Tyler Adams: “I’m fit and ready to play.”

SBI Soccer, Larry Henry Jr. from

Tyler Adams signed a contract extension with Bundesliga side RB Leipzig on Sunday and now looks ready to take his place back in Julian Nagelsmann’s starting lineup.

In an interview with the club’s website, Adams reflected on his recovery from a pulled calf suffered earlier this year and his reason for extending his stay at the club.

“Suffering another injury setback was a bit frustrating,” Adams said. “I’m happy that it’s only been a couple of weeks and am excited to be back training with the team. I’m fit and ready to play!”

Pro Soccer USA, Glenn Crooks from

Josh Wolff was training and competing with 1860 Munich in the Bundesliga when his future after playing came into focus.

“I think when I went to Germany, the game was presented in a different way,” Wolff told Pro Soccer USA. “One of the first things I think that I felt was like, wow this was something different and something that I enjoyed seeing and hearing.”

Buffalo’s Ralph Krueger, Anaheim’s Dallas Eakins and Los Angeles’ Todd McLellan had no illusions about quick fixes in their first seasons. But in a league that has seen plenty of coaching changes the past couple seasons, all three have remained consistent in their message since training camp in September.

“We have not discussed in our room anything beyond what we can take care of today. We’ve done this since September and we’re going to continue to do it, so, really, those are big-picture discussions,” Krueger said.

When it comes to this season, the Sabres, Ducks and Kings will not make the playoffs. Los Angeles and Anaheim once again are in a battle for the bottom of the Western Conference, but have shown strides in implementing more up-tempo styles of play.

 

Can’t Afford A Personal Trainer? Artificial Intelligence Could Help

90.5 WESA, Kathleen J. Davis from

Personal training is a popular but expensive option in the $100 billion fitness industry; it can cost an average of $40-70/hour. Local startup Delta Trainer is using artificial intelligence to make personal training more accessible.

Everyone who signs up for Delta Trainer gets an Apple Watch and is connected with a remote personal trainer, who sets up a unique workout plan for each of their clients. But the trainer isn’t there in person to monitor someone’s squats and lunges; that’s the AI’s job. [audio, 1:30]

 

NFL adds Microsoft Teams platform to technology deal

SportsPro Media, Sam Carp from

The National Football League (NFL) has announced a multi-year extension and expansion of its partnership with technology giant Microsoft.

The new deal will see all 32 NFL franchises use the Microsoft Teams platform, a collaborative tool which brings together chat, calling, meetings, files and documents into a single app.

In addition, the new partnership ensures that players and coaches in the North American football league will continue to use Microsoft’s Surface tablets on the sidelines during games to analyse plays, while referees will still use the devices for video reviews.

Getting closer to no-battery devices

Network World, Patrick Nelson from

IoT sensors that don’t require power sources could be coming soon. Researchers from University of California, San Diego, claim they’ve figured out how to optimize lab-based modules to such an extent that a Wi-Fi radio, used in IoT for communications with a network, could soon be using 5,000-times less energy and yet still feature enough bandwidth to send video.

The technique being exploited takes advantage of backscattering. That’s a way of parasitically using radio signals inherent in everyday environments. In this case, the chip piggybacks on existing Wi-Fi transmissions to send its data. This method of sending data is power-light, because the carrier needed for the radio transmission is already created—it doesn’t need new energy for the message to be sent.

Interestingly, two principal scientists involved in this backscattering project, which was announced by UC San Diego’s Jacobs School of Engineering, have also been heavily involved in the development of “wake-up” radios.

 

JUANJO BRAU: “INJURIES AREN’T TREATED, THEY’RE MANAGED”

Barca Innovation Hub from

Juanjo Brau arrived at FC Barcelona in 1997 and now he is the head of the physiotherapy department at the club. He holds that there are no manuals to face elite sports demands. To manage injuries with short recovery periods due to competition demands, make scientific knowledge and the use of technology a must but it is also very important the rehabilitator’s intuition to interpret the situation. A combination, in his words, of art and science.

You’ve been in the profession for many years: What’s changed since you started?

A lot of things have changed. There’s much more knowledge, research and technology.

Nowadays what are the physiotherapist’s specific tasks?

For many reasons today they’re indispensable within a team. They’re a link between the player, the medical staff and the coach. The physiotherapist helps the player on a daily basis for his well-being, and I would dare to say that the physiotherapist is indispensable in a team.

 

How Is Orthorexia Treated? Experts Explain

Bustle, Jay Polish from

Wanting to do what’s best for your body is an extremely understandable impulse. Messages to eat whole foods and exercise are everywhere and are generally well intentioned. But in a world so marked by toxic diet culture, a desire to live a “healthy” life can quickly turn into a negative obsession. Experts now say this kind of obsession can actually be an eating disorder called orthorexia nervosa. As with other forms of disordered eating, treating orthorexia can require the help of a mental health professional and a solid support network.

