The Relationship

The purpose of this study was to investigate the relationship between participation in minor league Canadian ice hockey and delinquency. Specifically, the study sought to compare the extent of delinquency among ice hockey players and nonathletes, and to examine the relationship between ice hockey participation and delinquency on the basis of a group of sociopsychological variables. The sample of ice hockey players was taken from the Montreal midget minor ice hockey league (15 to 16 years of age) and was further subdivided into local, inter-city, and provincial players. Delinquency was classified by type of offense, namely drugs, theft, physical violence, and vandalism. Data were obtained from anonymous, self-report questionnaires. The results indicated no significant difference in total delinquency between ice hockey players and nonathletes. However, when delinquency was categorized by type, ice hockey players reported more delinquency of a physically violent nature than nonathletes. The results also showed a differential association between a variety of sociopsychological variables and delinquency among ice hockey players and nonathletes

The purpose of this study was to investigate the energy expenditure and heart rate responses elicited in elite male midget ice hockey players during small-sided games. Nine players (aged 15.89 ± 0.33 years) participated in the study. Maximal progressive treadmill testing in the laboratory measured the relationship of oxygen consumption ([Formula: see text]) to heart rate before on-ice assessments of heart rate during six different small-sided games: 1v1, 2v2, 2v2 with support player, 3v3 with support player, 3v3 with transitions, and 4v4 with two support players. Heart rate was recorded continuously in each game. 3v3 T small-sided game was the most intense for all four intensity markers. All six small-sided games reached 89% HRmax or more with heart rate peaks in active effort repetition. These findings demonstrate that such small-sided games are considered as high intensity games and are an effective training method for ice hockey players.

Object Concussion, or mild traumatic brain injury (mTBI), is a commonly occurring sports-related injury, especially in contact sports such as hockey. Cerebral microbleeds (CMBs), which appear as small, hypointense lesions on T2*-weighted images, can result from TBI. The authors use susceptibility-weighted imaging (SWI) to automatically detect small hypointensities that may be subtle signs of chronic and acute damage due to both subconcussive and concussive injury. The goal was to investigate how the burden of these hypointensities changes over time, over a playing season, and postconcussion, in comparison with subjects who did not suffer a medically observed and diagnosed concussion. Methods Images were obtained in 45 university-level adult male and female ice hockey players before and after a single Canadian Interuniversity Sports season. In addition, 11 subjects (5 men and 6 women) underwent imaging at 72 hours, 2 weeks, and 2 months after concussion. To identify subtle changes in brain tissue and potential CMBs, nonvessel clusters of hypointensities on SWI were automatically identified, and a hypointensity burden index was calculated for all subjects at the beginning of the season (BOS), the end of the season (EOS), and at postconcussion time points (where applicable). Results A statistically significant increase in the hypointensity burden, relative to the BOS, was observed for male subjects with concussions at the 2-week postconcussion time point. A smaller, nonsignificant rise in the burden for female subjects with concussions was also observed within the same time period. There were no significant changes in burden for nonconcussed subjects of either sex between the BOS and EOS time points. However, there was a statistically significant difference in the burden between male and female subjects in the nonconcussed group at both the BOS and EOS time points, with males having a higher burden. Conclusions This method extends the utility of SWI from the enhancement and detection of larger (> 5 mm) CMBs, which are often observed in more severe cases of TBI, to cases involving smaller lesions in which visual detection of injury is difficult. The hypointensity burden metric proposed here shows statistically significant changes over time in the male subjects. A smaller, nonsignificant increase in the burden metric was observed in the female subjects.

