Physiological demands of competitive elite cross-country skiing
Researchers have, for decades, contributed to an increased collective understanding of the physiological demands in cross-country skiing; however, almost all of these studies have used either non-elite subjects and/or performances that emulate cross-country skiing. To establish the physiological demands of cross-country skiing, it is important to relate the investigated physiological variables ...
متن کاملIntegrative Physiological and Biomechanical Aspects in Competitive Cross-country Skiing
METHODS: DP was examined in three studies (A-C), involving roller skiing on a treadmill. In study A (n=6), the subjects performed 10 min of DP at ~74% of their VO2max. Catheters were inserted in a. and v. femoralis, v. subclavia and right atrium to measure a-v O2 difference at systemic level as well as over the arms and legs. Blood flow in arms and legs was measured by constant-infusion thermod...
متن کاملMathematical simulation of energy expenditure and recovery during sprint cross-country skiing
PURPOSE A cross-country sprint competition relies on maximal effort durations of 3-4 minutes. Significant anaerobic energy contribution is expected. Anaerobic energy contribution has been estimated in different sports to date from the accumulated O2 deficit. However, the O2-deficit model can be questioned. We investigate anaerobic energy contribution by applying other methods than the O2 defici...
متن کاملKinematics of sprint cross-country skiing
The purpose of our study was to characterise the diagonal stride locomotion during a new short sprint race in cross-country skiing. Thirty male cross-country skiers were sagittaly filmed on an uphill portion of the 1.2-km classic race of the world cup (2004) using a digital camera. The main body joints, skis and poles were digitised frame by frame. Results indicated higher SV and SR for similar...
متن کاملPerformance diagnostic in cross-country skiing
Purpose. recreational cross-country skiers can benefit from a performance diagnostic when planning a training program. The aim of this study was to establish a simple test protocol to measure endurance capacity and provide training recommendations. Methods. The relationship between endurance performance and cross-country skiing technique was assessed using two tests. First, a lactate threshold ...
