ABSTRACT

Vários métodos de aquecimento têm sido empregados no campo do treinamento esportivo . O foam rolling (FR) é uma das técnicas mais populares. No entanto, permanece o esclarecimento so bre o s períodos ótimos de FR para melhorar ou manter o desempenho. Portanto, o objetivo do presente estudo foi explorar o efeito agudo de diferentes períodos do FR no desempenho do salto vertical contramov iment o (SV). Doze indivíduos recreacionalmente ativos (23,92 ± 4,08 anos, 7 0 ± 1 2 k g, 1 71 ± 8 cm ) fo ram voluntários para o estudo. Todos os participantes completaram todos os protocolos ex perim en tais co m entrada randomizada. Os participantes realizaram seis visitas separadas por 48 horas. A primeira sessão incluiu a coleta de dados antropométricos, familiarização com o FR e a técnica do SV. Em seguida, cin co protocolos experimentais foram executados em ordem aleatória: Protocolo controle (PC) - salto v ertical sem FR; P30 ­ uma série de 30 segundos de FR antes do salto vertical; P60 - duas séries de 30 segun do s de FR; P90: três séries de 30 segundos de FR; P120 ­ quatro séries de 30 segundos de FR. O FR foi implementado para quadríceps, isquiotibiais, glúteo e gastrocnêmio. Diferenças significativas no desempenho do salto vertical (p <0,012) foram observadas no P30 (47,4 ± 11,7 cm), P60 (48,9 ± 11,9 cm), P90 (48,5 ± 12,1cm), P120 (48,6 ± 11,3 cm) em relação à PC (46,8 ± 11,3 cm). Além disso , P 60, P9 0, P120 apresentaram maior desempenho de salto vertical em relação ao p rotocolo P3 0. Po rtanto , o s praticantes e treinadores devem considerar a utilização de 60-120 segundos de FR durante o aquecimento, com o objetivo de melhorar o desempenho do SV...(AU)


Several warm-up methods have been employed in the field of athletic training. Th e foam rolling (FR) is one of the most popular techniques; however, there is still a lack o f ev idence abo ut t he optimal FR periods to enhance strength performance. Therefore, the purpose of the present study was t o explore the acute effect of different periods of the FR on vertical countermovement jump. Twelve recreationally active individuals (23.92 ± 4.08 years, 70 ± 12 kg, 171 ± 8cm) volunteered for t he st udy . Treatment conditions were participants using a random assignment. Participan ts p erform ed six v isit s separated by 48 hours. The first session included the collection of anthropometric data and familiarizatio n with a foam roller and the vertical countermovement jump technique. Then, five experimental p rotocols were employed in a randomized order: control protocol (CP) - the vertical countermovement without FR; P30 - one set of 30 seconds of FR before the vertical jump; P60 - two sets of 30 seconds of FR; P90: three sets of 30 seconds of FR; P120 - four sets of 30 seconds of FR. The FR was implemented for quadriceps, hamstrings, gluteus, and gastrocnemius. Significant differences in vertical countermovement jump performance (p < 0.012) were observed under the P30 (47.4 ± 11.7 cm), P60 (48.9 ± 11.9 cm), P90 (48.5 ± 12.1), P120 (48.6 ± 11.3 cm) compared to CP (46.8 ± 11.3 cm). In addit io n, P60 , P 90 , P 12 0 sh o wed greater vertical jump performance compared to the P30 protocol. Therefore, t he p ractition ers sh o uld consider utilizing 60-120 seconds of FR during the warm-up with the goal of acutely improving the vertical countermovement jump performance...(AU)

ABSTRACT

A variável força muscular (FM) na prática esportiva, sobretudo no futebol, é de extrema importância em atividades como chutes, disputas de bola, arrancadas e saltos. Além disso, permite identificar indivíduos que estão em grupos de risco para lesões. Assim, técnicas, como a auto liberação miofascial (ALM), vêm sendo utilizadas para o aprimoramento do desempenho esportivo e para prevenir lesões. OBJETIVO: Verificar o efeito crônico da ALM na FM em atletas de futebol feminino. METODOLOGIA: Este estudo trata-se de um ensaio clínico randomizado. Participaram do estudo 14 atletas de futebol feminino. Inicialmente foram realizadas avaliações no aparelho dinamômetro isocinético dos extensores e flexores de joelho. As participantes foram divididas em dois grupos, um grupo intervenção (GI) e um grupo controle (GC). As participantes do GI realizaram um aquecimento associado à ALM com um foam roller. Já as participantes do GC, realizaram o mesmo aquecimento, porém sem a associação da ALM. Após 48 horas da última intervenção, foi realizada uma reavaliação no aparelho dinamômetro isocinético. RESULTADOS: Não foram verificados efeitos significativos entre os grupos no pós-teste. Na comparação pré e pós-teste entre os grupos, houve uma piora significativa na variável pico de torque de extensão do membro inferior dominante no grupo que não fez a ALM (p = 0,013). CONCLUSÃO: Conclui-se que uma abordagem crônica de ALM não foi capaz de gerar mudanças significativas na FM dos extensores e flexores de joelho. Mais estudos são necessários para apoiar esses achados. Registro ReBEC: RBR-7qnxty.


