Leg power is an important characteristic for soccer, and jump tests can measure this capacity. Limited research has analyzed relationships between jumping and soccer-specific field test performance in collegiate male players. Nineteen Division I players completed tests of: leg power (vertical jump (VJ), standing broad jump (SBJ), leftand right-leg triple hop (TH)); linear (30 m sprint; 0–5 m, 5...

The paper presents a study on leg strength as a balance control ability contributor. 9 seniors with the average age of 69.8 years participated in the experimental study. A psychomotor efficiency timer and a standard stabilograph were used in the study. The timer consisted of a computer, a controller and an arm and leg strength measurement station. The subjects performed stepping up movements wi...

What determines organ size has been a long-standing biological question. Lawrence et al. (2008) proposed the steepness hypothesis suggesting that the protocadherin Dachsous/Fat (Ds/Ft) system may provide some measure of dimension to the cells in relation to the gradient. In this paper we extended the model as a means of interpreting experimental results in cricket leg regeneration. We assumed t...

orthopaedic clinic with low back pain and left leg pain for last three months. The low back pain was of gradual onset and was progressive. The pain was aggravated on walking and standing. On clinical examination the patient was fit and well. She had bilateral free straight leg raise. Femoral nerve stretch test on the left leg was positive. She was intact neurologically and the range of movement...

[Purpose] The purpose of this study was to investigate how different standing surfaces alter somatosensory input and how postural control is affected by these changes during the performance of a dual task with a cognitive-motor aspect. [Subjects] The subjects were 20 chronic stroke patients: 18 males, 2 females. [Methods] COP total distance, sway velocity, and the weight load on the paretic leg...

This study investigated how young healthy subjects control their equilibrium in situations of instability specifically elicited by a reduced capacity of force production in the postural muscle system. Ten subjects displaced a bar forward with both hands at maximal velocity toward a target while standing on the dominant leg (UNID), on the nondominant leg (UNIND), or on both legs. In each stance ...

Five experiments examined the organization of spatial memory of an irregular path learned by walking with vision. Two hypotheses were tested: (a) that participants would establish a single global frame of reference to organize the spatial memory of the path; or alternatively (b) that participants would establish path-aligned reference directions at each path leg but not establish a global frame...
