Does Derrick Rose still want to play in the NBA?

USA Today Sports, Jeff Zillgitt from

… When I saw Rose in Washington in early November, the night LeBron James scored 57 points, I told him he was shooting 72% on shots at the rim, and he said he needed to get that to 75%.

He didn’t sound like a player who was ready to contemplate his future with the Cavs and the NBA. But ESPN on Friday reported that Rose, who is out with a sprained left ankle, is not with the team and “is seriously re-evaluating his future in the NBA.”

 

Aaron Mooy: a modern success story for Huddersfield – and Manchester City

The Guardian, Paul Doyle from

The midfielder’s route to the top with Huddersfield, via Manchester City’s burgeoning global empire, illustrates not just the Australian’s talent but the new nature of player recruitment

 

Gregg Popovich of San Antonio Spurs says he’s ‘never’ encountered issue like Kawhi Leonard’s quadriceps injury

ESPN NBA, Michael C. Wright from

In a storied career spanning more than 40 years at various levels, San Antonio Spurs coach Gregg Popovich said he has “never” encountered the quadriceps issue that has kept Kawhi Leonard out of the lineup this entire season.

“Never, never,” Popovich said when asked whether he has seen such a condition hampering one of his players. “What’s really strange is that [point guard] Tony [Parker] has the same injury, but even worse. They had to go operate on his quad tendon and put it back together or whatever they did to it. So to have two guys, that’s pretty incredible. I had never seen it before those guys.”

 

David Wagner’s methods are paying off for Huddersfield Town in the Premier League

Sky Sports, Nick Wright from

David Wagner has transformed Huddersfield Town on a tiny budget, but how? From team-bonding trips in the Swedish wilderness to an obsessive attention to detail, Nick Wright gets the inside track on the methods which have made him one of the hottest coaching properties around.

 

Performance, not results: How Spurs and QPR develop young players

ESPN UK, Iain Macintosh from

Chris Ramsey points at the cracked screen of his touch-pad where two pyramids represent the priorities of the first team and the development team. The first team’s pyramid is pointed side down. At the bottom, the least important aspect of the first team is the individual. In the middle is the team performance and at the top, the widest segment of all, is the result. The development pyramid is inverted. Here the result is the least important aspect, then the team performance and then, broadest of all, is the individual. And on this notion rests the crux of Ramsey’s philosophy.

Now Technical Director at Queens Park Rangers, Ramsey arrived at Tottenham in 2005, working under John McDermott on a newly inaugurated 12-year plan of technique-focused youth development. That plan has now reached completion in spectacular style: Harry Kane is one of Europe’s hottest strikers, Danny Rose has become one of the nation’s finest left-backs and Harry Winks has broken into the England side alongside former Spurs youngster Jake Livermore. A host of fresh names await in the wings: Kyle Walker-Peters, Josh Onomah, Cameron Carter-Vickers and perhaps the jewel in the crown, the exciting Marcus Edwards.

 

Acute:Chronic Workload Ratio

Science for Sport, Ryan White from

Monitoring of training- and match-loads is imperative to enhance performance and prevent injury. An effective monitoring protocol can provide important feedback to assist in the planning and periodisation of training, optimise physical condition, and avoid injury. One such method which can provide this important ‘snapshot’ is the acute: chronic workload ratio. The acute:chronic workload ratio is comprised of an athlete’s ‘fitness’ and ‘fatigue’, and can be calculated using either the rolling average (RA) model or the exponentially weighted moving average (EWMA) model. The actual value presented by the acute: chronic workload ratio has different implications, and can assist practitioners in understanding the preparedness of an athlete, the relative injury risk of an athlete from day-to-day, and therefore, with carefully planned intervention, can help to prevent injury.

 

History of resilience should serve Penguins well

Pittsburgh Post-Gazette, Jason Mackey from

Penguins coach Mike Sullivan has been in the NHL in some capacity, either as a player or coach, since before many of his players were born. In every season, at least two things have happened — struggles and adversity.

“I’ve yet to be through a season where that doesn’t occur,” Sullivan said Thursday after a short, upbeat practice at UPMC Lemieux Sports Complex in Cranberry.

Sullivan’s current group is no different. They’re experiencing a few struggles and trying to overcome some adversity, and the good news is there’s a recent template on which to rely.

 

6 good triathlon training habits to develop

220Triathlon, Joe Beer from

… HABIT 1 THE 3:1 RATIO

Your body is a cyclical beast, and works in approximately four-week blocks. So if you plan your training accordingly – building consistent training ‘blocks’ and adaptation ‘down-times’ into your training plan – you’ll almost certainly get the best out of yourself.

This 3:1 plan makes you think ahead, and makes sure you adapt by reducing volume in the fourth week. It’s not hard to do. On the adaptation week, use the extra time gained from training less for body work, admin and seeing friends and family.

 

How Spurs, Man Utd and Juventus use ‘most powerful wearable in sport’

Training Ground Guru, Simon Austin from

When Jesus Perez looks at his smartwatch during a Tottenham training session, he’s unlikely to be checking how long it is until the canteen opens.

The Spurs fitness guru and his staff use watches to track up to 50 live player metrics – such as high-intensity sprints, fatigue and metabolic power – during both training and matches, using the APEX system developed by Irish tech firm STATSports.

Along with Manchester United, Arsenal, Monaco, Juventus and Athletic Bilbao (to name a few), Spurs are clients of the cutting-edge Newry-based firm.

