Are children born in fall more athletic?

Do you dream of having a child who grows up to be a superstar athlete? Or at least one who isn't picked last in gym class? You might want to take a look at this.

"There's a new study in the Journal of International Sports Medicine that found that children born in the fall have an edge when it comes to physical fitness." (Via ABC)   

The Guardian reports researchers at the University of Essex in Great Britain studied more than 8,000 children ages 10-16 for three measures of fitness: stamina, handgrip strength and lower-body power.

Researcher Gavin Sandercock says: "A boy born in November can run at least 10 percent faster, jump 12 percent higher and is 15 percent more powerful than a child of the same age born in April." (Via The Guardian

So what makes a November baby more likely to be the next LeBron James and an April baby more likely to watch on the sidelines? The researchers hypothesize the cause is the sun.

But another explanation could be something we're doing instead of a natural cause.

For years, researchers have been studying birth month phenomena. The BBC reports in 2009, 57 percent of players in professional English youth academies had been September, November or December babies, and a mere 14 percent were born in June, July or August.

The theory of relative age effect says the September cutoff dates we impose in school allow children with birthdays immediately after the cutoff to be almost a year older than those born in July and August. According to the BBC, this means they're more physically developed than their classmates.

Because sports today are often through structured leagues, this early advantage in size leads to a greater chance of moving up to better teams with better coaching. (Via Flickr / USAG-HumphreysThe Wall Street Journal)

But if you happen to be a summer birthday don't fret yet. Superstars like Kobe Bryant have been born in the summer. (Via Flickr / Aaron Frutman)

And in the end, it's really all about loving the game.

  • Of the nation’s 100 most populated cities, only one was deemed the best of the best for Fourth of July: Atlanta. » RELATED: Atlanta festivals and Fourth of July weekend events | July 1-4 Based on five key dimensions (celebrations; affordability; attractions and activities; safety and accessibility and Fourth of July weather forecast), analysts at personal finance site WalletHub named our very own metro the top city in the nation to celebrate Independence Day. Analysts examined 18 relevant metrics to reach the verdict, including legality of fireworks, number of festivals and concerts, walkability and prices of beer, hamburgers and more. » RELATED: America’s 10 biggest and brightest Fourth of July fireworks shows They used data from the Census, Council for Community and Economic Research, Eventbrite and several other sources for the ranking. Atlanta earned a total score of 78.01, making it in the top 10 for the celebrations and attractions/activities dimensions — and rightfully, so. Check out all the happenings around town for the big holiday: The Dunwoody 4th of July Parade Decatur’s Pied Piper Parade Chamblee 4th of July Celebration Fourth in the Park on Marietta Square 4th of July at Centennial Olympic Park Fourth of July at Stone Mountain Park Coca-Cola July 4th Fest at Six Flags Over Georgia The AJC Peachtree Road Race And most of those celebrations listed don’t even include the endless list of fireworks extravaganzas, including the popular Atlanta Braves fireworks, the Star-Spangled display at Mall of Georgia or the Callaway Gardens Beach Party show. Remember, the popular Lenox Square fireworks are a thing of the past, but the mall announced it is partnering with Centennial Olympic Park for “a more spectacular fireworks show than ever before.” » RELATED: More 4th of July fireworks, parades and attractions in Atlanta Rounding out the top five on WalletHub’s list of the best places to celebrate Independence Day were San Francisco, California; Buffalo, New York; Washington, D.C.; and San Diego, California.

  • Danish shipping conglomerate A.P. Moller-Maersk was one of multiple European companies to fall victim Tuesday to a cyberattack as Ukrainian government officials reported a “large-scale hacker attack” across the country. >> Read more trending news Attacks were also reported in several other countries, Russia cybersecurity firm Kaspersky Lab said in a statement, including the United States, Russia, Poland, Italy, the United Kingdom, Germany and France.
  • The public should be careful of what they touch. As the opioid drug epidemic grows, Marietta police are warning of a possible hidden danger that could be lurking in public places such as restrooms, hotel rooms, even rental cars. Officer Chuck McPhilamy tells WSB, 'What happens to the average hotel worker that's at any hotel in the city cleaning a room that happened across some residue?'   Anyone who comes in contact with drug residue could be at risk.  McPhilamy says drugs laced with Fentanyl can be absorbed simply by touching it. He says 'That changes the game,' and 'changes our concern level.'  McPhilamy says, 'It can be inhaled through your nose or your mouth, it can be absorbed through your skin or your eyes.' A concern is the average person may have no idea what the drugs look like.  McPhilamy says, 'Fentanyl itself can come in so many different forms it's not like I can tell you just look for one substance.' There have been no reports of this happening in Georgia.  McPhilamy says he doesn't want to cause a panic, but he wants people to be aware. Even if a person is not a drug addict, they may come across people who use or sell these potentially dangerous drugs.  He says, 'I think we're talking about two different cultures intersecting.' If anyone sees something that looks suspicious, police say call 9-1-1, and if one should start feeling ill, get medical attention immediately.    
  • The FBI says it has located the car that a missing Chinese scholar studying at the University of Illinois was last seen getting into earlier this month. The FBI said in a Tuesday statement that it's received 'numerous leads' regarding the black Saturn Astra and won't need any further information on the vehicle. Authorities also said they've developed 'several additional leads' in the investigation. FBI spokesman Brad Ware declined to give further details. Twenty-six-year-old Yingying Zhang's disappearance has been labeled a kidnapping but police haven't ruled out other scenarios. Surveillance video on June 9 showed her getting into the vehicle. Local police and the FBI say Zhang's case is top priority. Zhang's family members have traveled to the central Illinois school and are staying in university housing as the search continues.
  • Some Costco locations are serving up a new burger -- and it’s causing chatter beyond the food court.  >> Read more trending news Observations of the new burger have circulated for weeks, and it’s making headlines because food critics are comparing it to a Shake Shack burger. Shake Shack, a popular chain that hasn’t made it to the northwest U.S., builds its burger with all-natural Angus beef, a “Chicago-style” potato bun, the Shack's sauce, which is made up of mayo, dijon mustard and dill pickle brine. >> Related: Dick's Drive-In makes ‘25 Best Cheeseburgers' national list “The final product looks nearly identical to Shack's beloved burger, though the ingredients are slightly different,” wrote Delish.com's Rheanna O’Neil Bellomo, who simply called it a “Shake Shack copycat.” Ingredients in the 1/3 pound Costco burger are reported to be an organic beef patty, topped with romaine lettuce, and smoke Thousand Island dressing. >> Related: This essay about Costco got a high school senior into 5 Ivy League schools When the Seattle Times checked in with Costco Corporate about Seattle as a test market, it wouldn’t confirm the cheeseburger.
