Acceptable reliability of normalisation contractions in electromyography (EMG) is paramount for testing conducted over a number of days or if normal laboratory strength testing equipment is unavailable. This study examined the reliability of maximal voluntary isometric contractions (MVIC) and sub-maximal (60%) isometric contractions for use in neck muscle EMG studies. Surface EMG was recorded b...

To provide data for fatigue life prediction and testing of structural components in off-road bicycles, the objective of the research described herein was to quantify the loads input to an off-road bicycle as a result of surface-induced loads. A fully instrumented test bicycle was equipped with dynamometers at the pedals, handlebars, and hubs to measure all in-plane structural loads acting throu...

Purpose: Assessment of recovery in post-cardiac surgical patients is commonly conducted using lung function, dominant handgrip strength (DHGS), and health-related quality life (HRQoL). The aim this study was to determine the DHGS HRQoL cardiac at six-weeks six-months after hospital discharge. Further, investigated association between these parameters predictive ability for function HRQoL. Metho...

BACKGROUND AND PURPOSE The extent of a patient's impairment can be established by comparing measurements of that patient's performance with normative values obtained from apparently unimpaired individuals. Only a few studies have described normative values for muscle strength measured by hand-held dynamometry. The purpose of this study of older adults, therefore, was to obtain normative values ...

The study of Newtonian mechanics gives students the first chance to question their commonsense assumptions and replace them with a more comprehensive worldview. is cornerstone contemporary science. Furthermore, despite its essential significance, multiple studies demonstrate how challenging it properly comprehend key elements Newton’s equations. Any initiatives increase teaching options are the...

The harmfulness of fine dust generated by automobile brakes to the environment has recently received attention. Therefore, we aimed analyze and regulate brake wear particles in dynamometers. To accurately measure number particle mass, sampling system used needs minimize transportation losses reduce residence time enclosure system. measurement currently can estimate main loss but cannot evaluate...

Appropriate femoral component positioning and sizing is essential for proper kinematic function in total knee arthroplasty (TKA). Anterior or posterior referencing (AR or PR) are two major techniques for setting center of rotation and for balancing the sagittal plane of the arthroplasty. Both techniques have advantages and disadvantages. Minimally invasive surgical (MIS) TKA has added yet anoth...

BACKGROUND Lower limbs antigravity muscles weakness and decreased functional ability have significant role in falling. The aim of this study was to find the effects of aging on muscle strength and functional ability, determining the range of decreasing strength and functional ability and relationship between them in healthy women. METHODS Across-section study was performed on 101 healthy wome...
