Efetividade do treinamento de resistência à fadiga dos músculos dos membros inferiores dentro e fora d'água no equilÃbrio estático e dinâmico de idosos Effectiveness of aquatic and non-aquatic lower limb muscle endurance training in the static and dynamic balance of elderly people
CONTEXTUALIZAÇÃO: O envelhecimento compromete a habilidade do sistema nervoso central (SNC) de realizar a manutenção do equilÃbrio corporal bem como diminui a capacidade das reações adaptativas. Para prevenir as quedas, é necessário aprimorar as condições de recepção de informações sensoriais. OBJETIVOS: Comparar o impacto de um programa estruturado de exercÃcios de resistência muscular dos membros inferiores dentro e fora d'água no equilÃbrio estático e dinâmico em idosos. MÉTODOS: Trata-se de um estudo clÃnico, prospectivo, aleatório, em que as variáveis utilizadas foram avaliadas antes e após o programa de treinamento. Foram avaliados 36 idosos por meio de quatro testes: Escala de EquilÃbrio de Berg, Dynamic Gait Index, velocidade da marcha, Marcha Tandem. Posteriormente, houve a alocação dos voluntários em três grupos: grupo de exercÃcio na piscina terapêutica, grupo de exercÃcio no solo e grupo controle. Os grupos de exercÃcios foram submetidos a um programa de resistência muscular dos membros inferiores aplicado durante seis semanas, duas sessões semanais com 40 minutos de duração. Os voluntários foram reavaliados após seis semanas. Os dados foram analisados estatisticamente pelo teste ANOVA univariada para comparação entre os três grupos antes e após a intervenção. RESULTADOS: O programa de resistência muscular dos membros inferiores promoveu aumento significativo do equilÃbrio dos idosos (p<0,05) nos testes avaliados após o programa de treinamento. CONCLUSÃO: O programa de resistência muscular proporcionou uma melhora significativa no equilÃbrio estático e dinâmico de idosos comunitários. Foi possÃvel inferir também que essa melhora ocorreu independentemente do meio em que o programa foi realizado, ou seja, se dentro ou fora d'água.<br>BACKGROUND: Aging compromises the ability of the central nervous system to maintain body balance and reduces the capacity for adaptive reactions. To prevent falls, the reception conditions for sensory information need to be improved. OBJECTIVES: To evaluate the impact of a structured aquatic and a non-aquatic exercise program for lower-limb muscle endurance on the static and dynamic balance of elderly people. METHODS: This was a prospective randomized clinical study in which the variables were assessed before and after the training program. Thirty-six elderly people were evaluated using four tests: the Berg Balance Scale, Dynamic Gait Index, gait speed and tandem gait. The participants were randomized into three groups: aquatic exercise group, non-aquatic exercise group and control group. The exercise groups underwent a program for lower-limb muscle endurance that consisted of 40-minute sessions twice a week for six weeks. The participants were reevaluated after six weeks. The data were analyzed statistically using the univariate ANOVA test for comparisons between the groups before and after the intervention. RESULTS: The program for lower-limb muscle endurance significantly increased balance (p<0.05) in the evaluation tests after the training program. CONCLUSION: The muscle endurance program provided a significant improvement in static and dynamic balance among community-dwelling elderly people. It was also possible to infer that this improvement occurred regardless of the environment, i.e. aquatic or non-aquatic
Efficacy of whole-body vibration training on brain-derived neurotrophic factor, clinical and functional outcomes, and quality of life in women with fibromyalgia syndrome: a randomized controlled trial
Whole-body vibration (WBV) is an exercise modality or treatment/prophylaxis method in
which subjects (humans, animals, or cells) are exposed to mechanical vibrations through a vibrating
platform or device. The vibrations are defined by their direction, frequency, magnitude, duration, and

the number of daily bouts. Subjects can be exposed while performing exercises, hold postures, sitting,
or lying down. Worldwide, WBV has attracted significant attention, and the number of studies is
rising. To interpret, compare, and aggregate studies, the correct, complete, and consistent reporting
of WBV-specific data (WBV parameters) is critical. Specific reporting guidelines aid in accomplishing
this goal. There was a need to expand existing guidelines because of continuous developments
in the field of WBV research, including but not limited to new outcome measures regarding brain
function and cognition, modified designs WBV platforms and attachments (e.g., mounting a chair
on a platform), and comparisons of animal and cell culture studies with human studies. Based
on Delphi studies among experts and using EQUATOR recommendations, we have developed
extended reporting guidelines with checklists for human and animal/cell culture research, including
information on devices, vibrations, administration, general protocol, and subjects. In addition, we
provide explanations and examples of how to report. These new reporting guidelines are specific to
WBV variables and do not target research designs in general. Researchers are encouraged to use the
new WBV guidelines in addition to general design-specific guideline
