Hip Flexion

The aim of this study was to determine the acute effect of simulated field hockey match-play on isometric knee flexion, adductor (ADD) and abductor (ABD) strength, adductor/abductor (ADD/ABD) strength ratio, countermovement jump height (CMJ), hip flexion and ankle dorsiflexion range of motion (ROM). Thirty competitive female field hockey players (23.0 ± 3.9 years old) participated in the study. Apart from the afore-mentioned variables, external (through GPS) and internal load (through RPE) were measured before (pre-match) and immediately after simulated hockey match-play (post-match) in both limbs. Isometric knee flexion strength (+7.0%, p = 0.047) and hip flexion ROM (+4.4%, p = 0.022) were higher post-match in the non-dominant limb, while CMJ values reduced (−11.33%, p = 0.008) when comparing from pre-match data. In addition, no differences were observed for isometric hip ADD, ABD, ADD/ABD strength ratio, passive hip flexion ROM and ankle dorsiflexion ROM test. A simulated field-hockey match produces an increment in hip isometric strength and hip flexion ROM values in the non-dominant limb and a decrease in jump height capacity. As a result, CMJ assessment should be considered post-match in order to identify players who would require further rest before returning to training.

Background Groin injuries are some of the most common injuries tennis players suffer. Several factors (e.g., post-match decrease in hip adductor (ADD) strength) have been proposed as possible mechanisms for increasing the incidence of this type of injury. However, the risk factors of developing groin injuries after a tennis match have not yet been delineated. Objective The aim of this study was to determine the effect of tennis match-play on isometric ADD and abductor (ABD) strength and passive hip range of motion (ROM). Methods Twenty-six male tennis players (20.30 ± 4.98 years) took part in this study. Participants completed an evaluation of strength and flexibility hip measurements before and after a simulated tennis match. Dominant and non-dominant passive hip ROM, ADD and ABD isometric strength, and the ADD/ABD strength ratio were measured before and immediately post-match. A global positioning system (GPS) and a session rating of perceived exertion (RPE) were used to assess the locomotive demands and internal match load. Results Isometric dominant ADD strength (17.8%, p ≤ 0.01) and ADD/ABD strength ratio (11.6%, p = 0.04) were lower post-match compared to the pre-match values. No between-limbs differences were observed for isometric ADD strength, ABD strength, and passive hip ROM tests. RPE showed an expected increase between pre- vs. post-match (pre- vs. post-warming-up, 3.42 ± 2.08 vs. 5.62 ± 2.29, p < 0.01). In addition, a significant relationship between ADD strength and the volume of tennis practice per week was found, stablishing that tennis players with lower volume of training per week suffered a reduction in ADD strength in their dominant limb after match-play (r = 0.420, p = 0.04). Conclusion The assessment of ADD strength and the ADD/ABD strength ratio in the dominant limb may be considered a post-match tool that can be used to identify players who require rest and additional recovery strategies before competing again.

The aim of this study was to examine the acute effect of officiating a football (soccer) match on isometric knee flexion strength and passive hip flexion range-of-motion (ROM) in referees and assistant football referees. Twelve referees (25.3 ± 3.3 years) and twenty-three assistant referees (25.1 ± 4.8 years) underwent measurements on isometric knee flexion strength and passive hip flexion ROM before and after officiating an official football match. Referees’ and assistant referees’ running patterns were monitored during the match using GPS technology. In comparison to pre-match values, referees reduced their isometric knee flexion strength (−12.36%, p = 0.046, Effect size [ES] = −0.36) in the non-dominant limb, while no significant differences were reported in the dominant limb (−0.75%, p = 0.833, ES = −0.02). No effect of the match was found in hip flexion ROM values in dominant (−4.78%, p = 0.102, ES = −0.15) and non-dominant limb (5.54%, p = 0.544, ES = 0.19). In assistant referees, the pre-to-post-match changes in isometric knee flexion strength (dominant limb −3.10%, p = 0.323, ES = −0.13; non-dominant limb −2.18%, p = 0.980, ES= 0.00) and hip flexion ROM (dominant limb 1.90% p = −0.816, ES = 0.13; non-dominant limb 3.22% p = 0.051, ES = 0.23) did not reach statistical significance. Officiating a match provoked a reduction in isometric knee flexion strength in the non-dominant limb of football referees, while no differences were reported in assistant referees.

The purpose of this study was to contrast the practice history profiles of international field hockey players and developmental activities leading to the attainment of high levels of perceptual-cognitive performance. Twenty-three international hockey players were assigned to a high performing or low performing group based on coach rankings of their perceptual and decision-making skill. Participants completed a practice history questionnaire assessing the number of hours in total practice, match play, coach-led practice, individual practice and peer-led play. Results showed that high performing players accumulated greater hours in total practice, match play, and coach-led practice compared to their low performing counterparts. Match play and coach-led practice are influential factors in the development of perceptual-cognitive performance. Diversification of sporting activities during participant’s development years did not have a negative consequence on the acquisition of hockey-specific perceptual-cognitive skills.

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.

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.
