This study proposes a squatting model that describes the relation between center of gravity velocity and lower limb muscle forces contribute to hip knee flexion-extension ankle dorsi-plantar flexion during squatting. Squatting exercises are experimentally monitored using 3D motion analysis system two force plates. Participants perform exercise with their feet shoulder-width apart without weight...

PURPOSE The purpose of this investigation was to determine the effect of stable and unstable conditions on one repetition maximum strength and muscle activity during dynamic squatting using absolute and relative loading. METHODS Ten recreationally weight-trained males participated in this study (age = 24.1 +/- 2.0 y, height = 178.0 +/- 5.6 cm, body mass = 83.7 +/- 13.4 kg, 1RM/body mass = 1.5...

Four-bar linkage mechanisms produced by many designers of knee joints for trans-femoral prostheses can provide knee rotation to permit walking only. In Afro-Asian countries people are accustomed to a squatting posture in their daily activities. A six-bar linkage knee-ankle mechanism trans-femoral prosthesis is described which was developed and fitted to an amputee. The motion patterns of the an...

OBJECTIVES To determine the immediate effects of Kinesio taping directed to the hip and manipulation directed to the lumbopelvic region in individuals with unilateral patellofemoral pain syndrome (PFPS). BACKGROUND PFPS affects up to 25% of the general population. Despite the high prevalence, this condition is not clearly understood, as evidenced by the numerous proposed causes and recommende...

AIM To determine whether kneeling or squatting for prolonged periods is sufficiently causally associated with an increased risk of injury or degenerative disease of the knee joint as to meet the classic criteria to be considered an occupational disease of coal miners for whom these are or have been routine working postures. METHOD Systematic literature searches were made for studies relating ...

Abstract Squatting in Sweden peaked the 1980s. Stockholm and Gothenburg were epicenters, among other smaller towns throughout country. Researchers identified punk music, influences from abroad, anarchist ideas emergence of urban social movements as central to increase squatting during this decade. Only a fragmented picture events has been presented until now, however, often at city level limite...

background the sitting position, rather than squatting, during defecation has been hypothesized to be a risk factor for colorectal cancer (crc). methods we conducted a case-control study to test this hypothesis. a total of 100 crc cases from two hospitals in iran and 100 control subjects, selected from the coronary care unit (ccu) of those same hospitals were selected for this study. we adminis...

This paper demonstrates an optical segment tracking (OST) approach for assessing the in vivo bone loading regimes in humans. The relative movement between retro-reflective marker clusters affixed to the tibia cortex by bone screws was tracked and expressed as tibia loading regimes in terms of segment deformation. Stable in vivo fixation of bone screws was tested by assessing the resonance frequ...

BACKGROUND Activities that require extreme hip movement can dislocate hip implants in the early post operative phase. One such activity is retrieving an object from the floor. The aim of this study was to assess hip movement using four different techniques to accomplish this task. This assessment would identify the techniques least likely to cause a hip dislocation. METHODS An electromagnetic...
