Why Nashville Was Appealing Both on and Off the Ice for Matt Duchene

SI.com, NHL, Alex Prewitt from

… Plenty other teams courted his services in free agency—chiefly his favorite childhood squad, the Canadiens—but Duchene wound up where many figured he would all along. After all, here is a guy who succinctly describes himself like this: “Outside of my faith and my family, my three things in life are hockey, fishing and country music.” It made too much head-slapping sense for him to sign anywhere else.

“On the personal side, Nashville is just us,” Duchene told SI.com earlier this month at the NHL/NHLPA player media tour. “That’s who I am, that’s who my wife is, that’s what our families both are … When it came down to it, our hearts were definitely in Nashville.”

 

Why experts think Bianca Andreescu could dominate women’s tennis

CBC Sports, Myles Dichter from

… Andreescu’s mental game, according to all three experts, is a vital component in her success. The ability to focus just on the court is what allowed a 19-year-old to go 8-0 against top-10 opponents this season, including Andreescu’s crowning victory against Serena Williams in the U.S. Open final.

But all the strokes still need to be there, and from a technical perspective, Shriver, LaBelle and Bettauer struggled to come up with a weakness in Andreescu’s game. They agreed that her variety of strengths is what sets her apart from other women – and could even change women’s tennis for good.

‘I’ve just gotta get right.’ Panthers QB Cam Newton confirms Lisfranc in newest vlog Read more here: https://www.charlotteobserver.com/sports/nfl/carolina-panthers/article235565007.html#storylink=cpy

Charlotte Observer, Brendon Marks from

… Newton, smoking a cigar and sipping a glass of wine, confirmed that his mid-left foot sprain is actually a “mild” Lisfranc injury. The Athletic’s Joe Person first reported last week that Newton’s foot sprain was a Lisfranc.

Newton said that he was focused strictly on his shoulder coming into the 2019 season, until the team went to New England for Week 3 of the preseason.

“It happened — the unthinkable, so to speak,” Newton said. “Something else got hurt.”

 

Geno Auriemma on Katie Lou Samuelson: ‘Where Lou is right now is probably not as important as where she can go’

Chicago Sun Times, Madeline Kenney from

… ”I’m not surprised by either Lou or ‘Pheesa,” said Auriemma, who keeps tabs on his former players in the WNBA. “That the transition is going to be much more difficult for Lou than Pheesa, no doubt about it.”

Why?

In Auriemma’s eyes, it’s a matter of circumstance.

Samuelson was playing behind starters Allie Quigley and Diamond DeShields. On the bench, she was also competing with veteran forwards Kahleah Copper and Cheyenne Parker for playing time.

 

USMNT planning January training camp in Qatar: sources

Yahoo Sports, Doug McIntyre from

The United States men’s national team is planning to hold its next January training camp in Qatar, the host nation for the the 2022 FIFA World Cup, multiple sources told Yahoo Sports.

No agreement has been finalized, but U.S. coach Gregg Berhalter traveled to the middle eastern country after this month’s friendly matches against Mexico and Uruguay, a U.S. Soccer spokesman confirmed.

Eric Smith and Michael Grange talk about the Toronto Raptors starting training camp with some load management and Chris Boucher needing to prove himself.

 

Cardiac drift: what is it and how does it affect heart-rate training?

220 Triathlon, Alan Couzens from

During extended exercise, your heart rate is likely to rise even when the mechanical output (power or pace) stays the same. You may be running a flat course at a steady 5min/k and start the workout at 135bpm, but by the end of the workout your heart rate is 150bpm. This phenomenon is called ‘cardiac drift’.While it’s not fully understood, two factors seem to be at play.

 

THE RELATIONSHIP BETWEEN THE H:Q RATIO AND HAMSTRING INJURIES

Barca Innovation Hub from

Injuries are one of the main concerns in the world of sports as they are the primary reason which interrupts an athlete’s training program. Furthermore, when it comes to team sports, not only does it affect the player, but it also affects the whole team, from a tactical standpoint. Muscle injuries are the most common sports-related injuries, with hamstring injuries being the main cause in sports that involve running, a constant change in pace or abrupt leg decelerations such as the kicks that occur in football. One of the major issues with hamstring injuries, apart from their high incidence level, is the high rate of injury recurrence: around 13% of players suffer a recurrence in the first week after returning to their training, and around 8% have a recurrence in the second week (Seward & Orchard, 2004).

