Giannis Antetokounmpo is dunking on teams like a modern-day Shaquille O’Neal

NBA.com, Scott Rafferty from

… Of the 259 shots Antetokounmpo has made so far this season, 118 have been recorded as dunks. According to Basketball-Reference, the only players since 2000-01 to average at least 20 points per game and throw down dunks at that high of a rate are O’Neal and Howard.

 

In His Words: Zack Steffen on Taking the Next Step for Club and Country in 2018

U.S. Soccer from

My family is a big part of my life. I was 19 when I went to Germany, and it was tough not having them around. It just didn’t feel right. So when I joined the Columbus Crew, it felt like home right away. Over the last two years, they’ve made it to just about every home game, and that’s exactly how I wanted it to be – to have a career that I could share with my family and have them next to me while I began this ride.

One of the best life lessons my parents instilled in me is that there will always be ups and downs…both in life, and in soccer. But you have to learn from them, and when you’re going through them, you have to stay humble and stay grounded – no matter what.

And that’s the thing about me – when there are downs, I get over those quickly.

 

Detroit Lions WR Kenny Golladay exceeding his own goals

Detroit Free Press, Dave Birkett from

Kenny Golladay has far exceeded his own expectations in his breakout second season, and the Detroit Lions receiver appears poised for even better in years to come.

Golladay, coming off a seven-catch, career-high 146-yard game in Sunday’s 14-13 loss to the Buffalo Bills, said Monday he has eclipsed every individual goal he had coming into the season, in part because of the thinned-out cast around him.

“Well of course I wasn’t expecting to be by myself, so that plays a factor in it,” Golladay said. “You got to think, I was with two other guys. One guy left and now there’s just two of us, and then he gets injured and now it’s just me. So it’s different. So the goals I did set, I kind of blew those out the water, which is good. Which is good. Like I just said, it just gives these coaches an opportunity to see what I can do by myself with not the help of other guys around me.”

 

Kevin De Bruyne denies exhaustion caused six-week absence

The Guardian, Nick Ames from

Kevin De Bruyne has denied he felt tired at the end of last season but admits a summer break of three weeks was not long enough after almost a full year of exertion.

The Manchester City playmaker could start Tuesday’s Carabao Cup quarter-final at Leicester, having returned from a six-week absence to make a substitute appearance against Everton on Saturday. He has played only five times this season, three of them from the bench, after sustaining injuries to both knees and last week Pep Guardiola suggested De Bruyne was so “exhausted” the enforced rest may have the effect of freshening the player mentally for the next five months.

“Maybe, but I’m not sure I agree with that,” De Bruyne said. “I played the most of anyone last year – in the whole world. And I played the World Cup without a problem. I think the most important thing is having a summer break; if you have that you can feel OK, but there is always a time in someone’s career where you feel a bit less.

A lifelong runner and outdoor athlete is hit with a mysterious physical breakdown. Once the engine starts to fail, what happens to the mind?

 

The influence of running velocity on resultant tibial acceleration in runners. – PubMed – NCBI

Sports Biomechanics journal from

Tibial acceleration is a surrogate measure for impact loading and might be useful for identifying lower limb fatigue injury in runners. The resultant tibial acceleration calculated from all three axes of a triaxial accelerometer provides a single metric that is independent of the sensor orientation. The purpose of this study was to investigate the relationship between resultant tibial acceleration and running velocity, and to establish a normative database of tibial acceleration profiles. Triaxial accelerometers were attached to the distal tibiae of 85 runners before they ran on a treadmill for 2 min each, at speeds of 2.7, 3.0, 3.3, and 3.7 m/s. Differences in resultant tibial acceleration were calculated using a one-way ANOVA, and the relationship between tibial acceleration and velocity was determined using a Pearson correlation coefficient and a multiple linear regression analysis. Tibial acceleration increased with higher velocities, with an average increase of 3.8 g (38%) between the slowest and fastest speeds. A moderate correlation was demonstrated between tibial acceleration and running velocity, and 19% of tibial acceleration was explained by velocity. While velocity influences tibial acceleration, individual variances to this relationship exist, highlighting the need for a personalised approach to understanding the response of each runner.

