Item Analysis of congested schedule on competition external load in field hockey.(RICYDE. Revista Internacional de Ciencias del Deporte, 2020) Romero Moraleda, Blanca; Morencos Martínez, Esther; Torres Ronda, Lorena; Casamichana, DavidThis study aimed to investigate the variation in players’ physical demands profile during a major national men field hockey tournament which consisted of 3 matches on consecutive days. Ten Spanish National League hockey players participated in the study (age: 24.2 ± 2.6 years; body mass: 74.2 ± 5.7 kg; height 176.8 ± 5.1 cm). Participants´ physical demands were monitored using global positioning system devices (SPI Elite, GPSports). Activity was categorized into total distance (m), relative total distance (m·min-1), low speed running (LSR; <15.0 km·h-1 m·min-1); moderate speed running (MSR; 15.1-18.9 km·h-1 m·min-1), high speed running (HSR; >19 km·h-1 m·min-1), sprinting relative to minute played (SR; >23.0 km·h-1 m·min-1) and number of sprints (SN; >23.0 km·h-1/ n/min). The number of acceleration and deceleration efforts were analyzed using intensity thresholds (low: 1-1.9 m·s-2 n·min-1; moderate: 2-2.9 m·s-2 n·min-1; high: >3 m·s-2 n·min-1). The data were analyzed using one-way repeated measures ANOVA coupled with magnitude-based inferences. Players reduced distance covered at moderate- and high-speed running, sprints relative minute played and the number of moderate accelerations, and moderate and high decelerations per minute played in the third match compared to the first match. The results of this investigation show that intensity activity were the most affected variables with congestion scheduleItem Demandas cinemáticas de competición internacional en el hockey hierba masculino.(Apunts. Educación Física y Deportes, 2021) Haro, Xavier; Torres, Lorena; Casamichana, David; Romero Moraleda, Blanca; Morencos Martínez, Esther; Rodas, GilEl objetivo de esta investigación fue describir las características cinemáticas durante partidos internacionales de hockey hierba masculino. Dieciséis jugadores (edad: 25.12 ± 3.66 años; altura: 177.12 ± 4.96 cm; peso: 72.45 ± 5.01 kg; internacionalidades: 79.12 ± 78.96) pertenecientes a la selección absoluta española, fueron monitorizados mediante sistemas de posicionamiento global y acelerometría durante 5 partidos del Campeonato de Europa de 2017. Los análisis se hicieron en función del cuarto de juego (C1, C2, C3 y C4), las demarcaciones (defensas, centrocampistas y delanteros), y los minutos jugados (por partido). Los datos analizados incluyeron distancias, aceleraciones y desaceleraciones en diferentes rangos de intensidad. Los defensas presentaron menor actividad cinemática a alta intensidad (velocidades, número de esprints, metros/min) respecto a medios y delanteros. El análisis por cuartos mostró que en el C1 hubo actividad cinemática mayor para todas las demarcaciones. En cuanto a minutos jugados, el análisis clúster agrupó a los jugadores en 3 grupos (<37, 37-48 y >48 minutos). Aquellos que jugaron <37 minutos, realizaron la mayor cantidad de metros a esprint (>21km/h) y de m/min en comparación con los otros grupos, mientras que los que disputaron entre 37-48 minutos, fueron los que más distancia a alta intensidad (>16km/h) recorrieron y mayor cantidad de esprints realizaron. Los resultados de este estudio muestran que las demandas físicas de los jugadores de élite de hockey hierba, dependen de la demarcación en el campo, del tiempo de juego, con mayor actividad en el C1, y con una menor actividad cinemática de alta intensidad relativa en aquellos jugadores que acumulan más minutos durante el partido.Item Demandas cinemáticas de competición internacional en el hockey sobre hierba femenino.(Apunts: Educación Física y Deportes, 2019) Morencos Martínez, Esther; Casamichana, David; Torres, Lorena; Romero Moraleda, Blanca; Haro, Xavier; Rodas, GilObjective. To compare the kinematic demands on international women field hockey players during official competition matches. Materials and methods. Sixteen women players (age: 24.7 ± 2.8; weight: 57.9 ± 5.9 kg; height: 165.2 ± 4.9 cm) belonging to the Spanish national team were monitored during 5 matches of the European Championship using global positioning systems (GPS). The analyses were carried out according to the players’ positions (defenders, midfielders and forwards), the quarters in the game (Q1, Q2, Q3, Q4), and the number of minutes played. The data analysed included distances, accelerations and decelerations in different intensity ranges. Results. The defenders showed less high-intensity activity (speeds, accelerations and decelerations) than midfielders and forwards (9.4 ± 2.4%; ES: 0.78 with the midfielders and 33.1 ± 7.2%; ES: 2.1, with the defenders). The analysis by quarters showed that in Q4 activity was the highest for all positions. In terms of the number of minutes played, the cluster analysis grouped the players into 3 groups according to the number of minutes played (<32, 32-45 and >45 minutes). The athletes who played <32 covered the greatest distance at a sprint (>21 km/h) and high-intensity distance (>15 km/h) per minute of play compared to the group who played >45 minutes. Conclusions. The results of this study show that the physical demands on élite women hockey players depend on their position on the field, and that there is more activity in the last quarter and less relative high-intensity kinematic activity among the players who play more minutes during the match.Item External and internal loads during the competitive season in professional female soccer players according to their playing position: differences between training and competition.