The variable muscle strength (MS) in sports practice, especially in football, is extremely important in activities such as kicks, ball disputes, sprints and jumps. In addition, it allows identifying individuals who are at risk groups for injuries. Thus, techniques, such as selfmyofascial release (SMF), have been used to improve sports performance and to prevent injuries. OBJECTIVE: To verify the chronic effect of SMF on MS in female soccer athletes. METHODOLOGY: This study is a randomized clinical trial. 14 female soccer athletes participated in the study. Initially, evaluations were performed on the isokinetic dynamometer device of knee extensors and flexors. The participants were divided into two groups, an intervention group (IG) and a control group (CG). IG participants performed a warm-up associated with SMF with a foam roller. CG participants, on the other hand, performed the same warm-up, but without the association of SMF. 48 hours after the last intervention, a reassessment was performed on the isokinetic dynamometer device. RESULTS: There were no significant effects between groups in the post-test. In the pre- and post-test comparison between the groups, there was a significant worsening in the peak torque variable of the dominant lower limb extension in the group that did not perform SMF (p = 0.013). CONCLUSION: It is concluded that a chronic SMF approach was not able to generate significant changes in the MS of knee extensors and flexors. Further studies are needed to support these findings.

ABSTRACT

Introdução: A autoliberação miofascial com o Foam Roller (FR) ou Roller Massager (RM) pode ser uma intervenção que favorece a recuperação após exercícios. Objetivo: Revisar de forma integrativa os efeitos do FR ou RM sobre a dor e a funcionalidade musculoesquelética de voluntários saudáveis após a realização de exercícios. Métodos: Revisão integrativa da literatura. A busca foi realizada nas bases de dados Medline (PubMed), Cochrane Library, Biblioteca Virtual em Saúde e PeDro, sem restrições de ano de publicação ou idioma, através dos descritores em inglês "Healthy Volunteers"; "Exercise"; "Clinical Trial"; e das palavras-chave "Myofascial Release", "Foam Rolling", "Roller Massage". Resultados: Inicialmente a busca incluiu 84 estudos e posterior análise dos critérios de elegibilidade foram incluídos apenas quatro estudos. Nestes estudos a intervenção melhorou a percepção da dor e algumas variáveis funcionais, dentre estas, a amplitude de movimento, força, resistência, velocidade de reação e a potência após os exercícios. Conclusão: Os estudos demonstram que o FR ou RM reduziram a dor e melhoram algumas variáveis funcionais. No entanto, estes resultados ainda são inconsistentes pelo baixo número de estudos, carecendo de maior investigação para aumentar o nível de evidência e a aplicação da técnica nesta condição. (AU)


Introduction: Self-myofascial release with the Foam Roller (FR) or Roller Massager (RM) may be an intervention that favors recovery after exercise. Objective: To review in an integrative way the effects of FR or RM on pain and musculoskeletal function of healthy volunteers after exercise. Methods: Integrative literature review. The study was performed in the databases Medline (PubMed), Cochrane Library, Virtual Health Library and PeDro, without restrictions of year of publication or language, through the English descriptors "healthy volunteers"; "exercise"; "clinical trial"; and the key words "myofascial release", "foam rolling", "roller massage". Results: Initially the search included 84 studies and subsequent analysis of the eligibility criteria, only four studies were included. In these studies, the intervention improved the perception of pain and some functional variables, among them, the range of motion, strength, resistance, reaction speed and power after exercise. Conclusion: Studies show that FR or RM reduced pain and improved some functional variables. However, these results are still inconsistent due to the low number of studies, requiring further investigation to increase the level of evidence and the application of the technique in this condition.

ABSTRACT

PURPOSE: This study compared the effectiveness of three methods, fascial distortion model (FDM), myofascial release (MFR), self-myofascial release (SMR), on the neck range of motion and pain. METHODS: In this study, the collected data were processed statistically using SPSS version 22.0 for Windows. Descriptive statistics were used to analyze the general characteristics of the subjects. Repeated measure ANOVA was conducted to analyze the range of motion of the neck of the group and VAS, and Contras was used to see the difference in significance over time. One-way ANOVA was used to compare the differences among the groups and a post-hoc test was used. The significance level (α) was 0.05. RESULTS: In the range of motion, the flexion and extension of the neck, right rotation, and left rotation were significantly different in the SMR, FDM, and MFR groups. The right lateral flexion showed significant differences in the FDM, MFR, and SMR groups. The VAS was similar in the groups at 2 and 4 weeks, but there was a significant difference among the FDM, MFR, and SMR groups at 6 weeks. CONCLUSION: In this study, MFR and MSR as well as FDM were effective in controlling the range of motion and pain control of the neck. Further studies will be needed to determine the effects of long-lasting treatments other than pain control. These studies and the present study will be used as a basis for ongoing research into the duration and method of application for musculoskeletal therapies.
