. Methods.— Twenty five trail runners (mean age 31.2 ±5.1 years) completed a standard graded exercise test on the treadmill for determination of maximal oxygen uptake (VO 2 max 59.5±5.2 ml·kg -1. min -1 ) and LT. Values and velocities for aerobic LT (AET), individual anaerobic LT (IAT according to Dickhuth

, 2003 ). This decline in VO 2 peak may be related to both central (maximal heart rate and stroke volume) and peripheral (arteriovenous oxygen difference) factors. One of the most common findings in endurance athletes is an age-related reduction in maximal heart rate of ∼3% to 5% per decade ( Hawkins
