Lactate performance diagnostics are recommended for anyone who plays sport, whether they are a professional or amateur athlete. After all, individual training is the basis for optimal performance! During this process, blood is painlessly taken from the earlobe during a defined bicycle ergometric load, and the lactate value (salt of lactic acid) is determined. Based on the values determined, the athlete learns his or her optimal pulse training ranges. This helps to optimise performance and avoid overloading and its consequences.