 

Man Utd the only team not to use GPS under Mourinho

Training Ground Guru, Simon Austin from

Manchester United were the only team in the Premier League not to use GPS after Jose Mourinho scrapped use of the technology.

GPS is widely used to track the physical performance of players, providing data such as distance covered, number of sprints and top speeds. This is regarded as being important in assessing the fitness of players and monitoring their training.

It is widely used at first team and even Academy level by top clubs and one Premier League practitioner has described the distinctive GPS vests as being “as much a part of the modern player’s kit as their shin pads and boots”.

 

Proper Running Form Is a Lie

Runner's World, Lauren Steele from

… “Perfect running form is theoretical,” says Dr. Colleen M. Brough, Board Certified Orthopedic Clinical Specialist and Director of Clinical Education at the Columbia University RunLab. “It depends on each runner as each runner has a signature form that will minimize injury and attenuate stress and load optimally.”

What she’s saying is, to prevent injury and keep yourself on the road, there’s no golden technique every runner should follow. Instead runners should run however feels natural and comfortable. That’s the most efficient stride and best technique to minimize injury.

“I worked with a four-time Olympic marathon qualifier—that’s 16 years of Olympic-level running,” Brough says. “Yet, I’ve never seen such exaggerated pronation as I saw in this accomplished runner. All of those years of health and high-level running without sidelining injury debunks for me the myth of perfect form.”

 

VitalPatch Biosensor and VistaTablet Monitor: A Medgadget Review

Medgadget, Mohammad Saleh from

In the summer of 2018, VitalConnect launched the VistaTablet as an extension to their FDA-approved biosensor, the VitalPatch, which measures eight vital parameters. We have previously covered the VitalPatch and the launch of the VistaTablet, but we recently had the chance to check them out first-hand. The following is a review of this editor’s experience and impressions.

 

Stretchable Thermoplastic Elastomer Optical Fibers for Sensing of Extreme Deformations

Advanced Functional Materials journal from

The design of advanced materials with coupled optical and mechanical properties is an important challenge in materials science; especially, the implementation of soft materials in optics has recently gained significant interest. Soft optical systems are particularly versatile in sensing, where large and repeated deformations require dynamically responsive materials. Here, stretchable step‐index optical fibers, which are capable of reversibly sustaining strains of up to 300% while guiding light, are demonstrated. A continuous and scalable melt‐flow process is used to coextrude two thermoplastic elastomers, thereby forming the fibers’ high index core‐low index cladding structure. Deformation of the fibers through stretching, bending, and indentation induces detectable, predictable, reversible, and wavelength‐dependent changes in light transmission. Quantitative knowledge about the coupling of the fibers’ mechanical and optical properties forms the basis for the design of fiber‐based sensors that are capable of reliably assessing extreme mechanical stimuli. The fibers utility in sensing scenarios is demonstrated in a knee brace for continuous knee motion tracking, a glove for control of a virtual hand model, and a tennis racket capable of locating ball impacts. Such devices can greatly improve quantitative assessment of human motion in rehabilitation, sports, and anywhere else where large deformations need to be monitored reliably.

 

Omron gets FDA clearance for HeartGuide, a blood pressure monitor for your wrist

Wareable (UK), Hugh Langley from

For almost two years Omron, maker of blood pressure monitors, has been working on a watch that’s able to take oscillometric blood pressure readings from the wrist. The company has just revealed that it’s secured FDA clearance for “Project Zero” – now officially named HeartGuide – and that the watch will be available in January.

The HeartGuide watch, which we first glimpsed at CES in January, uniquely hides a blood pressure cuff under the watch strap, which can inflate at set intervals through the day and night to take – so Omron claims – medically accurate readings.

