ABSTRACT

This chapter examines the influence of water ingestion (WI) during a simulated soccer match on repeated maximum sprint performance. An increase in core temperature has been associated with elevated carbohydrate oxidation and muscle glycogenolysis. Fluid ingestion during exercise may attenuate this temperature rise. In contrast to submaximal exercise performance, dehydration does not appear to reduce the ability of muscle to contract maximally. Blood lactate concentrations was despite more work being done during the sprint phases in the WI-trial. WI-trial, with greater distance covered at speed in comparison with the No Water (NW) ingestion trial. This was associated with the maintenance of pre-match body mass in the WI-trial. Whereas the 2.3" reduction in body mass observed during the NW-trial has previously been associated with impaired athletic performance. Data were analysed by two-way analysis of variance (ANOVA) with repeated measures on factors: time and treatment. A Tukey post hoc test was used to examine any differences.
