Exercise and sleep: Why getting fit requires getting your ZZZs.

If you are serious about exercise, you take steps to maximize your workouts in order to meet your fitness goals. Obviously, what you do for exercise matters. You probably also appreciate that nutrition is important, so you pay attention to what you eat. But there is another important step to achieving your fitness goals you may not be aware of—sleep. This is the topic of my Health & Fitness column in the Aiken Standard this week.

Why kids (and adults) should tri!

Triathlons are often regarded as the ultimate test of endurance. Combining swimming, cycling, and running, a triathlon requires a high level of fitness, endurance, and dedication. This is especially true for the Ironman triathlon, consisting of a 2.4 mile swim, 112 mile bike ride, and 26.2 mile run. The best athletes in the world take about eight hours to complete this event!

 

An Ironman is out of reach for most people, but almost everyone can benefit from training like a triathlete. Incorporating aquatic exercise, cycling, and running (or walking) in an exercise program leads to significant health and fitness benefits, the development and maintenance of important motor skills, and variety that can make exercise more enjoyable.

 

This is especially true for children. Participating in diverse activities is important for developing strength, endurance, balance, and coordination. Swimming, bicycling, and running are good ways to meet physical activity guidelines and develop a love for exercise. Children can benefit from the fitness and motor skills they develop from these activities when they play sports and adults can maintain fitness, prevent injury, and improve health and wellbeing.

The benefits of training like a triathlete for children and adults is the topic of my Health & Fitness column in the Aiken Standard this week.

Get out of debt—health debt—in 2019.

Getting out of debt is a worthwhile goal and a common New Year’s resolution. This almost always means financial debt, which is a burden for millions of Americans. Many individuals and families have gotten themselves into debt by spending too much and not saving enough. For most, this situation has been years in the making, has no simple solution, and will have an impact lasting years into the future. Reducing this debt is essential for achieving financial health.

This is not the only type of debt we face—many people are also in health debt. Poor eating habits and increasingly sedentary lifestyles have led to an obesity epidemic. The problem is widespread, since most Americans are overweight, fewer than half of US adults meet minimum recommendations for physical activity, and about one in six adults smoke. Alone and especially in combination, these poor health habits are the major causes of the most common, and preventable, diseases including diabetes, heart disease, and some cancers.

Even if we have not been diagnosed with diabetes or heart disease or other health problems, our lifestyle has put us on that path. Small changes in what we eat or how active we are have added up over the years to create a condition of poor health. And our overall health and potential complications get worse year after year, so the longer we are overweight and inactive, the worse our health is likely to be in the future. That is our health debt. This is the topic of my Health & Fitness column in the Aiken Standard this week.

Keeping up with fitness trends for 2019

There seems to always be something new in the fitness world. Whether it is a new piece of equipment in the gym, a new exercise class, or a new way to perform traditional exercises, the fitness industry is constantly evolving. Some of these become popular enough that they are considered “trends,” attracting attention from fitness experts and exercise novices alike.

Each year the American College of Sports Medicine (ACSM) surveys health and fitness professionals to identify exercise trends for the upcoming year. The 2019 report was published this month, so it is a good time to catch up on the leading fitness trends to look for in the upcoming year.

Happy Walktober! Celebrate by going for a walk outdoors.

 

Now that cooler fall weather is finally here (at least in our area), being active outdoors is more enjoyable. October is a great time to get outdoors and go for a walk! That is the spirit of Walktober, an initiative adopted by health organizations, companies, and communities around the globe.

Walking is a great way to be active to help you control your weight, increase your fitness, and improve your health. The most common form of exercise for most people is walking, and for good reason: walking doesn’t require any special equipment (beyond comfortable shoes) or skills, and you can do it almost anywhere.

You can meet basic physical activity recommendations by walking briskly for 30 minutes most days of the week. Even this amount of walking can lead to a lower risk of diabetes, heart disease, and some cancers as well as improved mental health, cognitive function, and greater feelings of wellbeing.

A health and fitness remodeling project

Losing weight are getting in better shape are common goals. Given that almost 40% of Americans are considered obese and less than 25% meet minimum exercise recommendations, there are many people who could benefit from changing their eating and activity habits.

Much of the time the focus is on losing lots of weight quickly. Many popular diet and exercise programs require making big changes to eating and exercise behaviors. These changes can promote rapid weight loss, but many can’t be maintained as lasting habits. But these changes do help a lot of people lose significant weight, at least for a while.

There are also many people who want to lose just a little weight, maybe 5–10 pounds, and get in better shape. This usually means building muscle and shedding fat, but not really losing much weight, a process that I call “remodeling”.

Exercise: The secret weapon for cancer prevention and treatment.

Exercise has broad and significant health benefits, making it among the most important healthy behaviors you can adopt. These benefits include improved muscular strength and endurance, stronger bones, and better cardiovascular system function. Exercise is also essential for maintaining a healthier body weight and body composition and improving metabolic health through blood glucose and lipid regulation.

But exercise causes changes at the cellular and hormonal levels that have even broader effects. Among these is a reduction in inflammation, which has long been linked to a lower risk of heart attack. Accumulating research suggests that reduced inflammation and improved immune system function may be an important way in which exercise reduces the risk of cancer. The role of exercise in cancer prevention and treatment is the topic of my Health & Fitness column in the Aiken Standard this week.

While we typically associate the immune system with communicable diseases like cold or flu, our immune system plays an important role in the body’s defense against cancer. Conditions like obesity, poor nutrition, and a sedentary lifestyle can promote chronic inflammation. Among other negative effects, inflammation can interfere with the normal functioning of the immune system. This impairs your cells’ natural cancer-fighting capacity, making it more likely that cancer will develop and spread. Exercise can reverse the immune system damage caused by chronic inflammation, reducing the risk of cancer development and progression as well as making it less likely you will become sick from a cold or flu.

The idea that exercise can reduce the risk of cancer isn’t new. I have written previously about the fact that regular physical activity can lower breast cancer risk by as much as 30%, improve survival, and reduce the risk of recurrence. A recent study confirms that high levels of physical activity can significantly lower the risk of breast cancer along with many other common types including colon, bladder, lung, kidney, and endometrial cancers.

In addition to helping reduce the risk of cancer development and recurrence, regular exercise can help you handle cancer treatment better. To be sure, cancer treatment can lead to extreme physical consequences including losses in weight, muscle mass, strength, and endurance. At least some of this is due to more time resting and less time being active, the effects of which occur within days and get worse over time.

You may have noticed this as weakness and fatigue after spending a few days in bed with the flu. Muscle strength declines at a rate of over 1% per day of bed rest, and can be 50% lower following as little as three weeks. That reduction in strength could limit a person who was already deconditioned to a point where he or she would have difficulty completing the most basic activities of daily living. Bed rest can also reduce bone density, exposing patients to a greater risk of fracture.

The fitter you are when you begin treatment, the fitter you will be at the end because you have “saved” more strength and endurance in your fitness bank. You simply have more you can lose before you get to a point at which you can’t complete your normal activities. In fact, maintaining physical activity is a key component of cancer treatment. And post-cancer exercise programs are becoming more common as a way to help women recover from cancer treatment and rebuild strength, endurance, and feelings of wellbeing.

The best approach is to be active now to reduce your risk of cancer (and many other chronic diseases) and build strong muscles and bones to help you successfully handle any cancer treatment or periods of other illness you may encounter later.
