BROOKLYN, NEW YORK - JANUARY 2: People run on treadmills at a New York Sports Club January 2, 2003 in Brooklyn, New York. Thousands of people around the country join health clubs in the first week of the new year as part of their New Year's resolution. Many health clubs see a surge in business of 25 percent immediately after the new year, only to see those numbers level off by spring. (Photo by Spencer Platt/Getty Images)

Is too much exercise bad for your health?

We all know regular exercise is key to good health, but apparently there can be too much of a good thing.

According to two recent studies, getting too much exercise can be dangerous to those with existing heart problems. (Via Wikimedia Commons / Kyle Cassidy)

One decade-long study published in the journal Heart looked at more than 1,000 older patients who were diagnosed with heart disease. Not surprisingly, the least physically active were twice as likely to have a heart attack or stroke than those who were more physically active.

But the German researchers also found that those who engaged in strenuous daily exercise were twice as likely to die ​from a heart attack or stroke than those who only moderately exercised a few times a week. (Via Flickr / Herald Post)

Older patients aren't the only ones who need to be aware of the dangers of too much exercising. A second study in the same journal found that even younger physically active men can develop heart problems, too.

Swedish researchers studied the physical activity of more than 44,000 men periodically over 12 years. They found that those who exercised more than five hours per week were 19 percent more likely to develop irregular heart rhythm than those who exercised less often. (Via Heart)

On the other hand, according to Medical News Today, study participants who were older than 60 and performed less-intense exercises, such as walking, were 13 percent less likely to develop a heart condition than those who did not exercise at all.

In a linked editorial, the authors also noted a difference in perceived exercise intensity at various age levels. 

"The intensity of exercise performed by 30-year-olds is higher than that performed by 60-year-olds, meaning that the same degree of exercise might be reported as moderate at 30 years of age and intense at 60." (Via Heart)

The Centers for Disease Control and Prevention says more exercise means more health benefits — even saying senior adults should go beyond the recommended amounts for younger adults.

However, these studies suggest that even though exercise is beneficial to a healthy lifestyle, there are some drawbacks with prolonged and high-intensity activities.

A medical professional not associated with either study told CBS that patients should be evaluated by a cardiologist who can set up a personalized exercise program. (Via United States Air Force)

She also endorsed the American Heart Association's guidelines, which recommend at least half an hour of moderate cardio five days a week and moderate muscle-strengthening activity two days a week.

  • A 15-year-old Florida teen is in custody at the U.S.-Canada border, hours after police discovered the body of a woman believed to be his missing grandmother in a shallow grave near the boy’s home, the Jacksonville Sheriff’s Office reported. Logan Tyler Mott was detained by the U.S. Customs and Border Protection as he tried to enter Canada from Buffalo, New York, sheriff’s deputies said. The Jacksonville Sheriff's Office had called Mott “armed and dangerous” and a person of interest in the death of his grandmother, 53-year-old Kristina June French. Mott was being watched by French at her Neptune Beach home while his father, a Jacksonville Sheriff’s Office corrections officer, was on vacation. Mott’s mother, Carrie Campbell-Mott, said the boy’s father, Eric Mott, was on vacation with his girlfriend. Eric Mott took an Uber home from the airport Wednesday after French never showed up to get them, Campbell-Mott said. When they got home, the door to their home was open and the house was ransacked, Campbell-Mott said. Eric Mott's guns were missing from a gun safe, Campbell-Mott said. French’s home in the Mayport area also was ransacked. Her weapons were gone, along with her Dodge Dart. Mott and French were reported missing after Logan didn't show up to high school on Monday or Tuesday. French also didn't show up for work Monday or Tuesday. A warrant was issued for his arrest Thursday on a charge of auto theft, deputies said. Originally, deputies believed that Tyler Mott and French may have been traveling together in the Dodge Dart. A missing child alert was issued by the Florida Department of Law Enforcement. The teen and the missing vehicle were spotted Thursday on surveillance video in south central Pennsylvania, the Jacksonville Sheriff’s Office reported. In a statement, Campbell-Mott she was “relieved” that her son was in custody. “We just ask for everyone to give us time to sort out what happened,” Campbell-Mott said. “That no matter what, Logan is our child and we love him and are standing by him to help in any way. We want to find out what happened to Kristina and we need time for that to happen.” Campbell-Mott said a sheriff’s detective will fly to meet Logan on Saturday. In a statement, the May Institute, a nonprofit organization that employed French, said it was “truly devastated” to learn of her death. “Kristina was a friend and a role model to so many people. … She was a true champion for people with disabilities and advocated tirelessly for human rights. “We have lost a beautiful person and she will be dearly missed. It is a very sad day.”
  • UPDATE 11/24/17 11:16 pm: JSO says Logan Mott has been detained by US Customs and Border Protection, as he tried to enter Canada from the Buffalo, New York area. ORIGINAL STORY: It's a tragic update in the days-long search to find a missing 15-year-old and his grandmother.  The Jacksonville Sheriff's Office announcing Friday afternoon they do believe foul play was involved, as they've recovered what they believe to be the body of 53-year-old Kristina French in the backyard of a Neptune Beach home connected to the two.  'The burial site was excavated today and human remains were located. They appear consistent with the description of Kristina French, but there will be no positive identification until the autopsy is completed by the medical examiner,' says JSO's Director of Investigations, Ron Lendvay.  At this point, JSO says 15-year-old Logan Mott is still missing, as is the silver Dodge Dart. Police say they do believe Mott is alive and in that vehicle.  'We have video surveillance of an individual we believe to be Logan Mott, with what we believe to be the car that's missing in this case, in south central Pennsylvania yesterday at 1:15 pm,' says Lendvay.  JSO says they're in the process of obtaining an arrest warrant for Mott for auto theft. He's also considered a person of interest in connection to the death of the person found in the backyard of the home on Seagate Avenue.  Police say Mott may also be in possession of firearms, as guns had been reported missing from that home, so if you do see him, you’re urged to call 911.
