This article examines leisure time physical activity (LTPA) for middle-class women as relational, intricately linked with societal understandings of personal responsibility to work, to family and to health and entangled with the emotion management of 'successful' middle-class womanhood. We focus on middle-class Danish women who engage in routinised participation in LTPA. We illuminate through our qualitative study how emotional reflexivity involves dispersed practices that are entangled with this lifelong physical activity and how these entangled, mutually evolving practices enable women to dutifully enact 'successful' womanhood, in line with contemporary ideals.

This study assessed associations between hydration status (copeptin, urinary osmolality, urine volume) and habitual fluid intake with cortisol dynamics.

Methods: The day before (DB) a 6-h laboratory visit, 29 male participants (age, 23±4y; BMI, 25.

Background: Although varieties in chewing patterns are essential for the transformation of food in mouth and thereby its sensorial perception, there are few reports that show the effect of chewing frequency on food oral processing and its properties.

Objective: The current study tested whether consciously controlled chewing frequency influences the oral processing of habitually consumed foods and their sensory analysis.

Method: Chewing behaviour was analysed during the mastication of mushed potato samples by 20 participants in two separate test sessions, in which they were instructed to chew the sample in their habitual manner (free chewing test) or follow a preprogrammed video animation displayed on a screen, wich guided them to maintain a constant chewing frequency (F-const chewing test).

Background: There is much concern that opioids administered as intravenous (iv) bolus for pain relief may inadvertently increase their risk for abuse. However, there is insufficient data to support this. The authors compared the abuse liability potential, analgesic efficacy, and adverse effect profile of fast (iv push) versus slow (iv piggyback) administration of iv hydromorphone among hospitalized patients requiring iv opioids for pain.
