Identifying physiological determinants of 800 m running performance using post-exercise blood lactate kinetics.

ABSTRACT:

Purpose

The aims of the present study were to investigate blood lactate kinetics following high intensity exercise and identify the physiological determinants of 800 m running performance.

Methods

Fourteen competitive 800 m runners performed two running tests. First, participants performed a multistage graded exercise test to determine physiological indicators related to endurance performance. Second, participants performed four to six 30-s high intensity running bouts to determine post-exercise blood lactate kinetics. Using a biexponential time function, lactate exchange ability (γ₁), lactate removal ability (γ₂), and the quantity of lactate accumulated (QLaA) were calculated from individual blood lactate recovery data.
