Effects of puck mass on shot velocity of female ice hockey players

Lomas, Sarah A. January 2004 (has links)
The purpose of this study was to examine the effect of puck mass on shot velocity of female ice hockey players. The contributions of upper body strength and skill level to shot velocity were also examined. Female varsity and recreational players (n = 29, age = 21.3 yr) performed shooting tests on ice. The participants shot 20 light weight (5 oz) and 20 regulation (6 oz) pucks, using 4 different types of shots (standing wrist shot, standing slap shot, skating wrist shot, skating slap shot). The on-ice tests were followed-by 3 musculoskeletal tests; predicted 1 repetition maximum (1 RM) bench press, hand grip, and sit-ups. The light weight puck resulted in a significantly higher velocity compared to the regular weight puck (P < 0.05). The average shooting velocity was 1.4 km/h higher with the light weight puck compared to the regular puck (69.8 vs. 68.4 km/h) based on overall means (4 shots x 2 pucks). Positive correlations were found between overall shot velocity and musculoskeletal tests of hand grip (r = 0.81), predicted 1 RM bench press (r = 0.77), and sit-ups (r = 0.48). These results are discussed in relation to literature on the women's ice hockey and physiology.

Durability of ice hockey helmets to repeated impacts

Hakim-Zadeh, Roghieh January 2002 (has links)
This study evaluated the mechanical durability of ice hockey helmets for multiple impacts at defined energy levels. A monorail drop testing apparatus was used to conduct controlled impact tests according to the CSA standard (CAN/CSA-Z262.1-M90). Five ice hockey helmet models were tested, for a total sample of 45 helmets. All helmets were impacted up to 50 times at each of in four different locations (i.e. front, right side, back, and crown), at one of 40, 50 or 60 J of kinetic energies. In general, by increasing the impact energy, the impact acceleration attenuation properties of the helmets was decreased significantly (from 4% to 80%). Although all the helmets meet the CSA standards, attenuation properties were found to be substantially reduced beyond three repeated impacts and above 40 J impact energy. In particular, all helmets showed effective multiple impact attenuation properties at the crown, front, and rear sites; however, poor multiple impact attenuation durability was evident at the side.
