‘We don’t eat with cats’: How ‘Dawgwork’ has taken Los Angeles Rams’ D-line to greater heights

ESPN NFL, Lindsey Thiry from

Dawg — d-a-w-g — work: Either you’re gettin’ better or you ain’t.

No explanation needed if you’re a member of the Los Angeles Rams’ defensive line.

“It’s a mindset,” defensive tackle Aaron Donald said. “It’s a mentality.”

It’s grimy. It’s tough. It’s “whipping somebody’s behind, play in and play out, by working with great technique, fundamentals, energy and effort,” according to cornerback Jalen Ramsey, an honorary member of the pack.

It’s the ethos of second-year defensive line coach Eric Henderson, whose group sets the tone for a defense that ranks second in the NFL in efficiency, and dawgwork starts with how Henderson treats the league’s best defensive player.


For the Maple Leafs and many other elite athletes, lockdown doesn’t mean locked out

Toronto Star, Kevin McGran from

The Toronto Maple Leafs are still working out at the Ford Performance Centre.

The exemption created in the spring that allowed the Leafs to prepare for last summer’s expanded NHL playoffs remains in effect for many of Ontario’s professional teams, even with Toronto and Peel Region starting a 28-day lockdown to battle the deadly coronavirus pandemic.

“We continue to operate our training facility in accordance with a return to play plan approved by the Office of the Chief Medical Officer of Health,” Steve Keogh, the Leafs’ director of media relations, said by email. “We’ll of course look to stay in close contact with public health authorities at all levels of government and monitor developments closely.”


Andreatta intent on helping build a platform to strength Westfield Matildas

Matildas (Australia), Marissa Lordanic from

… “Through this camp, not only will training sessions occur and an internal game, but there’s also education workshops that are occurring in the evening with various staff members, and our senior national team players contributing.”

“One of the key objectives is to share with these players who haven’t been in the environment recently, or at all, an insight into what it’s like and what the standards are to be a Matilda, to stay as a Matilda and to thrive as a Matilda.”

With four major tournaments over the next four years, deepening the player pool to provide a platform for success is the objective.


‘Brutal intensity’ — The methods behind Bayern Munich’s fitness transformation

Squawka, Dr Rajpal Brar from

… many of Bayern’s players have undergone a quite drastic transformation in terms of their physiques, packing on the muscle while keeping extremely lean in the process.

These transformations look like something out of a Marvel movie (super serum, perhaps?) and are a testament to Bayern Munich’s health and fitness planning, from staff to players, and to their fitness team.

That fitness team is led by Dr Holger Broich, who has the title of “Chief Scientific officer and head of fitness”; a position he’s held at the club since January of 2014.

The title itself — with an emphasis on both ‘science’ and fitness — gives a key insight into Bayern Munich’s approach and how the fitness team condition their players for the gruelling intensity of a top-flight season in professional football.


Why Kendall Coyne Schofield hopes to break more barriers

NBC Sports, Charlie Roumeliotis from

Kendall Coyne Schofield has been breaking barriers her whole life. And she did it again on Monday when the Blackhawks made her the first female player development coach in franchise history.K

“This is an incredible opportunity,” Coyne Schofield said in a video conference call. “I’m so excited. I remember being three years old putting on my first pair of skates and watching the Blackhawks play, and at seven years old playing in the junior Blackhawks game at the United Center and doing it again when I was nine. And then from there time passed and I became the intern in 2014 after the Olympics in the media relations department.

AIS Brings Brightest Sport And Technology Minds Together For STARS

Australia Ministry of Sport, Joshua Hodson from

The Australian Institute of Sport (AIS) has revealed the third annual Sports technology and Applied Research Symposium (STARS), a two-week event starting Monday, November 23, 2020.

The symposium is set to bring together presentations from such people as Triathlon Australia’s Dr. Paula Charlton on preventative health, USA biomechanist Dr. Peter Vint on the use of deterministic modelling, and sleep expert, Professor Greg Roach.

AIS director, Ian Burns, said the presentations will cover anything ranging from the latest in artificial intelligence and data capturing, to better understanding injury and illness prevention, with two weeks to be filled with insights, research and innovation about the next big breakthroughs in sport and technology.

“There is so much we still don’t know about the human body and what we are capable of, so STARS provides a unique opportunity to showcase advancements being made across different industries, both locally and overseas,” Burns said.


Amazon’s Echo Buds get new fitness tracking features

TechCrunch from

I wasn’t super impressed when I reviewed the Echo Buds around this time last year, but Amazon’s first shot at Alexa-powered fully wireless earbuds was passable. And while they’ve already been on the market for a while now, the company’s continuing to deliver some key updates, including today’s addition of new fitness features.

Say “Alexa, start my workout” with the buds in, and they’ll begin logging steps, calories, distance, pace and duration of runs. Like many new software additions, this one will take a few days to roll out for everyone. This one also requires users to enable the new tracking feature using the Alexa app.