There are some risk factors for hamstring injuries that are non-modifiable, such as age, race or prior history of similar types of injury. Other risk factors are modifiable, such as a lack of strength and flexibility, fatigue or strength imbalance between agonist and antagonist muscles (de Hoyo et al., 2013). In the latter case, while there seems to be some level of controversy about the relationship between isolated hamstring muscle strength assessments and injury risk, scientific evidence leaves little doubt that there is an association between agonist muscles that are imbalanced with their antagonist (quadriceps muscles) and injury incidence.

 

Replacing “Learning Styles” with “Attention Types”

Doug Lemov, Teach Like a Champion blog from

I’ve been thinking a lot about the persistence of people’s belief in learning styles lately. Everywhere I go, teachers and coaches talk about the idea as if was established fact when in reality it is an idea without scientific basis.

Recently, I started asking myself Why is the myth so persistent when a little bit of reading should debunk it? Why does it appear to be so intuitively obvious that people don’t even think to question it? It must resonate with people for a logical reason. Such wide-spread allegiance to a flawed idea can’t be random.

 

Research Team Introduces ‘Phyjama,’ a Physiological Sensing Pajama, at International Wearable Technologies Conference

University of Massachusetts Amherst, News & Media Relations from

Scientists expect that in the future, electronically active garments containing unobtrusive, portable devices for monitoring heart rate and respiratory rhythm during sleep, for example, will prove clinically useful in health care. Now researchers at the University of Massachusetts Amherst have developed physiological-sensing textiles that can be woven or stitched into sleep garments they have dubbed “phyjamas.”

Graduate students Ali Kiaghadi and S. Zohreh Homayounfar, with their professors Trisha L. Andrew, a materials chemist, and computer scientist Deepak Ganesan, will introduce their health-monitoring sleepwear at the Ubicomp 2019 conference this week in London, U.K.

 

Sources: NU to unveil $150 million football facility plan Friday

Lincoln Journal Star (NE), Parker Gabriel from

Nebraska intends to build a new training facility that will jump NU to the cutting edge of a national arms race, multiple sources tell the Journal Star. The project is expected to come with a price tag in the neighborhood of $150 million.

NU on Thursday afternoon set a 1:30 p.m. Friday news conference on the East Stadium plaza, “to make a major announcement about the future of Nebraska Athletics.”

 

Prebiotics and probiotics’ effect on athletic performance

Science for Sport, Dr. James Morehen from

… This article explains how the collection of microorganisms in our digestive systems (known as the microbiota) contribute to a large variety of functions in our body. These functions include things such as inflammation, homeostasis, and the synthesis of neurotransmitters, such as dopamine, GABA, and serotonin, which are crucial in neuromuscular control.

Furthermore, the authors present evidence for the effect of various probiotic interventions on the incidence of gastrointestinal (GI) and respiratory pathology, including how probiotic supplementation may aid in both athletic performance and recovery.

 

On the menu for the Bruins: baby bok choy, turnips, and spaghetti squash

The Boston Globe, Matt Porter from

The habits of today’s NHLers are alien to their predecessors. Old-time players reached for a smoke between periods and beers after a win. Water breaks at practice were rewards, not required. The league was running on steak and potatoes.

“I don’t remember diet being a consideration at all,” said Rick Middleton, who retired as a Bruin in 1988.

 

The problem with metrics is a big problem for AI

fast.ai, Rachel Thomas from

Goodhart’s Law states that “When a measure becomes a target, it ceases to be a good measure.” At their heart, what most current AI approaches do is to optimize metrics. The practice of optimizing metrics is not new nor unique to AI, yet AI can be particularly efficient (even too efficient!) at doing so.

This is important to understand, because any risks of optimizing metrics are heightened by AI. While metrics can be useful in their proper place, there are harms when they are unthinkingly applied. Some of the scariest instances of algorithms run amok (such as Google’s algorithm contributing to radicalizing people into white supremacy, teachers being fired by an algorithm, or essay grading software that rewards sophisticated garbage) all result from over-emphasizing metrics. We have to understand this dynamic in order to understand the urgent risks we are facing due to misuse of AI.