APEX is STATSports’ third generation GPS system and was launched this summer. It is described as “the most powerful wearable in sport” and Richard Byrne, Head of Business Development for the firm, told TGG: “This is the most advanced athletic performance device ever released.”

 

Turn your clothes into health trackers

Yanko Design, Jack O'Farrell from

It seems like only yesterday the hype of fitness wearables was the talk of the town. It wasn’t long until that hype died down and we were left with this sense of confusion with what to do with our impulsively bought not-so-smart, smart wearables. Thankfully, with the passing of time and the history of lessons learned, comes a powerful new biosensor.

Introducing Spire Health Tag – the World’s smallest personal health microsensor that adheres to your clothes, no charging or changing required. No need to replace or recharge this wearable, Spire Health Tags have a year-long battery life and can go through the washer and dryer without having to be replaced or reapplied. The Spire Health Tag is the industry’s most miniature biosensor that discreetly adheres to your clothes and uses advanced algorithms to provide personalized, real-time health guidance for sleep, calmness and daily activity.

 

Sports Engineering Methods for Sports Science: Wearable Sensors and Machine Learning – Sponsored by Adidas

YouTube, ECSS .tv, Friedrich-Alexander-Universität Erlangen-Nürnberg from

Wearable computing systems play an increasingly important role in recreational and elite sports. They comprise of two parts. First, sensors for physiological (ECG, EMG, …) and biomechanical (accelerometer, gyroscope, …) data recording are embedded into clothes and equipment. Second, embedded microprocessors (e.g. in smartphones) are used for monitoring and analysis of the recorded data. Together, these systems can provide real-time information and feedback for scientific studies in real sports situations. Data mining concepts provide tools for analyzing the considerable amount of physiological and biomechanical data that is generated in sports science studies. Especially when using wearable computing systems, the number of participants and variety of measured data is unlimited in general. Traditional statistical analysis methods commonly cannot handle this amount of data easily. Thus, the analysis is often restricted to individual variables rather than multidimensional dependencies and a considerable amount of information is neglected.

 

Are athletic children more likely to develop arthritis younger?

AJC.com, Atlanta Journal Constitution, Jason Lemon from

As children increasingly participate in organized sports, doctors have begun seeing increased incidence of knee injuries among this population, raising concerns that youth athletes might be facing early arthritis.

“Yes, the numbers are up,” Dr. John Xerogeanes, professor of orthopedic surgery and chief of sports medicine at Emory University, told the Atlanta Journal-Constitution.

Xerogeanes suggests this may be due to a combination of factors.

 

Watford suffer most injuries in 2017/18

Training Ground Guru, Simon Austin from

Southampton have lost the lowest number of days to injury so far this season, while Watford have experienced the most.

The research was done by the respected Premier Injuries website, run by Ben Dinnery. Southampton have lost only 143 days to injury, while the Hornets, who are six places higher than them in the Premier League, have lost 513 – more than 3.5 times as many.

West Brom, who suffered the lowest number of significant injuries and days lost to injury last season, are in third place, with Liverpool second.

 

Measuring sports teams subreddits’ toxicity during losses (or: Sixers fans are not okay)

Medium, Tomer Kremerman from

Google’s Perspective algorithm assigns a toxicity score between 0–1 to short texts. It took some justified fire for assigning high toxicity scores to some particularly triggering false positives, but is still an interesting tool to gauge virulent language. Looking to try it out, I thought to run some experiments in an arena known for raw emotional responses — sports, or in particular sport fans after tough losses. And no franchise offers a more potent combination of savage, rancorous fans and prolonged misery than the Philadelphia 76ers.

Just this past Saturday, the newly rejuvenated Sixers gave up a 22-point half-time lead to lose to the Warriors 124–116. Their subreddit’s game thread had 1,439 comments, which seemed enough for a robust analysis. Now, Perspective’s toxicity scores are noisy in a high-adrenaline context, since “fuck yes!” is just as toxic as “fuck no!” (0.94). Still, I expected the level of toxicity to be lower during the first half, gradually go up as GSW got back in the game, and spike when the lead was overturned or after the final whistle.

Indeed, preliminary analysis (after scraping the thread and running all comments through Perspective’s API, regretfully deleting comments such as “Zaza pacheapshot” which the algorithm mistakenly identified as written in Finnish) seemed to match the hypothesis, with a substantial spike towards the end of the game.

 

The Big Six and … Burnley? A Success Story Confounds the Statisticians

The New York Times, Rory Smith from

Sitting in the board room at Burnley Football Club a couple of weeks before the start of the Premier League season, Mike Garlick, the team’s chairman, had only one cloud on his horizon.

The summer had been a good one. In May, Burnley had retained its place in the Premier League, finishing 16th but comfortably above the relegation zone. When Sean Dyche, the team’s manager, and his players returned for preseason training in July, they took up residence in a sparkling new training facility, a physical manifestation of the club’s blossoming self-belief.

Now Burnley could focus on how to cement its place among English soccer’s elite. The key, Garlick said, would be to start to replicate the team’s home form in away games. The previous year, Burnley’s stadium — the atmospheric, unreconstructed Turf Moor — had been something of a fortress. Dyche’s team had won 10 games at home. On the road, though, Burnley had struggled, winning only one and losing 14.

Garlick, like Dyche, had identified improving that record as a priority. And then, in the middle of June, this season’s league schedule was published. “Our first five away games are Chelsea, Tottenham, Liverpool, Everton and Manchester City,” Garlick said that day in July. It felt, if anything, a little cruel.
