“…We should also consider a point in order to understand the divergence on the evolution of the T EC and T C during exercise (i.e., while the T C increase in a uniform way, the T EC decrease with higher variability). On the other hand, the present research differs from Cholewka et al (2016) which studied twelve male cyclists during a incremental test and found a constant increase of T EC as the exercise intensity increased. However, this difference can be explained mainly because of exercise type, since the present study the participants performed continuous exercise fixed to 60% of the V̇O2max speed, while the study of Cholewka et al (2016) carried out an incremental test increasing the intensity every 3 min until maximal effort.…”

Research into obtaining a fast, valid, reliable and non-invasive measure of core temperature is of interest in many disciplinary fields. Occupational and sports medicine research has attempted to determine a non-invasive proxy for core temperature particularly when access to participants is limited and thermal safety is of a concern due to protective encapsulating clothing, hot ambient environments and/or high endogenous heat production during athletic competition. This investigation aimed to determine the validity of inner canthus of the eye temperature (T) as an alternate non-invasive measure of intestinal core temperature (T) during rest, exercise and post-exercise conditions. Twelve physically active males rested for 30min prior to exercise, performed 60min of aerobic exercise at 60% V̇O and passively recovered a further 60min post-exercise. T and T were measured at 5min intervals during each condition. Mean differences between T and T were 0.61°C during pre-exercise, -1.78°C during exercise and -1.00°C during post-exercise. The reliability between the methods was low in the pre-exercise (ICC=0.49 [-0.09 to 0.82]), exercise (ICC=-0.14 [-0.65 to 0.44]) and post-exercise (ICC=-0.25 [-0.70 to 0.35]) conditions. In conclusion, poor agreement was observed between the T values measured through IRT and T measured through a gastrointestinal telemetry pill. Therefore, T is not a valid substitute measurement to gastrointestinal telemetry pill in sports and exercise science settings.

“…Relatively low costs of infrared camera enhance its availability, and nowadays, it seems to be natural consequence of digital technology development. In recent years, applications of thermography as a noninvasive method have become more popular and can be even observed in different areas of sport medicine and science [17][18][19].…”

Allergen sensitization is being diagnosed by commonly available methods in clinical practice-skin prick tests (SPTs) and specific immunoglobulin E test (sIgE). Recently, a new thermographic (TH) method for the assessment of SPT was developed, and it was demonstrated that the TH measurements of forearm temperature distribution during SPT, supported by a mathematical model, offer a new quantification method of allergen-induced skin reactions. The aim of this study is a comprehensive comparison of the TH method with SPT and sIgE techniques. The studies were performed for a group of 51 patients. The SPT and sIgE examinations were done in a routine way. For TH analyses, set of thermograms of both forearms were acquired after prick and analyzed with the use of developed software. All results were converted into categorized scale for comparison. The collected results indicate high correlation coefficients between methods equal to 0.76-0.99. Sensitivity and accuracy of TH assessment in respect of both SPT and sIgE methods is at good level (0.72-0.93). Acceptable level of specificity 0.60-0.88 was also achieved for most allergic responses. Excellent agreement between SPT and sIgE methods was observed which makes the TH assessment competitive. Due to higher precision and sensitivity of digital infrared technology, possibility of making error in diagnosis is significantly reduced. Additional advantage of the TH method relies on an estimation of the skin reactivity which allows highlighting the hypersensitivity patients and automatic correction of the diagnosis.

“…Nevertheless, it follows from Table 5 that temperature correlations with functional parameters such as WR T and VO 2max can be strong and statistical significant (p \ 0.05) or show marked tendency (p B 0.1) for some muscles of legs working intensively during experimental exercise performed on treadmill in Table 4 Mean cutaneous whole body temperature T sk ± SD values for swimmers and crosscountry skiers before and after running exercise Method Swimmers, N = 4 Cross-country skiers, N = 6 Significant differences of T sk before and after treadmill exercise, according to a paired student t test, are shown in bold A preliminary study on infrared thermal imaging of cross-country skiers and swimmers… 707 swimmers, especially. Earlier negative high correlation between power set on bicycle ergometer and average body surface temperature of athletes during progressive test was reported [32]. The strong and statistically significant influence of aerobic fitness (VO 2max ) on the change in surface temperature of the upper limbs immediately after the exercise for athletes who professionally played volleyball was also reported [36].…”

“…There are several possibilities to estimate whole body temperature [23,31,32]. In this paper, we decided to evaluate whole body temperature before and 1-2 min after exercise using two methods, the first according to model used in paper by Cholewka et al [32] and the second based on the model proposed by Choi [31] and partly modified by Tanda [23].…”

This study was focused on the thermal mapping of skin over the selected muscle zones in two groups of elite athletes fully engaged in completely other sports performing about an hour running effort at individual AT intensity. Two groups of elite male athletes, a group of cross-country skiers (CS; N = 6) and a group of elite endurance swimmers (SW; N = 4), were investigated. Thermal images of sportsmen' body at front and from the rear were recorded before and about 1-2 min after exercise test using camera Flir Systems E60. Functional (heart rate, oxygen uptake, workload) as well as biochemical markers (activities of creatine kinase and lactate dehydrogenase, concentration of lactate and haemoglobin) were also assessed. The marked differentiation in skin temperature distribution in cross-country skiers and endurance swimmers subjected to the same endurance exercise on treadmill was observed. There was significant decrease in temperature in upper body temperature in CS group, while SW group revealed a significant increase in temperature of the lower limbs. The calculated total body skin temperature was also influenced by practicing training of elite athletes. Some significant correlations of physiological, biochemical and morphological parameters (% fat) with average temperature after exercise test were found for different muscle zones in swimmers and cross-country skiers. Statistical analysis showed that workload had the most impact on skin temperature changes, especially in swimmers. The results provide additional information on the muscle work in the different sport disciplines and may be helpful in efficiency evaluation of elite athletes.
