AIM: Study of the effect of taking a complex biologically active food supplement with calcium and vitamins D3 and B6 to the effectiveness and duration of medical rehabilitation effect at patients with osteoporosis and with a high risk of fractures. MATERIAL AND METHODS: We examined 119 men and women with osteoporosis and (or) with a high risk of fractures, beginning a course of medical rehabilitation. The 1st study group (SG1) included 41 patients who had already received antiresorptive therapy. In SG2 and SG3, 39 patients who did not receive pathogenetic therapy of osteoporosis were included by the randomization method. For patients SG1 and SG2, a complex biologically active food supplement Osteomed forte was prescribed to use within 12 months. The dynamics of tensodynamometry, stabilometry and functional tests were evaluated in 20 days, 6 and 12 months after the start of the study. RESULTS: The muscle strength indicators achieved during the 20-day training session compared to the initial level were maintained for 12 months in extensor and flexor of the back at patients within SG1 and SG2, as well as up to 6 months in the lateral flexor of the back at patients of SG1. At patients within SG3, the effect of medical rehabilitation completely regressed after 6 months. Higher stabilization parameters after 6 and 12 months in comparison with the initial level were observed only in patients within SG1 and SG2. The effect achieved during rehabilitation was supported for 12 months in the 'stand on one leg' test within SG1, comparing in contrast to SG3, where a deterioration in the average value of the test indicator was noted. CONCLUSION: Long-term use of food supplements containing calcium salts with vitamins D3 and B6can be recommended to maintain the effect of rehabilitation measures at patients with osteoporosis and with a high risk of fractures, more preferably in combination with antiresorptive therapy.

Patients 10 years after total hip arthroplasty have the deficits in functional performance, physical activity, and high fall rate compared to healthy adults.

Background Long-term results in muscle strength, physical activity (PA), and functional improvement after total hip arthroplasty (THA) have not been studied. The purpose of this study was to evaluate the deficits in functional performance, PA, and high fall rate in patient 10 years after THA compared to healthy adults. Methods The subjects were 58 patients who underwent primary THA for unilateral hip osteoarthritis 10 years, and 46 healthy adults. Hip abductor strength, balance function (single-leg stance time), Maximal Walking Speed (MWS), fall rate, and PA (IPAQ short ver.) were evaluated. The unpaired t-test and χ2 test were used to assess differences between the groups. Statistical significance was set at p value <0.05. Results Compared to healthy adults, THA patients had 9.5% less hip abductor muscle strength on the operated side, 42.1% shorter single-leg stance time on the operated side, 14.8% slower MWS, 2.0 times less High-PA group, and 2.8 times higher fall rate (p<0.05). Conclusion This study showed that hip abductor muscle strength, gait speed, balance function, and PA were significantly lower in patients 10 years after THA than in healthy adults. Additionally, the fall rate was significantly higher in patients 10 years post-THA than in healthy adults.

Avaliação isocinética em atletas da seleção brasileira de futebol de 5 / Isokinetic evaluation of Brazilian 5-a-side team / Evaluación isocinética en los atletas de la selección Brasileña de fútbol de 5

INTRODUÇÃO: A força muscular (FM) dos membros inferiores é um dos principais componentes exigidos para as ações específicas durante a prática do futebol de 5 e, quando apresentam níveis insuficientes, desequilíbrios bilaterais elevados ou acentuada diferença na razão agonista/antagonista (RAA) são fatores que contribuem para o desenvolvimento de lesões musculoesqueléticas. OBJETIVO: A proposta deste estudo foi avaliar os níveis de torque máximo, a diferença bilateral na produção de força e a razão convencional das musculaturas flexoras e extensoras do joelho em diferentes velocidades de execução. MÉTODOS: Participaram do estudo 11 atletas deficientes visuais. Os atletas foram submetidos à avaliação antropométrica para determinação da composição corporal e submetidos à avaliação com dinamômetro isocinético para a mensuração dos níveis de desequilíbrio muscular e razão convencional. RESULTADOS: Nos movimentos concêntricos da musculatura flexora foram observadas diferenças significativas no pico de torque (PT) entre os membros dominante (MD) e não dominante (MND) na velocidade de 60°.s-1 e 180°.s-1, no pico de torque normalizado (PTN) a 60°.s-1 e na velocidade de 180°.s-1 para os músculos extensores. Na RAA, observou-se diferença significativa entre MD e MND, e níveis aceitáveis de RAA em ambas as pernas, de acordo com o proposto para o futebol convencional. CONCLUSÃO: Espera-se que os resultados do presente estudo possam contribuir para os processos de prevenção, treinamento e reabilitação de atleta de futebol de 5, como também, servirem como parâmetros para futuros estudos. .

INTRODUCTION: Muscle strength (MS) of the lower limbs is one of the main components required for specific actions during practice of 5-a-side football and when the levels are insufficient, elevated bilateral imbalances or marked difference in agonist/antagonist ratio (AAR) are factors that contribute to the development of musculoskeletal injuries. OBJECTIVE: The purpose of this study was to assess levels of peak torque, bilateral difference in force production and conventional ratio of flexor and extensor musculature of the knee in different speeds. METHODS: The study included 11 visually impaired athletes. The athletes underwent anthropometric measurements to determine body composition and underwent evaluation at the isokinetic dynamometer to measure the levels of muscle imbalance and conventional ratio. RESULTS: In concentric movements of the flexor muscles, significant differences were observed in peak torque (PT) between the dominant limb (DL) and non-dominant limb (NDL) at 60° .s-1 and 180°.s-1, the peak torque standardized (PTS) at 60°.s-1 and 180 °.s-1 to the extensor muscles. In AAR, there was significant difference between DL and NDL, and acceptable levels of AAR in both legs according to the proposed for conventional football. CONCLUSION: It is expected that the results of this study may contribute to the processes of prevention, training and rehabilitation in athletes of 5-a-side football, also, serve as parameters for future studies. .
