The transformation of Markelle Fultz

The Boston Globe, Adam Himmelsbach from

… On Friday night, a source close to the point guard said he was simply waiting to see what developed and that he would continue to prepare just as he had before.

While many elite NBA prospects have shuffled off to work with renowned trainers in splashy facilities in places like Los Angeles and Las Vegas, Fultz, 19, has maintained a more familiar and simple routine at home in Maryland. Twice a day he goes to whatever gym will have him, and he even has a key to the facility at his alma mater, DeMatha Catholic High, where his workouts have lasted until 3 a.m. before.

Fultz does not give off the vibe of someone who will earn a $6 million salary next season if he is drafted first overall. At his mother’s house, he still mows the lawn and does the dishes and sleeps in his childhood bedroom.

 

Sidney Jones back with Eagles, preparing like he’s going to play

CSN Philly, Reuben Frank from

… Jones, expected to be a high first-round pick in this year’s draft, fell to the Eagles at No. 43 in the second round after suffering a torn Achilles during his pro day in March.

“It won’t be a lost year,” defensive backs coach Cory Undlin said Monday. “Whenever he comes back, he’s going to be behind, but he’s showing up every single day like he’s going to play this year.

“Now is he? I have no idea. He has no idea. But we are going about our business on a daily basis like he’s going to play, so his mindset has to be exactly the same. Will he be a little bit behind? He’ll be behind because he hasn’t had these reps.”

 

Why Andrew Luck’s recovery is so far behind Cam Newton’s

The San Diego Union-Tribune, ProFootballDoc from

… The big difference is that Luck needed sutures and, thus, extended time for healing, while Newton’s recovery does not involve waiting for tissue regrowth.

The labrum is fibrous tissue that deepens the glenoid (socket) to help hold the humeral head (ball) in place. However, the shoulder is not a true ball and socket joint, like the hip joint is, but rather more golf ball (humeral head) on a tee (glenoid).

A labral tear essentially means the tee (glenoid) is chipped, making it hard for the golf ball (humeral head) to stay in place. This shifting causes shoulder problems and the goal of repair is to stabilize the shoulder.

 

Shoulder experts speak: Is Andrew Luck on schedule?

Indianapolis Star, Zak Keefer from

… “No pressure on Andrew – none,” new General Manager Chris Ballard said this spring. “I want to do what’s right for Andrew and his career. We’re not going to force Andrew Luck and put a timetable on him and say, ‘You have to be back by this time.’ This is a team game, and it’s our job to put enough around him and find a way to get it done if he’s not in the mix. And if he’s not ready right away, we’ll move forward.”

But, five months into what is expected to be a six-to-nine month recovery, where should Luck be at this stage? What, exactly, is happening inside that oh-so-important-appendage? And what’s up with Luck’s noticeably thinner appearance?

Discussions with multiple shoulder specialists indicate one thing: There is no cause for concern. Yet.

 

Use of a tibial accelerometer to measure ground reaction force in running: a reliability and validity comparison with force plates – Journal of Science and Medicine in Sport

Journal of Science & Medicine in Sport from

Objectives

The use of microsensor technologies to conduct research and implement interventions in sports and exercise medicine has increased recently. The objective of this paper was to determine the validity and reliability of the ViPerform as a measure of load compared to vertical ground reaction force (GRF) as measured by force plates.
Design

Absolute reliability assessment, with concurrent validity.
Methods

10 professional triathletes ran 10 trials over force plates with the ViPerform mounted on the mid portion of the medial tibia. Calculated vertical ground reaction force data from the ViPerform was matched to the same stride on the force plate. Bland-Altman (BA) plot of comparative measure of agreement was used to assess the relationship between the calculated load from the accelerometer and the force plates. Reliability was calculated by intra-class correlation coefficients (ICC) with 95% confidence intervals.
Results

BA plot indicates minimal agreement between the measures derived from the force plate and ViPerform, with variation at an individual participant plot level. Reliability was excellent (ICC = 0.877; 95% CI = 0.825–0.917) in calculating the same vertical GRF in a repeated trial. Standard Error of Measure (SEM) equalled 99.83 units (95% CI = 82.10–119.09), which, in turn, gave a Minimum Detectable Change (MDC) value of 276.72 units (95% CI = 227.32–330.07).
Conclusions

The ViPerform does not calculate absolute values of vertical GRF similar to those measured by a force plate. It does provide a valid and reliable calculation of an athlete’s lower limb load at constant velocity.

 

Arsenal to appoint Liverpool’s former head of fitness as new director of high performance

The Telegraph (UK), Jason Burt from

… it appears that Burgess’ planned role encompasses everything apart from player recruitment and scouting, and is a sign that Wenger has won his battle to ensure Arsenal did not appoint a director of football.

Burgess worked at Liverpool from 2010 to 2012, where the players rated him highly. He then returned to Australia, where he had previously been in charge of fitness and conditioning for the Socceroos national team that reached the 2010 World Cup finals in South Africa.

