Chronic foot, leg and knee pain during running can be caused by the foot hitting the ground with excessive force and excessive rolling in of the feet after they hit the ground. These problems can often be alleviated just by taking shorter strides to reduce the force of the foot hitting the ground, and putting special inserts called orthotics in your shoes
The best way to train for skiing is to ski, but snow isn’t always available. To prepare for a skiing trip, you need to strengthen both your heart muscles and your skeletal muscles. You can strengthen your heart for skiing with any exercise that will raise your heart rate for at least 10 minutes, at least three times a week.
A positive outcome of the many COVID-19 restrictions has been a huge boom in bicycling. If you are a regular cyclist or are new to the sport, be proud. Humans riding on bicycles are more energy-efficient than any other form of transportation and any other animal. Vance Tucker of Duke University compared bicyclists to people and animals running, birds flying and fish swimming, as well as to people in motor-powered cars, boats, trains and planes
A recent review of 22 scientific studies shows that adding a resistance program such as lifting weights to endurance sports such as running or cycling can increase muscle size and strength, with greater benefit from low volume, high-resistance weight lifting than high volume, lower-resistance exercise.
In the largest study so far of accelerometer-measured physical activity, 96,476 healthy men and women in Great Britain (mean age 62 years) wore wrist accelerometers for one week and were then followed for an average of 3.1 years. The people who were more active had a lower risk of dying, and adding intensity to their exercise increased that protection.
A study from Harvard Medical School shows that a high rise in blood sugar after meals can limit increases in your ability to take in and use oxygen during exercise. This means that if your diet causes high blood sugar levels when you eat, you lose one of the major health benefits of exercise.
Restricting carbohydrates with a keto diet or fasting will tire you earlier when you exercise. Many studies show that low-carbohydrate diets impair performance in sports that require speed. On a low-carbohydrate diet, you can't train very fast and you can't move as fast in races.
Resistance exercise is the best way to slow down the loss of muscle strength that occurs with aging, and I believe that everyone should do some type of resistance exercise (moving your muscles against an opposing force) as part of their regular exercise program.
An interesting study showed that after finishing the 26-mile Boston Marathon, runners had changes in the bacteria in their colons that may have helped them to run faster and longer.
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
When you contract your skeletal muscles, they squeeze the veins near them to pump extra blood back to your heart. The extra blood flowing back to your heart fills up your heart, which stretches your heart muscle, causing the heart muscle to contract with greater force and pump more blood back your body.
The problem with wearing masks when you exercise outdoors is that they can limit your ability to breathe. This may not be an issue if you are doing casual exercise, but if you are running or cycling vigorously, you will probably find yourself gasping for air.
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.
Always try to keep at least a slight bend in your knee when you run or bike. When you run, you are supposed to land on each foot with a partially-bent knee. Otherwise you transmit the shock of your foot hitting the ground directly onto your knees, hips and back. Straightening your knees when you pedal markedly increases risk for knee pain by increasing the force on your joints.
It's normal to sweat more after you finish exercising than you do while you exercise. Your body temperature varies throughout the day, going from around 97 degrees in the early morning to about 99 degrees in the early evening. Exercise raises body temperature considerably.
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.
A resistance exercise program can help to slow the loss of muscle fibers and improve mobility as people age. Lifting weights or using Nautilus-type resistance training machines will strengthen your skeletal muscles, help to prevent broken bones from falls, and make your heart stronger to reduce risk of heart failure.
The American Heart Association has cautioned that, "Exercise, particularly when performed by unfit individuals, can acutely increase the risk of sudden cardiac death and acute myocardial infarction in susceptible people." However, a recent review of 48 research articles found no reduction in lifespan, no matter how much a person exercises
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.
