  • Consider An Exercise Stress Test

    Fitness

    An exercise stress test measures the heart’s response to physical exertion and can give your doctor an idea of how safe it would be for you to exercise and at what intensity you can exercise with relative safety. If you undergo an exercise test, your doctor will ask you to either pedal a stationary bike or walk on a motorized treadmill that increases in speed or grade. Electrodes placed on your chest will monitor your heart activity. Your blood pressure will be monitored, too.

    Should you have an exercise stress test? According to the National Heart, Lung, and Blood Institute, exercise stress testing isn’t routinely done to screen for problems, such as coronary artery disease (CAD). Usually, you will have to have symptoms of CAD before a doctor recommends exercise stress testing.

    You should check with your doctor about the need for an exercise stress test. In general you may be advised to have an exercise stress test if:

    *  You plan to start a vigorous exercise program and you are a male over the age of 45 or a female over the age of 55, especially if you have:

    – Diabetes or kidney disease.

    – Very high blood pressure.

    – Very high LDL (bad) blood cholesterol.

    – A family history of heart disease or many risk factors for it.

    *  You have chest pain during physical activity.

    *  You have a diagnosed heart ailment, lung disease, or metabolic disorder.

    *  You feel faint, get a rapid heartbeat, or feel a fluttering feeling in your chest when you exercise.

    *  You get short of breath at rest or when you exercise.

    *  You have had an abnormal resting electrocardiogram (ECG).

  • Consider Low-Impact Or Nonimpact Aerobics

    Fitness

    Image of man exercising at the gym.

    Fitness activities that involve steady, rhythmic motions of major muscle groups and burn oxygen for more than a brief spurt are considered aerobic. They force your heart and lungs to work at anywhere from 60 to 85 percent of their capacity. Brisk walking and bicycling are examples of aerobic activities. So is aerobic dance-informally choreographed routines that combine calisthenics and dance.

    Aerobic dance classes became the rage in the early 1980s, but shock to bones and tendons caused by repeated jumping and bouncing produced a number of injuries. Low-impact and nonimpact aerobics are kinder to your skeleton.

    Low-impact aerobics are designed so that:

    *  Your feet stay close to the floor, and only one foot leaves the floor at a time.

    *  Only moderate jumping is involved.

    *  Jerky movements are kept to a minimum.

    Nonimpact aerobics are designed so that:

    *  No jumping is involved.

    *  They rely on large muscles of the thighs (as in lifts) rather than muscles in the feet and calves (as in jogging and skipping in place).

    *  They require more arm movement than high-intensity aerobics.

  • How To Buy Sports Shoes That Fit

    Fitness

    Image of person lacing tennis shoe.

    A carpenter needs a saw, a painter needs a brush, and an accountant needs a calculator. And anyone who’s serious about fitness needs a good pair of shoes (or several, if you’re active in more than one activity besides swimming). The right shoes can make the difference between comfort and discomfort, between safety and injury, between performing well and not performing well.

    Consider these factors before you buy activewear shoes.

    *  Are the shoes suitable for the sport or activity for which you intend to wear them? Walking, hiking, racquetball, tennis, aerobics, and so forth require differently designed footwear. But you may want to consider cross-training shoes, suitable for several different activities.

    *  Can you wiggle your toes in the shoes while sitting and standing? (You should be able to.)

    *  Does the widest area of your foot correspond to the widest area of the shoe? (To find out, try this: Stand on a piece of paper, bend down, and trace a line around each shoe with a pencil. Then slip off your shoes, stand in the same place, and trace a line around each foot with a different colored pencil. If at any point the outline of your feet is larger than the outline of your shoes, you’re squeezing some or all of the bones, ligaments and muscles in each foot.)

    *  Do the inner seams rub against your foot? (They shouldn’t.)

    *  Does the shoe have a firm heel cradle and arch support?

    *  Does the shoe provide adequate shock absorption?

    *  Are the shoes comfortable when you move from side to side or when you walk or jump? Test these movements before you buy.

