Interaction of leg stiffness and surfaces stiffness during human hopping.
When mammals run, the overall musculoskeletal system behaves as a single linear "leg spring". We used force platform and kinematic measurements to determine whether leg spring stiffness (k(leg)) is adjusted to accommodate changes in surface stiffness (ksurf) when humans hoop in place, a good experimental model for examining adjustments to k(leg) in bouncing gaits. We found that k(leg) was great...

متن کاملEffect of hopping frequency on bilateral differences in leg stiffness.
Understanding the degree of leg stiffness during human movement would provide important information that may be used for injury prevention. In the current study, we investigated bilateral differences in leg stiffness during one-legged hopping. Ten male participants performed one-legged hopping in place, matching metronome beats at 1.5, 2.2, and 3.0 Hz. Based on a spring-mass model, we calculate...
متن کاملLeg stiffness adjustment during hopping at different intensities and frequencies.
Understanding leg and joint stiffness adjustment during maximum hopping may provide important information for developing more effective training methods. It has been reported that ankle stiffness has major influence on stable spring-mass dynamics during submaximal hopping, and that knee stiffness is a major determinant for hopping performance during maximal hopping task. Furthermore, there are ...
متن کاملOptimizing Legged Locomotion Using Tunable Leg Stiffness
Running efficiently and successfully over unstructured terrain is an important and necessary characteristic for modern legged robots. Research suggests that a necessary step toward achieving this goal is to design legged robots with variable leg stiffness capabilities which can be controlled by the robot autonomously. The specific problem addressed in this research is to develop a wireless (inf...
