31 Plantar flexor series elasticity can be used to dissociate muscle-fascicle and 32 muscle-tendon behaviour and, therefore, afferent feedback during human walking. We 33 used electromyography (EMG) and high speed ultrasonography concomitantly to 34 monitor muscle activity and muscle fascicle behaviour in nineteen healthy volunteers 35 as they walked across a platform. On random trials, the pla...
PURPOSE Improper lifting techniques may increase injury risks and decrease performance. The aim of this study was to compare and contrast biomechanical parameters between sumo and conventional style deadlifts and between high- and low-skilled lifters who participated in the powerlifting event during the 1999 Special Olympics World Games. METHODS Two synchronized video cameras collected 60 Hz ...
Objectives: Lower extremity muscles are critical for maintaining dynamic balance and athletic performance. Fatigue of these may affect balance. It is unclear whether fatigue in a particular muscle group can more than that other groups. This study was conducted to evaluate compare the effects 5 groups on volleyball players. Methods: Fifteen healthy male players separately performed Star Excursio...
Closed kinetic chain exercises are commonly used in strengthening and rehabilitation programs. Altering positions of body segments and supports might affect the way these exercises are performed. The purpose of this study was to compare gluteal, quadriceps, hamstring, and plantar flexor muscle activations during wall-slide (WS) vs. squat-machine (SM) exercise. In addition, the effects of suppor...
[Purpose] This study assessed the relationships between the ankle dorsiflexion range of motion and foot and ankle strength. [Subjects and Methods] Twenty-nine healthy (young adults) volunteers participated in this study. Each participant completed tests for ankle dorsiflexion range of motion, hallux flexor strength, and ankle plantar and dorsiflexor strength. [Results] The results showed (1) a ...
We reported previously that both transcutaneous electrical spinal cord stimulation and direct pressure stimulation of the plantar surfaces of the feet can elicit rhythmic involuntary step-like movements in noninjured subjects with their legs in a gravity-neutral apparatus. The present experiments investigated the convergence of spinal and plantar pressure stimulation and voluntary effort in the...
BACKGROUND Fibromatosis represents a wide group of benign, locally proliferative disorders of fibroblasts. Dupuytren's disease is a benign proliferative disease of palmar aponeurosis which usually affects adults between 40 and 60 years of age. Ledderhose's disease or plantar fibromatosis is plantar equivalent of Dupuyten's disease most often affecting middle-aged and older men, usually bilatera...
