The standing broad jump (SBJ) is a primary condition premise for high ice-hockey skating acceleration and speed during office conditioning protocols, including the HNL draft. However, the SBJ itself might be influenced by subject anthropometry, body composition, and ability of horizontal force production, which might favor some players. Purpose: The purpose of this study was to find out which conditioning constraints are consequently related to SBJ and skating performance. Methods:
A total of 72 ice hockey players (age 17.79 6 0.59 years; height 179.79 6 4.94 cm; body mass 77.93 6 7.42 kg) from the Czech junior league were measured for full anthropometry, countermovement jump, SBJ, 30s Wingate test, on-ice 4 m acceleration, 30 m sprint, Illinois agility and 6 3 54 m during a preseason period. The countermovement and broad jump were done on 3 axis force plate (Kistler, Winterthur, Switzerland), photocells (ALGE-Timing GmbH, Lustenau, Austria) were used to measure on-ice performance, and anthropometry was performed by the International Society for the Advancement of Kinanthropometry guidelines. Testing was realized in 2 days, where 1 day included all on-ice tests and the second-day off-ice tests. The Pearson correlation coefficient was used to find out the relationships between all performances. Results:
The SBJ performance correlated with 4 m acceleration (r = 20.484; p = 0.001) and 30 m sprint time (r = 20.452; p = 0.003), where SBJ relative horizontal impulse correlate with 30 m sprint (r = 0.386; p = 0.013) and relative vertical impulse not (r = 20.155; p = 0.341) (Figure 1). Another relation of 30 m skating was with femoral epicondyle wide (r = 20.384; p = 0.001) and thigh circumference (r = 20.354; p = 20.001) and body fat (r = 0.394; p = 20.001). Other relationships showed marginal or no correlations. Conclusions: The ability to produce quick horizontal force (impulse) is the determinant of long jump and on-ice skating performance, where this ability is supported by thigh mass volume and femoral epicondyle wide. The fat percentage decreases on-ice and broad jump performance, and vertical impulse does not significantly influence skating performance. Practical Applications: Training in horizontal strength, power, and volume is crucial for ice hockey speed development and broad jump performance, which is a very good predictor of ice-hockey skating acceleration and speed. Ice hockey conditioning coaches should use
SBJ and other horizontal vector exercises to support skating performance. The thigh volume training is would support skating performance, while players should be aware of increasing body fat.
