Summary: This study investigates the relationship between the development of slow component of oxygen uptake and muscle fatigue, finding that they are correlated in a time- and intensity-dependent manner. The results suggest that the slow component of oxygen uptake may depend on muscle fatigue, even if the mechanisms of reduced contractile function differ among intensities.

Summary: The aim of this study was to investigate the effects of four different natural extracts with recognized antioxidant properties on the contractile function of skeletal and cardiac muscles after prolonged exhausting exercise. The results showed that all natural extracts provided protection for both cardiac and skeletal muscles, with different degrees depending on muscle type and duration of recovery. These findings suggest that acute antioxidant supplementation can help protect against the toxic effects of prolonged exhausting exercise.

Summary: The present study aimed to investigate the effect of cold water immersion (CWI) on the recovery of neuromuscular fatigue following simulated soccer match-play. The results showed that CWI reduced both central and peripheral components of fatigue, leading to earlier full recovery of the neuromuscular function and performance indices. Therefore, CWI might be an interesting recovery strategy for soccer players.

Summary: The purpose of this study was to investigate the effect of inducing post-activation potentiation (PAP) during prolonged low-frequency force depression (PLFFD) on motor unit (MU) firing rates. The findings suggest that firing rates during PAP may be a mechanism to mitigate the effects of PLFFD, and they are strongly matched to alterations in torque.

Summary: This study investigated the relationship between physical fitness and external load determined by a local positioning system (LPS) in a simulated basketball game. The results showed significant correlations between distances covered at high decelerations and maximal sprint speed, maximal sprint speed and maximal speed in simulated games, countermovement jump (CMJ) height and sprint distance covered in simulated games, and high decelerations and maximal sprint speed/best time in the repeated sprint test (RSA). Coaches and strength and conditioning coaches should adjust training to optimize speed and jumping ability, as these factors are reflected in in-game physical performance.

Summary: This study aimed to analyze the critical external workload variables that explain sports performance in the Mexican male professional soccer League (Liga BBVA-Bancomer) and investigate the impact of match period and match outcome on workload demands. Principal component analysis (PCA) was used to select the key performance indicators, and mixed analysis of variance was conducted to explore the effects of match outcome and match period. The results showed differences in tournaments and match periods, with draw matches having the highest external workload when considering match outcome. PCA analysis proved to be a useful method for identifying the most representative variables of performance.

Summary: The purpose of this review is to summarize the scientific knowledge about acceleration and deceleration demands during football training. The analysis of 42 studies shows that different exercises elicit different demands, with small-sided games presenting higher acceleration and deceleration demands compared to circuit training and other running-based drills. Manipulating drills variables, such as reducing or increasing the number of players in small-sided games, can effectively increase or decrease the demands. Wide playing positions, such as fullbacks, are generally exposed to higher acceleration and deceleration demands. Additionally, the demands decrease as match day approaches.

Summary: Based on the ambitions set forth in the 2030 Agenda for Sustainable Development Goals, the study aimed to test the feasibility of a flexible planning and assessment process that incorporates ongoing bidirectional feedback. The findings showed that pre-established and strict planning, even when updated monthly, did not meet the current needs of learners. Therefore, the conclusion suggests that both planning and assessment should be open and flexible to exchange information mutually and support the design of tailor-made learning environments.

Summary: The aim of this study was to analyze the acceleration and deceleration demands of football players, including duration, initial velocity, and effort magnitude, without minimum effort duration. Male professional players were monitored daily for four weeks using a global position system. The frequency, initial velocities, and average and peak magnitudes of acceleration and deceleration efforts were analyzed. Variations between playing positions were observed, with differences occurring between 0.7 and 2.5 seconds. The study concludes that the measurement of accelerations and decelerations should not be based on a minimum effort duration as it may alter the actual training load of football players.

Summary: Quantifying training load is crucial for athletes to respond adequately to training and reduce the risk of injury. This study analyzed the training load of soccer players during a training week. The most demanding session of the week was three days prior to the match, while the least demanding session was the day before the match. Midweek sessions can be used for higher training loads, whereas sessions immediately before and after the match can be used for tapering or recovery.
