Carli Lloyd Talks Fighting For a Spot on the Soccer Field: “Every Day Is Basically Like a Tryout”

Yahoo Lifestyle, PopSugar, Samantha Brodsky from

For two-time World Cup and Olympic champion Carli Lloyd, the seasons aren’t the only thing that will be changing come Summer. For her and the rest of the women on the US soccer team, their coach Vlatko Andonovski has the difficult task of trimming them down to 18 players – including two goalkeepers – prior to Tokyo 2020. It’s an interteam competition, constantly trying to prove your worth, but Carli told POPSUGAR before the Power House On Her Turf event on Feb. 13 that it doesn’t affect the connection these women have. And, fighting for a spot on the field is something Carli knows well.


‘I only get one chance at this’: Nolan Arenado wants the Rockies to field a winner

Yahoo Sports, Tim Brown from

… “You know what, and I want you please to write this down, the perception of me right now, some people have different things, right?” he said. “It’s, ‘Oh, you make money, keep your mouth shut. You signed this deal and this and that.’ But, at the end of the day, man, people misunderstand. Us, as players, we only get one chance at this. I only get one chance at this. I have seven years left on my deal. I don’t know how it’s all going to turn out. And I want to win.

Sports Illustrated, Grant Wahl from

Playing on the Champions League and Olympic stages and winning the Bundesliga title are all within reach for U.S. midfielder Tyler Adams—if he can stay healthy.


Fatigue matters: An intense 10 km run alters frontal and transverse plane joint kinematics in competitive and recreational adult runners

Gait and Posture journal from

  • Lower extremity joint kinematics change over a fatiguing 10 km run.
  • Hip adduction and ankle eversion change the most with running-induced fatigue.
  • With fatigue, the knee valgus angle increases.

    Mental fatigue and stress can seriously limit athletic performance, researchers say

    ABC News (Australian Broadcasting Corporation), Brittney Kleyn from

    Feeling mentally drained or stressed can seriously impact physical performance and motivation levels in sport and exercise, Queensland researchers have found.

    The findings are the result of months of work with the Queensland Firebirds netball squad and reveal how mental fatigue can have profound effects on athletic performance.

    University of Queensland researcher Suzy Russell, who headed up the study, said while much emphasis was placed on physical fatigue and recovery in sport, more needed to be done on the cognitive side.


    The effects of fatiguing exercise and load carriage on the perception and initiation of movement

    European Journal of Sport Science from

    Perceptual-motor coordination relies on the accurate coupling of the perceptual and movement systems. However, individuals must also be able to recalibrate to perturbations to perceptual and movement capabilities. We examined the effects of fatigue and load carriage on perceptual-motor coordination for a maximal leaping task. 23 participants completed an incremental fatigue protocol (light to fatiguing intensity stages) on two separate occasions (loaded/unloaded). At baseline and the end of every stage of the protocol, participants made perceptual judgments for the affordance of leaping. The accuracy of responses and reaction times were calculated and mean differences were assessed across exercise intensity and load carriage conditions. No interaction of exercise intensity and load carriage was detected, or main effect of load carriage. A main, quadratic effect of exercise intensity was detected on reaction times, with times decreasing through the moderate stage and increasing through post-fatigue. No effect of exercise/fatigue was detected on perceptual accuracy. The results indicate that exercise at high intensities through fatigue has a significant effect on perceptual-motor calibration. Contrastingly, in response to an action-scaled task, individuals can adequately recalibrate to increased load carriage.


    Australian Institute of Sport: a jewel destroyed

    The Australian, Jacquelin Magnay and Jessica Halloran from

    The federal government is considering what to do with the symbolic heart of sport, the Australian Institute of Sport, the soul of which has been destroyed by misplaced priorities.

    While one sports official catches the $40 bus from Sydney to Canberra to save his cash strapped sport as much money as possible, AIS executives are allowed to live interstate and are paid to fly in and out of the capital, flights and accommodation, all on the taxpayer.

    Millions have been spent on consultants — including $500,000 paid to the Seven Network for the “Find Your 30” advertising campaign — while prospective Olympic athletes and coaches have held sausage sizzles to raise the money to chase their Tokyo Olympic medal hopes.


    It’s Official: Screens Are Bad For Young Brains

    Parentology, Jenny Heitz from

    It’s no secret — screens aren’t the best babysitter for children. And now, a study that looks at screen time and children’s brain development shows, in blazing color, why they might be even worse for your kids than originally thought. In fact, the study, which was released in November 2019, indicates early screen use might actually impede your child’s brain development.

