| Abstract: | To assess effects of a short-term strength training (ST) program on muscle quality (MQ) and functional capacity, 36 sedentary elderly women (age?=?66.0?±?8 year, height?=?159.1?±?9.2 cm, body mass?=?68.3?±?12.1 kg, body fat?=?37.0?±?4.2 %) were randomly divided into an experimental group (EG; n?=?19) or a control group (CG; n?=?17). The EG performed two to three sets of 12–15 repeats of leg press, knee extension, and knee flexion exercises, 2 days/week for 6 weeks. Before and after training, lower body one repetition maximum (1RM), functional performance tests, quadriceps femoris muscle thickness (MT), and muscle quality (MQ) (1RM and quadriceps MT quotient) were assessed. After training, only the EG showed significant improvements in 1RM (p?p?p?p?≤?0.05), and MQ (p?r?=?0.62, p?r?=??0.71, p? |
