- Internal training and match load quantification of one-match week schedules in female first league Portugal soccer teamPublication . Fernandes, R.; Oliveira, Rafael; Martins, Alexandre; Brito, JoãoTraining load (TL) quantification allow coaches to a better load management during training sessions to be in the best physical fitness to the next match. The aim of this study was to compare session rated of perceived exertion (sRPE) and Hooper Index (HI) between training and match days from the same women’s Portuguese League team. Sixteen players with a mean±SD age, height and weight of 24.0±2.9 years, 164±4.1 cm and 58.5±8.2 kg, respectively, participated in this study. The participants completed ≥80% of the training sessions during 2019/20 in-season. Data was collected through the s-RPE and the HI that measured sleep quality, fatigue, stress, and muscle soreness (DOMS). Data was analysed in relation to the number of days away from the competitive one-match week (i.e., match day minus, MD-) with three training sessions a week (MD-5; MD-4; MD-2). The study analysed data from a total of 12 matches and 45 training sessions with repeated measures ANOVA, p≤0.05. Results showed differences between MD- 5 (85.2±0.3min) vs MD-4 (87.2±0.4min) vs MD-2 (80.6±0.6min) vs MD (62.8±4.9min), all p<0.05; s-RPE showed higher values on MD-5 (503.8±19.0au) vs MD-4 (473.2±14.8au) vs MD-2 (362.1±12.1au) vs MD (468.2±40.5au); HI showed higher values on MD-5 (13.4±0.5au) vs MD-4 (13.4±0.4au) vs MD-2 (12.7±0.5au) vs MD (11.9±0.4au); DOMS revealed difference between MD-4 vs MD-2 (3.1±0.2 vs 2.7±0.2au), p<0.05. It was shown that there is a higher TL on MD-5 and MD-4 compared with MD-2. Results from HI showed that sleep, fatigue, stress and DOMS was well fair controlled by coaches and staff.
- Quantificação da carga interna no período preparatório e competitivo em semanas com um jogo numa equipa de futebol masculina sub-17Publication . Oliveira, Rafael; Brito, João; Martins, AlexandreO objetivo do estudo foi comparar a carga interna (CI) dos períodos preparatório e competitivo de jogadores sub-17 da mesma equipa. A perceção subjetiva de esforço foi recolhida em 19 jogadores e multiplicada pela duração da sessão (s-RPE). O estudo analisou um total de 2 jogos e 8 sessões de treino através da aplicação da ANOVA com medidas repetidas. Os principais resultados revelaram valores mais altos na pré-epoca na duração do treino (103,3 vs 90,0 min, p<0,001) no MD-5 e (103,7 vs 96,7 min, p>0,05) no MD-3 do que na época competitiva, respetivamente. A duração da sessão revelou ser mais baixa na pré-época no MD-4 (103,2 vs 112,0 min, p=0,013) e no MD-2 (84,0 vs 97,2 min, p<0.001) do que na época competitiva, respetivamente. A s-RPE apresentou valores mais elevados na pré-epoca comparativamente à época competitiva no MD-5 (725,5 vs 481,3 u.a., p<0,000) e no MD-3 (755,8 vs 655,2 u.a., p=0,031), mas inferiores no MD-4 (705,2 vs 821,3 u.a., p=0,002) e no MD-2 (476,0 vs 559,0 u.a., p=0,020), respetivamente. Este estudo apresenta relevante informação adicional sobre a carga interna para os períodos preparatório e competitivo que pode ser usada para ajustar a periodização em jogadores de futebol sub-17.
- Proceedings of the International Seminar of Physical Education, Leisure and Health,Publication . Oliveira, Rafael; Brito, João; Martins, AlexandreThe aim of this study was to compare internal training load (ITL) of starters versus non-starters from the same under-17 soccer team. Rated of perceived exertion was collected and then multiplied by training or match duration (s-RPE) from twenty-three soccer players. The study analysed a total of 2 matches and 8 training sessions during the in-season with ANOVA with repeated measures. The main results showed higher values in pre-season for training duration (103.3 vs 90.0 min, p=0.000) in MD-5 and (103.7 vs 96.7 min, p>0.05) in MD-3 than in-season, but lower values for training duration (103.2 vs 112.0 min, p=0.013) in MD-4 and (84.0 vs 97.2 min, p=0.000) in MD-2 than in-season. s-RPE was higher in pre-season than inseason (725.5 vs 481.3 a.u., p=0.000) in MD-5 and (755.8 vs 655.2 a.u., p=0.031) in MD-3 but lower (705.2 vs 821.3 a.u., p=0.002) in MD-4 and (476.0 vs 559.0 a.u., p=0.020) in MD-2 than in-season. This study present relevant additional ITL data for pre-season and in-season that could be used to adjust periodization in under-17 soccer players.
- In-season microcycle quantification of professional women soccer players—external, internal and wellness measuresPublication . Fernandes, Renato; Ceylan, Halil İbrahim; Clemente, Filipe Manuel; Brito, João; Martins, Alexandre Duarte; Nobari, Hadi; Reis, Victor Machado; Oliveira, RafaelAlthough data currently exists pertaining to the intensity in the women’s football match, the knowledge about training is still scarce. Therefore, the aim of this study was to quantify external (locomotor activity) and internal (psychophysiological) intensities, as well as the wellness profile of the typical microcycle from professional female soccer players during the 2019/20 in-season. Ten players (24.6 ± 2.3 years) from an elite Portuguese women soccer team participated in this study. All variables were collected in 87 training session and 15 matches for analysis from the 2019–2020 in-season. Global positioning variables such total distance, high-speed running, acceleration, deceleration and player load were recorded as intensity while Rated Perceived Exertion (RPE) and session-RPE were recorded as internal measures. The Hooper Index (HI) was collected as a wellness parameter. The results showed that internal and external intensity measures were greater in matches compared to trainings during the week (match day minus [MD-], MD-5, MD-4, MD-2), p < 0.05 with very large effect size (ES). In the same line, higher internal and external intensity values were found in the beginning of the week while the lowest values were found in MD-2 (p < 0.05, with very large ES). Regarding wellness, there was no significant differences in the HI parameters between the training days and match days (p > 0.05). This study confirmed the highest intensity values during MD and the lowest on the training session before the MD (MD-2). Moreover, higher training intensities were found in the beginning of the training week sessions which were then reduced when the MD came close. Wellness parameters showed no variation when compared to intensity measures. This study confirmed the hypothesis regarding internal and external intensity but not regarding wellness.
