On‐field prediction vs monitoring of aerobic capacity markers using submaximal lactate and heart rate measures

This study aimed to validate the use of a single blood lactate concentration measurement taken following a 5‐minute running bout at 10 km·h −1 ( BLC 10 ) and the speed associated with 90% of maximal heart rate (S 90 ) to predict and monitor fixed blood lactate concentration ( FBLC ) thresholds in athletes. Three complementary studies were undertaken. Study I : A cross‐sectional study examining the associations of BLC 10 and S 90 with running...
