Physiological Demands

To quantify the rotational demands of elite female field hockey with respect to position. Twenty-eight (n = 28) elite international field hockey players were recruited during the 2018–2020 seasons. Players were monitored with GPS technology and heart-rate monitors. Methods: Activity was categorised into total distance (m), relative total distance (m·min−1), high-speed distance (m; 16 km∙h−1), relative high-speed distance (m·min−1), max velocity (km·h−1), and percentage maximal velocity (%Vmax). Physiological demands were assessed via heart rate measures (bpm and % HRmax) and time > 80% heart rate maximum. Results: A single rotation equated to 7 ± 0.8 min. Players covered a mean total distance of was 868 ± 132 m (125.7 ± 5.9 m·min−1) with 140 ± 39 m at high-speed (21.7 ± 3.6 m·min−1). A significant difference was reported for relative total (p ≤ 0.001), and high-speed (p ≤ 0.001), distance across positional. Forwards were reported to cover the most relative total and high-speed distance (d = 1.0) when compared to defenders and midfielders. Conclusion: The study provides normative data for rotational demands of elite female field hockey. Coaches should consider these demands when developing training drills to better optimise the positional physical and physiological demands of competitive match-play.

The study examined whether the performance characteristics of male university field hockey players differed when the match format was 2 × 35 min halves compared to 2 × 2 × 17.5 min quarters. Thirty-five male university field hockey players (age 21.2 ± 3.0 years, height 1.81 ± 0.07 m, body mass 75.1 ± 8.9 kg), competing at national level in the UK, were monitored over 52 matches played across the 2018–2019 (2 × 35 min halves) and 2019–2020 (2 × 2 × 17.5 min quarters) seasons using 15 Hz Global Positioning System units and heart rate monitors. Total distance, high-speed running distance (≥15.5 km·h−1), accelerations (≥2 m·s−1), decelerations (≤−2 m·s−1), average heart rate and percentage of time spent at >85% of maximum heart rate were recorded during both match formats. Two-level random intercept hierarchal models (Match—level 1, Player—level 2) suggested that the change in format from 2 × 35 min halves (2018–2019 season) to 2 × 2 × 17.5 min quarters (2019–2020 season) resulted in a reduction in total distance and high-speed running distance completed during a match (by 221 m and 120 m, respectively, both p < 0.001). As no significant cross-level interactions were observed (between season and half), the change from 35 min halves to 17.5 min quarters did not attenuate the reduced physical performance evident during the second half of matches (total distance: −235 m less in second half; high-speed running distance: −70 m less in second half; both p < 0.001). Overall, the findings suggest that the change in match format did alter the performance characteristics of male university field hockey players, but the quarter format actually reduced the total distance and high-speed running distance completed during matches, and did not attenuate the reduction in performance seen during the second half of matches.

This investigation aimed to compare the international level peak intensity period of male field hockey players to those experienced during professional and amateur club hockey match play. Twenty-seven players from an international squad were monitored for all activity relating to field hockey over three seasons. The peak intensity period, of 3 min duration, was extracted from match play files for international and club matches. Club matches were categorised by league standard—professional vs. amateur. The output for the peak intensity period, within positions, was compared using linear mixed models (LMMs) and post hoc pairwise comparisons. Significance levels were set as p < 0.05 and Cohen’s d was utilised for effect sizes. Competition level had a main effect on relative total distance (p < 0.05) and significant interaction effects were found between competition level and position (p < 0.05). Midfielders competing in amateur leagues and international match play completed less relative total distance than those who compete in professional leagues (−47.88 m/min, p < 0.05), (−46.06 m/min, p < 0.05) with large effect sizes reported. No other position displayed significant differences for peak periods. Match play in professional leagues provide opportunities for midfielders to experience peak intensity periods of a greater magnitude than international match play.

