“…The latter author, however, did not report the interval between CK collection and team training. In relation to LDH, Bezerra et al (2016) found resting values close to those of the present study and reported that the interval between the final training and collections was 24 h, suggesting that the values found were influenced by the daily training. Ispirlidis et al (2008) , when evaluating professional soccer players, pre- and post-game, found CK and LDH resting values below 200 U/L, however the author states that the athletes did not practice any strenuous activity for 7 days before and after the game.…”

Purpose: Training methods based on small-sided game (SSG) seem to promote physiological and tactical benefits for soccer players as they present characteristics more specific to the game. Thus, the main objective of the present study was to analyze the hormonal, biochemical, and autonomic parameters in an acute manner and the recovery dynamics (up to 72 h after) in a SSG.Methods: Thirteen professional female soccer players participated in the study (18.8 ± 0.8 years, body mass 59.4 ± 6.2 kg, and height 1.68 ± 0.05 m). During and after the SSG session (4 min × 4 min separated by 3 min of passive interval and 120 m2 coverage per player), autonomic modulation was analyzed in the time and frequency domains using heart rate variability, and blood samples (5 ml) were collected before (0 h) and after (10 min and 24, 48, 72 h) the SSG for biochemical and hormonal analysis.Results: The SSG induced an increase effect for LF (low frequency) (92,52%; Very likely increase) and a decrease effect for HF (high frequency) values (-65,72%; Very likely decrease), after 10 min of recovery. The LF/HF increase after 10 min of recovery (386,21%; Very likely increase). The RMSSD (square root of the mean squared differences of the successive N–N intervals) and pNN50 (measure of the number of adjacent NN intervals which differ by more than 50 ms) values presented a decrease effect 10 min after SSG (61,38%; Very likely decrease and-90%; Very likely decrease). The CK (creatine kinase) values presented no changes 10 min after SSG. The LDH (lactate dehydrogenase) values presented an increase effect 10 min after the SSG (19,22%; Likely increase). Both testosterone and cortisol concentrations presented the same behavior after SSG, where no alterations were observed with after 10 min (<0,37%; Most likely trivial).Conclusion: The SSG promoted significant cardiovascular stress that was restored within the first 24 h of recovery. Parasympathetic parameters continued to increase while sympathetic parameters declined significantly during the 72 h of recovery. In addition, the reduced game did not alter biochemical or hormonal responses during the 72 h.

“…Estas ações motoras provocam um alto desgaste psicofisiológico ao jogador, caracterizando assim as demandas do atleta de futebol como intermitente de alta intensidade [1,13,14]. As demandas metabólicas do atleta devem ser avaliadas e interpretadas de forma a propiciar informações reais sobre condições dos jogadores e possíveis elaborações de estratégias de treino, bem como de aprimoramento de capacidades físicas que poderão determinar o desempenho do jogador [15].…”

O treinamento de força (TF) com restrição de fluxo sanguíneo e cargas leves possibilita obter ganhos de força similares aos do TF tradicional com cargas altas, o que pode ser uma estratégia de treino interessante para jovens futebolistas. Contudo, não é claro se esses métodos se equivalem em termos de magnitude da solicitação metabólica. Desta maneira, o objetivo deste estudo é identificar a resposta metabólica via análise de níveis de lactato em uma sessão de dois diferentes tipos de TF aplicado a jovens futebolistas. Dezoito atletas de futebol sub-20 foram submetidos a uma sessão TF, em dois modelos de intervenção: o Grupo TF com Restrição de Fluxo Sanguíneo (GRF; n=9) e o Grupo TF Tradicional (GTT; n=9). O GRF submeteu-se a 4 séries de 15 repetições a 20% de 1RM e 80% de restrição de fluxo sanguíneo, no exercício agachamento. O GTT submeteu-se a 6 séries de 10 repetições a 80% de 1RM, no exercício agachamento. Antes e após a sessão de treino foram medidas as concentrações de lactato. O teste de Frideman analisou os momentos pré e pós-treino, assim como entre grupos. Houve aumento expressivo dos níveis de lactato após o treino, independentemente do método aplicado (GRF: 1,8 ± 0,4 vs 9,8 ± 1,6 mM/dL; GTT: 1,8 ± 0,5 vs 9,6 ± 1,1 mM/dL; p ≤ 0,05 para ambos), e sem diferença entre os grupos (p > 0,05). Os dois modelos de TF produzem aumentos similares das concentrações de lactato em jovens futebolistas.Palavras-chave: desempenho atlético, biomarcadores, hipóxia.

“…Regarding its characterization, soccer has been considered an intermittent modality as its official matches require numerous motor actions, such as accelerations/decelerations, jumps and changes of direction at different intensities, and the competitive performance of players can be influenced by the interaction of different motor skills 1,2 .…”

Introduction Infrared thermography has been used in several areas, mainly in sports training, and specifically in soccer. Objectives The objectives of the study were to verify the acute effect of a displacement speed test on the skin temperature of elite female soccer players, to observe pre- and post-test thermal asymmetries, and to compare responses in the anterior and posterior regions of lower limbs. Methods Cross-sectional study that evaluated 17 soccer players of the 2018 Brazilian Championship. They were submitted to thermography before and 10 minutes after performing the displacement speed test. Thermographic images were collected using a FLIR® model 8 thermal imager and changes in skin temperature in the anterior and posterior regions of the lower limbs were analyzed, according to the areas of interest. Descriptive statistics were performed and mean and standard deviation of the temperatures of the areas of interest were analyzed. The normality of the data was verified, and then the Student’s t test for normal paired and independent samples and the Mann-Whitney test for non-normal samples were conducted, with p <0.05 being adopted for significance level. Results It was possible to observe that after the test there was an increase in skin temperature in all the regions analyzed, both on the dominant and non-dominant sides (p <0.05). Regarding the analysis of the anterior region, it was possible to observe a higher temperature (p <0.05) in the region of the tibial muscles than in the region of the quadriceps muscles. Conclusion It is concluded that thermography helps to understand the thermal responses of lower limbs after applying the displacement speed test. The study shows that thermographic evaluation can guide the organization of the training session when motor tests have previously been applied, and in the detection of abnormal overloads, helping to prevent injuries. Level of evidence IV; Therapeutic studies - Investigation of treatment results.
