Physical activity helps older adults maintain their health

By Linda Cronk, Michigan State University Extension 

 

Regular exercise and physical activity are vital at any age, including for older adults. The National Institute on Aging says that being active helps older adults:

  • Keep and improve strength to stay independent
  • Have more energy to do things
  • Improve balance
  • Prevent or delay some diseases like heart disease, diabetes, and osteoporosis
  • Perk up mood and reduce depression

According to Living a Healthy Life with Chronic Conditions, by Dr. Kate Lorig, to get the greatest benefit from physical activity, older adults need to try four types of exercise: endurance, strength, balance and flexibility exercise.

Endurance activity

Many older adults avoid endurance activity, also called aerobic exercise, because they are unsure about how much is safe for older adults. “The most important thing is that some activity is better than none,” Dr. Lorig said. “If you start off doing what is comfortable and increase your efforts gradually, it is likely that you will build a healthy, lifelong habit.” There are three building blocks for a safe, moderate-intensity goal for endurance activity:

  • Frequency means how often you exercise. The Center for Disease Control recommends aerobic physical activity in episode of at least 10 minutes and, if possible, spread it out through the week.
  • Intensity is how much effort you use or how hard you work. Endurance or aerobic exercise is safe at a moderate intensity. You will feel warmer, you breathe deeper and faster, your heart rate will rise moderately and you will still feel like you can continue a while longer.
  • Time is how long you exercise each time you are active. At least 10 minutes is a good starting place. If that is too challenging, start with a smaller amount of time. You can work up from there, with a moderate intensity goal of 150 minutes per week. You can try to attain your 150 minute goal by exercising 30 minutes five days per week.
Strength training

We need to exercise our muscles in order to maintain our physical strength as we get older. Otherwise, our muscles shrink from lack of use. According to the book Living a Healthy Life With Chronic Conditions, moderate-intensity muscle-strengthening exercise of all major muscle groups should be done at least two days per week.

Flexibility exercises

Being flexible means you can move comfortably in your daily life with a minimum of pain and stiffness. A series of gentle stretching exercises done at least three to four days per week can help you improve and maintain flexibility as you get older.

Balance exercises

Falling is one of the most challenging events for older adults. Injury from falls, such as broken bones, is a common experience for those with balance issues. Strong and coordinated muscles in your core and legs are key for good balance. Certain exercises, including qi gong, tai chi, yoga and others are good for improving and maintaining balance.

 

You can find a free user-friendly exercise book and DVD through the National Institute on Aging website called Go4Life.

 

According to Michigan State University Extension, once you start exercising and become more physically active, you will begin to see results quickly. In a few short weeks, you will feel stronger and more energetic, and you will be able to do things easier, faster or longer than before. Your body will get used to a higher level of activity and you can continue to build on those benefits by doing more. Be sure to check with your doctor before you begin an exercise program.

 

Spice up spring salads with Michigan-grown greens

Adding seasonal greens, especially dark leafy varieties, to your salads provides an abundance of nutrients and flavor (see chart for flavor characteristics). Salad greens are vegetables harvested for their leaf and petiole, the stem portion of the leaf. The greens may be harvested at different stages of development:

    • Microgreens: Seeds are planted at high density and microgreens are harvested once the cotyledons, the first leaves to emerge when a plant germinates, have fully developed or when the first true leaves have emerged, usually when the plant is half to two inches in height.
      • Baby leaf: Seeds are planted at high density, and leaves are harvested when the plants have four true leaves and are two to five inches tall, still young and tender. Mixtures of various baby leaf salad greens are often marketed as mesclun, spring mix or field greens.
  • Leaf: Harvesting leaves beyond the baby leaf stage requires the greens to be cut into smaller pieces for use in salads. Many greens become less tender after the baby leaf stage, but lettuce and fresh herbs work well for salads in leaf form. Leaf-stage kale and Swiss chard can be chopped into bite-sized pieces for salad. Often leaves, such as mustard greens and collard greens, are cooked once they reach this stage.

  • Head: This growing pattern is found in lettuce and some Asian greens such as pac choi. Typically, only lettuce heads are used as salad greens, as mature Asian greens are less tender and better suited for cooking.

Popular salad greens available in the springtime in Michigan include lettuces, mesclun mix, spinach, kale, arugula and chard. Asian leafy vegetables such as pac choi and tatsoi are also gaining popularity in the United States as salad greens in their baby leaf and microgreen forms. To reduce the risk of pathogen growth, store leafy greens in the refrigerator at 41 degrees Fahrenheit or lower and wash salad greens under cool running water prior to use. It does not hurt to give them a quick rinse, even if they are labeled pre-washed.