    Pictures of Kids’ Brains After Years of Screens

    The study, done by researchers at the Reading and Literacy Discovery Center of Cincinnati Children’s Hospital, showed actual images of five-year-old’s brains. Some of the kids experienced parents reading often to them, and little screen time. Other kids who’d had lots of screen time (more than one hour per day, the max recommendation by the American Academy of Pediatrics (AAP) and the WHO) throughout early childhood.


    Groundbreaking Device Enables 30 Days of Continuous Vital Signs Monitoring

    University of Colorado, CU Anschutz Medical Campus, Press Releases from

    BioIntelliSense, Inc., a continuous health monitoring and clinical intelligence company, today announces the U.S. commercial launch of its medical grade Data-as-a-Service (DaaS) platform and FDA 510(k) clearance of the BioSticker™ on-body sensor for scalable remote care. BioIntelliSense offers a new standard for Remote Patient Monitoring (RPM) by combining an effortless patient experience with medical grade clinical accuracy and cost-effective data services.

    “We are at the inception of a remarkable new era in healthcare that will employ medical grade sensor technologies to effortlessly capture remote patient data and generate personalized clinical intelligence,” said James Mault, MD, FACS, CEO of BioIntelliSense.


    ActiPatch Now Cleared for “All” Musculoskeletal Pain

    Orthopedics This Week, Walter Eisner from

    … The device, according to the clearance document, is a pulsed shortwave therapy device. “The circuitry consists of low voltage(3V) digital/analog electronics that control all timing functions to produce the therapeutic radiofrequency(RF) field, where the antenna is placed directly above the therapeutic site. This closed loop system of the antenna, low energy signal generator circuit, and battery power supply, transfers the RF energy to the target tissue as a localized therapy with no far field effects.”

    Again, according to the clearance document, the device operates at 27.12MHz shortwave frequency, pulsing at a 1000 pulses per second with a pulse width of 100μsecs. The duty cycle is therefore 10%. The power source is a 3Vbatter (CR2032), producing a peak spatial power density of 73 microWatts/cm2.


    The Biomarker Future is Digital

    Clinical Omics, Alice McCarthy from

    … As demand for preventive and precision healthcare continues to grow, so has the need for a new class of biomarkers. Ones that are highly portable, reliable, and immediate yet suffer no lack of precision or accuracy.

    Enter the domain of the digital biomarker.

    Digital refers to the method of collecting information. Instead of blood tests and medical imaging, digital biomarkers use sensors and algorithms across a plethora of available connected hardware and software tools. In this space, the patient is increasingly a consumer: one who wears, ingests, or has digital devices implanted. In many cases, these patient-consumers have some autonomy over when information is collected and with whom to share it.


    1. Develop a questionnaire 2. Ask others to use it 3. Get feedback on how it can be improved 4. Invite users to help improve it 5. Repeat

    Twitter, Ben Clarsen, British Journal of Sports Medicine from

    This process usually stops at 2, but delighted to have updated the OSTRC questionnaires.


    Social media users “copy” friends’ eating habits

    Ashton University (UK), News from

    The research, by Aston University’s School of Life and Health Sciences, found that study participants ate an extra fifth of a portion of fruit and vegetables themselves for every portion they thought their social media peers ate. So, if they believed their friends got their ‘five a day’ of fruit and veg, they were likely to eat an extra portion themselves.

    But conversely, the Facebook users were found to consume an extra portion of unhealthy snack foods and sugary drinks for every three portions they believed their online social circles did. The finding suggests we eat around a third more junk food if we think our friends also indulge.

    The Aston University researchers said the findings provide the first evidence to suggest our online social circles could be implicitly influencing our eating habits, with important implications for using ‘nudge’ techniques on social media to encourage healthy eating.


    Sources: Broncos, Rams cutting scouting combine attendance

    ESPN NFL, Adam Schefter from

    In what could portend the wave of the future, the Broncos are not sending their assistant coaches to the scouting combine in Indianapolis this year because they believe they’ll make better use of their time by watching film back in Denver, league sources told ESPN on Friday.

    Additionally, the Rams are not sending their offensive and defensive coordinators, Kevin O’Connell and Brandon Staley, to the combine because they would rather have them in Los Angeles implementing the team’s new offensive and defensive schemes, sources said.

    In a copycat league, the Broncos and Rams could be establishing a trend that other teams will follow, leaving coaches behind to watch the combine on TV and do their own scouting work in the office.


    Bielsa, Leeds and the TeamWork Index

    Medium, All Stats Aren't We from

    … Different teams find their own edge in different ways. As Orta has stressed over and over again, for Leeds, this edge is continuity.

    It is my contention that the Team Work Index explains one of the reasons why Leeds United are one of the best teams in the Championship and have been consistently successful for the last two seasons.
