Efeito do treinamento de lian-gong na capacidade funcional de idosos institucionalizados / Effect of lian-gong training on the functional capacity institucionalized elderly

Introdução: O Lian-Gong é um tipo de ginástica terapêutica que consiste em exercícios simples que estimulam os músculos, tendões e ossos, podendo ocasionar vários benefícios à funcionalidade orgânica de idosos, especialmente os institucionalizados. Objetivos: Identificar o efeito do treinamento de Lian-Gong na capacidade funcional de idosos institucionalizados e caracterizar o perfil dos participantes. Método: A força muscular foi avaliada por meio do teste de levantar e sentar e da capacidade de flexibilidade, utilizando-se o teste de sentar e alcançar, pelo método Lian-Gong composto por seis séries de exercícios, com duração de 24 minutos, dividido em duas partes: prevenção e tratamento de dores no pescoço, ombros, costas, região lombar, glúteos e pernas; e, tratamento e prevenção de dores nas articulações dos membros superiores e inferiores, de tenossinovites e desordens funcionais dos órgãos. O programa de treinamento foi composto por duas sessões semanais, durante oito semanas. Resultados: Participaram do estudo sete idosos. Observou-se que a força muscular apresentou aumentos estatisticamente significantes pós-treinamento (46,6%; p < 0,01), assim como houve aumentos estatisticamente significativos, também na flexibilidade pós treinamento (32,7%; p < 0,01). Conclusão: Os achados do presente estudo sugerem que um programa de oito semanas de treinamento de Lian-Gong é capaz de proporcionar aumento da força muscular e na flexibilidade de pessoas idosas. Recomenda-se a utilização amplamente para idosos institucionalizados, pois contribui para a promoção da saúde osteoneuromuscular

Introduction: Lian-Gong is a type of therapeutic gymnastics that consists of simple exercises that stimulate the muscles, tendons and bones, and can cause several benefits to the organic functionality of the elderly, especially the institutionalized ones. Objectives: To identify the effect of Lian-Gong training on the functional capacity of institutionalized elderly and to characterize the profile of the participants. Method: Muscle strength was assessed by the lifting and sitting test and flexibility capacity, using the sit and reach test, using the Lian-Gong method consisting of six sets of exercises, lasting 24 minutes, divided into two parts: prevention and treatment of pain in the neck, shoulders, back, lumbar region, glutes and legs; and, treatment and prevention of pain in the joints of the upper and lower limbs, tenosynovitis and functional disorders of the organs. The training program consisted of two weekly sessions for eight weeks. Results: Seven elderly participated in the study. It was observed that muscle strength showed statistically significant increases post-training (46.6%; p < 0.01), as well as statistically significant increases in post-training flexibility (32.7%; p < 0.01). Conclusion: The findings of the present study suggest that an eight-week Lian-Gong training program is able to provide increased muscle strength and flexibility in older people. It is recommended to use widely for institutionalized elderly, as it contributes to the promotion of musculoskeletal health

Exercício de força combinado à restrição de fluxo sanguíneo induz aumentos agudos na pressão arterial sistólica / Strength exercise combined to blood flow restriction induces acute increases in systolic blood pressure

Recentemente cresceu o número de pesquisas sobre o exercício de força (EF) de baixa intensidade (20-50% de 1RM) combinado à restrição do fluxo sanguíneo (RFS), mostrando adaptações semelhantes ao EF de alta intensidade. Entretanto, muitas questões sobre essa metodologia necessitam ser investigadas. O objetivo desse estudo foi analisar a resposta aguda da pressão arterial em repouso e durante o EF combinado à RFS. Dezesseis jovens (22±2 anos de idade), ativos e de ambos os sexos, realizaram o EF em duas diferentes condições, separadas por um intervalo de 48h: 1) Exercício isolado (EF) e 2) Exercício combinado à RFS (EF+RFS, 100 mmHg, porção proximal da coxa, mantida durante o exercício). Ambos realizaram 3 séries no exercício leg press com o membro dominante, à 30% de 1RM, 1 minuto de descanso, duração de 90 segundos cada série e cadência de 2 segundos, totalizando 22 repetições para a fase concêntrica e 23 para a fase excêntrica do movimento. Foram avaliadas a pressão arterial sistólica (PAS), diastólica (PAD), frequência cardíaca (FC), duplo produto (DP) e lactato sanguíneo nos momentos: repouso e imediatamente após o exercício. Foi observado apenas aumento significativo da PAS e do DP em repouso e da PAS durante o EF+RFS. O lactato sanguíneo não se alterou em nenhuma condição avaliada. Concluindo que o exercício de força com restrição de fluxo sanguíneo apresentou maiores respostas de pressão arterial sistólica em repouso e durante o exercício em sujeitos jovens ativos...(AU)

