ABSTRACT

The data from the current investigation demonstrate that active (AH) and passive prewarming (PH) strategies increase the short-term thermoregulatory strain during soccerspecific intermittent exercise in ambient temperatures of 19°C, compared with preexercise rest. Current findings also indicate that the effects of pre-warming on the physiological response to soccer-specific intermittent exercise are independent of the prewarming strategy utilised. The present observations suggest that the physiological changes arising as a result of pre-warming strategies are unlikely to have detrimental

effects on the performance of a 90-min soccer-specific simulation under the current environmental temperatures.
