Q&A: Former Colorado star Derrick White on being coached by Gregg Popovich and Becky Hammon, Tony Parker’s departure

Denver Post, Gina Mizell from

At 6-foot-4 and 190 pounds, the former Colorado guard is not the most imposing presence on the floor. But White has spent much of his offseason in the weight room, preparing his body for his second season of matching up against the “grown men” of the NBA.

“I don’t really know how much (muscle I’ve gained),” White told The Denver Post on Sunday afternoon. “But I just feel a little bigger and feel stronger.”

And it’s showing on the court. Before pulling his hamstring in Sunday’s contest against Washington, White led San Antonio in scoring (22 points per game) and assists (6.5 per game) through its first four games of summer league play in Salt Lake City and Las Vegas.

White chatted with The Denver Post about a variety of topics, including his rookie season, being coached by Gregg Popovich and Becky Hammon and potentially earning more playing time following the departure of Tony Parker.

 

Swimmer Ryan Lochte suspended until July 2019 for use of IV

Associated Press, Tim Reynolds from

Ryan Lochte posted a photo for the world to see, and the U.S. Anti-Doping Agency noticed.

It got him suspended — again.

The longtime U.S. swimming star has been banned from competition until July 2019, which means the 12-time Olympic medalist cannot compete as planned in the national championships that start this week in California. Lochte will also be ineligible for other top meets, including the Pan Pacific Championships later this year and next year’s world championships.

“This is devastating,” Lochte said.

 

Texas Derby equalizer encapsulates Manotas’ progress with Houston Dynamo

MLSsoccer.com, Jesus Acevedo Jr. from

When Mauro Manotas joined the Houston Dynamo four years ago, he had a goal in mind: to leave a mark on the club.

Now, finally entrusted with a starting role after biding his time, the Colombian is blazing a trail up Houston’s all-time scoring list.

His 8th-minute strike against FC Dallas in 2018’s first Texas Derby match on Saturday was Manotas’ 34th goal across all competitions, which moves him into a tie for fourth with former Dynamo Giles Barnes on the club’s all-time scoring list across all competitions.

For comparison, it took Barnes 10,387 minutes to get his 34 goals. Manotas has done it in 5,398 minutes.

“I am very happy due to my achievements. I only speak on the field. When I came here four years ago, my mentality was to leave a mark, whether it be with title or goals,” Manotas said after the eventful 1-1 draw. “There are many that rate forwards with goals, since a forward that can’t score is not a forward.”

What to Do with Too Much Advice

Y Combinator, Aaron Harris from

… I’ve found, in working with startups, that good founders generally have a strong sense of what they want to do before asking questions. They are led astray when, in attempting to avoid a bad decision, they start asking many different people for confirmatory advice about an idea. At YC, we call this “shopping for advice,” and it usually ends with a long period of nothing happening, or with founders getting frustrated that no one is confirming what they want to do. The best thing a founder can do here is either a) listen to the first person and alter course or b) try the thing they want to do anyway and see how it goes.

Understanding this means accepting the fact that, in all likelihood, any decision that you make as a founder, no matter how well advised, will likely be at least a little, if not mostly wrong. This seems illogical because advisers are meant to know so many things, and we expect them to give good advice. However, no adviser can possibly understand the full context of your business, so, at best, they are able to offer general advice or frameworks for thinking through problems.

 

Single-sport kids feeling the strain of specialization, experts say

CBC News, Anna Wasserman from

In rinks across the country, children are spending their summers perfecting their hockey game. It’s an idea pushed by parents and coaches — if children want to reach an elite level, they need to dedicate themselves to one sport.

But research suggests early sports specialization — spending eight months or more a year playing a single sport — can do young athletes more physical harm than good.

 

Arizona State University studying effects of heat on athletic performance

ABC 15, Meg Thompson from

While being unprepared in the desert sun can be dangerous, at Arizona State University, researchers are using the sun to their athletes’ advantage.

“Performance improves as they become better acclimated with the heat,” explained Josh Beaumont, ASU Associate Athletic Trainer explained.

 

Nike’s lightning shoes hint at power of technology to skew elite competition

The Guardian, Sean Ingle from

Do you know the most remarkable thing about Nike’s £200 Vaporfly Elite trainers? They actually live up to the hype. When the shoe was launched last year, Nike insisted it improved running economy by an average of 4% – a claim so astounding that it caused many sports scientists’ eyebrows to rise in scepticism, loosely aping the company’s swoosh logo.

However last week, the New York Times, having analysed 495,000 marathon and half-marathon times since 2014 using data from Strava, reached a similar conclusion. Runners who wore Vaporflys, which have a controversial carbon-fibre plate in their soles, did indeed run 3-4% quicker on average than similar runners wearing other shoes, and around 1% faster than those using the next speediest shoe.

Your first instinct might be to rush out and buy a pair – especially as a separate study in the journal Sports Medicine on elite athletes estimated that the shoes could take six minutes off a three-hour marathoner’s time. Good luck with that. The shoes appear to be almost permanently sold out, and often go for double their retail price on eBay.

