简要总结
The aim of this study is to determine whether krill oil supplementation enhances effects of a pragmatic resistance exercise programme on adaptations in muscle strength, mass, function and neuromuscular function in sedentary older adults. Hypothesis - krill oil supplementation will enhance the beneficial effects of resistance exercise on muscle strength, function, mass and neuromuscular function in sedentary older adults.
