the purpose of this study was to investigate the effect of one-month fasting along with yoga training on the body composition of novice female athletes. twenty trained women were randomly assigned to experimental (n=10) and control (n=10) groups. the experimental group participated in yoga training classes for 4 weeks, two 60-min sessions per week; the control group did not participate in any r...

A model sheep, made from metal cylinders and hemispheres, was heated electrically. Heat loss by forced convection in a wind tunnel was analysed in terms of the dependence of the Nusselt number (Nu) on Reynolds number (Re). For a bare trunk Nu = 0.095 Re0.684, but with fleece covering the trunk to a depth of 3.5 cm, Nu = 0.0112 Re0.875 when the mean radiative temperature of the the coat was take...

BACKGROUND Little data is available concerning the heat stress experienced by members of staff who wear bullet-proof vests in a warm or hot environment. For this reason, knowledge is limited and, consequently, preventative advice on how to avoid heat sickness or hyperthermia is required. STUDY DESIGN Skin and body temperatures, fluid loss and the heart rate of 30 persons (15 test persons vers...

It is well documented that exercise-induced asthma is more pronounced when inspired air is cold and dry rather than warm and humid.' 2 The severity of exercise-induced asthma is closely dependent on loss of respiratory heat, needed to warm and humidify inspired air,3 and it has been suggested that airway cooling is the only stimulus triggering postexercise bronchoconstriction.3-7 We present a c...

In the delivery room, wrapping a low-birth-weight neonate (defined as ≤2.499 g) in a polyethylene bag reduces the risk of hypothermia. However, extended use of the bag (e.g., during neonatal surgery) might conceivably increase the risk of thermal stress and thus body overheating. Here, we assessed the efficacy of a polyethylene bag in infants assigned to wrap (W) or nonwrap (NW, control) groups...

Background & Aims of the Study: Heat Stress is a major factor in many industrials and heat stress is one of occupational hazards in the workplace and severely affects the health and productivity, heat stress can decrease efficiency, increase accidents and reduce safety levels. Aim of this study was comparing the heat stress indices of HSI and WBGT and core body temperature in steels ind...
