“…Considering the effort pulse variable, it was found that heart rate is higher though the running distance is less in the environment with reduced temperature (-11°C). Based on this result, we can conclude that fatigue threshold falls in cold weather [16,17].…”

This study was conducted to determine the changes in ambient temperatures that may occur in some performance values of female soccer players. The research group consisted of 15 female amateur soccer players. (Age: 19,15, Height: 164,12, Body Weight: 54,48, BKI: 19,65). Study performance values of 30m sprint speed, 20m shuttle run and İllinois test were measured at three different ambient temperatures (-5,5°C, 10,5°C, 30°C ). In the analysis of the data; "SPSS 23" package program is used. The distributions of the variables according to the groups were examined and the distributions were parametric by evaluating the normality of the distributions. Repeated Measure ANOVA was used to compare the data obtained at 3 different ambient temperatures from the variables exhibiting parametric properties. In addition, Bofferoni test were performed to determine which groups the difference was in when there were significant differences when the multiple variables were examined. The level of significance in the analyzes was taken as 0.01 and 0.05. As the temperature values increased, all the measured parameters showed significant changes compared to the measurements in the cold environment and there was a significant difference in the performance values (p<0.05).As a result; as the temperature values increased, all the measured parameters were significantly different from the measurements in the cold environment. It is seen that high efficiency is obtained in all sporting activities in hot environment and as a result the performance of the athletes is increased according to environment temperature (-5,5°C to 30°C).

“…The high-temperature working environment is defined as one in which the dry bulb temperature is over 35 o C with the combined effect of radiation, high humidity and other thermal factors [14], and that would cause significant heat storage in the human body [15,16]. The initial studies have mainly concentrated on the physiological responses of the human body to heat stimuli and health protection [17][18][19][20], and the indices to evaluate heat stress (e.g.…”

The parameter of human body metabolic rates has been popularly used for the prediction of human heat stress in hot environments. However, most modules use the fixed and estimated metabolic heat production. The aim of this study is to develop the prediction of personal heat stress in dynamic working environments. Based on the framework of the predicted heat stress (PHS) model in ISO 7933, a heart-rate based PHSHR model has been developed using the time-based heart rate index, which is suitable for prediction in situations where metabolic rates are dynamic and there are inter-individual variations. The infinitesimal time unit Δti, has been introduced into the new PHSHR model and all the terms used in the PHS model related to metabolic rates are thus redefined as the function of real-time heart rates. The PHSHR has been validated under 8 experimental combined temperature-humidity conditions in a well-controlled climate chamber. The feature of the PHSHR model is being able to calculate dynamic changes in body metabolism with exposure time. It will be useful to the identification of potential risks of individual workers so to establish an occupational working environment health and safety protection mechanism by means of simultaneous monitoring of workers' heart rates at the personal levels, using advanced sensor technology.
