Core temperature is known to increase during exercise and the magnitude of this increase is determined by the relative stress of the exercise, the environmental conditions and hydration status (Saltin and CosUII 1988). Due to technical limitations associated with the measurement esophageal and rectal] temperatures in field based contact sports (O'Brien et al. 1998). Few studies have reported core temperature either during or immediately following professional soccer match performance. The aim of this study was therefore to identify a practical method of core temperature assessment in response to match play.

Seven healthy 1st team male soccer players from a professional English Division One team agreed to participate in this study. Four hours prior to a competitive match all players ingested a telemetric temperature pill (Tpill)(CorTempTM. Human Technologies Inc). Blood samples were taken pre and post match for the assessment of Het. Hb, blood lactate concentrations and plasma volume. Four players agreed to core temperature assessment at half-time but the remaining three players were unavailable while receiving tactical instruction from the coaching staff. Statistical analysis was performed using student paired tests.

Tpill increased significantly pre to post match in all C) (P°O.6 ±C to 38.6'0.5 ±(n=7) players (36.9 <0.01) and showed a trend for increased Tpill from half-time to full-time (n=4) (P<0.1). Body mass (-1.9 %) and plasma volume (11.6%) both decreased significantly pre to post match (P<O.Ol). Blood lactate concentrations increased Significantly from resting to half-time(P<O.01 but were not different from half-time to full-time.

In conclusion, the telemetry thermometer pill provided a novel and acceptable alternative assessment of core temperature during match play in professional soccer players. As individual thermoregulatory responses of players are difficult to predict, players need to be individually assessed in order to be able to understand their thermoregulatory responses to the requirements of professional soccer. Repeated individual assessments can then be made to establish an appropriate strategy for avoiding or diminishing dehydration and the associated negative effects on performance.