 

Identification of muscle fatigue by tracking facial expressions

PLOS One; Marco C. Uchida et al. from

Resistance training (RT) is performed at distinct levels of intensity from the beginning to the end of exercise sets, increasing the sensation of effort as the exercise progress to more vigorous levels, commonly leading to changes on the facial expression of RT practitioners. The objective of this study is to evaluate changes in facial expressions using the Facial Action Coding System(FACS) and the activation of facial muscles by surface electromyography(sEMG) at two different levels of effort during resistance exercise and to investigate the correlation between facial expression and exercise intensity and fatigue. Eleven healthy male participants [23±6years; 1.77±6 m; 78±10kg] performed a set of arm curl exercise at 50% and 85% 1RM until muscle fatigue. The Surface electromyography (sEMG activity was recorded simultaneously in areas of the epicranius muscle (EM) and zygomatic major muscle (ZM). Facial expression was recorded and blindly scored by five experienced examiners. Scores (0–5) were based on the level of activity of the ZM (lip corner puller—Action Unit 12-FACS) during exercise. Facial expression and sEMG data were obtained during the exercise at the first repetition and at muscle failure. The root mean square (RMS) of the sEMG amplitude of the EM was significantly increased between the first and last repetition (50%1RM:p = 0.002,d = 1.75; and 85%1RM:p = 0.002,d = 1.54). The RMS values for the ZM were significantly increased between the first and last repetition (50%1RM:p<0.001,d = 2.67; 85%1RM:p<0.001,d = 0.50). The RMS values for the ZM were also increased in 85%1RM compared to values obtained from 50%1RM (p = 0.001,d = 1.12) at the first repetition. AU12 scores and RMS values were not statistically different between 85%1RM and 50%1RM at the last repetition. Furthermore, there was a strong correlation (r = 0.61;p = 0.045) between AU12 scores and the sEMG peak for the ZM. In conclusion, changes in facial expression may be directly correlated with different resistance exercise intensities and fatigue.

 

The NCAA’s Dominance Is Weakening. Enter the G League

OZY, The Huddle, Evan Fleischer from

… It’s clear that the G League is positioning itself to serve as an attractive alternative to college for such players. And, as it turns out, it might be a more reliable path to the NBA.

Consider this: Only 1.2 percent of 18,712 NCAA basketball players get called up to the NBA. And college basketball players can’t profit off their own likenesses, despite the fact that those same likenesses generate millions of dollars in revenue every year for their programs.

 

Bowl games are lucrative for everyone but those putting their careers on the line

The Washington Post, Barry Svrluga from

As we enter the thick of college football bowl season, let’s call it what it is: programming inventory for the behemoth that is ESPN. Who could wait for Tuesday night’s Cheribundi Boca Raton Bowl, featuring UAB and Northern Illinois, two programs that plain don’t like each other? Why, that was just an appetizer for Wednesday’s DXL Frisco Bowl, with San Diego State out to prove its fourth-place finish in the Mountain West Conference’s West Division was no fluke against Frank Solich’s Ohio Bobcats, co-runners-up in the Mid-American Conference’s East Division. Batten down the hatches, indeed.

The new, lousy reality — from a programming and therefore a viewing standpoint only — is that however obscure the bowl game, there’s a chance the best available players aren’t even playing in it. This is a phenomenon that will affect the Hyundai Sun Bowl (Bryce Love, Stanford), the Camping World Bowl (Will Grier and Yodny Cajuste, West Virginia), the TaxSlayer Gator Bowl (Germaine Pratt and Kelvin Harmon, N.C. State), the Chick-fil-A Peach Bowl (Rashan Gary, Michigan) and at least seven other games.

Those players are among more than a dozen college stars who, after being taken advantage of for at least three years, have picked the holiday season to stop giving back. They’re skipping their final chance to wear their college uniforms. If there’s any sort of outcry over this, let it cease here and now. It’s their right. It’s their health. These are their careers at stake.
