When you run very fast, you reach a point where you gasp for breath. You keep on pushing the pace and after a few seconds, you feel that you have recovered and that you can pick up the pace again. It’s called second wind and your apparent recovery is caused by lactic acid.
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.
All maximum heart rate formulae are based on averages. They can be used to help you plan and monitor your exercise program, but they should not be interpreted as absolute limits or goals. Your maximum heart rate may differ from these averages. Whether you are a competitive athlete or an ordinary exerciser, you really do not need a heart rate monitor.
You can expect to lose muscle size and strength as you age. Between 40 and 50 years of age, you lose more than eight percent of your muscle size. This loss increases to 15 percent per decade after age 75. The people who lose the most muscle usually are the least active, exercise the least and are the ones who die earliest.
Most bicycle shops are now selling motor-driven bicycles, which can be an ideal solution for a person who is out of shape or just not strong enough to ride a regular bike. Motor-driven stationary bicycles make it possible for just about anyone to gain the benefits of an exercise program, even those with severe disabilities.
Can you become very strong by doing isometric exercises in which you push against something that doesn't move, such as a wall? The single stimulus to make a muscle stronger is to exercise a muscle against a resistance; therefore, you can become strong by doing isometric exercises. However, there are two drawbacks: isometrics can...
Many studies show that you can exercise longer and more intensely and recover faster when you take a source of sugar during vigorous exercise. Dozens of brands of sports drinks are promoted to fill this need, but a new study from Appalachian State University shows that a banana appears to offer superior results, specifically helping athletes to recover faster from intense exercise.
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.
Advertisements on television claim that you can wrap a special belt around your belly, plug it into an electric outlet, turn on the electricity, and then watch your belly muscles contract to give you rock-hard belly muscles. You can bet that the beautiful people who demonstrate the machines on television didn't get their belly muscles...
Don't believe that you can gain the benefits of exercise without exercising. Many products are promoted to give people bigger muscles and make them better athletes, as well as to help them lose weight and prevent diabetes and heart attacks. They are sold to unsuspecting consumers without needing prescriptions. These products are not approved by the Food and Drug Administration and are likely to be ineffective or even harmful.
Eating during and after long, intense workouts helps competitive athletes recover faster from their workouts and therefore helps to make them stronger and faster. It is the intense workout that makes you stronger and faster, so the more rapidly you recover from an intense workout, the sooner you can take your next intense workout and the more improvement you will gain.
A study from Imperial College in London shows that increased use of helmets by bicycle riders has markedly reduced head injuries (1). Do you know why woodpeckers don't damage their brains when they peck on wood? Their skulls fit so tightly that they don't allow the brain to move inside. Human skulls are enclosed...
On January 4, 2017, 105-year-old Robert Marchand rode his bicycle 14.01 miles to set the world record for his age for the one-hour ride. He rode 92 laps at the Velodrome National near Paris and as he completed his ride, the fans gave him a standing ovation, chanting "Robert, Robert" while dozens of TV crews and cameramen captured the moment.
Taking extra fat during long distance running or cycling races will not help you to go faster or win the race. When you exercise intensely, your muscles burn mostly sugar and the more intensely you race, the greater the percentage of sugar that your muscles use.
It's healthy to exercise and harmful to breathe polluted air. Many people wonder if they will do more harm than good by exercising on days when the air is heavily polluted. The worst time for pollution is when clouds cover the sky and automobiles fill the roads. Automobile exhaust fumes are the principal source of...
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.
Three new studies help us understand the many good things that exercise does for your brain. The first study shows that a regular exercise program alters blood flow to the brain to improve mental function in older people who suffer from mild cognitive impairment that often precedes dementia. The second study shows that exercise can improve thinking skills in people of all ages. The third study shows that exercise-induced muscle changes may help to boost mood in older adults
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.
You'll see lots of exercise programs, devices and machines in television commercials that claim to get rid of fat from your belly. While they can strengthen your belly muscles, there is no such thing as spot reduction. When you take in more calories than your body burns, you store them as fat. Some people...
People who lie in bed without moving day after day suffer progressive weakening of their heart muscle. Eventually the heart becomes too weak to pump enough oxygen to the brain, they stop breathing and die from heart failure. A recent study on mice shows how this is likely to happen.
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.
"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.
Will training for a triathalon make you a better cyclist? World-class triathletes are slower runners, swimmers and cyclists than athletes who compete in only one sport. A study from the University of Toulon-Var in France shows that swimming before cycling slows you down (Canadian Journal of Applied Physiology, August 2005). Well-trained male triathletes pedaled...
A heart attack is caused by lack of oxygen. Anything that increases the supply of oxygen to the heart markedly reduces risk for suffering a heart attack, improves a heart attack victim’s chances of surviving a heart attack and of not having another heart attack, and makes him or her able to be far...
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.
The huge number of mitochondria in dogs' muscles explains why sled dogs can run more than 100 miles a day, at sub-8-minute-mile pace for weeks on end, while humans could not possibly run as long or as fast and recover from such abuse of their muscles.
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
A 28-year-old woman collapsed and died after finishing the Boston Marathon. Her blood salt levels were extremely low and she died from a condition called hyponatremia. A few weeks ago, a policeman training for bicycle duty died of the same condition. On July 26, 2005, sports medicine experts issued a warning to all athletes from the First International Exercise-Associated Hyponatremia Consensus Development Conference.
