Have you wondered whether you burn more calories when you run or when you ride a bicycle? Running requires the same amount of energy per mile at any speed, but cycling is slowed so much by wind resistance that the faster you ride, the harder you have to pedal and more energy you use.
Committed exercisers should try to continue to exercise during this COVID-19 pandemic, but they should realize that both too much exercise and exercising while sick increase risk for medical complications, such as irregular heartbeats, and death
Sleeping can help to prevent exercise injuries. Healthy U.S. soldiers in training are less likely to suffer exercise-related injuries such as fractures, sprains and muscle strains when they sleep at least eight hours at night.
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
Fifty-two percent of North Americans spend $41 billion a year on over-the-counter food supplements. Athletes and exercisers spend more than 14 percent of the $41 billion, or $5.67 billion, for supplements that are supposed to make them faster or stronger.
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.
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.
Scientific American has a fascinating article that explains why you should exercise your brain while you exercise your body. There is evidence that you may be able to make You can make new brain cells as you age by exercising your skeletal muscles and brain at the same time
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.
If you feel discomfort or pain in the skin of your feet while you are exercising, stop exercising immediately and correct the problem. Continuously rubbing your skin can cause very painful blisters that can break and leave you with open painful areas for many weeks.
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.
If you want to become stronger and faster and have greater endurance, you need to exercise so intensely on one day that you damage your muscles and feel sore on the next day and then train at a reduced intensity for as many days as it takes for your muscles to heal and the soreness to lessen. Then you take your next intense workout.
Researchers reviewed eight studies that used accelerometers to follow 36,383 adults, 40 years of age and older, for six years. They found that exercising regularly, regardless of intensity, was associated with reduced risk for death during the study period, while sitting for more than nine hours a day was associated with increased risk of death.
Research evidence shows that exercise strengthens the heart, prevents and treats heart attacks and strokes, and prolongs lives (Circulation, 2018;137(18):1896-1898). The more frequently people exercise, the less likely they are to die of heart disease (JACC Cardiovasc Imaging, 2017;10:1461-1468), but there is some evidence that a person can increase heart attack risk by exercising...
I predict that in the next few years, virtually all cyclists will have motors on their bikes. I think that you can get a better training effect with a motor than without it. Anyone who has difficulty accelerating a bike will benefit from an added boost from an electric motor.
Athletes and serious exercisers can get into an overtraining syndrome in which they become injured or suffer frequent infections, feel exhausted, don't perform up to their usual levels, and even lose interest in training. One of the most difficult problems for athletes is knowing when they are training too much. You make a muscle stronger...
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
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.
People who want to grow larger muscles spend more than 10 million dollars a year on whey protein shakes. A new study on mice shows that these whey protein shakes contain very high levels of branched-chain amino acids (BCAAs), which can reduce certain brain hormones to increase risk for obesity and premature death.
The more intensely you exercise, the less likely you are to suffer a heart attack, even though heart attacks can be caused by intense exercise in some people who already have irregular heartbeats or blocked arteries leading to their hearts.
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.
A recent study shows that people who use high-intensity interval training (HIIT) are far more likely to become injured than people who use less intense exercise and that the highest injury rate from interval training is in men at ages 20 to 39, the ages when they are at their highest potential to be at their best competitive level to become champion athletes.
If you are an exerciser and develop a sharp pain on a bone that hurts when you press directly on that spot and does not hurt to touch an inch away, you probably have a stress fracture. Stress fractures are very common injuries, particularly in runners.
Aging causes you to lose strength, no matter how much you exercise. Muscles are made up of hundreds of thousands of individual fibers, like a rope is made up of many strands. Each muscle fiber is innervated by a single motor nerve. With aging you lose motor nerves, and with each loss of a nerve, you also lose the corresponding muscle fiber that it innervates.
