Here’s another entry in a growing list of studies that suggest that pre-exercise static stretching may hamper athletic performance. This current study, published in the Journal of Strength & Conditioning Research (2010; 24 , 2274–79), included 10 male collegiate athletes who participated in a 60-minute treadmill run on two occasions. One run took place after 16 minutes of static stretching of the major lower-body muscles; before the other run, participants simply sat quietly for 16 minutes.
Endurance events such as marathons and triathlons are gaining popularity as more people recognize the benefits of physical activity. However, physicians at Loyola University Health System have issued a warning for inexperienced female endurance athletes. The physicians are concerned that many women athletes are ill-prepared for these events, which they say can lead to serious health risks like menstrual irregularity, fertility issues, stress fractures and osteoporosis.newsletter_teaser: Endurance events such as marathons and triathlons are gaining popularity as more people recognize the benefits of physical activity.

In 2008, David Rowlands, PhD, senior lecturer with the Institute of Food, Nutrition, and Human Health at Massey University in New Zealand, published a study showing that male cyclists who ingested protein and carbohydrates between intense training bouts gained distinct performance and postexercise recovery advantages over men who fueled only with carbohydrates (Applied Physiology, Nutrition, and Metabolism, 33 , 39–51).
Many parents encourage their children to engage in sports to help improve physical activity levels. However, a recent study suggests that playing on a team may incite poor behavior among boys. The study was presented at the American Public Health Association’s 137th Annual Meeting & Exposition in Philadelphia. The researchers surveyed more than 13,000 U.S. high-school students on topics that included sports participation and risky behaviors. According to the results, team sports participation by boys correlated with higher rates of fighting, drinking and binge drinking.

Engaging in team sports may help high-school students lead more active lifestyles. But depending on the sport, your teen may also be at greater risk for injury. Of all high-school sports, football and wrestling are the most injurious, according to recent
research. In a first-of-its-kind study, published in the
September issue of the American Journal of Sports Medicine (2009;
37 , 1798–1805), scientists examined severe injuries among students from 2005 to 2007.
All the time, I hear fitness professionals tell their clients not to exercise above a certain heart rate, as if it were bad for people to run or bike fast. Target heart rate has become a buzz phrase. Even many cardio machines display a “fat-burning zone” on their panels, encouraging people to exercise in a specific heart rate range. Have you ever wondered if your clients really have to exercise in a specific heart rate zone to lose fat? And what happens if they venture out of that zone?
It’s not just the ranks of older Americans that are swelling: the number of seniors who are physically active is also going through the roof. Now, more than ever, your older clients are participating in races and vigorous fitness classes—and
a percentage may even make it to the Senior Olympics.
There are more than 300 marathons just in the United States each year, with hundreds of thousands of people running them. Chances are that one or two of your clients want to do one. So how do you train them for a marathon? Consider the following strategy.