 

The Wearable Tech That Aims To Produce Better Running Technique

adigaskell, The Horizons Tracker from

Over the past few years I’ve covered a number of technologies that have aimed to move beyond merely recording our activity levels and towards providing constructive feedback in real-time. Some of these are helping with coaching support, such as instructing the user to work harder, whilst others provide technical feedback on form and technique.

Nowhere is such a requirement as urgent as with runners, as those with poor, heel-based technique suffer roughly twice as many injuries as those with robust, forefront techniques. New research from Saarland University wanted to see whether technology, and technology alone, could rectify matters.

“An effective analysis of running technique can only be provided by professionals or expert coaches using slow-motion videos. Amateur athletes have no access to this. However, as more and more people run long distances, exposing themselves to the risk of knee injuries and stress fractures, answering this question is more necessary than ever before,” the authors say.

The team developed a product, known as Footstriker, that is worn on the body and provides electro-stimulation (EMS) to the runner to provide live feedback regarding their technique.

 

Smartphone app helps college coaches prevent NCAA recruiting violations

Greenville News, Manie Robinson from

… [Robbie] Caldwell clings to the nostalgia of simpler times, but he knows his current position leaves little room for patient conversation. One cannot wait for the mail-carrier to deliver handwritten notes along the recruiting trail. It requires fast-paced, consistent communication. The mounds of messages mounts so high that coaches can lose tracks of all their comings and outgoings.

For ordinary citizens, that simply results in an awkward redundant call. For coaches, it can result in a minor NCAA infraction. Luckily, Caldwell and other converted communicators can trust technology to monitor their messages.

College athletic compliance programs utilize robust software programs to log and monitor recruiting activity. Coaches must log each of their calls, text messages and school visits through an application on their smartphone. The activity is reported directly to the compliance office, and any potential problems are flagged.

“This is the beauty of the age we’re in,” Clemson associate athletic director for compliance Elliott Charles said. “Their phone locks the activity once it occurs. They have to then provide an explanation. They can’t erase it. That’s a key piece to the monitoring efforts. It requires communication.”

 

Validation of electronic performance and tracking systems EPTS under field conditions

PLOS One; Daniel Linke, Martin Lames from

The purpose of this study was to assess the measurement accuracy of the most commonly used tracking technologies in professional team sports (i.e., semi-automatic multiple-camera video technology (VID), radar-based local positioning system (LPS), and global positioning system (GPS)). The position, speed, acceleration and distance measures of each technology were compared against simultaneously recorded measures of a reference system (VICON motion capture system) and quantified by means of the root mean square error RMSE. Fourteen male soccer players (age: 17.4±0.4 years, height: 178.6±4.2 cm, body mass: 70.2±6.2 kg) playing for the U19 Bundesliga team FC Augsburg participated in the study. The test battery comprised a sport-specific course, shuttle runs, and small sided games on an outdoor soccer field. The validity of fundamental spatiotemporal tracking data differed significantly between all tested technologies. In particular, LPS showed higher validity for measuring an athlete’s position (23±7 cm) than both VID (56±16 cm) and GPS (96±49 cm). Considering errors of instantaneous speed measures, GPS (0.28±0.07 m⋅s-1) and LPS (0.25±0.06 m⋅s-1) achieved significantly lower error values than VID (0.41±0.08 m⋅s-1). Equivalent accuracy differences were found for instant acceleration values (GPS: 0.67±0.21 m⋅s-2, LPS: 0.68±0.14 m⋅s-2, VID: 0.91±0.19 m⋅s-2). During small-sided games, lowest deviations from reference measures have been found in the total distance category, with errors ranging from 2.2% (GPS) to 2.7% (VID) and 4.0% (LPS). All technologies had in common that the magnitude of the error increased as the speed of the tracking object increased. Especially in performance indicators that might have a high impact on practical decisions, such as distance covered with high speed, we found >40% deviations from the reference system for each of the technologies. Overall, our results revealed significant between-system differences in the validity of tracking data, implying that any comparison of results using different tracking technologies should be done with caution.

 

The impact of tackle football injuries on the American healthcare system with a neurological focus

PLOS One; Michael J. McGinity, Ramesh Grandhi, Joel E. Michalek, Jesse S. Rodriguez, Aron M. Trevino, Ashley C. McGinity, Ali Seifi from

Background

Recent interest in the study of concussion and other neurological injuries has heightened awareness of the medical implications of American tackle football injuries amongst the public.
Objective

Using the National Emergency Department Sample (NEDS) and the National Inpatient Sample (NIS), the largest publicly available all-payer emergency department and inpatient healthcare databases in the United States, we sought to describe the impact of tackle football injuries on the American healthcare system by delineating injuries, specifically neurological in nature, suffered as a consequence of tackle football between 2010 and 2013.
Methods

