Serena Williams is absent from this year’s Miami Open. But when you take a close look at many of the current contenders for the women’s title, you’ll see a significant new sign of her impact on the way matches can be won.
The move to a 17-game schedule has been expected since March last year, when the players agreed to an expanded regular season as part of their new collective bargaining agreement (CBA) with the league.
As well as increasing the regular season slate, Tuesday’s decision also means that the preseason schedule will be reduced from four games to three.
It marks the first change to the NFL’s regular season structure since 1978, when the league increased the number of fixtures from 14 to the current 16-game schedule.
We quantified on pitch external loading of English Premier League (EPL) academy soccer players (n=76; U12-U18 age groups) over an entire competitive season. Mean accumulative weekly duration and total distance, respectively, was similar in the U12 (329±29 min; 19.9±2.2 km), U13 (323±29 min; 20.0±2.0 km) and U14 (339±25 min; 21.7±2.0 km; P>0.05 for all comparisons) age-groups, though all teams were less than U15 (421±15 min; 26.2±2.1 km), U16 (427±20 min; 25.9±2.5 km) and U18 (398±30 min; 26.1±2.6 km) players (P<0.05 for all comparisons). Mean weekly high-speed running and sprint distance was not different between U12 (220±95 m and 6±9 m respectively), U13 (331±212 m and 6±27 m) and U14 (448±193 m and 21±29 m) age-groups (P>0.05 for all pairwise comparisons) though all squads were less than U15 (657±242 m and 49±98 m), U16 (749±152 m and 95±55 m) and U18 (979±254 m and 123±56 m) age-groups (P<0.05 for all pairwise comparisons). Data demonstrate that absolute weekly training volume in EPL academy soccer players increases throughout the academy pathway. Furthermore, although U16-U18 players are capable of achieving similar training and match volumes as previously reported in adult EPL players, they do not yet achieve the absolute intensities of adult EPL players.
Understanding fatigue after playing a football game and the recovery profiles of biological systems are two key elements to improve training programmes and reduce players’ injuries. The number of official matches that professional players play each season has significantly increased in the last few years. Apart from the regular league matches, the top teams have to play European competitions, other local championships, or international games with their corresponding national teams. If in the 1970s the number of games that the European Cup Champion team played reached 40, in the last few years, this number has gone up to 70 matches. For example, in the season 2018/2019, F.C. Barcelona played 60 official games, meaning a game each 4.5 days; taking into account that on several occasions, two games are played in 3 days. Trips and training sessions should also be included: as more than 250 annual training sessions can be done. Game overload is a threat to team performance.
Are 72 hours between two games enough for recovery? Should there be more resting periods? A recent publication has analysed the effect on fatigue while playing a football game, and how the players’ recovery evolves in different physiological, neuromuscular, technical, and biomechanical parameters and perceptive responses.3 To do so, they studied acute and residual fatigue for five different moments: during rest, during a match, and after the game during the next 24, 48 and 72 hours. Conclusions are based on the revision of 77 research articles that should meet the following criteria: to be published in English, longitudinal studies in regard to football players, the duration of the match should be longer than 45 minutes and the data collection protocol should be validated.
The Sioux Falls Skyforce, and the NBA G League as a whole, exist as a pathway for young players to eventually achieve their dream of playing in the NBA. From basketball operations executives and coaches to front office staff, everyone in the organization is doing their best to support these players in any way they can. Few, however, are asked to do more than Skyforce Athletic Trainer Ian Lackey.
Damian Roden comes to Minnesota United a new man for a newly created position — senior director of sports science — that oversees the club’s athletic training and medical departments.
He also comes with a long résumé in an arms race growing across Major League Soccer and globally a résumé that includes almost as many job titles as stops along the way.
“I’ve been called many things,” he said. “I’ve been called head of performance, director of performance, head of sports science, director of high performance. I think it just means that I’m old.”
At 46, he returns to MLS after two seasons back home in Wales and in Europe. He has worked for some of the biggest clubs in England and Europe, including the Premier League’s Manchester City and Belgium’s RSC Anderlecht. He was mentored by one of England’s great innovators, former Bolton Wanderers manager Sam Allardyce.

Rome wasn’t built in a day, and neither will Shannon Turley’s strength and conditioning program in Boulder. Turley was named CU’s director of football sports performance in late January, after previously enjoying a successful 12-plus year stint at Stanford.
Turley has been working with the Buffaloes’ football players for roughly two months now.
