Analysing visual pattern of skin temperature during submaximal and maximal exercises

Abstract

h i g h l i g h t sWe examined skin temperature changes in similar body surface area cohort. A structural relation was observed in skin temperature variations among participants. Temperature pattern of skin was different between maximal and submaximal exercise. Thermal kinetic analysing may be useful tool for monitoring thermoregulations. New method was examined for determining skin temperature by infrared thermography. Aims of this study were to examine our hypotheses assuming that (a) skin temperature patterns would differ between submaximal exercise (SE) and graded maximal exercise test (GXT) and (b) thermal kinetics of T skin occurring in SE and GXT might be similar in a homogenous cohort. Core temperature (T core ) also observed in order to evaluate thermoregulatory responses to SE and GXT. Eleven moderately to well-trained male athletes were volunteered for the study (age: 22.2 ± 3.7 years; body mass: 73.8 ± 6.9 kg; height: 181 ± 6.3 cm; body surface area 1.93 ± 0.1 m 2 ; body fat: 12.6% ± 4.2%; _ VO 2max : 54 ± 9.9 mL min À1 kg a r t i c l e i n f o À1). Under stabilized environmental conditions in climatic chamber, GXT to volitional exhaustion and 20-min SE at 60% of VO 2max were performed on cycle ergometer. Thermal analyses were conducted in 2-min intervals throughout exercise tests. T skin was monitored by a thermal camera, while T core was recorded via an ingestible telemetric temperature sensor. Thermal kinetic analyses showed that T skin gradually decreased till the 7.58 ± 1.03th minutes, and then initiated to increase till the end of SE (Rsqr = 0.97), while T skin gradually decreased throughout the GXT (Rsqr = 0.89). Decrease in the level of T skin during the GXT was significantly below from the SE [F (4, 40) = 2.67, p = 0.07, g p 2 = 0.211]. In the meantime, T core continuously increased throughout the SE and GXT (p < 0.05). Both GXT and SE were terminated at very close final T core values (37.8 ± 0.3°C and 38.0 ± 0.3°C, respectively; p > 0.05). However, total heat energies were calculated as 261.5 kJ/m 2 and 416 kJ/m 2 for GXT and SE, respectively (p < 0.05). Thus, it seems that SE may be more advantageous than GXT in thermoregulation.In conclusion, T core gradually increased throughout maximal and submaximal exercises as expected. T skin curves patterns found to be associated amongst participants at both GXT and SE. Therefore, T skin kinetics may ensure an important data for monitoring thermoregulation in exercise.

Acute Exercise-Associated Skin Surface Temperature Changes after Resistance Training with Different Exercise Intensities

“…For instance, it is important, that the muscles of scullers are equally involved in the performed movement to reach maximum velocity (Chudecka et al, 2015). Furthermore, studies tried to evaluate IRT as a tool for monitoring thermoregulation during and after endurance exercises (Balci, Basaran, & Colakoglu, 2016;Fröhlich et al, 2015;Merla et al, 2010;Priego Quesada et al, 2015;Priego Quesada et al, 2016).…”

Uso Da Termografia Infravermelha Na Identificação De Dor Em Trabalhadores Encaminhados Para Reabilitação

“…Este método tem sido usado com sucesso na prevenção de lesões ortopédicas principalmente na área esportiva. (BALCI et al, 2016;BARBOSA, 2014). A Termografia representa a possibilidade de identificar a dor, a partir de uma resposta fisiológica, evitando a subjetividade do relato de queixa de dor dos funcionários na hora do exame.…”

“…[20][21][22][23], but there are few studies using infrared thermography (IRT). Nevertheless, the use of the IRT technique to evaluate skin temperature in health and sports is constantly growing, which shows the importance of this technique concerning performance in sports [24][25][26][27][28][29][30]. IRT makes detection of the heat pattern and blood flow possible by the use of a special camera to measure the temperature of the skin and is a safe and a noninvasive technique.…”
