Abstract: This study examined the correlational relationships between measures of flexibility and economy (E) during submaximal skate roller skiing in collegiate cross-country skiers. Twelve male competitive skiers (Mean±SD: 21±3 years) completed seven flexibility tests including total body rotation, lateral flexion of spine, shoulder rotation, standing and lying horizontal hip abduction, modified sit-and-reach test, and passive leg raise. During a second lab visit, subjects performed three 10-min roller skiing trials at 65%, 75%, and 85% of maximal heart rate (HR) on an oval indoor track while submaximal oxygen consumption (VO2) and HR were measured via a portable metabolic system. Two methods were used to define roller skiing E: 1) The slopes of the regression lines between VO2 and HR with roller skiing speed for each subject (i.e., VO2 and HR slopes); 2) The predicted VO2 and HR from the individual regression lines when solved for common slow (248 m/min) and fast (309 m/min) roller skiing speeds. Using Pearson product-moment correlations, there were no significant correlational relationships between any measure of flexibility with any measure of E (r = -0.42 to 0.68). These results suggest that flexibility is not a determinant of submaximal skate roller skiing E in collegiate male cross-country skiers.
