Study: Fewer Intense Workouts, More Recovery for Maximum Performance

How much time should you spend working at your maximum level in your sport, compared to miles or days spent going at a relaxed pace?

Researchers at the University of Madrid in Spain divided competitive distance runners into two groups. One group did frequent intense workouts and fewer slow recovery miles, while the second group did fewer intense workouts and more slow miles (Journal of Strength and Conditioning Research, August 2007).

At the end of five months, the runners who did fewer intense workouts and more recovery miles improved far more than those who ran fewer miles and spent a lot of their time trying to run very fast.

HIIT: The Ultimate Workout

Posted November 27th, 2007 at 5:45 PM by Shannon Clark

If you aren’t a stranger to the gym, you’ve likely already heard of something called high intensity interval training (HIIT). Whether it was between two trainers discussing their training techniques or someone complaining about the brutality of the workout, it may be something you’ve avoided up until now.

There is no doubt that high intensity interval training (HIIT) is something that will give you a run for your money. It definitely is not - by any means - easy, but it will get you results.

Not only is it more conducive to retaining your current muscle mass then longer cardio sessions, but it is also far better (in most cases) in terms of promoting fat loss and increasing the metabolism. The thing about HIIT is that it does not expend an extremely large amount of calories while you are performing it.

Low Blood Sugar Causes Mental Fatigue During Competition

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.

Interval Training on Consecutive Days

Posted October 15th, 2007 at 11:45 AM by Martha Jones

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

The faster an athlete moves in training, the faster he or she will be able to move during competition. So athletes use a training technique called interval training in which they run, cycle, skate, ski or swim very fast for a short time. When they become severely short of breath, they slow down until they recover, and then move very fast again.

Researchers at Ithaca College showed that athletes can gain as much by doing this type of intense interval training on consecutive days as on alternate days (Medicine & Science in Sports & Exercise, September 2007).

Interval training causes considerable muscle damage, so it usually leaves athletes sore the next day. Most trainers recommend exercising at a slower pace until the soreness disappears. That is why athletes usually follow each intense day with one or more easy days.

However, many competitions require an athlete to exercise flat out for several consecutive days. He/She may have to compete in multiple preliminary heats over several consecutive days to reach the finals.

Understanding the
Need For Sleep

Posted September 27th, 2007 at 3:00 PM by Lisa Cieplechowicz

Section: Health & Fitness, Exercise

Most athletes know all too well the intense feelings of fatigue and exhaustion that tend to follow intense workouts and training sessions. Frequent naps and long-night sleeps become common for the individual used to pushing their body to perform physical feats. But why exactly is it that strenuous workouts lead to such drowsiness while other forms of exercise can actually help boost our energy levels?

According to a recent article from The New York Times, this is one issue that is still unresolved. Though much research has been dedicated to the topic of sleep, there is a significant lack of studies on the effect intense exercise such as endurance running can have on an individual’s sleeping patterns.

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).

Endurance training techniques for runners of all levels

Posted January 5th, 2007 at 12:00 PM by Emily Hoskins

Section: Running & Training, Training Tips

Unlike many recreational activities, training for a marathon is serious business. If you fail to train properly you not only run the risk of not finishing, but you could seriously injure yourself.

There are several types of endurance training out there, so finding the right one for your personal goals and needs is crucial. The types of aerobic endurance training differ in duration, frequency, and intensity which will lead to different physiological adaptations within the body that improve your overall fitness level.

Do Protein Drinks Increase Speed During Competition?

Posted October 23rd, 2006 at 6:06 AM by Jeanie Rebb

Section: Running & Training, Nutrition, Supplements, Health & Fitness

Adding protein to a sports drink does not help athletes cycle faster in a 50-mile time trial, according to a study from McMaster University in Ontario (Medicine and Science in Sports and Exercise, August, 2006).

Many studies show that taking in a carbohydrate drink helps improve performances in athletic events lasting more than an hour. Two recent studies showed that adding protein to a carbohydrate drink improves performance even more.

However, in these studies, cyclists worked at a fixed rate of effort, rather than using spurts of energy as athletes do in competition.

When you compete in an athletic event lasting more than an hour, you need fluids and calories. In events lasting more than three hours, you also need salt. Calories come from carbohydrates, fats, and proteins.

During highly-intense exercise, your muscles use carbohydrates more efficiently than proteins or fats. So carbohydrates are the calorie source of choice during intense exercise.
