Endurance training does not change the relative intensity at lactate threshold in elderly

. Sixteen healthy men (64.3 ± 4.1 yrs) underwent an incremental test on cycloer-gometer to determine the LT and the corre-sponding % peak HR at LT intensity. After-wards, they were randomly distributed into two groups (n = 8 each): endurance training (ET) and control (C). The ET exercised 3 days a week for 12 weeks. The training session was divided into warm-up (5 min at 50% of LT;), a main part, and a cool-down (5 min 50% below of LT). The main part had a gradual increased volume through the weeks of 2 min.