(Research in Sports Medicine, 2021) Romero Moraleda, Blanca; Nedergaard, Niels J.; Morencos Martínez, Esther; Casamichana, David; Ramírez Campillo, Rodrigo; Vanrenterghem, JosThe aim of this study was to compare external (EL) and internal loads (IL) during training sessions compared to official matches between elite female soccer players according to their playing position. Training and match data were obtained during the 2017/18 season from eighteen players (age: 26.5±5.7 years; height: 164.4±5.3 cm; body mass: 58.56±5.58 kg) from a first Division Spanish team. The EL (total distance covered; high-speed running distance; number of accelerations and decelerations) was assessed with a Global Positioning System (GPS) and triaxial accelerometer. The IL was assessed with ratings of perceived exertion (RPE; and session-RPE). The EL and the IL from official matches were higher compared to training sessions (p<0.05; effect size [ES]:0.6–5.4). In matches, the EL was greater in Attackers (AT) and Central Midfielders (CM) versus Central Backs (p<0.05; ES:0.21–1.74). During training sessions, the EL was similar between playing positions (p>0.05; ES:0.03–0.87). The EL and the IL are greater in matches compared to training sessions, with greater match-related EL in AT and CM players. Current results may help practitioners to better understand and modulate training session’s loads according to playing position, potentially contributing to their performance readiness and injury risk reduction.Item Positional comparisons in the impact of fatigue on movement patterns in hockey.(International Journal of Sports Physiology and Performance, 2018) Morencos Martínez, Esther; Romero Moraleda, Blanca; Castagna, Carlo; Casamichana, DavidThe aim of this study was to examine the influence of match period on the movement patterns of hockey players according to their playing position under the introduction of quarters. Methods: Sixteen sub-elite level Spanish National League male hockey players participated in the study (age: 25.5 ± 2.9 years; body mass: 74.6 ± 5.5 kg). Global Positioning Systems (GPS) 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 categorized into three positions: backs, midfield and forwards. Results: Moderate to large differences in relative total distance were found between midfielders and both backs and forwards in all quarters (ES: 0.4-1.2). ES for total distance was moderate for midfields compared to backs during the first quarter (moderate ES: 0.7). Midfields and forwards covered more distance (m and m·min-1) in high velocity zones compared to backs (ES: 0.6). Acceleration activities (n·min-1) at moderate and high intensities decreased in all groups across quarters with ES moderate-to-very-large (ES: 0.4-1.4). Relative sprinting distance decreased in back players, (ES: 0.8). Backs sprinted had fewer repeated sprint bouts (n and n·min-1) less as game progressed (ES: 1.0). Conclusions: During competitive match-play a degree of positional variation can be observed across the quarters. The relative distance and the number of accelerations and decelerations at moderate and high intensity decreased across the quarters. No between quarters differences in regards to high-speed activity were reported.Item The use of generic and individual speed thresholds for assessing the competitive demands of field hockey.(Journal of Sports Science and Medicine, 2018) Casamichana, David; Morencos Martínez, Esther; Romero Moraleda, Blanca; Gabbett, Tim J.The current study compared the running demands of professional field hockey players using individualized speed zones and generic default settings of the GPS manufacturer. In addition, the differences in slow, moderate and fast players were studied. Sixteen male players from the same club participated in the study (age: 25.5 ± 2.9 years; body mass: 74.6 ± 5.5 kg; stature 1.77 ± 0.05 m). The peak speed of each participant was established at the end of the data collection period by analyzing all training and playing data throughout the season. Using players peak speed achieved for each participant during the season, individualized speed zones were retrospectively applied to all match-play data. Peak speed was used to categorize players into three groups, slow (5 players: 29.2-30.2 kmꞏh–1), moderate (6 players: 30.7-31.5 kmꞏh–1) and fast (5 players: 32.2-33.7 kmꞏh–1). Significant differences were observed between generic and individual thresholds for the distance covered in moderate, high, and very high-speed running in all positions (p = 0.01). Our findings show that the distances covered at high-speeds in midfielders and forwards were overestimated, while the very high-speed running and sprinting in backs were underestimated. Generic speed thresholds should be used if comparisons between positions is of importance. However, based on the different capacities of field hockey players, individual speed thresholds may be more suitable when addressing the relative stress on individual athletes.
