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
Most running injuries are caused by the high impact of your foot hitting the ground, which is determined most by the length of person's natural stride. Unnecessarily high impact can be caused by over-striding. Contrary to common belief, it is not important whether you land on the front of your foot or the heel.
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.
Exercise is now recommended as part of the treatment for cancer by the American College of Sports Medicine, American Society of Clinical Oncology, National Comprehensive Cancer Network, American Cancer Society, Oncology Nursing Society, the Commission on Cancer, and the Cancer Foundation For Life. A regular exercise program reduces carcinogenic inflammation, strengthens the immune system, and improves mental processing by lowering cancer-inducing insulin-like growth factor 1, DNA damage and gene mutations, and increasing apoptosis.
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.
Several recent studies show that exercise helps to prolong your life by strengthening heart muscle, increasing the ability of the heart to pump increased amounts of oxygen through the body, reducing belly fat, and increasing the diversity of bacteria in your colon.
If you want to improve your level of fitness, you can try interval training, the technique used by athletes in sports requiring speed and endurance such as cycling, skiing, running or swimming. They exercise very intensely, rest, and then alternate intense bursts of exercise and rest until their muscles start to feel heavy or tired.
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
"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.
Do you believe ads that claim oxygenated water cures tiredness, improves memory, prevents diseases, treats lung disease, helps you to exercise longer and makes you a better athlete? These and all of their other claims are not supported by scientific evidence. Lungs are the only organ humans have to provide adequate oxygen to the bloodstream. Water is not broken down into hydrogen and oxygen in your digestive tract; it is absorbed, used and excreted as water.
Pablo Cassals, Nadia Boulanger, Arturo Toscanini, Arthur Rubinstein and Paul Paray all conducted major orchestras into their nineties, and Walter Demrosch, Arthur Fiedler, Serge Kousevitsky, Leopold Stokowski, Sir Thomas Beecham and Eugene Ormandy conducted into their eighties. The constant exercise involved in the act of conducting may be a strong part of the reason for their long lives.
Some athletes and exercisers use pain medication, such as ibuprofin (Advil, Motrin) and other non-steroidal anti-inflammatory drugs (NSAIDs), because they think it will help them to recover faster from muscle soreness so they will be able to do more training and become better athletes. NSAIDs do not prevent DOMS (Delayed Onset Muscle Soreness).
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.
Athletes use interval training to make themselves faster and stronger, and everyone with a healthy heart can benefit from this technique. A typical interval workout for non-competitive exercisers would be a session of jogging, walking or cycling in which they sarm up by moving slowly for about 10 minutes, pick up the pace until they feel a slight burning in their muscles (this usually takes 10-20 seconds), slow down as soon as they feel this muscle burning, and go slowly until the burning is gone and breathing is back to normal.
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.
"Cooling down" means that after you exercise intensely, you slow down and exercise at low intensity for a while before you stop exercising for that session. The scientific literature is controversial on whether cooling down helps to reduce next-day muscle soreness to help muscles to recover faster.
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.
The same training principles that improve athletic performance in competitive athletes also help to prevent heart attacks and prolong lives. The SUN Study on 18,737 middle-aged people showed that those who exercise intensely have half the rate of heart attacks as those who do the same amount of exercise less intensely.
A study of 798 asymptomatic and apparently healthy master athletes (runners, cyclists, triathletes, rowers and hockey players), 35+ years old, who exercised fairly vigorously 3-7 days a week, found that 10 percent had greater than 70 percent blockage of the arteries leading to their hearts. Exercise helps to prevent heart attacks, but exercise does not prevent plaques from forming in arteries.
Studies in the new field of Epigenetics are showing that lifestyle factors can change the way your body responds to your genes. In one of these studies, researchers were delighted to find a set of identical twins with vastly different lifestyles. They found that a lifetime of exercise is likely to give you the body characteristics of a healthy athlete, while an inactive lifestyle can give you body characteristics associated with increased risk for many diseases.
Many studies show that having excess fat in your belly is associated with increased risk for dementia, but a new study shows that as a person ages, lack of muscle size and strength appears to be an even stronger predictor of dementia than having excess belly fat.
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.
