Task: Answer Verification
Input (English): Question: Does repeated apnea-induced contraction of the spleen in cyclists enhance performance in a subsequent time-trial?
Answer: Our present findings reveal that four apneas by cyclists prior to a 4-km time trial led to splenic contraction, but no change in mean power output, the level of hemoglobin, hematocrit, oxygen saturation of the m. vastus lateralis or oxygen uptake.
Output (English): no
