Objective: To analyze the association between a systematic physical exercise program and functional capacity in institu-tionalized elderly. Methods: The sample included 30 elderly subjects (16 women and 14 men) aged 60 years or older (mean age = 74.43), divided into a control group (n=16) and a training group (n=14), residents in a long-stay institution. A training protocol of 12 weeks, two weekly sessions, was applied, and functional capa-city was assessed before and after the intervention, through chair lift tests (lower limb strength), upper limb strength, timed up and go and handgrip dynamometry. The analysis pre and post-training of intervention and control groups was performed using paired Student t test and the ANOVA test for repeated measures. The level of significance was set at 5%. Results: The main statistical significance were found for the following functional tests: upper limb strength (training 15.6±4.1 x control 10.7±6.6 rep, p

Wistar male rats were divided randomly into four groups: Control (C), Supplemented (S), Training (T) and Training + Supplemented (TS). Groups S and TS received 76mg/kg/day of HMB and the training groups (T and TS) were inserted into concurrent training program 3 times/week for 8 weeks. HMB had positive effects either on body composition of the animals or in type II muscle fibers. The concurrent exercise training was able in reducing the total fat mass as well as in increasing the diameter of muscle fibers. Our findings shows that HMB had an anti-catabolic effect with reference to the parameters of volume, weight and morphology of the soleus muscle, and there was a positive interaction between HMB supplementation and concurrent exercise training.

Pacientes alocados em grupos de treinamento com tubos elásticos (ETG, n=9) e convencional (CRG, n=10) foram avaliados por força isométrica e questionários de qualidade de vida (CRQ) e dispneia (MRC). A força isométrica aumentou em ~25% em ambos os grupos em todos os movimentos (p

Comorbid conditions and unhealthy habits, such as smoking and physical inactivity, are commonly observed in patients with intermittent claudication (IC). However, the impact of these factors on walking impairment in IC patients remains uncertain. Thus, the purpose of this study was to analyze the association between comorbid conditions and non-healthy habits and walking capacity in subjects with IC. Sixty-six men and women with IC were recruited. Subjects underwent a treadmill test in which claudication time (CT) and total walking time (TWT) were obtained. An interview was performed and comorbid conditions and unhealthy habits were obtained. Univariate linear regression was employed for statistical analysis (p < 0.05). The most prevalent comorbid condition was hypertension (86.4%). Among unhealthy habits physical inactivity was the most prevalent (47.0%). Moreover, 90.9% of the subjects had 2 or more comorbid conditions and/or unhealthy habits. Physical inactivity was associated with decreased CT (β = -154 s; p = 0.02; IC95% = -283;-25 s) and TWT (β = -189 s; p = 0.02; IC95% = -384; -29 s). Furthermore, a higher number of factors were associated with lower CT (β = -55 s; p = 0.02; IC95% = -102; -8 s). In conclusion, the results showed that physical inactivity and number of comorbid condition and/or unhealthy habits are associated to walking impairment in subjects with IC Indivíduos com claudicação intermitente (CI) comumente apresentam comorbidades associadas e hábitos não saudáveis, como o tabagismo e a inatividade física. Todavia, o quanto esses fatores contribuem para a intolerância à caminhada desses indivíduos permanece incerto. Assim, o objetivo deste estudo foi analisar a associação das comorbidades e hábitos não saudáveis com a capacidade de caminhada de indivíduos com CI. A amostra foi composta por 66 indivíduos com CI de ambos os gêneros. Todos os indivíduos realizaram teste ergométrico máximo em esteira, sendo registrada o tempo de claudicação (TC) e o tempo total de caminhada (TTC). Os dados referentes às comorbidades e hábitos não saudáveis foram obtidos por meio de entrevista. Para análise estatística foi empregada análise de regressão simples univariada, com p < 0,05. A comorbidade mais prevalente foi a hipertensão arterial (86,4%), ao passo que a inatividade física foi o hábito não saudável mais prevalente (47%). Além disso, 90,9% dos pacientes apresentaram duas ou mais comorbidades e/ou hábitos não saudáveis. A inatividade física foi associada com menor TC (β = -154 s; p = 0,02; IC95% = -283; -25 s) e TTC (β = -189 s; p = 0,02; IC95% = -384; -29 s). Além disso, o maior número de comorbidades e hábitos não saudáveis também foram associados com menor TC (β = -55 s; p = 0,02; IC95% = -102; -8 s). Como conclusão, os resultados deste estudo indicam que a inatividade física e o número de comorbidades e/ou hábitos não saudáveis estão associados com a intolerância à caminhada de indivíduos com CI.
