Thermal Responses to Exercise in Male Master Track & Field Athletes: Monitoring during Competition

= 0.63°C). Significant changes in Tsk were also found in the left biceps femoris muscle and the right gastrocnemius muscle. In the 50-65 and 70+ age groups, the changes were not statistically significant. Overall, exercise-induced changes in lower-limb skin temperature were evident primarily in the youngest Master athletes, whereas no consistent or statistically significant age-related differences were observed among groups. These findings suggest a relative preservation of thermoregulatory responses with advancing age in trained individuals, however, given the predominantly non-significant inter-group comparisons, age-related interpretations should be considered exploratory.
