The study examined the peak pressures and pressure patterns in the skate boot of hockey players during the backward cross-over stride. Fifteen flexible piezo-resistive pressure sensors (1.2 x 1.1 x 0.2cm thick) were placed on the plantar, dorsal, medial, and lateral surfaces of each foot for eight varsity level hockey players (mean +/- SD: height (m) = 1.80 +/- 0.07, weight (kg) = 87 +/- 0.06) and eight recreational hockey players (mean +/- SD: height = 1.76 (m) +/- 0.06, weight (kg) = 82 +/- 0.07). The strides were cut and the data was processed according to ability group and cross-over direction. The results demonstrated significant differences between groups in average speed, and in peak pressures on the medial and lateral surfaces of the foot (p≤0.05). The results also indicated a significant difference on the plantar surface of the foot when comparing cross-over directions (p≤0.05).

Purpose. This study quantified fit of ice hockey skate boots by measuring the pressure (MP) at the foot/ankle-to-boot interface using three skate sizes. The relationship between perceived pressure (PP), perceived comfort (PC) and measured pressures (MP) also were documented. Methods . 18 male subjects participated. Thirty piezo-resistive sensors recorded MPs from seven areas with the foot/ankle in various positions. A Visual Analogue Scale was used for subjective assessment of PP and PC. Results. Overall fit MP was estimated at 34.2 KPa though significant mixed interactions (p<0.05) occurred between areas, foot/ankle positions and sizes. MP correlations with PP, PC, and foot/ankle dimensions were low though a strong inverse relationship was identified between PP and PC (r = -0.63). Conclusions. The technology and protocol adopted was effective in discriminating "fit" between regional pressure differences as well as responsive to foot/ankle positions. Further examination of other footwear products and different populations is feasible and warranted.

The purpose of this study was to examine the three-dimensional movement profile of the blade during a stationary slap shot, as a function of blade construction properties and player skill level. A total of fifteen subjects participated in this study; eight were classified as elite and the remaining seven were recreational. Performances were evaluated by simultaneously recording the movements of the stick's lower shaft and blade with high-speed video (1000 Hz), the time and duration of stick-ground contact with two uniaxial forceplates, and time of blade-puck contact with a uniaxial accelerometer mounted within the puck. Data were analyzed with a two-way ANOVA for several dependent variables, including: linear kinematics, temporal phase data, and global angles. The results indicated that elite shooters tended to alter timing parameters (i.e. phase length), magnitude of linear variables (i.e. displacement, etc.), and the overall blade orientation to achieve a higher velocity slap shot. These analyses helped to identify a unique rocker phase within the execution of the slap shot in both groups. Further studies are needed to discern the precise role and function of the rocker phase, in order to advance the cause of hockey stick, specifically blade design and development.
