Cardiac strain was evaluated in terms of working heart rate (WHR), relative cardiac cost (RCC), net cardiac cost (NCC) and other recovery indices among six younger (mean age 34.2 +/- 2.7 yr) and sixteen older (mean age 48.9 +/- 5.4 yr) drillers working in a manual underground coal mine over two spells of work. The mean WHR was within the range of 117-132 beats / min with corresponding mean rela...

Health and productivity impacts from occupational heat stress have significant ramifications for the large workforce of India. This study profiled occupational heat stress impacts on the health and productivity of workers in select organized and unorganized Indian work sectors. During hotter and cooler seasons, Wet Bulb Globe Temperatures (WBGT) were used to quantify the risk of heat stress, ac...

OBJECTIVE The 2014 FIFA World Cup Brazil included 64 matches in temperate to tropical environmental conditions. We analysed performance data in relation to the environmental conditions to identify potential association. METHODS Wet-bulb globe temperature (WBGT) parameters were obtained at the centre of the field 1 h before the start of play. Environmental stress was estimated (low, moderate a...

BACKGROUND/AIM Exertional heat stress is a common problem in military services. Considering the coagulation abnormalities are of major importance in development of severe heat stroke, we wanted to examine changes in hemostatic parameters in soldiers during exertional heat stress test as well as the effects of a 10-day passive or active acclimatization in a climatic chamber. METHODS A total of...

The welfare of sheep transported by sea is a pertinent issue for Australia’s agriculture industry and subject concern amongst the general public. Evaluating effect transport on livestock requires an accurate system reporting. This study piloted animal monitoring protocol during two voyages from Australia to Middle East. Sheep health behaviour were analysed determine if could detect responses vo...

Because of the differences between indoor and outdoor thermal condition, preparing some outdoor thermal indices is a way to understand and categorize the outdoor thermal sensation. The aim of these indices is not to provide thermal comfort - as it is the aim of indoor indices. Instead, they are provided to analyze outdoor thermal sensation to help architects, landscape architects and urban desi...

Thermal stress is an important factor in many industrial situations, athletic events and military scenarios. It can seriously affect the productivity and the health of the individual and diminish tolerance to other environmental hazards. However, the assessment of the thermal stress and the translation of the stress in terms of physiological and psychological strain is complex. For over a centu...

Background: With the changing climate in the tropical regions, millions of people in indoor and outdoor occupational situations are vulnerable to frequent heat episodes with health implications. Methodology: The study refers to behavioral responses of the men folks (N=999) to hot environment in indoor (iron work N=287, ceramics and pottery N=137, power loom N=143, pulp and paper mill N=31) and ...

Wet bulb globe temperature (WBGT) index is used by many professionals in combination with metabolic rate and clothing adjustments to assess whether a heat stress exposure is sustainable. The progressive heat stress protocol is a systematic method to prescribe a clothing adjustment value (CAV) from human wear trials, and it also provides an estimate of apparent total evaporative resistance (Re,T...
