Effectiveness of early sport specialization limited in most sports, sport diversification may be better approach at young ages

Apr. 23, 2013 ? Ever-increasing requirements for success in competitive sports has created added pressure for young athletes to train with greater intensity at earlier ages. The goal to become the next Olympian or more commonly, to obtain a college scholarship, motivates many parents to encourage their children to specialize in one sport at a young age. This has resulted in an increased demand for year-round sport training programs, facilities and products. But is this approach really an effective way to generate long-term success in competitive athletics?

John P. DiFiori, MD, President of the American Medical Society for Sports Medicine, Chief of the Division of Sports Medicine and Non-Operative Orthopaedics at the David Geffen School of Medicine at UCLA and Team Physician for the UCLA Department of Intercollegiate Athletics, says that few who specialize in one sport at a very young age make it to elite levels. "With the exception of select sports such as gymnastics in which the elite competitors are very young, the best data we have would suggest that the odds of achieving elite levels with this method are exceedingly poor. In fact, some studies indicate that early specialization is less likely to result in success than participating in several sports as a youth, and then specializing at older ages."

Dr. DiFiori encourages youth attempt to a variety of sports and activities. He says this allows children to discover sports that they enjoy participating in, and offers them the opportunity to develop a broader array of motor skills. In addition, this may have the added benefit of limiting overuse injury and burnout.

A UCLA sports specialization study surveying 296 NCAA Division I male and female athletes, average age 19, found that 88 percent participated in an average of two to three sports as a children, and 70 percent did not specialize in one sport until after the age of 12. In a similar study of Olympians in Germany, results found that on average, the Olympians had participated in two other sports during childhood before or parallel to their main sport. Both studies support the concept of sports diversification in adolescence -- not specialization.

In his nearly 20 years serving as a team physician for the UCLA Department of Intercollegiate Athletics, Dr. DiFiori appreciates the benefits of sports participation in general -- increased self-esteem, self-discipline, development of leadership qualities and social skills, and overall health and well-being. But he warns external pressure on a child to train and compete in one sport at an early age may cause more harm than good. Social isolation, lack of independence, preferential treatment, abusive relationship, burnout and injury are some of the potential negative effects.

"Physical activity contributes to a happy and healthy childhood," says Dr. DiFiori, "however, parents, coaches and children should monitor and measure their involvement level in a singular sport against the overall well-being and future success of the participant."

Dr. DiFiori presented, "Early Sports Participation: A Prescription for Success?" on Thursday, April 18, 2013, at the annual meeting of the American Medical Society for Sports Medicine in San Diego, Calif.

Deadly day in Mogadishu shows weakened Somali militants not yet defeated

Al Shabab militants in Somalia killed 19 people Sunday in three bomb attacks that targeted Mogadishu's main court complex and an aid convoy.

Al Shabab militants killed 19 people Sunday in bomb attacks that targeted Mogadishu's main court complex and an aid convoy, underscoring the fact that Somalia?s weakened Al Qaeda-allied militia has not yet been beaten.?

The first of three bomb attacks exploded just before noon local time Sunday outside the Mogadishu courthouse. ?Gunmen camouflaged in Somali Army uniforms then stormed the buildings and opened fire.?It was the worst day of killings in the capital since late last year, and spoke to the militants' ongoing capabilities despite a series of recent setbacks.?

??These attacks appear to have been coordinated and well-planned,? says a political source close to the Somali government.?

"It seems clear that they wanted to target symbols of Somalia's political and judicial progress in the past year, and thought that killing lawyers and court officials would appeal to people they think still support them," the source says, adding that "I think in fact that that support is waning with every one of these attacks."

As state security forces fought to contain the insurgents, several lawyers, court officers, and bystanders died in the gunbattle, sources in Mogadishu reported. A second bomb was detonated during the firefight.?

Two of the counsels killed were Mohamed Mahmud Afrah, a law professor and head of the Somali Lawyers? Association, and Karim Hussein Gorod.?

They had represented Abdiaziz Abdinur, a Somali journalist jailed after he interviewed a woman who had been raped by Somali soldiers in Mogadishu. Mr. Abdinur was released last month after an international outcry.

