During human movement, the leg can be represented as a mechanical spring, with its stiffness potentially contributing to sports performance and injury prevention. Although many individuals perform athletic activities with joint stabilizers, little is known about the effects of prophylactic lower extremity braces on leg stiffness. The objective of this study was to investigate the effect of ankl...

Transcranial magnetic stimulation (TMS) was applied to motor areas in the left language-dominant hemisphere while right-handed human subjects made lexical decisions on words related to actions. Response times to words referring to leg actions (e.g. kick) were compared with those to words referring to movements involving the arms and hands (e.g. pick). TMS of hand and leg areas influenced the pr...

Background and Aims One of the most important structural abnormalities in foot is decrease height medial longitudinal arch when bearing body weight, which causes deformity ankle its pronation. The present study aims to compare static balance, posture, selected plantar parameters adolescent girls with pronation healthy peers. Methods This quasi-experimental causal-comparative study.

Rugby union is a dynamic running game requiring players to regularly perform change of direction maneuvers to avoid player opposition. The change of direction/cutting task is characterized by rapid deceleration onto the plant leg (PL) then reacceleration by the push-off leg (POL) into the new direction. Identification of the kinematic characteristics of cutting tasks and their relationship to p...

This study investigates the influence of specific soccer training with the non-dominant leg on mental rotation performance of 20 adolescent soccer players between 10 and 11 years of age. While the experimental group performed soccer specific tasks only with the non-dominant foot once a week for 10 weeks, the control group absolved the same exercises with the dominant foot for the same period of...

Muscle power in the lower extremities and body sway were measured in 57 healthy young women volunteers in their 20's. Body sway was measured with a stabilimeter for 30 sec during two-leg standing, and for 10 sec during one-leg standing with the eyes open or closed, alternating between right and left legs (5 times each). The measured parameters of body sway were locus length per time unit, locus...

Unlike most other arthropods, spiders have no extensor muscles in major leg joints. Therefore, hydraulic pressure generated in the prosoma provides leg extension. For decades, this mechanism was held responsible for the generation of the majority of the ground reaction forces, particularly in the hind legs. During propulsion, the front leg pairs must shorten whereas the hind legs have to be ext...

Beerse, Matthew, "Effects of frequency on single leg hopping in typically developing preadolescents. Abstract Hopping is considered a mass-spring model movement in which the leg supports the center of mass. There is a preferred hopping frequency and hopping outside of that frequency is more difficult and requires more energy. Leg stiffness has been shown to be an important factor when hopping a...
