Skiing economy and kinematic during a field double poling roller skiing among novice and experienced cross-country skiers

To assess the skiing economy (SE) and kinematics during double poling (DP) roller skiing between two groups of skiers in a field setting. Five experienced and five novice male skiers performed a SE DP test at 16 km∙h −1 on an outdoor athletics track. Gas exchange parameters were measured to determin...

Description
Summary:To assess the skiing economy (SE) and kinematics during double poling (DP) roller skiing between two groups of skiers in a field setting. Five experienced and five novice male skiers performed a SE DP test at 16 km∙h −1 on an outdoor athletics track. Gas exchange parameters were measured to determine SE DP . A two-dimensional video was filmed to measure the kinematics variables. Experienced skiers exhibited a 21% lower oxygen cost than novice skiers (p = 0.016) in DP, indicating a strong association between SE DP , cycle length and cycle rate (p