Less than two hours after the court attack, the third bomb exploded close to a Turkish Red Crescent and African Union convoy near the airport.?

Casualty figures not yet clear

While as many as 19 people were reported to have been killed in the blasts, one hospital worker tells the Monitor that casualty figures were not yet clear.?

?We have eight bodies in the morgue here and there are another three people who are critically wounded,? the hospital worker says, refusing to give his name because he is not authorized to talk to the media.??There are others in other hospitals but I don?t know how many. It has been a long time since we have seen this level of casualties here.??

Three of the gunmen who stormed the court complex wore suicide vests that they detonated, witnesses reported, but this could not immediately be verified.?

Many of those killed at the court wore Somali Army uniforms, but several were reported to be Al Shabab agents disguised as state soldiers to gain access to the buildings during the confusion.?

Al Shabab has been pushed out of most of the key towns that it controlled in southern Somalia after a stepped-up offensive by African Union peacekeepers allied with Kenyan and Ethiopian troops. But its commanders have vowed to strike back with insurgent-style tactics including car bombs, suicide attacks, and roadside bombs.?

"We carried out a superb intense mission in Mogadishu today,? Sheikh Ali Mohamud Rage, an Al Shabab spokesman, said Sunday.??We assigned five special mujahideen for the court. Four of them entered and killed the people inside. The other mujahid with his car bomb exploded when government soldiers gathered at the gate.?

(AP) ? If you're upset that the Rolling Stones won't be coming to your city on their upcoming tour, don't be too stressed ? the rockers say more shows may be added.

"Normally when you announce a tour like this, you announce part of it, you leave it to be, you see what happens, you might do a date here and another date there. You don't want to be completely hand fast, so you do leave some dates in between," Mick Jagger said in an interview Thursday. "So we'll see what happens."

The Stones announced this week that they'll kick off their "50 and Counting" tour in Los Angeles; the date will be announced later. The second show is in Oakland, Calif., on May 5. They'll also visit Las Vegas, Toronto, Chicago and Boston, and wrap in Philadelphia on June 18.

On Friday, the band said second shows have been added in Toronto and Chicago.

The announcement came months after the foursome performed a sold-out, five-city stint in New York, New Jersey and London.

Jagger called those shows a test.

"We just said, 'Let's do these five shows before Christmas and see how it goes and see if we enjoy it, see if the audience seems to have a good time, and if that works, then we'll try to see if we'll do more,'" he said. "We still wanted to keep it kind of limited. We didn't want to have that yawning (tour) of hundreds of shows lined up for the next 18 months. I just thought it would be good if we booked a small tour, and then, you know, if we want to do more, we'll do more."

The Stones have at least three days in between tour stops, a sign that more shows may be added. Or the time could be used for rest.

"I think it's a little bit of both," Keith Richards said in a separate interview Thursday. "The band wants to pace themselves, but at the same time ... I guess what's been announced is the bare-bones and we will play it by ear from there."

The Stones' last global tour kicked off in 2005 and wrapped in 2007.

Jagger, 69, said he's getting older ? and performing can be tough.

"I just have to train a lot and keep really fit. I want to do these moves, but I can't do them because if I did, I'd probably screw up," he said, laughing. "You just got to do what's within your capabilities. I don't want it to look wrong, so I'm going to stay within my boundaries."

The Stones' recent tour featured special guests such as Bruce Springsteen and Lady Gaga, and there could be more surprises onstage.

"I have a feeling there's more openness about playing it the same way," Richards said. "I can't name names or make promises, but that area of the show is open."

The veteran band, which also includes Charlie Watts and Ronnie Wood, will headline the Glastonbury Festival on June 29 and will perform at London's Hyde Park on July 6. Former bandmate Mick Taylor, a member of the Stones from 1969 through 1974, will be a special guest throughout the tour.

"I realized how much, not just (how I) myself have missed it, but I could tell from the other guys. They don't say so, but I can tell," Richards said of performing together. "It's what we're good at."