Traditional Format

This study aimed to determine if children playing field hockey small-sided games (SSG) have different levels of physiological, performance and perceptual responses, compared to traditional hockey. Fifteen school hockey players (10–12 y) played eight matches over four months. Traditional games (n = 4) were played on a full-sized pitch with 11 players per team, and SSG were played as two-separate games (n = 8), with 7 players per team on a half-field pitch. Heart rate, movement data and match involvement were collected during the game. Participants were asked their session rating of perceived exertion (sRPE) and completed an enjoyment questionnaire. There were more possessions per player in the SSG format compared to traditional (53.9 ± 2.5 vs. 36.8 ± 6.5, [ d = 3.83]). Number of shots on goal, total goals, penalty corners and circle penetrations were increased in SSG compared to traditional games ( d = 1.11–1.83). Mean and maximum heart rate, sRPE, enjoyment, total distance run, meters per minute, distance run at low velocity and high velocity were similar for both formats, with no significant difference between them. SSG increased match involvements, allowing more participation than the traditional format, without compromising the physiological (e.g. heart rate), performance (e.g. total distance) and perceptual (e.g. sRPE) workload.

The Impact

Purpose: To examine the influence of the match period on the movement patterns of hockey players according to their playing positions under the introduction of quarters (QTRs). Methods: Sixteen subelite-level Spanish National League male hockey players participated in the study (age: 25.5 [2.9] y; body mass: 74.6 [5.5] kg). Global positioning system devices were used to monitor players’ running performance during 17 competitive matches (113 match-play profiles). Only players who played for at least 85% of the game were analyzed. Players were placed into 3 position categories: backs, midfielders, and forwards. Results: Moderate to large differences in relative total distance were found between midfielders and both backs and forwards in all QTRs (effect size [ES]: 0.4–1.2). ES for total distance was moderate for midfielders when compared with backs during the first QTR (moderate ES: 0.7). Midfielders and forwards covered more distance (m and m·min−1) in high-velocity zones than backs (ES: 0.6). Acceleration activities (n·min−1) at moderate and high intensities decreased in all groups across QTRs with moderate to very large ES (ES: 0.4–1.4). Relative sprinting distance decreased in backs (ES: 0.8). Backs had fewer repeated-sprint bouts (n and n·min−1) as the game progressed (ES: 1.0). Conclusions: During competitive match play, a degree of positional variation can be observed across QTRs. The relative distance and the number of accelerations and decelerations at moderate and high intensity decreased across QTRs. No between-QTRs differences in high-speed activity were reported.

The aims of this investigation were to describe the physical output of hockey relative to possession status, and to identify differences in physical output during each possession category with respect of match result. Ten international matches were analysed utilizing Sportscode to identify in and not in possession instances. 24 players (age 26 ± 4) wore a 10 Hz GPS device to track physical output. Linear Mixed Models and post hoc pairwise comparisons were utilised to compare the physical output in each possession category within each position and relative to match result. Significant main effects were found for possession status on several physical output metrics (p ≤ 0.05). For all positions except forwards, not in possession instances were more physically demanding than in possession instances for metrics such as relative total distance, explosive distance, and high-speed running (>5.5 m.s−1). No significant difference was identified between possession category physical output aligned with match result (p > 0.05). This study shows for the first time that not in possession instances were more physically demanding than in possession instances for defenders, outside backs and midfielders. For not in possession instances, relative total distance and high-speed running was, on average, 13% and 41% higher compared to in possession instances. Furthermore, there was no statistical difference in physical output for any position during each possession category relative to the match result.

