Evaluation Of A Good Physiological Experiment

Introduction: “A Good physiological experiment like a good physical requires that it should present anywhere, at any time, under identical conditions, the same certain and unequivocal phenomena that can be always be confirmed”, Johannes Muller – as an archetype this is the ideal for any experiment and subsequent experiments. If protocols and procedures applications are correctly, they should be repeatable and any results should be consistent. With regard to thermal stress, the following should be noted: Thermal homeostasis is a careful balance of heat production and heat loss with the aim of keeping a constant body temperature. This range as defined by Anderson, Hall and Martin is 36.1°C and 37.8°C, (Anderson et al., 2004) stating that this mechanism is governed primarily by the hypothalamus, which balances this between heat loss and heat gain. Since the factor of heat stress we are looking at is heat gain, from exercise and environmental factors, we need to understand what these are. Both Anderson et al, Mcardle, et al, agree on the factors, Radiation, Conduction, Convection and Evaporation as the four factors regulating heat loss. (McArdle, Katch and Katch, 2006) There are practical considerations with environmental factors such as air temperature and humidity to consider, since these will not be controllable in a field situation, but will be to a degree in a laboratory environment. In the field, testing both temperature and humidity can fluctuate greatly, and
