To determine whether the concentration of fatigue-associated metabolites will be determinant of degree of the fatigue in middle distance swimmers during maximal swimming exercise conditions, we measured heart rate (HR), and lactic acid(LA), ammonia(AM), phosphorus(PHs), uric acid(UA), pH and glucose(Glu) in blood. For this study we recruited elite male middle distance swimmers(n=6) who have been participated about 30 hrs/wk for their routine training programs, and all subjects performed 200M time-trial swimming at similar pace with their ever best records. The resting HR was 54.00±1.84 beat/min, and the HR increased immediately(PostEx-0) after 200M swimming (122.83±1.80/sec) and gradually decreased during 30 min recovery(PostEx-30). The LA was also increased at cessation of exercise, but it was reached a peak value(8.01±0.48mM) after 3-5 min exercise finished. It was not the same pattern shown between HR and plasma LA during recovery period. Blood pH, measured both in plasma and whole, was significantly decreased immediately after swimming, and somewhat(but not completely) recovered with 10 min recovery. Plasma AM was elevated with 200M maximal effort swimming, and significantly decreased(but not completely recovered) after 10min recovery. The pattern of changes in blood pH and plasma AM concentration were similar immediately after swimming and during 10 recovery(p<.05). Unlike plasma AM and blood pH responses, UA was not notably changed following exercise, but it was increased at PostEx-10(9.57±1.14㎎/㎗). Plasma Glu was significantly increased(p<.001) at the cessation of maximal effort of swimming but it was returned to resting values with 10 minutes recovery. The results of this study indicated that physiological profiles could be an efficient marker for monitoring the impact of training and competition performance in 200m elite swimmer.
