Abstract
Cardiovascular fitness is an important health marker but reference values for the performance at lactate thresholds are lacking. This study aimed to provide reference standards for the performance on the cycle ergometer at fixed and individual lactate threshold 2 concepts throughout the lifespan. Data from two nationwide studies in Germany (KiGGS wave 2 and DEGS1 study) were pooled to a final sample of 2389 female and 2801 male participants aged 14-64. The data includes the results of an incremental bicycle ergometer test for the parameters absolute (W) and relative (W/kg) power at a fixed (3 mmol/l, LT2fix) and at an individual lactate threshold 2 (base lactate + 1 mmol/l, LT2ind). Generalized additive models for location, scale, and shape (GAMLSS) were used to calculate the reference values. The LT2ind was reached at lower power than the LT2fix. 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.
期刊介绍:
The Journal of Sports Sciences has an international reputation for publishing articles of a high standard and is both Medline and Clarivate Analytics-listed. It publishes research on various aspects of the sports and exercise sciences, including anatomy, biochemistry, biomechanics, performance analysis, physiology, psychology, sports medicine and health, as well as coaching and talent identification, kinanthropometry and other interdisciplinary perspectives.
The emphasis of the Journal is on the human sciences, broadly defined and applied to sport and exercise. Besides experimental work in human responses to exercise, the subjects covered will include human responses to technologies such as the design of sports equipment and playing facilities, research in training, selection, performance prediction or modification, and stress reduction or manifestation. Manuscripts considered for publication include those dealing with original investigations of exercise, validation of technological innovations in sport or comprehensive reviews of topics relevant to the scientific study of sport.