Validity and reliability of an eight antennae ultra-wideband local positioning system to measure performance in an indoor environment

Sports Biomechanics journa from

Validity and reliability have become crucial factors in tracking player load and positioning. One of the most important parameters to guarantee accurate measurements with radiofrequency systems is the number of reference nodes used to calculate player position. However, the accuracy of ultra-wideband (UWB) technology has only been analysed with 6 antennae. So, the purpose of the present study was to analyse the accuracy and inter-unit reliability of an UWB system with eight antennae. Three well-trained males covered 18 trajectories for the analysis of x- and y- coordinate accuracy assessment related to the positional variation among eight antennae UWB data and lines on a basketball court. This was achieved using geographical information system mapping software that calculated, for each interval and participant, the distance from the main axis of locomotion and the opposite side of the field every 0.5 s. The results showed that this is a valid system (Mean = 0.03 m; magnitude differences = 0.21% with real measures as reference; %CV <1% in all cases) for measuring locomotion and positioning. Besides, the inter-unit, test-retest and inter-subject analysis did not influence the reliability results. So, an eight antennae UWB system can be considered suitable for locomotion and positioning in an indoor environment.


AliveCor, which helps its users manage their heart health, scores another FDA approval

TechCrunch, Conie Loizos from

Last week, AliveCor, a nine-year-old, 92-person company whose small, personal electrocardiogram devices help users detect atrial fibrillation, bradycardia, and tachycardia from heart rate readings taken from their own kitchen tables, raised $65 million from investors.

Today, it’s clearer why investors — who’ve now provided the Mountain View, Ca., company with $169 million altogether — are excited about its prospects. AliveCor just received its newest FDA clearance under the agency’s software as a medical device designation for an upgrade that generates enough detail and fidelity that AliveCor says its cardiological services can now serve as stand-in for the vast majority of cases when cardiac patients are not in front of their doctor.


The COVID-19 pandemic: how to maintain a healthy immune system during the lockdown – a multidisciplinary approach with special focus on athletes

Biology of Sport journal from

On January 31, 2020, the World Health Organization (WHO) declared the outbreak of a novel coronavirus responsible for an infection termed COVID-19 as a global public health emergency. To slow the spread of the coronavirus, countries around the world have been implementing various measures, including school and institutional closures, lockdown and targeted quarantine for suspected infected individuals. More than a third of the world’s population have been home confined less than 4 months after the start of the outbreak. The present article aims to advise healthy individuals and athletes who are in lockdown regarding their lifestyle in order to keep healthy, safe and fit. The advice contained in the present article could apply to anyone aiming at remaining in good physical and mental health while forced to undergo lockdown, quarantine, or limited movement (movement control order). Boosting the immune system is crucial during such periods for confined people and especially for confined athletes. Specific recommendations must be followed concerning boosting the immune system through physiological and psychological management. This article analyses the available scientific evidence in order to recommend a practical approach, focusing on nutrition, intermittent fasting or caloric restriction, vitamin D insufficiency, sleep pattern, exercise, and psychodynamic aspects as factors impacting the immune system and human health in general.


Visualizing and Analyzing Disputed Areas in Soccer

VIS2020, Jules Allegre and Romain Vuillemot from

Space ownership models assign 2D areas to individuals, based on their ability to reach locations according to their direction and speed. In this paper, we investigate the case where two or more individuals can reach a given location simultaneously. We refer to those locations as disputed areas, as there is tension and uncertainty on ownership, which is an important spatial analysis tool, e. g., in sports where players share a space with adversaries. We present the process to calculate those disputed areas from existing space ownership models, and introduce several visualizations and analysis of those areas using sport tracking data from Liverpool 2019’s goals. Those areas have been particularly insightful to understand assists, the ultimate pass that is critical for a team to score. We also report on feedback from experts both on the relevance of those areas as well as their visual design.


Matt Crocker: Why Southampton have moved away from loans system

Training Ground Guru, Simon Austin from

Southampton Director of Football Operations Matt Crocker says the club have ‘moved away’ from the loans system and will rarely send young players to other clubs.

As TGG has outlined before, the loans system has become a major industry in its own right, with many clubs employing specialist loan managers to manage the process.

However, Crocker, who moved to Southampton from the Football Association at the end of last year, says the system has not worked for his club.

“If you look over the last 10 years, our statistics tell us, in the main, that the players come through our Academy, train with the first team, join the first-team squad and then play for the first team,” he told The Athletic.


Analyzing Defensive Pass Interference Fouls in the NFL and NCAA

NFL Football Operations from

Defensive pass interference (DPI) is one of the most impactful penalties in the NFL. With the way it is enforced, it is often suggested by fans and media alike that the rule should be modeled similarly to the NCAA. In the NFL, DPI is a spot foul, yielding an automatic first down to the team in possession. In NCAA football, the rule is slightly different — DPI is still a spot foul, but the maximum penalty is 15 yards.

How does DPI compare in the NFL and NCAA? NFL Football Operations breaks down three graphs that compare the two levels of football and provide further insights into the penalty.
