal al más distal, incrementándose la velocidad. La ausencia de relación entre el golpeo y el salto sugiere el trabajo de fuerza explosiva específico para la mejora de cada una de ellas.AbstractKicking and vertical jumping performance are very important in soccer. The aims of the present study were: 1) To study the kinematical sequence of the soccer kick in young top-class soccer players, and, 2) to analyse the possible relationships among the different parameters related to the soccer kick and the vertical jump in this population. 21 top-class soccer players (16,1 ± 0,2 yr.) performed a countermovement jump test (CMJ) and a maximum power soccer kick test. Data was obtained from a Dinascan IBV force platform and the Vicon system of automatic capture of the movement. With this study, we added data on the kinematics of soccer kick in young top-class soccer players. With the results obtained, it is possible to deduce that the temporal sequence of maximum velocities begins from the more proximal to more distal joint, increases the velocity. The absence of relation between these actions suggests the need of a specific explosive strength training for the improvement of each one of them.

El objetivo de este estudio fue comparar los efectos del entrenamiento con electroestimulación neuromuscular (EENM) concéntrica frente al entrenamiento voluntario. 28 estudiantes fueron divididos en tres grupos: EENM (GE; n = 10), entrenamiento voluntario (GV; n = 8) y grupo control (GC; n = 10). Se realizaron 16 entrenamientos del cuádriceps en 4 semanas. Cada sesión consistió en 8 series de 10 repeticiones al 80% de la fuerza máxima isométrica (FMI) en una máquina de extensión de cuádriceps. El ritmo de ejecución fue de 1:1:1 (fases concéntrica, excéntrica y reposo, respectivamente). Al GE se le aplicaba EENM durante la fase concéntrica. Antes y después del entrenamiento (T1 y T2, respectivamente) y tras dos semanas de desentrenamiento (T3) se midió el tiempo de carrera en 20 m (T-20), tres saltos verticales (SJ, CMJ y ABK) y la FMI. Entre T1 y T2 se produjo un incremento significativo de la FMI tanto en GE como en GV (39,2 % y 30,1 %, p

El objetivo del presente estudio fue determinar el efecto agudo de una exposición a vibraciones mecánicas sobre la fuerza desarrollada en un salto vertical. Un total de 15 sujetos sanos y activos (11 hombres y 4 mujeres) se sometieron a 60 s de estimulación sobre una plataforma vibratoria que indujo oscilaciones verticales (frecuencia: 50 Hz; amplitud: 2 mm). Antes del periodo de estimulación vibratoria así como 30 s y 2 min después del mismo, los sujetos realizaron un salto vertical (squat jump) sobre una plataforma de contactos, a partir de la cual se registró el tiempo de vuelo (tv) y la altura (h) de cada salto. Los resultados obtenidos muestran un efecto positivo del estímulo vibratorio sobre la fuerza desarrollada en el salto vertical realizado 2 min después de la vibración, ya que tanto tv como h aumentaron significativamente respecto a los valores obtenidos en el primer salto. Se puede concluir, por tanto, que una estimulación de 60 s sobre plataforma vibratoria combinando altas frecuencias y bajas amplitudes en su oscilación, genera un efecto residual positivo en la capacidad de salto vertical.

Con el propósito de analizar los cambios de la fuerza máxima explosiva en relación a la ejecución de series de salto vertical repetido (SVR) con periodos cortos de recuperación pasiva en jugadores de baloncesto, se evaluaron 12 deportistas en un protocolo de cuatro series (S) de 15-s de saltos verticales con 10-s de recuperación entre S. Se midieron la altura de salto inicial (ASI) y final (ASF) de cada S; se utilizó ANOVA de una vía con post hoc de Bonferroni para el análisis de las diferencias ASF-ASI por S y una prueba t de Student para analizar el índice de fatiga (IF) por serie. Se encontró que la diferencia ASF-ASI fue progresivamente incremental desde la S1 hasta la S4 (-2,8 ±6,2 cm, -6,8 ±4,9 cm, -8,4 ±5,6 cm y -9,3 ±5,9 cm, respectivamente), aunque la diferencia fue mayor solo en S4 con respecto a S1 (p=0,014). Es posible que los períodos de recuperación entre cada S influyeron en el mantenimiento de la fuerza muscular explosiva (FME) durante los primeros 45-s de saltos, sin embargo, la suma de estas ejecuciones generó un aumento de la fatiga al final de la prueba. La FME puede ser afectada por la suma de ejecuciones de SVR aun con la inclusión de períodos cortos de recuperación entre series. La relación trabajo-recuperación en baloncesto es un factor que debe considerarse para planificar el entrenamiento en jugadores de baloncesto.

Estudar confiabilidade do salto vertical (SV) é testar a consistência dessa medida para atestar a qualidade dos dados. O objetivo do estudo foi verificar a estabilidade de três diferentes técnicas de SV. Vinte dois homens (22,5±2,7 anos; 174,3±7,0 cm; 71,3±8,2 kg) foram testados em quatro ocasiões. Os SV realizadas no presente estudo foram salto agachado (SA), salto profundo (SP) e salto contra movimento (SCM). A primeira visita foi usada para familiarização. As visitas subsequentes serviram para coletar os dados dos SV em uma plataforma de salto. Quatro saltos máximos de cada modelo de SV foram executados em todas as visitas de forma aleatória, com descarte do pior resultado de cada modelo de SV. O intervalo entre os saltos foi de 45 s e entre os tipos de SV de 5 min. As variáveis mensuradas foram altura do salto, pico de potência absoluta e relativa a massa corporal. Para o SP, além das variáveis citadas também foram analisadas o tempo de contato, tempo de voo e índice de força reativa. Para testar a confiabilidade foi utilizado o CCI. O LC95% proposto por Bland-Altman foi usado para identificar erro randômico e uma ANOVA com medidas repetidas seguida pelo teste post hoc de Bonferroni foi utilizado para observar o erro sistêmico. Os resultados encontrados demonstraram uma alta confiabilidade e baixo erro randômico e sistemático para todas as variáveis testadas. Os SV são ferramentas confiáveis para avaliar a altura do salto, a potência muscular e a força reativa dos membros inferiores.

This study aimed to verify the acute effect of flexibility exercise in the power of the lower limbs. Eighteen men were included, randomly assigned to groups, Proprioceptive Neuromuscular Facilitation (FNP, 23 ± 6.8 years), active (TA, 23.3 ± 4.2 years) and Passive (TP, 28.5 ± 12.9 years). To verify the strength in the lower limbs was used Sargent Jump Test before and post intervention. The Anova Two way for repeated measures was applied, which compared the values of Vertical Jump before and after flexibility exercises. All groups showed a reduction in vertical jump performance, however the results were significant only in TA groups (pre = 0.43 versus post = 0.41 cm; Δ% = - 4.99%; p = .007) and TP (Pre = 0.46 = 0.43 cm vs Post, Δ% = -7.01%, p = .012). In FNP group, the values were not significant (pre = 0.47 versus post = 0.46 cm; Δ% = - 3.27%; p = .709). It was possible to verify that the flexibility exercise exerted a negative influence on the performance of the muscular power of the lower limbs, and the training of proprioceptive neuromuscular facilitation promoted lower rates of reduction in the average height of the jump.
