OBJECTIVE To investigate the acute effects of isolated eccentric and concentric calf muscle exercise on Achilles tendon sagittal thickness. DESIGN Within-subject, counterbalanced, mixed design. SETTING Institutional. PARTICIPANTS 11 healthy, recreationally active male adults. INTERVENTIONS Participants performed an exercise protocol, which involved isolated eccentric loading of the Achi...

PURPOSE The purpose of the current investigation was to determine the relationship between relative net vertical impulse (net vertical impulse (VI)) and jump height in the jump squat (JS) going to different squat depths and utilizing various loads. METHODS Ten males with two years of jumping experience participated in this investigation (Age: 21.8 ± 1.9 y; Height: 176.9 ± 5.2 cm; Body Mass: 7...

For short duration impulse loadings, elastic granular chains are known to support solitary waves, while elastoplastic chains have recently been shown to exhibit two force decay regimes [ Pal, Awasthi and Geubelle Granular Matter 15 747 (2013)]. In this work, the dynamics of monodisperse elastic and elastoplastic granular chains under a wide range of loading conditions is studied, and two distin...

The results of the assessment dynamic behavior three-layer cylindrical shells circular and elliptical cross-sections under internal impulse loading are given. finite-element method was used to calculate indicators stress-strain state (SSS) such structures by NASTRAN software complex. values normal deflections stresses three forms intersection determined. A comparative analysis these with uneven...

BACKGROUND An increase in the knee adduction moment is one of the risk factors of medial knee osteoarthritis. This study examined the relationship between knee adduction moment and self-reported pain and disability. We also investigated the influence of pain on the relationships between knee adduction moment and gait performance and disability. METHODS Thirty-eight Japanese women with medial ...

After unilateral total knee arthroplasty (TKA), osteoarthritis (OA) in the non-operated knee often progresses. The altered gait mechanics exhibited by patients after TKA increase the loading on the non-operated knee and predispose it to disease progression. Therefore, our objective was to examine the potentially detrimental changes in frontal plane kinetics and kinematics during walking in pati...

impulse buying is a significant aspect of consumer behavior and a critical concept in the marketplace. dramatic increases in consumption and possibility of credit buying all over the world has provided appropriate situations for impulse buying, however there is little information about impulse buying in eastern and in transition societies and economies. the purpose of this study is to develop a...

Background: Forward head posture is one of the most prevalent abnormal postures in patients with neck disorders. The aim of this study was to evaluate the effects of forward head posture on gait ground reaction force characteristics in children. Methods: Twelve children with forward head posture (age: 11.8±1.3 years) and sixteen healthy control children (...

The prosthetic sockets of 14 independent persons with unilateral trans-tibial (BK) amputation were mounted on an adjustable alignment pylon. Vertical ground reaction forces were recorded in neutral prosthetic alignment and in 10 degrees of prosthetic socket varus, valgus, flexion, and extension. Stance phase time, peak vertical ground reaction force, and impulse were all found to be increased o...