“Orthorexia nervosa develops when healthy eating becomes an obsession or preoccupation that results in distress or anxiety over ‘breaking’ one’s self-imposed nutritional rules,” says Dr. Elizabeth Barchi, M.D., sports medicine specialist at the NYU Langone Center for Women’s Sports Health. “This rigid adherence to a specific diet, or restriction of certain foods, can lead to nutritional imbalances and other negative health effects.”

 

Guest Editorial: Understanding Pronation

Lower Extremity Review Magazine, Mark Mendeszoon from

As a podiatrist, athlete, coach, and independent running shoe proprietor, I have always had an interest in biomechanics and the impact on lower extremity overuse injuries and conditions. Perhaps the most well-known biomechanical term, pronation, is also the most misunderstood. In his recent article, Benno Nigg et al. (see Foot Pronation, pg 33-38)1 confirm that pronation is an integral part of the gait cycle and has a direct impact on lower extremity injuries. After a thorough review of previous studies, Nigg confirmed that pronation is appreciated by the profession but still a theory and not an absolute science. While that may be true academically for clinicians, the importance of recognizing biomechanics is imperative in treating patients. It can also play a role in building one’s practice.

 

Mental health and psychological well-being among professional rugby league players from the UK

BMJ Open Sport & Exercise Medicine journal from

Objective This study aimed to measure depressive symptoms, anxiety symptoms and psychological well-being among a sample of Super League players, the highest tier of professional rugby league in the northern hemisphere.

Methods Between November 2018 and July 2019, a sample of 233 Super League players completed questionnaires that assessed depressive symptoms, anxiety symptoms and psychological well-being.

Results Players exhibited normal (85.8%), mild (11.6%) or moderate/severe (2.6%) depressive symptoms. Additionally, players reported normal (67.4%), mild (18.9%) or moderate/severe (13.7%) anxiety symptoms. The mean psychological well-being score across the sample was 25.07 (SD=4.34). 35.2% of players scored below average for this construct.

Conclusion The prevalence of mild depressive symptoms, moderate/severe depressive symptoms and mild anxiety symptoms among Super League players preliminary appear higher than in the general population from the UK. Much more research is needed to understand mental health among elite athletes. [full text]

 

How much glucose from sports drinks can be used as fuel?

Nutrition Tactics blog, Jorn Trommelen from

… It appears there is a limitation in the absorption speed of glucose in the GI tract. When glucose is consumed at a rate of >1 g/min, it just seems to accumulate in the gut and make you feel sick.

In conclusion, a high glucose intake does not further increase the use of glucose as fuel during exercise as compared to a moderate intake (1 g/min). Therefore, it is better to avoid high glucose intakes during prolonged exercise, as these are not used as fuel and will probably result in gastro-intestinal complaints.

 

Why athletes shouldn’t be concerned about their BMI

Canadian Running Magazine, Madeleine Kelly from

… According to the above graph of professional athletes’ BMI scores, LeBron James, Kevin Durant and Odell Beckham Jr. are all approaching obese. However, sports nutritionist Jennifer Sygo says that this is common when it comes to body mass index and elite athletes, because the index isn’t geared towards assessing an athletic population. “Body mass index is a tool that can be used to assess risk of developing disease. It’s largely used to measure population health and asses individual risk of type two diabetes, cancer or heart failure. But these are issues that become less prevalent when looking at an athletic population.”

 

Wanted: Data Stewards: (Re-)Defining The Roles and Responsibilities of Data Stewards for an Age of Data Collaboration

Medium, Data & Policy; Stefaan G. Verhulst, Andrew Zahuranec, Andrew Young and Michelle Winowatan from

Not all data collaboratives are successful or go beyond pilots. Based on research and analysis of hundreds of data collaboratives, one factor seems to stand out as determinative of success above all others — whether there exist individuals or teams within data-holding organizations who are empowered to proactively initiate, facilitate and coordinate data collaboratives toward the public interest. We call these individuals and teams “data stewards.”

 

Data scientists in soccer need to grow a pair!

Soccer Analytics Newsletter, Richard Whittall from

… The problem, of course, is that your work as a data scientist won’t be as effective if it is primarily there to make someone else look good. For one, data science doesn’t work that way; the work of an analyst is to tilt the odds in your team’s favour, but there is a lot of random variation in football, and positive results tend to accrue over time and are not always obvious to those in power.

A much more ideal situation, therefore, is for analysts to have more autonomous and clearly delineated decision-making power within a team. Maybe the analyst has final say in developing recruitment short-lists for example, with the manager following through in collaboration with the DoF. Or perhaps the analyst has full authority in preventing players at risk of injury of starting.

This all might sound insane! Analysts are so used to grovelling to people in power, making suggestions, coming up with attractive data viz and hinting at what a manager may or may not do to win. But the reality is, analytics must move beyond begging for power to survive and to make a lasting influence.
