Caffeine increases performance in cross-country double-poling time trial exercise.
PURPOSE Caffeine (CAF) improves performance in both short- and long-duration running and cycling where performance relies on power output and endurance capacity of leg muscles. No studies have so far tested the effects of CAF while using the double-poling (DP) technique in cross-country skiing. When using the DP technique, arm muscles provide the speed-generating force and therefore play an imp...
متن کاملBiomechanical analysis of double poling in elite cross-country skiers.
PURPOSE To further the understanding of double poling (DP) through biomechanical analysis of upper and lower body movements during DP in cross-country (XC) skiing at racing speed. METHODS Eleven elite XC skiers performed DP at 85% of their maximal DP velocity (V85%) during roller skiing at 1 degrees inclination on a treadmill. Pole and plantar ground reaction forces, joint angles (elbow, hip,...

متن کاملCaffeine improves performance in double poling during acute exposure to 2,000-m altitude.
There is limited research on the physiological effects of caffeine (CAF) ingestion on exercise performance during acute hypoxia. The aim of the present study was therefore to test the effect of placebo (PLA) and CAF (4.5 mg/kg) on double poling (DP) performance during acute hypoxia. Thirteen male subelite cross-country skiers (V̇o2max 72.6 ± 5.68 ml·kg(-1)·min(-1)) were included. Performance was...

24 There is limited research on the physiological effects of caffeine (CAF) ingestion on exercise 25 performance during acute hypoxia. The aim of the present study was therefore to test the 26 effect of placebo (PLA) and CAF (4.5 mg·kg) on double poling (DP) performance during 27 acute hypoxia. Methods: Thirteen male sub-elite cross-country skiers ( O2max72.6 ± 5.68 28 mL·kg·min) were included....