 

Persistence in Education

The Center for Innovative Research in Cyberlearning (CIRCL) from

This primer unpacks some of the big ideas behind grit, tenacity, and perseverance. These days, perseverance has become part of the everyday language of education. The misconception that intellectual power alone can enable students to succeed in school and life is giving way to a deeper understanding that attaining long-term and higher-order goals can depend so much on how people deal with inevitable obstacles, setbacks, and challenges. This is consistent with extensive correlational research that shows, for example, that conscientiousness (“dependability and will to achieve”) is as closely tied with academic success as intellectual ability (Poropat, 2009); for adults, it is also associated with income, wealth, and life satisfaction (Duckworth et al., 2012).

But what are grit, tenacity, and perseverance, and how can educators create environments and experiences that promote them? This primer discusses highlights from a report on a broad synthesis of research and practice based on interviews of 27 high-profile thought leaders and reviews of the pertinent research in education and psychology (see Shechtman et al., 2013). We also reviewed approximately 50 programs, practices, and technologies intended to promote perseverance in a variety of ways. This was not an exhaustive review, but it revealed key themes in the ways that educators are approaching these issues and suggested ways that digital technologies might be used to expand learning environments to support perseverance. One example from the CIRCL community is the work of Arroyo, Stephens, Woolf, Maloy, Burleson, and Muldner, who are exploring new ways that technologies can be responsive to students’ struggles as they learn.

 

Science of baseball evolving: Help pitchers avoid injuries

USA Today Sports, Ray Glier from

… Major League Baseball is funding an ASMI study on lowering the mound from 10 to 6 inches. A spokesman for MLB says the study is being done in the interest of arm safety. (Minor league and college pitchers also pitch from a mound that is 10 inches high.)

What if a lower mound means less velocity but healthier pitchers? Fleisig says ASMI will measure velocity in the study.

A move to lower the mound height could have a dramatic impact on the game. After all, when the mound was lowered 5 inches in 1969 (15 inches to 10 inches) after a season of dominance by pitchers in 1968, hitters regained some luster. A reduced strike zone in 1969 surely had impact, but mound height was significant. National League ERA went from 2.99 in 1968 to 3.59 in 1969. AL ERA went from 2.98 to 3.62.

 

Fifa ex-medical officer criticises decision to end health project

BBC Sport from

Fifa’s former chief medical officer has criticised the body’s decision to end a project educating children on how to avoid diseases like malaria and HIV.

Fifa says its ’11 for Health’ programme, promoted by Real Madrid’s Cristiano Ronaldo and Barcelona’s Neymar, had “limited impact”.

But Jiri Dvorak told BBC World Service: “I was convinced we might help impact the health of the future generation.”

 

New Zealand rugby joins NFL-funded concussion study

ESPN Rugby, Tom Hamilton from

New Zealand’s Super Rugby teams and players are participating in a concussion-related study funded by the NFL.

The study — costing $2.6 million (AUS$ 3.41m, £2.03m) and directed by the University of North Carolina and the Medical College of Wisconsin — is looking into a new, multi-dimensional concussion recovery programme.

Rugby players currently undertake a six-day return-to-play protocol, guiding them back to the field after suffering a head knock. If a player has any concussion-related symptoms throughout the process, then they return to the start until they are symptom-free.

 

Passing Percentages Are Mostly Useless – Quantifying Passing Ability

StatsBomb, Ted Knutson from

… Think about it… Your average football match features 3 or fewer goals.

And about 25 shots.

And around 1000 passes.

Machine learning today is far from perfect, explains UX designer Mike Kuniavsky of PARC Research. A poorly conceived internet appliance can be worse than useless: a labor creating device.

 

Is any team having more fun than the Houston Astros?

ESPN, SweetSpot blog, Scott Lauber from

… general manager Jeff Luhnow knew something was missing last season when Houston encountered problems during a 7-17 April and never fully recovered. For all their talent, the Astros still lacked experience. They needed the steady hand and respected voice of a veteran player who has been through struggles and lived to tell about them.

The Astros needed Beltran. And Reddick. And catcher Brian McCann.

“We were a young team last year with a lot of talent but no leader in the team that can lead us the right way,” Correa says. “I feel like they’re leading us down the right path, which is winning. They’ve been there before. They’ve been with great teams before. They’ve been in the playoffs before, so they know how to win. They know what it takes. They’re bringing this team together in order for us to have the season we’re having.”

 

Browns offensive line coach Bob Wylie explains NFL combine card game

cleveland.com, Dan Labbe from

… Makes sense, but how does it all apply to football?

“So he has to process the information, he has to see it, like you would on the field, he has to process the information and now the ball’s coming up, so you only get a few seconds to do that. So if they can do that, then I keep with them. If they can’t do that, like I give them nine of the things to do, if they get one or two, the red flag goes up. You can’t process the information fast enough, especially at this level.”

It all goes back to the differences between playing in a college offense vs. a pro offense.