    Good shoes don’t need to be “broken in.” The shoes you buy should be comfortable from the start.

  • Hydrate To Feel Great

    Fitness

    Drink fluids before, during, and after exercising.

    How much water and other fluids do you need?

    To stay hydrated, your needs vary and depend on:

    *  How hard you exercise

    *  How long you exercise

    *  The temperature and humidity

    *  How much you sweat and how much weight you lose from sweat

    Know the signs of dehydration:

    *  Severe thirst (sometimes)

    *  Headache

    *  Weakness

    *  Muscle cramps

    *  Dry mouth and eyes. Sweating may stop.

    *  Nausea

    With severe dehydration, you may also feel very weak, confused, dizzy, or lightheaded. These symptoms require emergency medical care.

    Action Step

    To keep from getting dehydrated, drink water throughout the day. Drink sports beverages if you sweat a lot. Limit coffee, tea, and colas. Don’t rely on thirst alone to tell you if your body needs more fluid.

  • Rate Your Aerobics Class

    Fitness

    Image of an aerobic class.

    Use this handy ten-point checklist to figure out whether an aerobics class is right for you. (You may have to take a class or two on a trial basis to answer all the questions.)

    1.  Is the instructor well-qualified? (He or she should be certified by the American College of Sports Medicine or by a national aerobics association.)

    2.  Is the floor firm yet resilient? (It should be made of either wood, with an airspace or a spring cushion underneath, or polyvinylchloride / urethane. Avoid mats. They can throw you off balance.)

    3.  Is the room air-conditioned?

    4.  Is there enough space for each participant to move freely, without crowding?

    5.  Does the routine include a warm-up and cool-down period?

    6.  Does the aerobic portion of the class last at least 20 minutes? (Your heart rate should reach but not exceed your target heart rate.)

    7.  Are you told how to check your pulse before, during, and after the aerobic portion of the class?

    8.  Does the routine allow participants to adjust the pace to their individual ability? (You should be able to step up the pace or ease off if you need to.)

    9.  Does the instructor introduce new routines or music from time to time?

    10. Do you feel relaxed or invigorated after class? If you feel sore and exhausted, something’s wrong.

    “Yes” answers mean you’ve probably found a class that will suit your needs.

  • Bike Safety

    BE FIT

    Bike up against a yellow wall.

    Bike sales have increased during the COVID-19 pandemic. Bicycling is great exercise! However, it’s important to keep yourself safe while on two wheels. Collisions can and do occur, and some can be serious.

    To minimize your risk of injury while riding a bicycle:

    *Wear a helmet.Studies show that a helmet lowers your risk of serious head and brain injuries by 85%. Make sure it is snug on your head. It should have a chin strap that stays in place.

    *Ride right.Use the right shoulder of the road and follow traffic signs and signals. Signal your turns with your arm so drivers know what you’re doing.

    *Use a bike lane if there is one.If not, try to choose wide roads with less traffic and lower speed limits. When a lane is too narrow for a car and bike to safely ride side by side, you will need to ride toward the middle of the road.

    *Be aware.Sometimes drivers don’t see you. Be careful at intersections and when riding next to parked cars and in parking lots.

    *Don’t use headphones.It’s important to be able to hear cars coming from behind you so you can react safely and move over if needed.

    *Wear bright colors and use reflectors.This will make it easier for drivers to see you.

    *Don’t ride.It is dangerous to cycle if you’ve been drinking alcohol or using drugs.

    *Cover your toes.Don’t wear sandals or flip flops while riding.

    *Bring water.Most bikes have a water bottle holder. Drink often to avoid dehydration, especially on longer rides.

    *Keep kids safe.Children should not ride on roads with traffic. Keep young bike riders in areas that are away from cars.

  • Exercise Safely In The Heat

    BE FIT

    Man sitting on bench beside his bike.

    Summer seems like an ideal time to exercise. After all, you don’t have to worry about slipping on ice or wearing extra layers to keep warm.

