International Field Hockey Players Perform More High-Speed Running Than National-Level Counterparts

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.

PURPOSE: The aim of the study is to determine the sensitive windows related to motor skills development as well as the rate of trainability of the adolescent hockey players from the Bulgarian Youth National Field Hockey Team. METHODS: This study included 20 adolescent field hockey competitors at the national level – boys at an average age of 13.5 years. The experiment was conducted twice with the same participants at an interval of 16 weeks. They were assigned into two groups: responsive and non-responsive. Those who achieved an improvement in two or more motor tests were included in the “responsive” group. Those who did not improve their performance in the motor tests were included in the group of “non-responsive” players. RESULTS: The findings from the study show that considering the age (13.5), aerobic and anaerobic conditioning is trainable (VO2max and 30 m speed test). DISCUSION: The responsive group was determined to be of high and slow trainability, while the non-responsive one – of low and slow trainability, hence the prospects of the latter for staying in the national team are not favorable. CONCLUSION: It can be recommended that the head coach select only players of medium level trainability for the 2020 Summer Championship.

Placebo Drink

The aim of this investigation was to determine the efficacy of a caffeine-containing energy drink to improve physical performance of elite field hockey players during a game. On 2 days separated by a week, 13 elite field hockey players (age and body mass = 23.2 ± 3.9 years and 76.1 ± 6.1 kg) ingested 3 mg of caffeine per kg of body mass in the form of an energy drink or the same drink without caffeine (placebo drink). After 60 min for caffeine absorption, participants played a simulated field hockey game (2 × 25 min). Individual running pace and instantaneous speed during the game were assessed using GPS devices. The total number of accelerations and decelerations was determined by accelerometry. Compared with the placebo drink, the caffeinated energy drink did not modify the total distance covered during the game (6,035 ± 451 m and 6,055 ± 499 m, respectively; p = .87), average heart rate (155 ± 13 beats per min and 158 ± 18 beats per min, respectively; p = .46), or the number of accelerations and decelerations (697 ± 285 and 618 ± 221, respectively; p = .15). However, the caffeinated energy drink reduced the distance covered at moderate-intensity running (793 ± 135 and 712 ± 116, respectively; p = .03) and increased the distance covered at high-intensity running (303 ± 67 m and 358 ± 117 m; p = .05) and sprinting (85 ± 41 m and 117 ± 55 m, respectively; p = .02). Elite field hockey players can benefit from ingesting caffeinated energy drinks because they increase the running distance covered at high-intensity running and sprinting. Increased running distance at high speed might represent a meaningful advantage for field hockey performance.

Repeat Sprint Ability

This study investigated the physical characteristics, match demands and their relationships in elite-level male field hockey players (n = 23; 24 ± 3 years). Testing data were collected to investigate the physiological profiles of the players, while match demands were quantified with GPS data over 26 matches. There were significant differences (p = <0.05) between positional groups for pull ups, relative and absolute lower body strength, and body composition. Average total match distance for all the players was (5420 ± 1518 m). There were significant differences between positional groups for defenders (5770 ± 1419 m) vs strikers (4739 ± 1409 m) and midfielders (5549 ± 1545 m) vs strikers. The most high-speed-running (>4.5 ms−1) distance was covered by midfielders (950 ± 275 m) and strikers (908 ± 284 m). Midfielders (116 ± 15 m min) and strikers (120 ± 20 m min) achieved higher intensities during matches compared to defenders (105 ± 13 m min). There were small differences between positional groups for physiological variables, but large variation between positional groups for match demands. There was a significant negative relationship between 2.4 km time trial vs high-speed running (p = <0.05), player load.min and match speed (p = <0.001). Also, there was a negative association between repeat sprint ability total time and high-speed running distance (p = <0.02) and match speed (p = <0.02). The countermovement jump height was associated with match speed (p = <0.05) and there was a negative relationship between body fat % and match speed (p = <0.02). When considering key performance indicators while using GPS devices, match speed (m.min) provides the most valuable information in field hockey players.

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.

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.
