Q&A: Does caffeine really improve athletic performance, or do you just feel more alert?

Posted January 24th, 2008 at 10:15 AM by Jeremy Sussman

Section: Nutrition, Supplements, Health & Fitness, Exercise

In endurance events, the first cause of fatigue is loss of muscle sugar, so athletes do whatever they can to preserve sugar levels. Caffeine causes the body to produce large amounts of adrenalin, which causes fat to be released from fat cells and float in the bloodstream.

This extra fat is taken up by the muscles and used for energy, thus preserving the body’s limited stored supply of muscle sugar. When muscles run our of sugar, the athlete requires more oxygen to do the same job, slows down, fatigues earlier, and has difficulty maintaining his performance.

Q&A: Is it true that weight loss during exercise is normal?

Posted December 29th, 2007 at 2:16 PM by Martin Kennedy

Section: Health & Fitness, Injury & Rehab, Exercise

If you weigh yourself before and after an hour or two of exercise, the difference is likely to be fluid loss. However, in events lasting several hours or even several days, measurable fat loss can occur. At a competitive 12-hour indoor stationary bicycle marathon, one athlete took fluids and food throughout the entire competition, and still lost 2.64 pounds (Schweizerische Rundschau für Medizin Praxis, July 2007).

Of this weight loss, 1.98 pounds was due to loss of fat. His calculated muscle weight increased by 1.46 pounds due to damage to the muscle cells, which results in fluid retention in the cells.

If You Don’t Snooze, You Lose: The Importance of Sleep

Posted November 29th, 2007 at 5:00 PM by Lisa Cieplechowicz

Section: Health & Fitness

Sleep - it’s one of our nation’s favorite pastimes. Sometimes nothing feels better than throwing a blanket over yourself, burying your face in your pillow, and settling down for a nice, long slumber. But as enjoyable as this nocturnal activity is, millions of Americans are seriously missing out on the fun.

Over 60 million individuals in our society suffer from some type of sleeping disorder, and more than half of these people are men. Unfortunately, lack of sleep can have a myriad of consequences on our minds and bodies.

Low Blood Sugar Causes Mental Fatigue During Competition

Posted November 23rd, 2007 at 3:45 PM by Martha Jones

Section: Nutrition, Race Prep & Recov, Health & Fitness, Exercise

Athletes can expect to feel fatigued when their blood sugar levels drop. Researchers at Loughborough University, UK showed that athletes who did not take sugar during soccer competition lasting 90 minutes felt more tired, had less competitive desire, and had far lower blood sugar levels than athletes who took a sugared drink every 15 minutes during their game (Scandinavian Journal of Medicine & Science in Sports, October 2007).

Your brain gets more than 98 percent of its energy from sugar in the bloodstream. However there is only enough sugar in the bloodstream to last about three minutes. The liver must constantly release sugar into the bloodstream, but there is only enough sugar in the liver to last eight hours during rest and far less than that during exercise. So athletes who do not take a source of sugar during events lasting more than an hour can suffer the psychological effects of low blood sugar levels what include a mental feeling of fatigue and lowered competitive desire.

Your First Marathon:
You Can Do It!

Posted November 12th, 2007 at 6:30 PM by Andrew Goodman

Section: Running & Training, Injury & Rehab, Motivation, Training Tips, Cross Training, Health & Fitness, Exercise

Completing a marathon puts ordinary runners in the company of elite athletes—finishing a 26.2-mile run is an impressive accomplishment.

But you don’t have to be an elite athlete to join the ranks of marathoners around the world. With dedication and training, most runners can complete a marathon—and then have the satisfaction of being able to say, “A marathon” Yeah, I’ve done that.”

So don’t shy away from a marathon because it seems too hard, too long, too painful. With the right attitude and a good training regimen, it’s just 26.2 miles away.

Longer Lower Legs =
More Efficient Running

Posted October 29th, 2007 at 3:30 PM by Allyson Rosen

Section: News & Results, Running & Training, Health & Fitness, Exercise

People who have longer lower leg lengths (the distance from knee to ankle) will usually have greater endurance during running or walking than those with shorter lower leg lengths.