The Relationship

Sprint and technique abilities of Para ice hockey players are of great importance to increase skating performance. To assess skating abilities, kinematics is widely used. This study had two purposes: (1) to assess two-dimensional kinematics of Para ice hockey players’ performance in the laboratory and on ice (sprint and agility) tests and (2) to quantify the relationship between the laboratory and on ice performance. Seven athletes were recruited. In the laboratory, three alternated reach tests were performed in which athletes touched the ground as many times as possible with hands, elbows, or shoulders. The sprint test consisted of 30-m skating at the highest speed starting from standstill, whereas the agility test consisted of sprinting for four left curves and four right curves. Athletes’ movements in the laboratory and on ice tests were acquired using a portable technology. In the laboratory, the best performance was realized when participants touched the ground with hand or elbow. In the sprint test, lower speed and trunk inclination were observed in the first 10 m. In the agility test, greater blade angle was observed in the left curves, compared with the right curves. Significant correlations were found between the laboratory and on ice test performance. Overall, these findings are a useful indicator of athletes’ skating abilities and could be used to increase athletes’ ability to accelerate rapidly and improve sledge manoeuvrability. For detailed player information, kinematics should still be evaluated using sport specific tests and video analysis.

Age Of Menarche

Objectives: Participation rates in women’s ice hockey is increasing in North America. Recent studies have demonstrated an increased prevalence of femoroacetabular impingement (FAI) in elite male ice hockey players, yet little is known about hip pathology of players in the National Women’s Hockey League (NWHL). The primary purpose of this study was to determine the prevalence of radiographic FAI in women’s professional ice hockey players. The secondary purpose was to analyze the relationship between the presence of radiographic cam deformity and hip ROM, clinical impingement signs and age of menarche. Methods: In this IRB-approved study, physical examination and demographic data were prospectively collected for 27 NWHL players. Alpha angles were measured on 45-degree Dunn views with an alpha angle &gt55° defined as cam-positive. Pearson correlations were performed to analyze the relationship between alpha angle and ROM measurements, clinical impingement signs and self-reported age of menarche. Players were grouped into those with and without cam impingement and group differences were assessed using the student’s t-test. Statistical significance was set at p&lt0.05. Results: Twenty-seven athletes were included in the study. Nineteen of the 27 players (70%) had radiologic evidence of cam-type impingement with alpha angle &gt55 degrees; 14 players (52%) had bilateral cam deformity. The average age of menarche was 13.9±1.5 years. There was a significant association between age of menarche and right alpha angle (R=0.57, CI [0.16, 0.81], p=0.011), as well as age of menarche and left alpha angle (R=0.48, CI [0.03, 0.77], p=0.039). There was no statistically significant association between alpha angle and any ROM measurement. Additionally, there was no difference in the incidence of clinical impingement for players with or without an alpha angle &gt55°. Conclusion: This study suggests that elite female ice hockey players have a significantly higher prevalence of cam-type morphology than the general population. The clinical significance of this radiographic finding is uncertain as the majority of these deformities seem to be asymptomatic. Interestingly, the positive association between alpha angle and age of menarche lends support to the etiological hypothesis that cam lesions are a result of activity-related stress at the proximal femoral physis. This data suggests that players with earlier menarche (and therefore earlier physeal closure) seem to be less vulnerable to the development of cam deformity of the proximal femur.

Background: A significant part of successful athletic performance is the use of peripheral vision. A divide visual attention task with a central and peripheral target was used to assess athletes with and without a history of concussion. The research suggests that both groups had the same response accuracy in the task performance. The purpose of this research was to determine if peripheral visual attention is impacted in ice hockey players who have had a history of one or more self reported concussion. Methods: Orientation discrimination accuracy of a pair of Landolt type block “C” targets was measured using a divided covert attention task on 22 collegiate level men’s ice hockey players. Stimuli were presented simultaneously at central fixation and at one of 40 peripheral locations against a bright white background for two stimulus durations (150ms and 15ms). Block “C” targets were presented at one of 4 orientations (up, down, left and right) and randomized for central and peripheral locations. Results: Overall there was a statistically significant difference in the performance at 150ms and 15ms stimuli durations; athletes had a larger area of correct responses with the 150ms stimulus duration. Athletes performed better in the horizontal meridian compared to the vertical meridian for both stimulus durations. Conclusion: The divided visual attention test results for a cohort of university level men’s ice hockey players shows a decline in area of correct responses with shorter stimulus durations. There was no difference in response accuracy between those with a history of a concussion compared to those without a previous concussion.
