The study found significant correlations between mechanical capacities determined on and off the ice with skating performance, especially in the 40-m skating split time. Performance variables between jumping, running, and skating tasks showed strong associations with P-maxrel. Mechanical variables inferred from force-velocity tests showed moderate to very large correlations between off-ice and on-ice measurements.
This study aimed to investigate the correlations between players' mechanical capacities determined during off- and on-ice tests. Whole body force-velocity relationships were assessed in elite female ice hockey players (n = 17) during jumping [squat jump (SJ)], running (5 and 30 m) and skating (5 and 40 m) sprint tasks. Mechanical capacities estimates include relative maximal theoretical force (F-0rel), velocity (V-0), power (P-maxrel), slope of the linear relationship between force relative to body mass and velocity (S-FVrel), maximal horizontal component of the ground reaction force to the corresponding resultant force (RFmax) and minimal rate of decrease of this ratio (D-RF). On-ice mechanical capacities (F-0rel, P-maxrel, RFmax and D-RF) largely-to-very largely correlated with 40-m skating split time (r ranging from 0.82 for D-RF to -0.91 for P-maxrel; p < 0.001). Performance variables (SJ height, 30-m running and 40-m forward skating split time) and P-maxrel demonstrated the largest associations between jumping, running and skating tasks (r ranging from -0.81 for 30-m sprint running time to 0.92 for SJ height; p < 0.001). Small (V-0, S-FVrel, D-RF and force-velocity deficit) to very large (P-maxrel) correlations (r ranging from 0.58 to 0.72; p < 0.05) were obtained between mechanical variables inferred from off- and on-ice force-velocity tests. The capacity to generate high amounts of horizontal power and effective horizontal force during the first steps on the ice is paramount for forward skating sprint performance. Mechanical capacities determined during forward skating sprint could be considered in ice hockey testing to identify fitness and/or technical/training requirements.