Researchers at the University of Wisconsin showed that people with longer lower legs use less energy when they run (Journal of Human Evolution, August 2007).

In a previous paper in the same journal, these authors showed that people with longer lower legs are better able to prevent heat build-up, which slows you down and makes you tired. When you exercise, almost 80 percent of the energy that you use to power your muscles is lost as heat.

How To Be An Economical
and Efficient Runner

Posted October 19th, 2007 at 3:26 PM by Lisa Cieplechowicz

Section: Running & Training, Training Tips, Health & Fitness, Exercise

For many runners, scoring a faster running time can be a point of frustration. Though you train regularly and your technique may seem impeccable, sometimes your efforts seem to add up to nothing when it comes to improving your speed. In fact, how fast or slow you run often has a great deal to do with your economy of motion.

Economy of motion is a simple enough concept. It refers to the relationship between how much energy you expend when you run and how fast you go. Typically, the less energy it take you to run a given distance the faster - or more “economical” - you will run. Unfortunately, as the New York Times reports, improving your running economy is one task that’s particularly difficult to accomplish, if possible at all.

Tapering for Athletes and Ordinary Exercisers

Posted October 2nd, 2007 at 10:55 AM by Adam Berger

Section: Running & Training, Training Tips, Health & Fitness, Exercise

Tapering refers to the period just before a major race or game, when an athlete reduces workload to be in peak shape on the day of the competition. Ordinary exercisers can apply this training principle when they plan to enter a local race or charity event.

Top athletes must spend a tremendous amount of time training to be able to compete successfully. Their huge volume of work leaves them near exhaustion and before major competitions, they have to find the best way to reduce fatigue while retaining fitness. Many studies have been done to help athletes and coaches decide on the best strategy.

Researchers at the University of Montreal compiled the results of 27 scientifically acceptable studies. They concluded that the best duration of tapering is two weeks, the optimum training volume reduction is by 40 to 60 percent, and the intensity of workouts should be maintained (Medicine & Science in Sports & Exercise, August 2007).

Training load during taper: Almost all of the studies agree that athletes should reduce the amount of work they do. While each athlete must decide on his optimal reduction, many bicycle racers drop from up to 400 miles a week down to fewer than 200, and many runners drop from above 100 miles to fewer than 40.

Q&A: Will following a low- carbohydrate diet help me run faster?

Posted August 17th, 2007 at 10:30 AM by Martha Jones

Section: Nutrition, Healthy Eating, Race Prep & Recov

There is no evidence that it will. Runners get fuel for their muscles from fat and sugar in muscles, fat and sugar in the bloodstream and, to a lesser degree, from protein. The key to increasing endurance for racing is to store as much sugar in muscles before you race and keep it there as long as possible. Muscle sugar gives you the most energy for the least amount of oxygen.

Restricting carbohydrates does not stimulate muscles to store more sugar (Sports Medicine, April-May 2007). A low carbohydrate diet may impair performance if carried out for extended periods because a runner cannot train on a low- carbohydrate diet.

Preserve muscle sugar for speed and endurance

Posted August 2nd, 2007 at 1:00 PM by Martha Jones

Section: Nutrition, Healthy Eating, Hydration, Race Prep & Recov, Health & Fitness, Exercise

How fast you can move and how long you can exercise intensely depends on the amount of sugar (glycogen) stored in your muscles. The same rule applies in all sports: when muscles run out of their stored sugar supply, they require more oxygen and you have to slow down.

Fluid is less important than muscle sugar because dehydration will not cause you to slow down until your blood volume is reduced. As you lose fluid from sweating, interstitial fluid stored around cells is released into the blood to maintain blood volume. When you compete is sports at a very high intensity, your muscles run out for stored sugar long before your blood volume is reduced, and you slow down from lack of muscle sugar before you slow down from reduced blood volume (Sports Medicine, April- May 2007).
