BACKGROUND: Ice hockey is a dynamic game. We can observe collisions between the players that bring a risk of injury. There are many hockey clubs in the Czech Republic. These clubs raise great hockey players and many competing players in various levels of national leagues. The aim of this study was to map injuries in Czech hockey players and outline the situation of injury prevention and body care in ice hockey players. METHODS: We used a questionnaire survey method to obtain data. We received answers from 100 male active Czech ice hockey players, playing in the top three highest men's competitions (Extraleague - 2nd league). Individual injuries were analyzed according to specific body parts, injury type, playing position, level of competition using basic statistical characteristics and relative frequency analyses, including the recovery time, injury reason and the injury statistics per 1000 sporting performances in ice hockey. RESULTS: We found that 81% of participants suffered injuries with the overall incidence of injuries was 17.1 per 1000 sports performances and mainly happened during the match compared to training. The most common injuries were in the head and neck area (25%), often caused by a collision with another player, a stick or puck hit, or a collision with a board. Other frequently injured parts were the knees (21%), where internal ligament injuries predominate, and the shoulders (20%), where we recorded mainly ligament injuries. CONCLUSIONS: There is a high risk of various injury types of ice hockey players, that are developed accidentally in all body parts mostly in the match (mostly upper part of the body and knee) or by overloading (hip/groin area). We recommend strategies to avoid or minimize the injury risk of players. The hockey clubs, coaches, and players should extensively and regularly cooperate with physiotherapists, starting from the younger age of hockey groups, to prevent injuries and use regular strengthening of crucial muscle parts, regeneration, and compensatory exercises. We endorse adequately evaluating dangerous foul actions for referees and disciplinary officials also in minor competitions.

BACKGROUND: Ice hockey includes symmetrical as well as asymmetrical movements. As such, possible difference in mass and strength, as well as performance variables, may be observed between limbs. METHODS: We examined the relation between body composition and lower extremity anaerobic power in Czech elite ice hockey players with the inter-limb difference dependence. In total, 168 ice hockey players (age = 20.81, Q1 = 18.24, Q3 = 28.75) underwent body composition measurement and Wingate Anaerobic Test (WAnT). The dominant (D) and non-dominant (ND) leg was established. A Wilcoxon Signed Rank was used. The difference between the dominant and non-dominant lower extremities was evaluated using the dimensionless analysis and by setting the value for the dominant leg at 100%. RESULTS: The difference in muscle mass (MM), fat mass (FM), and WAnT outcome variables (MP, RAP, MP5sP) between the right and left leg was greater than the difference between D and ND leg. Less total body fat mass (TBFM) and more total body muscle mass (TBMM) and lower extremities muscle mass (LEMM) were associated with higher WAnT outcome values. The dimensionless analysis showed a statistically significant correlation between almost all variables. CONCLUSIONS: More TBMF and LEMM and less TBFM was better for WAnT. The difference between the right and left leg was greater than the difference between D and ND leg. If there is a difference between MM and FM of lower limbs than there could be difference between the power of lower limbs as well.

Background: In ice hockey, regular off-ice testing can serve as a controlling mechanism for a training program's effectiveness. Objective: The main aim of this study was to describe changes in selected morphological and physiological parameters, intended to be relevant for a complex ice hockey performance, after two months of pre-season training preparation following one month of an off-season period. Methods: The sample consisted of 22 adult male players aged 18-39 years from a top Czech ice hockey league team. Two laboratory testing procedures performed at the end of the off-season and after two months of the pre-season conditioning consisted of basic anthropometry and body composition measurements, countermovement jump (CMJ), and maximal incremental test focused on the assessment of various parameters, including maximal oxygen consumption (V̇O2max), maximal power output during the test (Pmax) or estimation of anaerobic threshold intensity (ANT). Results: After the pre-season, we found a significant decrease in body fat (13.7 vs. 11.4%, p < .001) and an increase in fat-free mass (74.2 vs. 76.6 kg, p < .001), V̇O2max (relative 48.8 vs. 52.6 ml.kg-1.min-1 p = .001; absolute 4.20 vs. 4.54 L.min-1, p < .001), Pmax (5.26 vs. 5.44 W.kg-1, p = .011), power output at ANT (4.07 vs. 4.35 W.kg-1, p < .001), and CMJ (44.9 vs. 47.1 cm, p = .002). Conclusions: Based on our results, two months of the pre-season training program led to a significant improvement in body composition and physical performance levels in professional Czech ice hockey players.

