It’s well-known that exercising to maintain a healthy heart also helps create a healthy mind. But several new studies suggest that when it comes to preventing dementia, not all forms of exercise are created equal.
Studies presented at this year’s Alzheimer’s Association International Conference found that resistance training was particularly beneficial for improving the cognitive abilities of older adults.
While the studies were small, all including 150 participants or less, they did seemed to indicate that resistance training – such as weight lifting or using resistance bands – could possibly be an intervention for dementia in older adults.

After completing more than 150 marathons, running coach Jeff Horowitz got sick of running himself ragged with 70 to 100-mile weeks during training.
In order to avoid injury and burnout, he designed a less-is-more, quality over quantity philosophy in his book "Smart Marathon Training." Adapt some of his principles into your triathlon training program.

Knowing how to ride a bike is one thing, but having the ability to comfortably and safely share the road with other cyclists requires another level of skill.
These basic handling techniques will help you enjoy the transition from bike rider to full-blown cyclist, and, as an added bonus, can help save a little time on race day.
Hold a straight line
Whether riding on an open road or in a race, always look over your shoulder before swinging from one side of the road to the other. Before carving through a corner, always check your blind spot, especially in a race since the noise created by fellow cyclists isn’t always enough to alert you of their presence.

The old adage, “all good things in moderation,” may be true, especially when it comes to exercise.
In an article in this month’s Mayo Clinic Proccedings researchers looked at an emerging body of papers that point to the fact that even exercise can have diminishing returns.
The authors surveyed more than 50 different studies that followed athletes who chronically trained and participated in extreme endurance events, such as marathons, ultramarathons, Ironman triathlons, and long-distance bicycle races. The studies found that excessive training and competing can cause cardiovascular damage such as scarring and enlargement of the heart and blood vessels, as well as irregular heart beating.

Did that fartlek workout lead to a major bonk instead of runner’s high? Need a glossary just to understand what we’re talking about? We demystify some of the most common running terms.
Verb: To become utterly exhausted and depleted and unable to keep moving forward at a desired pace. This occurs when your glycogen stores are depleted.
Example: “I didn’t think I’d bonk so hard during the race, but it felt like I hit a brick wall and my legs were made of concrete.”
Noun: A Swedish word that means “speedplay.” A run where you speed up and slow down several different times during the workout. You must keep running during the entire workout for it to be considered a fartlek.

The early childhood years are crucial for learning and development. That should involve a great deal of outdoor physical activity and playtime, but that's not always the case.
Nearly half of 3 to 5 year olds are not taken outdoors by a parent or caregiver every day, according to research presented in the Archives of Pediatrics & Adolescent Medicine this week.
"There's a big room for improvement in how parents prioritize their time and what they're doing in the time they're spending with their pre-school children," said lead study author Dr. Pooja Tandon of Seattle Children's Research Institute.

Police officers who engage in at least 60 seconds of intense physical energy while involved in a combative encounter may suffer memory loss, according to a newly published study in the journal Psychological Science.
Researchers found that officers chasing down a suspect or engaging in a physical altercation with someone can often forget details of the incident, including being unable to identify the suspect from a lineup.
The study's lead author, Dr. Lorraine Hope, University of Portsmouth, United Kingdom, said the study's findings are a "warning" to officers, police chiefs and even the court system.
