When I wrote my best-selling Sportsmedicine Book in 1978, I coined the term RICE (Rest, Ice, Compression, Elevation) for the treatment of athletic injuries (Little Brown and Co., page 94). Ice has been a standard treatment for injuries and sore muscles because it helps to relieve pain caused by injured tissue. Coaches have used my "RICE" guideline for decades, but now it appears that both Ice and complete Rest may delay healing, instead of helping.
The old guideline recommending 30 minutes of exercise three times a week just isn't enough, according to the latest research. Athletes know that they need to work out every day, and all people who just want to stay healthy can benefit from the same type of exercise program.
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.
During the cold winter months when snow and ice are on the ground, it's too dangerous to ride a bike, so many cyclists run instead. The standard comparison is that one mile of running equals four miles of cycling, but that's lousy science. Although running requires the same amount of energy per mile at any speed (110 calories per mile) , riding is affected by wind resistance so the faster you ride, the more energy you use. So you have to compare running and cycling at different cycling speeds.
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.
1. People need to learn a correct range of motion for each exercise that is within their capability and practice that with lighter resistance. 2. There is not a lot of convincing data on repetition duration, but what there is including work we have done here, suggests for each exercise taking about three seconds for the concentric part of the rep, and three seconds for the eccentric part.
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.
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.
Two exciting new studies show that older men and women who have cycled for many years do not have the markers of aging found in non-exercising people. Their muscle size and strength, amount of body fat, levels of hormones such as testosterone, and blood cholesterol levels were close to those of much younger people.
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.
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
Most competitive bodybuilders spend hours trying to do many sets over and over again. You don't need to do that. Various studies show that you can gain up to 80 percent of your maximum strength by picking out four to eight specific lifts, lifting one set of ten of the heaviest weight in each, and repeating your program two or three times a week.
VO2max can be used to predict a person’s risk of premature death from a heart attack. Researchers at the Norwegian University of Science and Technology have developed a simple way to estimate a person’s VO2max, his maximal ability to take in and use oxygen.
To preserve muscle and bone size and strength, recreational runners and cyclists should do upper body and core weight lifting and resistance training. Everybody will lose muscle and bone size and strength with aging. Your bones weaken progressively after age 30, and between ages 35 and 50, about 28 percent of North American men and women suffer from bone weakening called osteopenia.
Just about everyone with an unobstructed nose will breathe through their nose when at rest or during casual activities, but most people will breathe through their mouth during exercise. The more intensely you exercise, the more likely that you will have to breathe through your mouth because you may not be able to get enough air through your nose to feel comfortable back of your mouth.
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
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.
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.
If you want to make a muscle stronger, you have to exercise it intensely enough to damage the muscle fibers and when they heal, they will be stronger than they were. You can tell you are causing muscle damage because of the burning you will feel during exercise and the soreness in that muscle you feel four to eight hours later.
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.
"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.
A recent study used accelerometers to measure the physical activity of more than 90,000 healthy people for seven days in 2015, and then followed them to 2020. The more and harder they exercised, the less likely they were to suffer heart disease (PLOS Medicine, January 12, 2021). There was no maximum amount of exercise that increased risk for heart attacks or heart disease.
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.
A new study suggests that it is the level of fitness, not time spent sitting, that predicts susceptibility to disease and longevity.
