“…While a metabolic power approach has been used previously in other sports (Polglaze et al, 2017;Coutts et al, 2015), we acknowledge the possible underestimation of EE during match play by employing this method (Highton et al, 2016;Buchheit et al, 2015). Furthermore, data were gathered from a small sample size from one female International Touch squad during a single tournament.…”

“…13.2 ± 3.2 Kcal•min -1 ; Highton et al, 2016), it possesses a stronger association with EE (r = 0.63) than other measures such as high-speed distance (r = 0.50) or Player Load™ (r = 0.37; Highton et al, 2016). Given this method has been employed with other non-contact team sports (Polglaze et al, 2017), the metabolic power model offers a useful approach to understand the energy demands of Touch.…”

This study assessed energy intake and expenditure of international female touch players during an international tournament. Energy intake (food diary) and expenditure (accelerometer, global positioning system) were recorded for 16 female touch players during a four-day tournament, competing in 8.0 ± 1.0 matches; two on Days 1, 2, and 4, and three on Day 3. Total daily energy expenditure (43.6 ± 3.1 Kcal·kg-1 body mass (BM)) was not different (p > .05) from energy intake (39.9 ± 9.4 Kcal·kg-1 BM). Carbohydrate intakes were below current recommendations (6–10 g·kg-1 BM) on Days 1 (4.4 ± 0.6 g·kg-1 BM) and 3 (4.7 ± 1.0 g·kg-1 BM) and significantly below (p < .05) on Day 2 (4.1 ± 1.0 g·kg-1 BM). Protein and fat intakes were consistent with recommendations (protein, 1.2–2.0 g·kg-1 BM: fat, 20–35% total Kcal) across Days 1–3 (protein, 1.9 ± 0.8, 2.2 ± 0.8, and 2.0 ± 0.7 g·kg-1 BM; fat, 35.6 ± 6.8, 38.5 ± 6.4, and 35.9 ± 5.4% total Kcal). Saturated fat intakes were greater (p < .05) than recommendations (10% total Kcal) on Days 1–3 (12.4 ± 2.9, 14.2 ± 5.1, and 12.7 ± 3.5% total Kcal). On average, female touch players maintained energy balance. Carbohydrate intakes appeared insufficient and might have contributed to the reduction (p < .05) in high-intensity running on Day 3. Further research might investigate the applicability of current nutrition recommendations and the role of carbohydrate in multimatch, multiday tournaments.

“…On the other hand, when playing 6-in-9 days matches, field hockey players were able to maintain exercise intensity, without finding changes in players' physical demands as the tournaments progressed . Similarly, another study showed that field hockey players under the same congestion schedule context were capable of maintain their physical demands within and across matches (Polglaze, Dawson, Buttfield, & Peeling, 2017).…”

This 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 schedule. ResumenEl objetivo del presente estudio fue analizar el perfil de variación de las demandas físicas durante un torneo en hockey hierba, consistente en 3 partidos en días consecutivos. Díez jugadores de la liga nacional de hockey hierba participaron en el estudio (edad: 24.2 ± 2.6 años; peso: 74.2 ± 5.7 kg; altura 176.8 ± 5.1 cm). Las demandas físicas de los participantes en la competición fueron monitorizadas a través de los sistemas de posicionamiento global (SPI Elite, GPSports). La actividad fue categorizada en: distancia total (m), distancia total relativa (m·min-1), distancia a baja intensidad (LSR; <15.0 km·h-1 m·min-1); distancia a intensidad moderada (MSR; 15.1-18.9 km·h-1 m·min-1), distancia a alta intensidad (HSR; >19 km·h-1 m·min-1) y esprín relativo a minuto jugado ( NS >23.0 km·h-1/min m·min-1). El número de aceleraciones y desaceleraciones fue analizado basado en umbrales de intensidad (bajo: 1-1.9 m·s-2 n·min-1; moderado: 2-2.9 m·s-2 n·min-1; alto: >3 m·s-2 n·min-1). Las comparaciones de medias se realizaron mediante medidas repetidas (ANOVA-un factor) junto con inferencias basadas en magnitudes. Los jugadores recorrieron menos distancia a moderada y alta intensidad en el tercer partido respecto al primer partido. También realizaron menos esprines por minuto, así como aceleraciones de intensidad moderada y deceleraciones de moderada y alta intensidad entre dichos partidos. Los resultados de esta investigación sugieren que las actividades de alta intensidad son las variables más afectadas en una situación de alta densidad competitiva.Palabras clave: carga externa, demanda física, control de la carga,...

“…The classification of intensity in team sport activity is most commonly made by categorising all movements into speed thresholds [3]. The total amount (absolute) of accumulated distance achieved and the frequency, distance, and time spent within each speed threshold is then determined [4].…”

Comparing Maximal Mean and Critical Speed and Metabolic Powers in Elite and Sub-elite Soccer

et al. 2020

The quantification of maximal mean speed (MMS), maximal mean metabolic power (MMPmet), critical speed (CS) and critical metabolic power (CPmet) was conducted over full A-League (elite) and National Premier League (NPL; sub-elite) seasons. Comparisons were made between levels of soccer competition and playing positions (i. e. centre backs, full backs, central midfielders, wide midfielders and strikers). A symmetric moving average algorithm was applied to the GPS raw data using specific time windows (i. e. 1, 5, 10, 60, 300 and 600 s) and maximal values were obtained. Additionally, these maximal values were used to derive estimates of CS and CPmet. Maximal mean values, particularly during smaller time windows (i. e. 1 and 5 s), were greater in A-League match play. Only MMPmet1 was identified as being consistently different between competitions (P=<0.001–0.049) in all playing positions. Significance was only observed in CS (P=0.005) and CPmet (P=0.005) of centre backs between competitions. Centre backs were identified as the least energy demanding playing position. The present findings suggests that both maximal mean and critical analyses are suitable alternatives to common absolute distance and speed assessments of match running performance during competitive matches.
