Assessment of Heart Rate Variability Thresholds from Incremental Treadmill Tests in Five Cross-Country Skiing Techniques
The assessment of heart rate variability (HRV) thresholds (HRVTs) as an alternative of Ventilatory thresholds (VTs) is a relatively new approach with increasing popularity which has not been conducted in cross-country (XC) skiing yet. The main purpose of the present study was to assess HRVTs in the five main XC skiing-related techniques, double poling (DP), diagonal striding (DS), Nordic walking (NW), V1 skating (V1), and V2 skating (V2).Ten competitive skiers completed these incremental treadmill tests until exhaustion with a minimum of one to two recovery days in between each test. Ventilatory gases, HRV and poling frequencies were measured. The first HRV threshold (HRVT1) was assessed us…
Assessment of aerobic and anaerobic thresholds in five different technique specific incremental treadmill tests in cross country skiers
The use of incremental tests to exhaustion is widely accepted in the field of exercise physiology in the assessment of athletes. These tests which can measure a number of physiological parameters can help coaches and athletes optimize training. Blood lactate concentrations (bLa) corresponding to heart rate (HR) provides insight on the athlete’s aerobic threshold (AerT) and anaerobic threshold (AnT). Cross country skiing is a sport where the selection of technique may influence the HR at which AerT and AnT occurs, eliciting higher bLa corresponding to lower HR depending on technique. Because of this, laboratory testing is crucial to provide coaches and athletes with the necessary information…
