Context : Neuromuscular electrical stimulation (NMES) combined with blood flow restriction (BFR) has been shown to improve muscular strength and size better than NMES alone. However, previous studies used varied methodologies not recommended by or BFR research. Objective The present study investigated the acute effects of varying degrees using research-recommended procedures enhance understandi...

This investigation examined the validity of newly developed Adult OMNI Elliptical Ergometer Ratings of Perceived Exertion Scales. 60 men and women performed a graded exercise test on an elliptical ergometer. Oxygen consumption (VO2), heart rate (HR), and ratings of perceived exertion were recorded at each stage from the Borg 15 Category scale and two different OMNI scales. One scale employed an...

Solid-state thermoelastic behavior—a sudden exertion of an expansive or contractive physical force following a temperature change and phase transition in solid-state compound—is rare organic crystals, few are reversible systems, most these limited to dozen so cycles before the crystal degrades they reverse slowly over course many minutes even hours. Comparable thermosalience, wherein changes in...

This paper presents a methodology for the control of robots, in position and force, using electromyographic (EMG) signals recorded from muscles of the shoulder and elbow. A switching model is used for decoding muscular activity to both joint angles and force exerted from the human upper limb to the environment. The proposed method is able to estimate those variables in cases where no force is e...

The goals of this study were to determine the degree to which subjects could voluntarily modulate static endpoint stiffness orientation and to quantify the effects of simultaneously generated voluntary endpoint forces on this ability. Static endpoint stiffness, which characterizes the relationship between externally imposed displacements of the hand and the elastic forces generated in response,...

Human–computer interaction (HCI) is increasingly interested in supporting exertion experiences so more people can benefit from physical activity. So far, most systems have focused on sensing and presenting information to the user via screens support experience. Interestingly, emerging technology also act exerting user's body based sensed information, granting researchers potential develop that ...

INTRODUCTION Mental exertion is a psychophysiological state caused by sustained and prolonged cognitive activity. The understanding of the possible effects of acute mental exertion on physical performance, and their physiological and psychological responses are of great importance for the performance of different occupations, such as military, construction workers, athletes (professional or rec...

Objective. We investigated whether perceived exertion, in comparison to the physiological response to exercise, was associated with self-reported vitality, mental health, and physical function during daily activities, or weight control behaviors. Design. Weight-reduced, formerly overweight women (n = 126, aged 22-46 years), completed health and dietary control questionnaires, and underwent a tr...

background: a cross sectional study was conducted to determine the association between occupational stress risk factors and salivary alpha-amylase activity levels among fresh fruit bunch (ffb) cutters at oil palm plantation.  methods: a total of 109 ffb cutters were selected from two oil palm plantations in pulau carey, selangor at west coast of malaysia in 2015. questionnaires were used to det...
