The purpose of this study was to assess the effects of a weekend of swimming competition on various physiological parameters in a group of elite female swimmers. Eight female swimmers (age, 16.6 ± 0.5 years) participated in this study. Resting blood lactate (Bla) and heart rate (HR) were taken at the beginning of each testing session. Testing involved a discontinuous incremental peak VO2 treadmill test during which on-line, measures of VO2 were obtained. HR and Bla measurements were taken at the end of each exercise increment. A 30-s leg Wingate test (WAnT) was used to measure anaerobic power. Paired t-tests were carried out on all data. Resting HR was significantly higher and submaximal and maximal HR were significantly lower comparing pre- and postcompetition (p < .005). Resting Bla and submaximal VO2 were significantly higher postcompetition (p < .005). The results suggest that swimming competition causes a number of the recognized symptoms related to excitatory (acute) overtraining
