Physical activity - Fact vs. Fiction

There is one thing the majority of people in the U.S. have in common – most of us are not as physically active as we should be.  On top of that, there are many fallacies people erroneously have about physical activity or exercise and nutrition that need to be cleared up.

Here are some common misconceptions on physical activity needing clarification:

·         The only reason for physical activity is to improve heart health

Not true.  A moderately active lifestyle incorporating brisk walking, bicycling, swimming, or jogging is certainly good for the heart and cardiovascular system.  However, physical activity is also linked with decreased risk for certain cancers, diabetes, high blood pressure, osteoporosis, depression, enhancing immunity and improving self-esteem.  To be able to move with ease and be active is a gift and why not take advantage of it.

·         You’re busy and on your feet all day at work – of course, you’re active!

When we say we’re “busy” throughout the day, it isn’t necessarily the same as being physically active.  You may be on your feet a lot during the day but there will be times you are standing without little movement.  Exercise means planned, repetitive movement that keeps your heartrate above normal for a certain length of time.  An active lifestyle means at least 30 minutes of physical activity on most – if not all – days of the week.  Physical activity can come from sports or recreational activities or the everyday “active” tasks of living, including walking up steps and many household chores such as mopping the floor or raking leaves.

·         Being physically active takes a lot of time and work

There are many ways to weave physical activity in throughout the day.  It does not necessarily have to be an intense workout or target a specific heart rate for health benefits.  What really counts is consistent, regular and moderate exercise to get yourself in better shape.

·         No pain, no gain

Achieving a gain from exercise can at times be unpleasant but pain is not a natural consequence of exercise or physical activity.  Pain is usually a signal of something needing to be addressed and evaluated before it gets worse.  However it’s not unusual to have some soreness after lifting weights or intense interval training or a long distance workout.  Usually this pain is from the buildup of lactic acid that accompanies the anaerobic effort of lifting or doing intense workouts leading to muscle fatigue.  There can be discomfort but it should only be temporary and not long lasting. 

·         “I haven’t exercised in years.  At my age I don’t need to be concerned with it”

It’s really never too late to get in extra movement throughout the day.  Regular physical activity has been shown to improve the functional status and quality of life of older adults.  In fact, it’s recommended that adults ages 65 and older do at least 150 minutes of moderate-intensity aerobic physical activity throughout the week.  Older adults can benefit not just physically from exercise but also mentally – it reduces depression, anxiety, and can lead to better sleep.  Being active and regular movement can also help relieve the disability and pain associated with conditions such as arthritis – staying physically active can be enjoyed even if it starts late in life.
