Summary: This study aimed to investigate the relationship between physical fitness scores and postactivation potentiation (PAP). The results showed that athletes with higher fitness levels demonstrated a more significant response to PAP induction, and plyometrics exercises combined with sled towing sprints as a conditioning activity improved CMJ performance in athletes.

Summary: This study compares the effects of standard warm-up versus warm-up using stretching exercises on the physical performance of male youth soccer players. The results show that stretching-based warm-up has no effect on jump height, sprint speed, and ball kicking speed of male youth soccer players compared to standard warm-up.

Summary: The rise in energy drink consumption is largely driven by effective marketing targeting both the general population and athletes. Adolescents are the main consumers of energy drinks, with a usage rate ranging from 52% to 68%, while adults have an estimated usage rate of 32%. The main components of energy drinks are caffeine and taurine, and their potential synergistic effects on physical performance are still under scrutiny.

Summary: The aim of this study was to compare the effects of a short-term non-soccer-specific training and soccer-specific training on cognitive and physical performance in preadolescent soccer players. The results showed that both the non-soccer-specific training and soccer-specific training led to improvements in cognitive and physical performance. This suggests that non-sport-specific activities targeting speed, agility and quickness combined with cognitive engagement should be included in soccer training programs to promote both physical and cognitive development in preadolescent individuals.

Summary: This study examined the effects of an 8-week repeated backward running training on youth male soccer players' physical fitness. The results showed that the RBRT group improved in all performance variables, while the control group had minor to moderate negative effects on sprinting and change of direction speed. The RBRT group also had a higher percentage of individuals reaching the smallest worthwhile change threshold compared to the control group. Overall, substituting part of a standard soccer training regimen with RBRT can enhance youth soccer players' performance.

Summary: This study investigated the effects of energy drink supplementation and treadmill exercise on various factors related to lipid metabolism in rats. The results showed that treadmill exercise is important in regulating lipid metabolism and stimulating peptide hormones and receptors. Additionally, consuming energy drinks without exercise increases fat stores and poses a threat to the body.

Summary: This study investigated the aerobic capacity of professional soccer players before and after COVID-19 infection. The results showed that the infected players had lower VO2max values and VO2 values at respiratory compensation point (RC) after recovery. They also had lower running time on the treadmill and lower velocity at VO2max, but higher heart rate values at ventilatory threshold (VT) and RC post-recovery. These findings suggest that soccer players may not fully recover their aerobic capacity two months after COVID-19 infection.

Summary: This study compared the effects of repeated sprint training (RST) with and without change of direction (CoD) movements on various fitness characteristics in male youth soccer players. The results showed that both training methods were equally effective in improving repeated sprint ability (RSA), CoD speed, linear sprint speed, and aerobic endurance (AE).

Summary: The idea of increasing physical activity directly adding to total energy expenditure (TEE) in humans is challenged by the energy constrained hypothesis. Evidence supporting this hypothesis is limited due to various methodological issues, and future studies should address these limitations by using randomized controlled trials. The available evidence suggests that increasing physical activity mostly has an additive effect on TEE, although some energy remains unaccounted for, and the degree of energy balance may further moderate this effect.

Summary: This study investigated the dietary practices and energy availability of adolescent female soccer players and found that their carbohydrate intake was inadequate during training and games, which may affect their performance. However, the prevalence of low energy availability among female team sport athletes may be overestimated.

Summary: This systematic review examines the effects of n-3 PUFA supplementation on lean mass and muscle protein synthesis in individuals without physical training. The review found that n-3 PUFA supplementation had positive effects on skeletal muscle volume and mass, as well as muscle protein synthesis rate. However, there was no significant effect on the mechanisms of mTOR, Akt, and skeletal muscle gene expression.

Summary: This study investigated the relationship between different measures of eccentric hamstring strength and the gold standard measurement of eccentric hamstring strength using an isokinetic dynamometer. The results showed that all Nordic-based measurements had acceptable associations with the gold standard measurement, but the peak eccentric force measured on the Smart-Nordic device had a better agreement with the isokinetic eccentric hamstring peak torque compared to the video-based measurements.

Summary: Caffeine is widely consumed in sports for its established performance-enhancing effects. While there is ample evidence for the benefits of caffeine supplementation on endurance exercise, most of the studies have focused on cycling trials. This study aimed to systematically review and meta-analyze the effects of caffeine intake on endurance running performance.

Summary: alpha-Actinin-3 is a protein found in skeletal muscle that plays a structural role at the Z-line. The presence of a certain gene variant affects the expression of alpha-actinin-3, and individuals with functional alpha-actinin-3 have a higher frequency in elite badminton players, especially those ranked in the world's top ten.

Summary: This overview review includes 189 experimental studies with 3459 participants to describe the characteristics of research on caffeine effects on strength. Most studies used a single dose of caffeine adjusted to body mass, with a median sample size of 15 participants. Capsules and beverages were the most common forms of caffeine administration. The pattern in these studies focused on upper or lower body strength performance, with a moderate dose of caffeine.

Summary: This study examined the influence of accumulated match-play exposure on hamstring strain injury in professional football players. It found that low match-play exposures in the previous matches increased the risk of hamstring injuries. Metrics from the match before the injury showed the best accuracy in predicting injury occurrence.

Summary: In recent decades, there have been numerous studies investigating the effects of oral caffeine intake on fat oxidation. However, there has been no bibliometric analysis to assess the research activity in this field. This study conducted a bibliometric and visual analysis to assess the scientific output regarding oral caffeine intake and fat oxidation rate. The findings demonstrate that this is a nutrition research area with a strong foundational base of scientific evidence, and future research should focus on the effects of sex and caffeine tolerance on fat burning, as well as translational research in ecologically valid contexts.

Summary: This study examines the differences in playing style and technical performance based on ranking levels in Spanish football teams. Higher-ranked teams exhibit an advanced starting position, longer offensive sequences, slower progression speed, more ball possession, higher passing accuracy, and more crosses and through balls. Coaches should consider adopting a playing style focused on regaining ball possession in advanced field zones and using long passing sequences as an effective tactical strategy to improve ranking.
