“…In this experiment, evident differences in step mechanics were found, with a transition from short, single force peaks in the initial steps, evident of acceleration, to a distinct bimodal force-time pattern in the latter steps. The force-time curves of the first three steps showed force-time patterns similar to those found when sprinting [13], consistent with a ''running'' motion observed during the first few steps in acceleration, wherein the athlete pushed off against a fixed point in the ice [4,9,13].…”

The purpose of this study was to develop a portable force measurement system for ice hockey skating. The system consisted of three strain gauge pairs affixed to an ice hockey skate's blade holder with wire leads connected to a microprocessor controlled data acquisition device carried in a backpack worn by the skater. The configuration of the strain gauges simultaneously determined the vertical and medial-lateral force components experienced by the blade holder with a resolution accuracy of 1.9 N and a coefficient of variation of 9.2%. On-ice testing of this system with subjects performing forward start, acceleration, and constant velocity skating permitted unencumbered, natural movement and demonstrated clear, unambiguous signal responses, high trial-to-trial repeatability, and easy data retrieval. The practicality and accuracy of this testing approach have many applications, such as a quantitative tool for skating force assessment to aid athletes and coaches, as well as providing the means to examine other skill-specific dynamics.

“…Usually, the difference between HER and HIR ranges from 5° to 10°, HER being higher than HIR [ 59 , 61 , 63 , 64 ]. However, when the difference is higher than 10° (hip pattern III [ 30 ]), as occurred in the present study with an average difference between HER and HIR of 23° in LBP players and 16.9° in the asymptomatic ones, there is a higher predisposition to low back pain [ 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76…”

“…The push-off phase starts in the middle of the sliding phase, while leaning on the pushing leg, and involves hip external rotation, abduction, and extension, knee extension, and ankle plantar flexion. The later recovery phase of the pushing leg involves hip adduction, flexion, and internal rotation, knee flexion, and ankle dorsiflexion [ 38 , 39 , 91 ]. These technical features of skating result in very wide hip ROMs in order to achieved maximum performance.…”

“…Regarding the technical skills of IH, skating is the most important skill and represents a specific pattern of movement of this sport. Skating stride requires good levels of ankle plantarflexion and dorsiflexion, knee flexion and extension, hip extension and flexion, hip adduction and abduction, and hip external and internal rotation [ 38 , 39 , 40 ]. The repetition of skating movements may cause certain musculoskeletal adaptations in IH players such as muscular imbalances, tightness, and asymmetry, causing abnormal pelvis and spinal sagittal alignment and predisposing to LBP [ 41 , 42 , 43 , 44 , 45 , 46 ].…”

Low back pain (LBP) is a common ailment in competitive athletes. Although the association between limited range of motion (ROM) and prevalence of LBP has been widely investigated in other sports, there is no research about this topic in inline hockey (IH). The main purposes of this study in IH players were (1) to analyze the association between hip ROM and LBP and (2) to establish a diagnostic cutoff for ROM of high risk of LBP. Twenty elite IH players from the two Spanish National Teams (male and female) were assessed for passive maximum hip ROMs; the movement evaluated were the hip external [HER] and internal [HIR] rotation, hip flexion with flexed [HF-KF] and extended [HF-KE] knee, hip adduction with flexed hip [HAD-HF], hip abduction with neutral [HAB] and flexed [HAB-HF] hip, and hip extension [HE]. LBP was retrospectively monitored for the last 12 months before the date of ROM assessment by using a questionnaire. The data were analyzed via a binary logistic regression and receiver operating characteristic curves. The 70% of players had developed LBP during the retrospective study period. Significant differences between LBP group and asymptomatic group for HER (p = 0.013, d [Cohen’s effect size] = 1.17) and hip total rotation [HTR] (p = 0.032, d [Cohen’s effect size] = 1.05) were observed. The cutoff points with the greatest discriminatory capacity were 56.5° for HER and 93° for HTR ROMs.

Coaches and scientists share a preoccupation with understanding athletic performance. The aim of this study was to investigate coaches' practical knowledge about forward ice hockey skating with reference to the biomechanical research findings in order to improve understanding of the skating task and encourage the design of more representative research. For this purpose, 10 expert ice hockey coaches were interviewed. Semistructured interviews were transcribed and meanings units were selected and grouped to build the main categories after verbatim analysis. The qualitative analysis revealed that the coaches detailed forward skating based on three categories: posture, lower limb kinematics, and arm movements. They used performance indicators to specify their practical knowledge. These indicators were generally consistent with recent biomechanical research and when the coaches held different opinions, they expressed intuitive ideas that often suggested new research perspectives. This study illustrates how the interaction of scientists and coaches, via their respective knowledge, can supply new research perspectives.
