Summary: This study found that caffeine supplementation can improve performance in the Wingate test and increase blood lactate concentration. However, the measurement of neuromuscular fatigue showed that caffeine had no effect. Therefore, caffeine may allow athletes to train at higher intensities and enhance the effects after an adequate recovery period.

Summary: The purpose of this study was to investigate the use of nutritional supplements among highly trained swimmers on a national talent pathway. The study found that 98% of swimmers reported using at least one supplement, with performance and recovery being the main reasons. National swimmers used more supplements, particularly ergogenic aids, compared to age-group and development swimmers. Parents/guardians were the main source of supplement information for development swimmers, while performance nutritionists played a significant role for age-group and national swimmers. The study suggests the need for supplement education for parents/guardians at the development level and further research on the efficacy of supplements used by national swimmers.

Summary: The relationship between caffeine intake and cognitive performance during exercise has gained attention. Studies suggest that low/moderate doses of caffeine before and/or during exercise can improve self-reported energy, mood, and cognitive functions like attention, as well as potentially impacting simple reaction time, choice reaction time, memory, or fatigue depending on research protocols.

Summary: This study investigated whether variations in the HTR2A gene modify the effects of caffeine on endurance and if this modification is further influenced by the CYP1A2 genotype. The results showed that 4 mg/kg caffeine improved endurance performance specifically in individuals with the HTR2A CC genotype and CYP1A2 AA fast metabolizers.

Summary: This systematic review with meta-analysis examines the effects of caffeine supplementation on combat sports performance. The results suggest that caffeine has a small but evident effect on handgrip strength and the total number of throws in judo fitness tests. It also increases blood lactate concentration and heart rate in anaerobic exercise and simulated combat. However, caffeine does not have an impact on other performance measures such as jump height, strength-endurance, offensive actions, and perceived exertion.

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: This study examined the distribution and prevalence of badminton-related pain in pre-adolescent and adolescent badminton players. The ankle was the most common site of pain, and 11-12-year-old players had the highest pain rate. Additionally, pain prevalence increased with age, and players with 2-3 years of badminton experience had the highest pain rate.

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: The introduction of the five-substitution option in professional football teams increased the number of substitutions per match but did not change the timing of the first substitution. However, it led to higher running distances at higher speeds (21.0-23.9 km/h and >= 24.0 km/h) and was associated with increased running performance by starting players rather than substitutes. This option allowed team coaches to better manage players' physical load and enhance their 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: The research aimed to study the age evolution of badminton players in men's, women's, and mixed doubles from 1994 to 2020. Data obtained from the Badminton World Federation website showed that the average age of men's and mixed doubles players increased over time, while the average age of women's doubles remained constant. Women's doubles players also reached their peak performance at a younger age than men's and mixed doubles players. These findings could provide valuable insights for coaches, trainers, and selectors in planning the athletic career of elite players.

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.
