Measurements of the sub-maximal speed (16 km·h−1) test for experienced (n = 5) and novice (n = 5) skiers during double poling. Hip (a), knee (b), and elbow (c) angles at pole plant (IN-PP), angle minima value during the poling phase (MIN-PP), angles at the end of the poling phase (OFF-PP), and hip and knee angle maxima value during the recovery phase (MAX-RP). (a–c) Y-axes indicate mean angles (°) and X-axes represent time (s). (d) Mean body position of the two groups of skiers at the pole plant moment (bold lines denote the experienced skiers, and dotted lines denote the novice skiers).
