    Effects of match location, match result and the quality of opposition in training load on a two-matches week in a top-class elite European soccer team
    (Universidad de Murcia. Servicio de publicaciones, 2021) Oliveira, Rafael; Brito, João Paulo; Loureiro, Nuno; Padinha, Vítor; Ferreira, Bruno; Mendes, Bruno
    The aim of this study is to analyseeffects of match location, match result and level of opponents in training load on the two following days of the match (MD+1; MD+2) in a top-class elite soccer European team. Nine players participated in this study. Total distance covered, distances of different exercise training zones (1–5) and average speed (AvS) were analysed. The session rating of perceived exertion (s-RPE) and Hooper Index scores (fatigue, stress, sleep quality, delayed onset muscle soreness-DOMS) were also analysed. Data was analysedregarding the two following days of a match. All weeks analysed included two matches. The results showed lower values of DOMS, effect size (ES)= 1.69, and fatigue ES=1.25, on the day following an away-win match than a home-defeat match against a bottom level opponent (all, p<0.05). It was also observed higher values of sleep quality ES=1.44, zone 1, ES=-4.35, and AvS, ES=-12.65, but lower values of s-RPE, ES=3.52, on the day following away-win match against a national top-level opponent (TLO). Finally, higher values for zone 3, ES=1.71, and lower value for AvS, ES=-6.06 were observed on the day following away-win match than a home-defeat match against champions league opponent number 1 (all, p<0.05). Total distance, AvS and zone 4 were higher after playing national opponents and/or champions league opponents in MD+1 than MD+2. The pattern of training load seems to be affected by situational variables. In general, the higher the quality of the opponents, the higher Hooper index in MD+1. S-RPE seems to be higher after playing a bottom level opponent when compared with the other opponents. Also, after playing national opponents, total distance, zones 1 and 4 were higher than against international opponents.

    Impact of Contextual Variables On The Representative External Load Profile Of Spanish Professional Soccer Match-Play: A Full Season Study
    (Wiley, 2020-05-12) Oliva-Lozano, José M.; Rojas-Valverde, Daniel; Gómez-Carmona, Carlos D.; Fortes, Víctor; Pino Ortega, José; Actividad Física y Deporte
    The aims of this study were to: (1) identify the representative external load profile of match-play in Spanish professional soccer players by principal components analysis (PCA), and (2) analyse the effect of match location (home vs away), match outcome (win vs draw vs loss) and length of the microcycle (5 vs 6 vs 7 vs 8 vs 9 days) on the external load profile. Data were collected during one season consisting of 42 matches in LaLiga 123 and 11 external load variables were selected after the PCA. TD, total distance covered; DIS0–6: distance from 0 to 6 km/h; DIS21–24: distance from 21 to 24 km/h; HSRD: high-speed running distance above 21 km/h; HSRA: total of high-speed running actions above 21 km/h; VMAX: maximum speed in km/h; Sprints: total of actions above 24 km/h; ACC: total of accelerations; ACCG-avg: average accelerometer G-force; ACCMAX: maximum acceleration (m/s2); DECMAX: maximum deceleration (m/s2). Match location had an impact on HSRD (p < 0.01; ES = 0.05), DIS0–6 (p < 0.01; ES = 0.05), and ACCMAX (p < 0.01; ES = 0.05). Match outcome had a relation to TD (p < 0.01; ES = 0.05), DIS0–6 (p < 0.01; ES = 0.05) and HSRD (p < 0.01; ES = 0.05). Length of the microcycle had an impact on TD (p < 0.01; ES = 0.05), DIS0–6 (p < 0.01; ES = 0.11), ACC (p < 0.01; ES = 0.04) and VMAX (p < 0.01; ES = 0.04). This study provides coaches a selection of variables for match-play analysis, which could represent two-thirds of external load profile. Then, professionals should consider that these contextual variables could have an impact on the external load profile.

    Influencia de las variables contextuales en la intervención del portero de hockey patines en la falta directa
    (Murcia: Servicio de publicaciones de la Universidad de Murcia, 2020) Trabal Tañà, Guillem; Daza, Gabriel; Arboix Alió, Jordi
    El objetivo del presente estudio fue analizar elefecto de las variables contextuales del partido en la intervención del portero de hockey patines durante las faltas directas. Se realizó un estudio documental basado en la Ok Liga 2015-16 y fueron analizadas todas las faltas directas (n=637). Los datos fueron recogidos de las actas de juego de la Real Federación Española de Patinaje. Se analizaron las variables contextuales: minuto de partido, estado del marcador, momento de la temporada, importancia de la falta directa y localización del partido. Se realizó un análisis correlacional mediante la prueba chi cuadrado de Pearson para identificar la relación entre las variables del estudio y la eficacia del portero. Los resultados constataron que el minuto de partido presenta una relación significativa con la eficacia del portero (χ2= 17,665; Sig.=,04; p <,05; w = ,167).un aumento de la frecuencia de faltas directas en los momentos finales, el 43,96% son lanzadas en los últimos 10 minutos de partido, y una mejora de la eficacia del portero en los momentos críticos (77,1%). Estos resultados pueden contribuir a una mejor comprensión de la importancia de los porteros en el resultado final de los partidos de hockey patines.
