“…Moreover, a recent study ( 13 ) found that effective playing time should be considered when interpreting the match running performance on professional soccer players, as non-significant differences on high-speed running and sprinting distances were found between the 1st and 2nd halves in professional soccer players when the effective playing time was considered. Lastly, another study ( 36 ) showed that total distance and relative total distance significantly decreased in seasons with VAR compared to seasons without VAR in the top Spanish professional football league. Consequently, higher effective playing time may increase the physical match demands, but more research is warranted on this topic.…”

Effective playing time has been debated as a topic of major concern in football. Thus, the current experimental study aimed to investigate the effects of effective playing time on technical-tactical and physical match parameters in football. One hundred and seventy-nine male highly trained football players (aged 27.9 ± 5.1 years) from twelve teams performed two different match-play conditions: 45 min of match-play without stopping the chronometer (T45), and 30 min of match-play by stopping the chronometer every time the ball was out-of-play (T30). T30 presented a significantly higher total time (49:30 vs. 45:00 min; p = <.001; ES = 0.76), effective playing time (28:70 vs. 26:80 min; p = <.001; ES = 0.62), and stopped time (20:60 vs. 18:20 min; p = 0.003; ES = 0.38) compared to T45. Total ball possession (54.4% vs. 45.6%; p = 0.002) and 1/3 ball possession (55.3% vs. 44.7%; p = 0.018) was higher in T30 condition when compared to T45. Regarding match external load, total distance covered (4,899 vs. 4,481 m; p = <.001; ES = 0.71), moderate-speed running (607 vs. 557 m; p = 0.002; ES = 0.26) and high-speed running (202 vs. 170 m; p = <.001; ES = 0.33), high-speed activities (284 vs. 245 m; p = 0.003; ES = 0.24), accelerations (27 vs. 24; p = <.001; ES = 0.32), and decelerations (31 vs. 28; p = 0.005; ES = 0.26) were higher in T30 compared to T45. In conclusion, these findings suggest that higher effective playing time may affect technical-tactical and physical parameters during football games.

“…Despite the undoubted benefits of wearables, there are well-founded concerns regarding their implementation including: (1) limited evidence quantifying the potential beneficial effects of analysing specific parameters, (2) the quality of hardware and provided data, (3) information overload, (4) data security and (5) exaggerated marketing claims [11][12][13]. These concerns will be highlighted with particular focus on the two major sporting events reviewed, and by highlighting these concerns, we suggest that wearable devices that use biological data for sport performance undergo rigorous evaluation ensuring that these devices have received a certification of veracity [1,2] or guiding reference [14] prior to acceptance of use in elite sporting competition. This quality control process would undoubtedly be highly sought after by those individuals using them for general health monitoring.…”

“…The incorporation of recent technology that aims to enhance performance, athlete safety or the overall fan experience has become a vital part of elite sport. Examples include the use of video assistant referees in football [1], advanced analysis of pitcher performance on return from injury in baseball [2] and foot-worn inertial sensors providing better understanding of running economy during distance running [3]. The rapid development of these technologies in the context of elite sport means that the guardrails associated with the rules and regulations put in place to ensure safety, fair play and the integrity of competition must be updated based on science to prevent any one team or individual from gaining an unfair advantage and to maintain a level playing field.…”

A growing number of companies are developing or using wearable sensor technologies that can monitor, analyse and transmit data from humans in real time that can be used by the sporting, biomedical and media industries. To explore this phenomenon, we describe and review two high-profile sporting events where innovations in wearable technologies were trialled: the Tokyo 2020 Summer Olympic Games (Tokyo 2020, Japan) and the 2022 adidas Road to Records (Germany). These two major sporting events were the first time academic and industry partners came together to implement real-time wearable solutions during major competition, to protect the health of athletes competing in hot and humid environments, as well as to better understand how these metrics can be used moving forwards. Despite the undoubted benefits of such wearables, there are well-founded concerns regarding their use including: (1) limited evidence quantifying the potential beneficial effects of analysing specific parameters, (2) the quality of hardware and provided data, (3) information overload, (4) data security and (5) exaggerated marketing claims. Employment and sporting rules and regulations also need to evolve to facilitate the use of wearable devices. There is also the potential to obtain real-time data that will oblige medical personnel to make crucial decisions around whether their athletes should continue competing or withdraw for health reasons. To protect athletes, the urgent need is to overcome these ethical/data protection concerns and develop wearable technologies that are backed by quality science. The fields of sport and exercise science and medicine provide an excellent platform to understand the impact of wearable sensors on performance, wellness, health, and disease.

Introduction. The integration of modern technologies is crucial for enhancing elite athlete training, offering cutting-edge tools for performance optimization. The widespread use of technology in elite sports, including video assistant referees and wearable sensors, providing real-time biomechanical oversight, challenges related to ethics, data protection, and regulatory frameworks require resolution for widespread implementation. This study aims to conduct a thorough assessment of the integration of modern technologies, specifically examining their efficacy in optimizing the training performance and competitive outcomes of elite athletes in sports games. Material and Methods. Bibliometric techniques and expert evaluations were used to determine the modern trends in innovative technologies to improve the effectiveness of elite athletes` preparation. A thorough biomechanical analysis utilizing diverse methods was performed on 41 elite athletes in sports games. Results. The examination of sports science literature and expert assessments unveils predominant trends in the utilization of innovative technologies in elite sports, with a particular emphasis on the widespread adoption of wearable technology, biomechanics and motion analysis, and recovery and regeneration techniques. The outcomes from OpenCap biomechanical analysis show a high correlation (r=0.99, α = 0.05) between the symmetry of knee joint angles during barbell squats by elite athletes, confirming the efficacy of real-time monitoring exercise techniques. The Romberg coefficient of 194.5% ± 2.47 indicates a notable degree of stability among elite athletes. Conclusions. This study enhances the comprehension of innovative technologies, exemplified by OpenCap biomechanical analysis, and their effectiveness in optimizing the training performance and competitive outcomes of elite athletes in sports games. The findings provide valuable insights for coaches, sports scientists, and researchers aiming to optimize training methods and elevate athlete performance in sports games.
