The aim of a 12-week randomized double-blind placebo-controlled study was to assess the effect of daily supplementation with a natural extract of L. (4 × 500 mg capsules/day; total 2 g per day) combined with a moderate-intensity training program (1 h session/3 times a week) on skeletal muscle fitness in adults over 50 years of age. Muscle strength assessed by isokinetic and isometric dynamometry improved significantly in the experimental ( = 23) and the placebo ( = 22) groups, but the magnitude of improvement was higher in the experimental group, with between-group differences in almost all variables, including isokinetic at 60° s in knee extension, peak torque ( < 0.007); total work per repetition maximum ( < 0.009); isokinetic at 180°s in knee extension, peak torque ( < 0.002); total work ( < 0.007); total work per repetition maximum ( < 0.005); average power ( < 0.027); isometric in knee extension, peak torque ( < 0.005); and average peak torque ( < 0.002). Similar findings were observed for muscle quality. Changes in quality of life (SF-36) were not found, except for improvements in the role physical ( < 0.023) and role emotional ( < 0.001) domains, likely as a result of the physical training sessions. A nutritional survey did not revealed changes in dietary habits. No adverse events were recorded. In subjects over 50 years of age, moderate-intensity strength training combined with daily supplementation for 12 weeks with a natural extract of L. improved muscle-related variables and muscle quality. Maintaining muscle health is a key component of healthy aging.
