The aim of the study was to assess changes in anterior thigh skin temperature in response to a cold stress test after a strength exercise fatiguing protocol. Ten physically active adults performed a familiarization session and two strength exercise sessions, one with dominant and the other with non-dominant lower limb. Participants performed bouts of 10 concentric and eccentric contractions of leg extensions in an isokinetic device until reaching around 30% of force loss. Infrared thermographic images were taken at baseline conditions and after the fatigue level from both thighs after being cooled using a cryotherapy system. ROIs included vastus medialis, rectus femoris, adductor and vastus lateralis. Skin temperature rewarming was assessed during 180s after the cooling process obtaining the coefficients of the following equation: ΔSkin temperature = β0 + β1 * ln(T), being β0 and β1 the constant and slope coefficients, respectively, T the time elapsed following the cold stress in seconds, and ΔSkin temperature the difference between the skin temperature at T respect and the pre-cooling moment. Lower β0 and higher β1 were found for vastus lateralis and rectus femoris in the intervention lower limb compared with baseline conditions (p < 0.05 and ES > 0.6). Adductor only showed differences in β0 (p = 0.01 and ES = 0.92). The regressions models obtained showed that β0 and β1 had a direct relationship with age and muscle mass, but an inverse relationship with the number of series performed until 30% of fatigue (R2 = 0.8). In conclusion, fatigue strength exercise results in a lower skin temperature and a faster thermal increase after a cold stress test. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.189 2021 ZOOLOGY 13 / 177 = 0.073 2021 Q1 T1 BIOLOGY 43 / 94 = 0.457 2021 Q2 T2 0.644 2021 Agricultural and Biological Sciences (miscellaneous) 2021 Q1 Physiology 2021 Q1 Biochemistry 2021 Q1 4.6 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Priego-Quesada, Jose Ignacio Gimeno Raga, Marc Durán Lozano, Álvaro Gil-Calvo, Marina Universidad de Zaragoza (orcid)0000-0003-4792-1782 1006 245 Universidad de Zaragoza Dpto.