Physiological Demands

Los entrenadores y preparadores físicos deben conocer las demandas físicas y fisiológicas del hockey hierba para poder programar los entrenamientos orientados a las necesidades de la competición. El objetivo del estudio fue analizar los patrones de movimiento en competición en jugadoras de hockey hierba en a lo largo de los cuatro periodos de partido. Participaron 18 jugadoras (22.8 ± 2.9 años), las cuales fueron monitorizadas mediante GPS y pulsómetro. Las jugadoras recorrieron 6668 m, de los cuales 276 fueron a alta intensidad (>18 km·h-1), con una velocidad media de 99.33 m·min-1 y se realizaron 7.28 sprints (>20 km·h-1) por partido. Las jugadoras que completaron todo el partido disminuyeron la distancia recorrida en el último cuarto (p < .001), no siendo así en las sustitutas. La frecuencia cardiaca máxima alcanzada en el último cuarto fue menor que en los anteriores (p < .001). Podemos considerar el hockey como un deporte de intensidad intermitente capaz de producir fatiga, por lo que los cambios rotatorios en el partido deben ser bien gestionados por los entrenadores.Abstract. Coaches and physical trainers must know the physical and physiological demands of field hockey to be able to tailor trainings based on the specific competition needs. The objective of the study was to analyze the patterns of movement of field hockey players during competition throughout four match quarters. A total of 18 players (22.8 ± 2.9 years of age), were monitored with GPS and heart rate monitor. The players covered 6,668 m, 276 of which were at high intensity (>18 km·h-1); an average speed of 99.33 m·min-1 and 7.28 sprints (> 20 km·h-1) were recorded by match. Those players who played the full match decreased the distance covered in the last quarter (p <.001), substitutes not displaying that trend. The maximum heart rate reached in the last quarter was lower than in the previous ones (p <.001). We can consider hockey as an intermittent intensity sport producing fatigue, therefore coaches should manage rotational changes during match with efficiency.

Appropriate Prescription

Field hockey requires players to perform at varying intensities throughout a competitive match, involving high-speed running combined with tactical skills in order to outscore the opposition. A greater understanding of specific running demands imposed by competitive match-play may aid coaches in appropriate prescription of training and adequate recovery programmes. Purpose: to determine peak duration- and position-specific running intensities during field hockey competition, using a rolling average method. Methods: twenty one elite male field hockey players were analysed through 15Hz Global Positioning System (GPS) technology across a 16 match competitive season. Peak values for relative distance (m·min-1) and high-speed distance (m·min-1) were calculated, placed in a velocity-time curve and analysed using a rolling average method across ten different durations (1, 2, 3, 4, 5, 6, 7, 8, 9, 10 min) for each playing position. Results: Forwards and midfielders covered significantly (p < 0.05) more relative distance than defenders for averages 1 to 6, with the forwards covering the greatest maximum relative distance and high-speed relative distance. There was a substantial decrease in relative distance and high-speed distance as the length of the rolling average increased, presenting small to moderate differences between durations 4 to 10 min, with the magnitude of differences between lengths decreasing as the rolling average length increased. Conclusion: These findings suggest that match-play running demands are significantly more intense than previously reported for all positions. As forwards exhibited a greater running intensity throughout, position specific training drills should replicate the most demanding phases of field hockey competition.

The aim of this review is to investigate the common wearable devices currently used in field hockey competitions, and to understand the hockey-specific parameters these devices measure. A systematic search was conducted by using three electronic databases and search terms that included field hockey, wearables, accelerometers, inertial sensors, global positioning system (GPS), heart rate monitors, load, performance analysis, player activity profiles, and competitions from the earliest record. The review included 39 studies that used wearable devices during competitions. GPS units were found to be the most common wearable in elite field hockey competitions, followed by heart rate monitors. Wearables in field hockey are mostly used to measure player activity profiles and physiological demands. Inconsistencies in sampling rates and performance bands make comparisons between studies challenging. Nonetheless, this review demonstrated that wearable devices are being used for various applications in field hockey. Researchers, engineers, coaches, and sport scientists can consider using GPS units of higher sampling rates, as well as including additional variables such as skin temperatures and injury associations, to provide a more thorough evaluation of players’ physical and physiological performances. Future work should include goalkeepers and non-elite players who are less studied in the current literature.
