Abstract: The interactions between the environment and our perception and action are dynamic. Thus, flexible coordination and control of our skeletal muscles are essential when we interact with our environments. In this talk, I will discuss the adaptability of muscle force coordination under the influence of task settings, uncertainty of visual information, and aging constraints. Based on the constraint-to-action framework, we have examined the force adaptability features using both experimental and modeling approaches. I will also share with you the innovative techniques that can provide valuable information regarding the neuromuscular mechanisms of muscle force control in healthy and pathological conditions. Taken together, these approaches allow us to investigate the behavioral and neuromechanical interactions between human and their environments.