“I believe in simplicity and execution, and I’m trying to meet the players where they are right now, and prepare them for spring as our first task, and it’s something that will take time,” Turley said during a Zoom call with local media on Thursday. “It’ll take years. It doesn’t happen quickly. But thankfully, from my experience at Stanford, I learned a great deal about how to teach that process, and how to implement that in the most efficient way possible.
“It has been unclear whether the integration of this meaning is represented in a particular site in the brain, such as the anterior temporal lobes, or reflects a more network level operation that engages multiple brain regions,” says Andrew Anderson, research assistant professor in the University of Rochester Del Monte Institute for Neuroscience and lead author of of the study in the Journal of Neuroscience.
“The meaning of a sentence is more than the sum of its parts. Take a very simple example—’the car ran over the cat’ and ‘the cat ran over the car’—each sentence has exactly the same words, but those words have a totally different meaning when reordered.”
The study is an example of how the application of artificial neural networks, or AI, are enabling researchers to unlock the extremely complex signaling in the brain that underlies functions such as processing language.
To cate for the rapid development of flexible, wearable and implantable microelectronics, the miniaturized and integrated energy storage devices with mechanically robust properties, high voltage, and highly compatible integration are in extreme demand. Here, potassium ion micro‐supercapacitors (KIMSCs) are rationally designed by applying MXene‐derived potassium titanate (KTO) nanorods anode and porous activated graphene (AG) cathode to power the sensitively integrated pressure sensing system. Benefiting from the advanced nanostructure of KTO nanorods, it offers a high potassium ion storage capacity of 145 mAh g−1. Notably, the constructed KIMSCs exhibit a large operating voltage window of 3.8 V, outperforming the previously reported micro‐supercapacitors. Furthermore, an extraordinary volumetric energy density of 34.1 mWh cm−3 is achieved for KIMSCs with robust rate capability and remarkable capacitance retention, due to the dominated capacitive mechanism and tiny volume change of reversible intercalation/deintercalation of K cations in KTO and adsorption/desorption of bis(trifluoromethanesulfonyl) imide anions on AG. More importantly, a KIMSC compatibly integrated with a wireless pressure sensor on a flexible substrate can monitor body movement. Therefore, this work not only provides insight on designing high‐performance KIMSCs, but also presents a blueprint for KIMSCs powered flexible electronics.
Effective Jan. 1 of this year, all lacrosse goalies must wear chest protectors that meet the NOCSAE performance standard ND200. That goes for youth (US Lacrosse), high school (NFHS) and college (NCAA) and all disciplines of the game (men and women) played in the U.S. Come 2022, the mandate will extend to all field players in youth and high school boys’ and college men’s lacrosse.
US Lacrosse helped fund the research that led to the standard, which protects against commotio cordis, the rare but catastrophic phenomenon that occurs when a blunt blow to the chest wall directly over the heart happens during a precise moment in the heart’s cycle, disrupting the heart’s normal rhythm and causing cardiac arrest. NOCSAE approved the ND200 standard in January 2017.
The Football Association has started the process of replacing Head of Performance Insights Kate Baker, who left the organisation in February to join UK Sport.
However, the advertised role has the new title of Head of Player Recruitment (Men’s), even though many of the responsibilities are the same as those Baker had.
The Buffalo Sabres are 0-15-3 since Feb. 25. They own the record for the longest winless streak of the shootout era (since 2005-06) and have tied the 2003-04 Pittsburgh Penguins for the most consecutive losses — including overtime and shootout losses — in the 21st century.
How did they get here and how worse could it get? Plus, how do they get back on track — and could a Jack Eichel trade be forthcoming at some point down the road?
… Before 2006, evaluating quarterback prospects was mainly limited to game film, combine performance, and miscellaneous events such as pre-draft interviews. But by finding that college completion percentage and games started were predictors of NFL success, David Lewin changed that paradigm with the Lewin Career Forecast (LCF). In 2011, Aaron Schatz released the LCF v2.0, and in 2015, Andrew Healy took quarterback projections to the next level with QBASE (Quarterback Adjusted Stats and Experience). QBASE established a new way to evaluate a quarterback’s college statistics by adjusting them for the quality of his teammates and opponents. For instance, elite pass-catchers can artificially inflate a quarterback’s numbers, but facing SEC defenses can deflate them. Soon thereafter, the Cleveland Browns hired Healy for their front office, and Schatz continued the model.
Meanwhile, Jeremy Rosen and Alexandre Olbrecht built a separate model in 2018 that was the first to quantify the value of functionally mobile quarterbacks. Since then, Football Outsiders has run both models separately, but now in 2021, we are unveiling QBASE v2.0, which merges QBASE with the functional mobility model, combining the best ingredients of both.