This study explores differences in the reporting of female and male sports journalists. Based on a brief review of the literature related to gender differences in sports journalism and the stereotypes associated with the work of female sports journalists, the paper identifies a purported ‘female writing style’ characterized by a focus on soft news, an emotional approach to reporting and reduced interest in statistical and analytical data. Using a quantitative content analysis, I reviewed 167 audio-visual and 50 written ice-hockey reports about Czech Extraliga produced by six sports journalists, who worked in leading Czech sports media departments. I observed the frequency with which the reporters presented statistical data, evaluated a performance, described emotions, recounted personal stories, and used original phrases. Comparing women’s and men’s output, it emerged that gender of the author did not have a dominant influence on the form of their reports and did not impact the use of specific language elements.

Hokej je v České republice velmi populární sportovní odvětví. V současné době je analýza efektivity hokejových klubů užitečným nástrojem, který pomáhá manažerům s hodnocením týmových výkonů. Existuje však omezené množství vědeckých studií, které by se zabývaly ekonomickými rozměry a hodnocením efektivity hokejových klubů. Výkony jednotlivých hráčů ovlivňují výkon celého týmu a předurčují úspěch či neúspěch samotného hokejového klubu. Cílem tohoto výzkumu je vytvořit metodiku hodnocení efektivity hokejových klubů a následně tuto metodiku aplikovat na příkladu české Tipsport extraligy. V předkládaném výzkumu byl využit model analýzy datových obalů, konkrétně vstupově orientovaný Charness, Cooper, Rhodes model. Model je empiricky aplikován k hodnocení 15 hokejových klubů Tipsport extraligy v sezóně 2021/22. V první části výzkumu byla vypočtena technická efektivita pro jednotlivé herní pozice. Na základě dílčích hodnot technické efektivity jednotlivých herních postů byla následně vypočtena celková technická efektivita celého klubu. Na základě celkové efektivity bylo stanoveno pořadí klubů v sezóně 2021/22 a porovnáno se skutečnými klubovými výsledky. Z výzkumu mimo jiné vyplynulo, že, ne vždy jsou kluby, které se dostanou do play-off, nejvýkonnější.

Hockey is a very popular sport in the Czech Republic. Nowadays, efficiency analysis of hockey clubs is a useful tool to help managers evaluate team performance. However, there is a limited amount of academic studies that deal with the economic dimensions and efficiency evaluation of hockey clubs. The performance of players affects the performance of the entire team and predicts the success or failure of the hockey club itself. The aim of this research is to develop a methodology for evaluating the efficiency of hockey clubs and then apply this methodology to the Czech Tipsport extraliga. In the present research, the data envelopment analysis model was used, specifically the input-oriented Charness, Cooper, Rhodes model. The model is empirically applied to the evaluation of 15 hockey clubs of the Tipsport extraliga in the 2021/22 season. Subsequently, the overall technical efficiency of the whole club was calculated based on the partial values of technical efficiency for each playingposition. Based on the overall efficiency, the ranking of the clubs in the 2021/22 season was then determined and compared with the actual club results. The research showed, among other things, that, not always the clubs that make the play-offs are the most efficient.

The impact of two different passive recovery durations, two and three minutes, between sets of repeated sprint skating ability (RSSA) test on skating speed, speed decrement (Sdec), and heart rate (HR) response of ice hockey forwards (n = 12) and defensemen (n = 7) were determined. Six sets of 3 × 80 m sprint, with two-minute passive recovery between two consecutive sets, were performed in RSSA-2. A three-minute passive recovery period between two consecutive sets was allowed in RSSA-3. Skating speed, Sdec, and HR were measured in all tests. Subjects skated faster (p < 0.05) in most of the RSSA-3 sets than the corresponding set of RSSA-2. Defensemen were slower (p < 0.05) than forwards in most of the cases. The Sdec was higher in defensemen than in forwards, although the difference was significant occasionally. No difference in peak HR and minimum HR between forwards and defensemen was found. RSSA-3 is beneficial over RSSA-2 in both forwards and defensemen by increasing speed. Defensemen are slower and show early fatigability than forwards, and no difference in HR response was noted between forwards and defensemen. This study concludes that three-minute recovery is beneficial over two-minute recovery by increasing skating speed, although Sdec and HR response neither vary significantly between RSSA-2 and RSSA-3, nor between forwards and defensemen.

