“…To adequately interpret thermographic data, a set of internal factors such as age (Falk and Dotan, 2011;Charkovduran, 2010;Niu et al, 2001), gender (Falk and Dotan, 2011), level of fitness (Magalhaes et al 2010;Merla et al, 2005), and external factors including the degree of hydration (Charkovduran, 2010), clothing (Gonzales et al, 2011) or environmental conditions (Moris et al, 2005) should be considered. Furthermore, an appropriate protocol for infrared imaging is crucial to obtain quality thermographic images (Ammer and Ring, 2008).…”

Thermal body patterns for healthy Brazilian adults (male and female), Journal of Thermal Biology, http://dx.doi.org/10. 1016/j.jtherbio.2014.02.020 This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting galley proof before it is published in its final citable form.

A B S T R A C TThe aim of this study was to establish the skin temperature (T sk ) thermal profile for the Brazilian population and to compare the differences between female and male Brazilian adults. A total of 117 female and 103 male were examined with a thermographic camera. The T sk of 24 body regions of interest (ROI) were recorded and analyzed. Male T sk results were compared to female and 10 ROI were evaluated with respect to the opposite side of the body (right vs. left) to identify the existence of significant contralateral T sk differences (ΔT sk ). When compared right to left, the largest contralateral ΔT sk was 0.3 °C. The female vs. male analysis yielded significant differences (p <0.05) in 13 of the 24 ROI. Thigh regions, both ventral and dorsal, had the highest ΔT sk by sex (≈ 1.0 °C). T sk percentile below P 5 or P 10 and over P 9o or P 95 may be used to characterize hypothermia and hyperthermia states, respectively. Thermal patterns and T sk tables 2 were established for Brazilian adult men and women for each ROI. There is a low T sk variation between sides of the body and gender differences were only significant for some ROIs. Keywords: Infrared thermographySkin temperature Thermal symmetry Brazilian profile HighlightsEstablishing a standard thermographic profile is crucial for an appropriate interpretation.Standardization of the protocols leads to obtain comparable results.Gender seems to be a determining factor for the skin temperature of the thigh, calf and dorsal arm.We suggest the value of 0.5 °C as a normal limit for contralateral ΔT sk.

“…17 The thermal changes that occurred in deep areas of the body are transferred to the superficial tissue by the blood circulation. 8,27 Few studies have examined the alterations of thermographic patterns after exercise 2,17,18,[26][27][28] and none of them assessed the possible thermographic profile changes associated to localized exercise in elderly subjects. It is well known that aging is related to muscle mass loss and metabolism reduction, which limits heat production and thermoregulatory adjustments.…”

Exercise-Associated Thermographic Changes in Young and Elderly Subjects

This study aimed at evaluating the thermographic changes associated with localized exercise in young and elderly subjects. An exercise protocol using 1 kg load was applied during 3 min to the knee flexors of 14 elderly (67 +/- 5 years) and 15 young (23 +/- 2 years) healthy subjects. The posterior thigh's skin temperature of the exercised limb and contralateral limb were measured by infrared thermography on pre-exercise, immediately post-exercise, and during the 10-min period post-exercise. Difference (p < 0.01) between elderly and young subjects was observed on pre-exercise temperature. Although differences were not observed between pre-exercise and immediately post-exercise temperature in the exercised limb, thermographic profile displayed heat concentration in exercised areas for both groups. Temperature reduction was only observed for the young group on the 10-min post-exercise (p < 0.05) in the exercised limb (30.7 +/- 1.7 to 30.3 +/- 1.5 degrees C). In contrast, there was a temperature reduction post-exercise (p < 0.01) in the contralateral limb for both groups. These results present new evidences that elderly and young subjects display similar capacity of heat production; however, the elderly subjects presented a lower resting temperature and slower heat dissipation. This work contributes to improve the understanding about temperature changes in elderly subjects and may present implications to the sports and rehabilitation programs.

“…The thermal pattern can also be influenced by the fitness level; trained subjects present better cooling capacity during exercise and faster recovery [51] thanks to an improved thermoregulation system and greater vascularization of the musculature compared with non-trained [24,46,61]. The muscles of our highly skilled sample may present earlier and more responsive skin blood flow responses, consequently the onset of vasodilation would occur at lower internal temperatures [62] and the T sk would start growing sooner than in a less fit sample.…”

“…Most the studies in which the subjects were exposed to constant and prolonged exercise resulted in an increased T sk [17,[36][37][38][39][40][41][42][43][44][45][46]. In contrast, graded, intermittent or maximal exercises normally performed for brief period, resulted in decreased T sk [18,[47][48][49][50][51][52][53][54][55]. Based on this trend our short test should produce a reduction of the T sk once it finalized.…”

h i g h l i g h t sT sk response of wheelchair athletes before and after a propulsion test is presented. The relation between SP and T sk before and after the propulsion test is obtained. Subjects showed lower resting T sk and slower heat dissipation than able-bodied. There were significant negative correlations between the T sk and SP. There were no correlations between the kinematic variables and the shoulder pain. a b s t r a c t Introduction: Wheelchair Users (WCUs) depend on their upper extremities for their daily living. Therefore, it is not unusual to find that shoulder pain (SP) is a problem for WCUs and reduces their participation in sport and leisure activities. Objectives: The aims of this study were 1 -to analyse skin temperature measured by infrared thermography (IRT) before (pre-test), one minute after (post-test) and 10 min after (post-10) the kinematic wheelchair propulsion test (T-CIDIF) of athletic wheelchair users; 2 -to evaluate the relationship between shoulder pain (SP) and Skin Temperature Asymmetry (DT sk ) before and after (pre-test, posttest, post-10) the T-CIDIF, and to relate the SP with the kinematic variables of the T-CIDIF. Participants & interventions/procedure: A volunteer sample of 12 wheelchair athletes completed an exercise test (T-CIDIF) in their own wheelchair. It consisted in a 30-s maximum test performed on two rollers. Two linear transducers connected to the rollers registered the number of propulsions, maximum and mean velocity and power of each arm. SP was assessed with the Wheelchair Users Shoulder Pain Index (WUSPI). Skin temperature (T sk ) of the anterior and posterior upper body was measured before and after the T-CIDIF by using an infrared camera. A total of 26 ROIs were evaluated with respect to the opposite side of the body to identify significant (DT sk ). Results/main outcome measure(s): Significant differences were observed between the T sk of the post-10 and pre-test in 12 ROIs, and between the post-10 and the post-test in most of the ROIs. These differences are attenuated when the DT sk is compared before and after exercise. T sk tends to initially decrease immediately after the test and then significantly increase after 10 min of completing the T-CIDIF. The DT sk vs SP analysis yielded significant inverse relationships (from r = À0.58 to r = À0.71, p < 0.05) in 5 of the 26 ROI. No significant correlations between propulsion variables and SP questionnaire were found. All T-CIDIF variables were significantly correlated with the temperature asymmetries in multiple ROIs (from r = À0.86 to r = À0.58, from p < 0.05 to p < 0.001). Conclusions: These results present indications that high performance wheelchair athletes exhibit similar capacity of heat production than able-bodied. The thermographic data inversely correlates with the SP and the kinematic variables, but the last is not related to SP. This work contributes to improve the understanding about temperature changes in wheelchair athletes during exercise, and could be used to assess the efficacy of various ...