The NEDS and NIS databases were queried to collect data on all patients presented to the emergency department (ED) and/or were admitted to hospitals with an ICD code for injuries related to American tackle football between the years 2010 and 2013. Subsequently those with football-related neurological injuries were abstracted using ICD codes for concussion, skull/face injury, intracranial injury, spine injury, and spinal cord injury (SCI). Patient demographics, length of hospital stay (LOS), cost and charge data, neurosurgical interventions, hospital type, and disposition were collected and analyzed.
Results

A total of 819,000 patients presented to EDs for evaluation of injuries secondary to American tackle football between 2010 and 2013, with 1.13% having injuries requiring inpatient admission (average length of stay 2.4 days). 80.4% of the ED visits were from the pediatric population. Of note, a statistically significant increase in the number of pediatric concussions over time was demonstrated (OR = 1.1, 95% CI 1.1 to 1.2). Patients were more likely to be admitted to trauma centers, teaching hospitals, the south or west regions, or with private insurance. There were 471 spinal cord injuries and 1,908 total spine injuries. Ten patients died during the study time period. The combined ED and inpatient charges were $1.35 billion.
Conclusion

Injuries related to tackle football are a frequent cause of emergency room visits, specifically in the pediatric population, but severe acute trauma requiring inpatient admission or operative interventions are rare. Continued investigation in the long-term health impact of football related concussion and other repetitive lower impact trauma is warranted.

 

The First Decade of Web-Based Sports Injury Surveillance (2004-2005 Through 2013-2014): Methods of the National Collegiate Athletic Association Inj… – PubMed – NCBI

Journal of Athletic Training from

OBJECTIVE:

  To describe the methods of the National Collegiate Athletic Association (NCAA) Injury Surveillance Program (ISP) and High School Reporting Information Online (HS RIO) system as a complement to the sport-specific manuscripts that will follow.
BACKGROUND:

  The NCAA-ISP and HS RIO collect injury and exposure data from samples of collegiate and high school sports programs, respectively. The NCAA-ISP, which the NCAA has maintained since 1982, was relaunched as a Web-based platform at the beginning of the 2004-2005 academic year. In 2005, the HS RIO was introduced to capture data on high school athletes and modeled after the NCAA-ISP. Relevant data are shared with the NCAA and high school sport and policy committees to develop evidence-based rules and programs that help protect the health and safety of student-athletes.
DESCRIPTION:

  The NCAA-ISP and HS RIO monitor participation in school-sanctioned competitions and practices that occur from the first preseason practice to the final postseason contest for more than 25 sports. For this series of publications in the Journal of Athletic Training, injury information on 13 sports at the collegiate level during the 2004-2005 through 2013-2014 academic years and the high school level during the 2005-2006 through 2013-2014 academic years was evaluated.
CONCLUSIONS:

  Athletic trainers have been a vital source of data collection over the past decade to help produce the largest datasets of high school and collegiate sports injuries. Such data have helped various sport and policy committees advance protocols that aim to increase sports safety. This series of publications will aid by continuing to provide data to stakeholders in the sports community.

 

Peter Vermes’ candidacy as U.S. men’s national team coach

The Kansas City Star, Sam McDowell from

… With its glaring absence from the 2018 World Cup officially an item of history, U.S. Soccer is expected to accelerate its search for a new men’s national team coach. Vermes previously met with a high-ranking official from the federation earlier this year, preliminary discussions centralized on both the general manager and coaching vacancies, he told The Star. U.S. Soccer since hired Philadelphia Union sporting director Earnie Stewart to fill its newly created general manger role, a job he will assume on Aug. 1.

The coaching post remains open. And Vermes remains an intriguing candidate.

Although he has been vague about his potential attraction to the position, The Star spoke with some of his acquaintances from outside clubs over the past few weeks, and they believe he would be interested under the right circumstances.

 

Research: We Take More Risks When We Compete Against Rivals

Harvard Business Review; Christopher To, Gavin Kilduff, Lisa D. Ordóñez and Maurice E. Schweitzer from

Rivalry is everywhere. We see rivalries in sports, business, school, and basically any arena where there is competition. Whether it is rivalry between people (Bill Gates versus Steve Jobs; Roger Federer versus Rafael Nadal), between organizations (e.g., Ford versus GM), or between nations (e.g., should U.S. soccer fans have rooted for rival Mexico in the World Cup?), there is something uniquely powerful about rivalry that differentiates it from others forms of competition and relationships.

There are many stories highlighting the benefits of rivalry, from how it makes competitors more motivated to how it helps them perform better. For example, the rivalry between the Beatles and the Beach Boys is thought to have pushed both groups to greater levels of creativity and performance in their song-writing. Similarly, the rivalry between Intel and AMD is thought to have helped advance computer chip technology.

Yet despite the wealth of anecdotal evidence, scientific research into such rivalry relationships is scarce. We’ve spent the last few years studying what makes rivalry unique, how it affects our behavior, and how it impacts organizations.