Recently, the number of researches about the strength exercise (SE) of low intensity (20- 50% of 1RM) combined to the blood flow restriction (BFR) increased, showing similar adaptations to the high-intensity SE. However, many questions about this methodology need be investigated. The purpose of this study was to analyze the acute response of blood pressure at rest and during SE combined with BFR. Sixteen young subjects (22 ± 2 years old), actives and of both sexs, underwent SE in two different conditions, separated by an interval of 48h: 1) isolated strength exercise (SE) and 2) strength exercise combined to BFR (SE+BFR, 100 mmHg, proximal portion of the thigh, maintained throughout the exercise session). Both conditions performed 3 sets on the leg press exercise with the dominant leg, with 30% of 1RM, 1 minute of rest, each series with 90 seconds of the duration and movement cadence of the 2 seconds, totaling 22 repetitions in the concentric phase and 23 in the eccentric phase of movement. Systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), double product (DP) and blood lactate were evaluated on rest and immediately after exercise moments. It was observed only significant increase in SBP and DP at rest and SBP during SE+BFR condition. Blood lactate did not change in any condition evaluated. Concluding that strength exercise with blood flow restriction showed higher responses of systolic blood pressure at rest and during exercise in active young subjects...(AU)

Effects of controlled doses of Oxyelite Pro on physical performance in rats.

BACKGROUND: OxyElite Pro (OEP) is a dietary supplement to increase metabolism which contains as key stimulant the ingredient 1,3-dimethylamylamine (DMAA). Serious adverse effects have been reported after OEP consumption however, these effects are related to poisoning or overdose. To our knowledge, no one studied the effects of OEP at controlled doses. Thus, the aim of this study was to evaluate acute and chronic OEP affects, at controlled doses in Wistar rats, on physical performance, metabolic parameters, liver injury markers and oxidative stress markers and mitochondrial biogenesis in skeletal muscle. METHODS: Rats were divided in control, 4.3 mg OEP/kg, 12.9 mg OEP/kg and 25.8 mg OEP/kg. All groups were submitted to supplementation with OEP for 4 weeks and the experimental protocols were performed 30 min after the first OEP administration (acute response) and 30 min after the last OEP administration at the end of the forth week (chronic response). RESULTS: Running distance and running time increased after acute administration of 12.9 mg OEP/kg (2.6-fold) and 25.8 mg OEP/kg (2.8-fold). Since no effect on the exercise tolerance test was observed at the lower OEP dose (4.3 mg OEP/kg), this group was removed from further analyzes. On other hand, running distance and running time decreased after daily supplementation for 4 weeks also in both groups (64% in 12.9 mg OEP/kg and 72% in 25.8 mg OEP/kg). Chronic supplementation at both 12.9 and 25.8 mg OEP/kg decreased TBARS levels in soleus muscle (36 and 31%) and liver (43 and 25%). AOPP was also decreased by both doses in the liver (39 and 45%). Chronic administration of the highest dose, 25.8 mg OEP/kg, was able to reduce mRNA expression of PGC-1α in soleus muscle (25%). No effect was found in other analyses such as spontaneous physical activity, body weight, food and water intake, hepatic toxicity, cardiac oxidative stress and mitochondrial DNA amount. CONCLUSION: Maximum and not recommended doses of OEP ingested acutely presented stimulating effect on the ability to exercise. However, its daily consumption for 4 weeks showed antioxidant effects in soleus muscle and liver which may have decreased the PGC-1α mRNA expression on soleus muscle and contributed to the impaired performance in the exercise tolerance test.
