ABSTRACT
Strength training (ST; high intensity/low volume/long rest) has been used in several populations, including children, young adults, and older adults. However, there is no information about circuit weight training (CWT; low intensity/high volume/short rest) in apparently healthy postmenopausal women. The purpose of the present study was to analyze the effects of high-intensity ST and circuit training on isometric strength (IS), upper limb dynamic strength (ULS) and lower limb dynamic strength (LLS), muscle activation of quadriceps (EMG quad), maximal oxygen uptake (VO2 max), time to exhaustion (TE), and bone mineral density (BMD). Twenty-eight postmenopausal women were divided into 3 groups: 1) ST group (STG, n = 9, 45-80% 1 repetition maximum (1RM), 2-4 sets, 20-6 reps), 2) circuit training group (CTG, n = 10, 45-60% 1RM, 2-3 sets, 20-10 reps), and 3) a control group (CON, n = 9, no exercise).

ABSTRACT
O ultra-som e um exemplo de recurso utilizado pelos fisioterapeutas para obtencao de analgesia em diversos casos de reabilitacao. Entretanto, na literatura nao ha um consenso quanto a real eficacia desse tipo de procdimento no processo reabilitativo. Nao foram encontrados relatos da utilizacao desse recursos no tratamento de pacientes cardiacos pos-operatorios. Objetivo: verificar a eficacia da ultra-sonoterapia na diminuicao dos niveis de dor e do tempo de permanencia pos-operatorio durante a reabilitacao de pacientes que realizaram revascularizacao do miocardio por meio da abordagem de esternotomia mediana. Metodo: a amostra foi composta por oito pacientes divididos em dois grupos? tratamento e placebo, cujo tratamento de reabilitacao consistiu de 5 procedimentos de ultra-sonoterapia em modo pulsado, com frequencia de 3MHz, intensidade de 0,2 W/cm2 regime de pulso a(20 por cento) durante 5 minutos por sessao, duas vezes por dia...