    But summer comes with its own set of safety issues. Heat illness can affect anyone, even people who are in great shape and healthy.

    What is heat illness?

    Heat illness happens when a person’s body gets too hot. This often happens when a person exercises in high temperatures.

    Heat illness can be mild to severe. Sometimes it’s just a sign that you need to cool off and get out of the sun. But other times, it can be dangerous or life-threatening.

    Time to chill out

    Signs of a mild heat illness include heat rash and heat cramps. A heat rash may be red and look like pimples. Heat cramps are muscle cramps or spasms.

    If you notice either of these signs when exercising, seek some shade and cool off. These are not usually serious conditions.

    People who have heart conditions or who follow a low-salt diet should talk to a doctor if they notice muscle cramps or spasms with exercise. If your heat rash doesn’t go away within a couple of days, see your doctor.

    When the heat is an emergency

    Heat exhaustion may cause:

    *  Heavy sweating

    *  Cold or clammy skin

    *  Feeling weak

    *  Weak but fast pulse

    *  Feeling sick

    *  Headache

    *  Fainting

    *  Dizziness

    If you notice these signs in yourself or another person, don’t wait. Seek shade or go indoors. Put cool, wet cloths on the body and head or take a cool bath. Get medical help if it doesn’t get better within an hour or if the person is throwing up.

    Heat stroke is the most severe kind of heat illness.

    It may cause:

    *  Temperature over 103ºF

    *  Skin that is clammy, hot or red, and even dry to the touch.

    *  Fast and strong pulse

    *  Headache or confusion

    *  Dizziness and/or fainting

    *  Feeling sick

    If you suspect heat stroke, get emergency medical care. Call 911 right away. Move the person to a cooler place. Apply cool cloths to their body. Do not give them anything to drink.

  • Exercise Safely In The Heat 2

    BE FIT

    In the summertime, it’s important to plan ahead. Be aware of the steps that will keep you safe when exercising in the heat.

    Choose your timing

    Exercising in the middle of the day exposes you to the worst of the heat and sun. This increases your risk of overheating. Early morning or evening are the best times to exercise in the heat.

    Dress for the weather

    Light colors and loose-fitting clothing allows your sweat to evaporate and releases heat from your body. A vented hat with a full, wide brim is also recommended.

    Hydrate well

    Make sure you are well hydrated in advance of exercising in the heat. While exercising, take frequent sips of water or a sports drink.  Once you finish, replenish with more water.

    Go slow

    If you are used to exercising indoors or new to exercise in general, go slow at first. Keep your exercise sessions short and low-intensity in the beginning. You may be able to build up gradually as your body adapts.

  • Exercising When The Days Are Short

    BE FIT

    December 21 marks the shortest day of the year. If you exercise outdoors, you may find yourself in the dark. Keep these things in mind if you go out at dawn or dusk:

    *  Wear reflective gear and bright colors. Also consider taking a head lamp or flashlight. You want to be as visible as possible and have your own light source to see.

    *  Don’t use headphones. You’ll want your hearing to be sharp when visibility is low.

    *  Go against the flow if you’re walking. Always walk against the flow of traffic. But, if you’re biking, go in the same direction of traffic.

    *  Take a friend if you can. They can keep you motivated and offer extra safety.

  • Get Moving To Boost Your Immunity

    BE FIT

    Exercise provides so many health benefits. Recent research now adds strengthening the immune system to the list. Here are three ways exercise can help fight infections and prevent you from getting sick.

    *  Regular bouts of moderate to high-intensity exercise reduce inflammation in the body. Lower levels of inflammation are linked to a decreased risk of chronic diseases such as heart disease, cancer, and diabetes.

    *  Exercise supports the healthy bacteria in the digestive tract. These bacteria, called the microbiome, make up about 70% of your immune system.

    *  Consistent physical activity may prevent the decline in immune function that is common as people age. Being active keeps the body’s defense system in peak condition.
