Motivational determinants of physical education grades and the intention to practice sport in the future
Publication . Cid, Luis; Pires, Ana; Borrego, Carla Chicau; Duarte-Mendes, Pedro; Teixeira, Diogo S.; Moutão, João; Monteiro, Diogo
Self-Determination Theory (SDT) is amongst motivational frameworks the most popular and contemporary approach to human motivation, being applied in the last decades in several domains, including sport, exercise and physical education (PE). Additionally, Achievement Goal Theory (AGT) has presented evidence of how contextual factors may influence student's behavior in this particular context. The main purpose of this study was to analyze the motivational climate created by the teacher in the classroom, students' satisfaction of Basic Psychological Needs (BPN), and how their behavioral regulation could explain PE grades and intention to practice sports in the future.
In-season internal and external training load quantification of an elite European soccer team
Publication . Oliveira, Rafael; Brito, João; Martins, Alexandre; Mendes, Bruno; Marinho, Daniel A.; Ferraz, Ricardo; Marques, Mário C.
Elite soccer teams that participate in European competitions need to have players in the best physical and psychological status possible to play matches. As a consequence of congestive schedule, controlling the training load (TL) and thus the level of effort and fatigue of players to reach higher performances during the matches is therefore critical. Therefore, the aim of the current study was to provide the first report of seasonal internal and external training load that included Hooper Index (HI) scores in elite soccer players during an in-season period. Nineteen elite soccer players were sampled, using global position system to collect total distance, high-speed distance (HSD) and average speed (AvS). It was also collected session rating of perceived exertion (s-RPE) and HI scores during the daily training sessions throughout the 2015-2016 in-season period. Data were analysed across ten mesocycles (M: 1 to 10) and collected according to the number of days prior to a one-match week. Total daily distance covered was higher at the start (M1 and M3) compared to the final mesocycle (M10) of the season. M1 (5589m) reached a greater distance than M5 (4473m) (ES = 9.33 [12.70, 5.95]) and M10 (4545m) (ES = 9.84 [13.39, 6.29]). M3 (5691m) reached a greater distance than M5 (ES = 9.07 [12.36, 5.78]), M7 (ES = 6.13 [8.48, 3.79]) and M10 (ES = 9.37 [12.76, 5.98]). High-speed running distance was greater in M1 (227m), than M5 (92m) (ES = 27.95 [37.68, 18.22]) and M10 (138m) (ES = 8.46 [11.55, 5.37]). Interestingly, the s-RPE response was higher in M1 (331au) in comparison to the last mesocycle (M10, 239au). HI showed minor variations across mesocycles and in days prior to the match. Every day prior to a match, all internal and external TL variables expressed significant lower values to other days prior to a match (p<0.01). In general, there were no differences between player positions. Conclusions: Our results reveal that despite the existence of some significant differences between mesocycles, there were minor changes across the in-season period for the internal and external TL variables used. Furthermore, it was observed that MD-1 presented a reduction of external TL (regardless of mesocycle) while internal TL variables did not have the same record during in-season match-day-minus.
The quantification of absolute and relative training and match data across a typical microcycle utilizing a match day minus approach: A case study examining female professional soccer players

This study aimed to quantify the absolute and relative data across a typical microcycle (MC) in female professional soccer players utilizing a match day minus (MD-) approach. Ten players (24.7 ± 2.6 years) from an elite female Portuguese team participated in this case study. Data was analyzed in absolute or relativized values (per minute) and included the following metrics: duration, total distance, high-speed running distance (HSR, >15 km/h), number of accelerations (ACC, >1–2 m.s−2 [ACC1]; >2–3 m.s−2 [ACC2]; >3–4 m.s−2 [ACC3]; >4 m.s−2 [ACC4]) and decelerations (DEC, <1–2 m.s−2 [DEC1]; <2–3 m.s−2 [DEC2]; <3–4 m.s−2 [DEC3]; <4 m.s−2 [DEC4]). Total distance showed a significant difference between MD-4 and MD-2 (p = 0.047, moderate effect), which presented the lowest value of all MC days, while MD presented the highest value of HSR compared to all training days (p < 0.001, large to very large effect) for both absolute and relativized data. Relative data showed higher values for MD-5 with significant differences during MD-2 for ACC1, ACC2, DEC1, and DEC2 (p < 0.01, large to very large effect), while absolute data showed higher values during MD-4 for ACC2, DEC1, and DEC2 (p < 0.01, large to very large effect). Absolute ACC3 was higher during MD-3, denoting significant differences from MD-2 (p = 0.002, large effect). This study highlighted that it is possible to train, in specific sessions, with identical loading patterns of match play, specifically for ACC and DEC metrics. However, HSR distance was found to be higher during MD, while training values were significantly lower.
