"Carbohydrate loading" the night before a big race can harm your performance and your health. More than forty years ago, I reported the case of a marathon runner who had a heart attack after carbohydrate loading in the Journal of the American Medical Association.
Everyone should try to keep on moving their muscles every day. Sitting around for long periods of time can cause you to become diabetic and increase your risk for a heart attack, and lying in bed for long periods puts you at increased risk for heart failure and premature death
To make muscles stronger, you need to exercise intensely enough to damage the muscles. You can tell that you are damaging muscles when you exercise vigorously enough to feel soreness in those muscles eight to 24 hours later, which is called Delayed Onset Muscle Soreness or DOMS.
Some athletes and exercisers take pain medication (aspirin or NSAIDs) because they think it may prevent muscle soreness or will help them to heal faster after a workout. However, taking pain medicines before or during exercise will not block pain, help you to exercise longer or recover faster from exercise.
Your maximum heart rate is the fastest your heart can beat and still pump blood effectively through your body. As you age, your maximum heart rate drops. The maximum heart rate formulae used by heart rate monitors (such as MAXIMUM HEART RATE = 220 – age) are all based on averages. They can be used to help you plan your exercise program, but they should not be interpreted as absolute limits or goals.
A recent study from New Zealand compared the effects of prolonged sitting, prolonged standing or taking regular activity breaks on blood flow and insulin levels. We know from earlier studies that prolonged sitting increases risk for forming clots, but this new study suggests that people with jobs that require them to stand for long periods may be even worse off.
Creatine is a substance found in muscle cells that helps your muscles produce energy, particularly while lifting heavy weights or exercising intensely. Your body makes creatine from three amino acids (protein building blocks) called L-arginine, glycine, and L-methionine. You also get creatine when you eat animal protein: meat, poultry or seafood.
The American College of Sports Medicine (ACSM) surveyed more than 4,000 fitness professionals and found that High Intensity Interval Training (HIIT) is the most popular trend in fitness for 2018. All healthy people can benefit from some form of interval training. They can pick up the pace for a few seconds while walking, running, cycling, swimming, skiing or skating, and then slow down when they feel the least discomfort.
Muscle cramps occur most often at night when you are sleeping, but they also can occur when you exercise vigorously, tear a muscle, or keep one leg in an awkward position, such as sitting in a chair in the same position for a long time. Muscle cramps are classified into those that occur during exercise and those that can occur at any time not related to exercise, usually at night.
Many studies show that exercise helps to prevent heart attacks, and it may do so by changing the bacteria in your colon. A recent study from Finland shows that exercising for just six weeks can increase healthful anti-inflammatory bacteria in your colon.
Healthy and fit people usually don't need to eat during a ride when they cycle at a casual pace for less than two hours. However, you can prolong your endurance for a hard ride by taking a source of sugar when you ride very hard for more than an hour, and a source of salt when you ride for more than three hours.
The most common cause of knee pain in bicycle riders is having the seat set so high that it forces you to fully straighten the knee as the pedal reaches its lowest level. You are never supposed to fully straighten your knee when you do any kind of exercise, particularly cycling or running.
A new study suggests that it is the level of fitness, not time spent sitting, that predicts susceptibility to disease and longevity.
If you want to become fit and use exercise to help prevent a heart attack, first check with your doctor to make sure that you do not have anything wrong with your heart or blood vessels. Intense exercise can increase your risk for a heart attack if you already have a damaged heart.
If you don't exercise regularly and vigorously, expect to lose a significant amount of muscle strength as you age, and expect that loss of strength to reduce the quality of your life. A 15-year follow-up study showed that older people who lift weights at least twice a week had a 46 percent lower death rate within the study period.
With aging you can expect to lose muscle size and strength, which increases risk for lifestyle diseases and disabilities. Progressive loss of muscle starts at about 25 years of age. It is caused mainly by a loss of muscle fibers and to a lesser extent by a reduction in type 2 strength fast twitch fibers.
Interval training means that you alternate bursts of intense exercise with slow exercise until you feel tired. Short intervals are defined as lasting less than 30 seconds each, while long intervals usually last more than two minutes each. The most efficient, time-saving and health-benefiting way to exercise is to use short intervals
Cycling is a power sport. The stronger you are, the faster you can go on a bike. Power = [force that your feet apply to the pedals] x [cadence, or how fast you spin your pedals]. Cadence is the number of pedal revolutions per minute (RPMs). Fatigue for a bicycle rider comes primarily from how hard you press on the pedals, not how fast you turn them.
Mary Cain was unbeatable in high school races. At age 16, she became the youngest athlete ever to represent the U.S at a World Championship track meet, and at age 17, she was the 2014 World Junior Champion in the 3000 meter run.
Up to 70 percent of North Americans adults will develop diabetes or pre-diabetes, usually from insulin resistance caused by excess fat in the liver and muscles. Exercise helps to empty fat from the liver and muscles, so exercise helps to prevent and treat diabetes.
I have often recommended that exercisers take a sugared, caffeinated soft drink for a performance boost during prolonged vigorous exercise. I still think this is good advice, but people who are exercising at a casual pace for an extended time may want to restrict their intake of soft drinks
The training principles that improve performance in competitive athletes can be used by all exercisers, even those who have never exercised previously, and can help to prevent heart attacks and prolong lives. Exercise helps to prevent heart attacks because exercise makes muscles stronger, including your heart muscle.
Many exercise programs and tests used to measure heart function are based on an unreliable MAXIMUM HEART RATE formula that predicts the fastest your heart can beat and still pump blood through your body. Although this formula is the golden standard used today, it is not based on science.
