Master Thesis Thermal and Physiological Responses of the Human Body During Exercise(Izmir Institute of Technology, 2015) Zora, Süleyman; Başaran, Tahsin; Başaran, Tahsin; Çolakoğlu, Bekir Muzaffer; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyIn this study, the thermal behaviors of the athlete’s bodies were investigated with respect to thermal comfort and exercise intensity experimentally. The relation between Predicted Mean Vote (PMV) which is an thermal comfort index and Ratings of Perceived Exertion (RPE) that measures the exercise intensity and exhaustion level was evaluated statistically. The experiments were carried out with eleven subjects in a conditioned test chamber at School of Physical Education and Sports in Ege University with a bicycle ergometer in 2012 and 2013. The relation between PMV and RPE was analyzed statistically by SPSS and the average correlation coefficient was obtained -0,52. This result mentions that there are a negative moderately correlation. Moreover, the oxygen consumption rate and core body temperature which affect the exercise performance of athletes were divided two groups as high and low and statistically analysis were conducted. Accordingly, while the average correlation coefficient at high oxygen consumption rate group decreases -0,21, the average correlation coefficient at low oxygen consumption rate group increases -0,77. The level of correlation coefficient decreases at the subjects whose oxygen consumption rates are high. Similarly, while the average correlation coefficient at high core body temperature group decreases -0,36, the average correlation coefficient at low core body temperature group increases -0,70. The existed level of correlation coefficients increases at the subjects whose core body temperatures are low.Master Thesis A Mathematical Model of the Human Thermal System(Izmir Institute of Technology, 2005) Yıldırım, Eda Didem; Özerdem, Barış; Özerdem, Mehmet Barış; 03.10. Department of Mechanical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyMathematical model of the human thermal system, which has been greatly developed in recent years, has applications in many areas. It is used to evaluate the environmental conditions in buildings, in car industry, in textile industries, in the aerospace industry, in meteorology, in medicine, and in military applications. In these disciplines, the model can serve for research into human performance, thermal acceptability and temperature sensation, safety limits. Present study investigates the mathematical modeling of the passive part of the human thermal system. The Bio-Heat Equation is derived in order to solve the heat transfer phenomena in the tissue and with environment. It is assumed that the body is exposed to combination of the convection, evaporation and radiation which are taken into account as boundary conditions when solving the Bio-Heat Equation. Finite difference technique is used in order to find out the temperature distribution of human body. The derived equation by numerical method is solved by written software called Bio-Thermal. Bio-Thermal, is used to determine temperature distribution at succeeding time step of the viscera, lung, brain all tissue type of the torso, neck, head, leg, foot, arm, hand, and mean temperature of torso, neck, head, leg, foot, arm, hand. Additionally, for overall body, mean temperature of the bone tissue, muscle tissue, fat tissue, and skin tissue and mean temperature of the total body can be obtained by Bio-Thermal Software. Also, the software is to be capable of demonstrating the sectional view of the various body limbs and full human body. In order to verify the present study, predictions of the present system model are compared with the available experimental data and analytical solution and show good agreement is achieved.
