Purpose. To investigate changes in blood lactate concentration after the 100 m dash in elite male sprinters. Basic procedures. Nine male sprinters who had their personal best in I to M (Master) sport class. Lactate Scout was used to assess blood lactate concentration. Main findings. Before the warm-up, the average blood lactate concentration was 1,40 ± 0,24, in the 1st min 9,38 ± ± 2,18 mmol*l-1. In the 5th min 10,11 ± 0,99 mmol*l-1 and in the 10th min 9,51 ± 1,23 mmol*l-1. Conclusions. The recovery process pattern is different for male and female sprinters. Blood lactate concentration should not be measured directly after performance or after the 10th-11th min.
