Neuromuscular and functional responses to concentric and eccentric strength training in older adults

The type of muscle action is important when designing exercise interventions for older individuals and may result in different effects. In this study we performed a systematic review controlled trials comparing the effects concentric eccentric resistance training, on isokinetic dynamometers, lower extremity muscular functional performance adults (CDR42017075316). Six databases (Pubmed, CINAHL, SPORTDiscus, PEDro, Cochrane Central Embase) were searched. Outcomes interest concerned neuromuscular performance. Trials should consider 65 years or participating and/or training at least twice week, during four weeks. Results be compared to control group between contraction types. A qualitative analysis data was done. Quality assessment considered Risk Bias Tool. initial search returned 10376 studies inclusion. Three with ones groups, one training. All focused knee extensor flexor muscles , also ankle dorsiflexors plantarflexors. Training programs included three sessions/week lasting 8-12 Concentric improved strength, power, antagonist coactivation control. isometric, strength self-paced step test, no effect gait speed. They did not structural parameters. findings beneficial power consistent. However, there lack addressing structure functionality.
