Reference standards for power at the lactate threshold 2 for cycle ergometry throughout the lifespan in Germany

. Throughout the lifespan, relative power had its peak at 14 years, declined until age 20 and then declined further but slower until the maximum age of 64 years. Absolute power remained fairly stable until age 45 after which it slowly declined until maximum age. The presented reference values can be used for estimating cardiorespiratory fitness among adolescents and adults in Germany.
