In this research, the author compared the subjective pace distribution by using 800m running on grand (SPR) with the passive pace distribution by using treadmill running (PPR) by using the intermittent speed increasing method change of the lactic acid concentration in blood at the time. And the purpose was to consider the possible calculation method of LT-2 also in the contestant of an admission level. Consequently, the speed of LT-2 in SPR was lower than PPR, and the lactic acid concentration in blood was high at that time. In order to obtain an index effective in training, when LT-2 of the contestant of an admission level were computed, it was made clear that the numerical value near a race pace with the more nearly actual PPR is acquired.