The coronavirus pandemic has affected life and left one of the strongest negative effects on sport. The aim of our study was to evaluate how a simple exercise performed with elastic resistance during the COVID-19 pandemic, when athletes cannot train, affects the basic shooting characteristics of ball hockey players. Extra-league ball hockey players (N = 30, age 19-37 years) were randomly divided into an experimental group, which performed elastic resistance exercises with Proprioceptive Neuromuscular Facilitation (PNF) elements for eight weeks, and a control group, which did not perform any exercises. Before the start of the experiment and after it was completed, the speed and accuracy of shooting were measured. In experimental group, there was no decrease after 8 weeks in the shooting speed, and in the control group, there was a statistically significant decrease. There was a deterioration in the accuracy of shooting in both groups; however, in the experimental group, the deterioration was not significant. The results show that even three simple exercises with elastic resistance according to the PNF concept performed 10 times per day for eight weeks can maintain the level of basic skills of ball hockey players-the speed and accuracy of shooting-even when no other training is performed.

The aim of this study was to determine the effects of two different rest periods, 2 min and 3 min, between consecutive sets of a repeated sprint skating ability (RSSA) test, on the skating ability of ice hockey players. Two RSSA tests, RSSA-2 and RSSA-3, were assessed on 24 ice hockey players. In RSSA-2, six sets of 3 × 80 m sprint skating, with 2 min passive recovery between two consecutive sets was allowed. In RSSA-3, the recovery period between the sets was 3 min. Average speed, average heart rate (HRaver), peak heart rate (HRpeak), blood lactate concentration ([BLa]), and rate of perceived exertion (RPE) were measured in both RSSA-2 and RSSA-3 tests. In all the sets, except set 1, the average speed of the subjects was significantly (p < 0.05) higher in RSSA-3 than the respective set in RSSA-2. Average HR and RPE were higher in RSSA-2 than RSSA-3 in most of the sets. For any given set, no difference in HRpeak was noted between RSSA-2 and RSSA-3. Post-sprint (Set 6) [BLa] was significantly (p < 0.05) higher in RSSA-3 than RSSA-2. This study concludes that the 3 min rest period is more beneficial than the 2 min rest period, for (1) increasing skating speed and (2) reducing overall cardiac workload and perceived fatigue.

BACKGROUND: Postural control is required during various fast-paced and offensive ice hockey actions, and therefore seems to be an important component in ice hockey performance. METHODS: Data were collected from two ice hockey teams with differing performance levels. The higher-performance team consisted of 26 players (with ages of 16.3±0.9 y, heights of 178.26±6.71 cm, and weights of 74.3±9.6 kg). The lower-performance team consisted of 19 players (with ages of 16.2±1.8 y, heights of 176.11±9.81 cm, and weights of 68.7±13.9 kg). Each participant performed six unilateral stances under static conditions on a balance pad placed on a force platform and five bilateral stances under dynamic conditions using a wobble board placed on the force platform. RESULTS: The higher-level players performed better in the unilateral static stance task in both the anterior-posterior direction and the medial-lateral direction (with a P value of P<0.001), and total velocity (P=0.001). The higher-level players also performed better in both the anterior-posterior and medial-lateral directions, and total velocity (with P value of P<0.001), in the bilateral dynamic stance task and therefore performed significantly better than the lower-level players. CONCLUSIONS: Hockey players who possess a highly developed postural control strategy have a superior ability to compensate for unexpected postural disturbances and collisions, and thus possess a strong competitive advantage. Therefore, testing the balance abilities of hockey players under static and dynamic conditions may be useful for evaluating their competitive performance levels.
