Healthy people exercising

A recent review about the relationship between exercise and mental health in the elderly discussed the results of clinical research and biological explanations for the effects of exercise on mental health. Exercise is studied in the elderly in depression, Alzheimer’s disease and Parkinson’s disease.

Dr. Shock has discussed the topic of exercise and depression before on his blog. The conclusion was that exercise is more effective than no treatment and that for mild to moderate depression it is efficacious and for severe depression it should be added to other treatments in the treatment program. In this more recent review on exercise and mental health the focus is on the elderly. Data on elderly patients are scarcer. Nevertheless investigations have shown that aerobic exercise at an intensity consistent with public health recommendations can be regarded as an effective treatment of mild and moderate depression. There is some evidence for a possible dose-response effect of exercise on depression. Treatment not prevention? Indeed, this topic has not yet been extensively studied in the elderly yet.

What does that mean: aerobic exercise at an intensity consistent with public health recommendations?

Basic recommendations from the The American College of Sports Medicine (ACSM) and the American Heart Association (AHA).

  • Do moderately intense aerobic exercise 30 minutes a day, five days a week
  • Or Do vigorously intense aerobic exercise 20 minutes a day, 3 days a week
  • And Do eight to 10 strength-training exercises, 10-15 repetitions of each exercise twice to three times per week
  • And If you are at risk of falling, perform balance exercises
  • And Have a physical activity plan.

What is a physical activity plan?
In short consult your GP before starting to exercise.

Older adults or adults with chronic conditions should develop an activity plan with a health professional to manage risks and take therapeutic needs into account. This will maximize the benefits of physical activity and ensure your safety.

Physical Exercise and Alzheimer’s Disease

  • Epidemiological studies have associated exercise with reduced risk of Alzheimer’s disease
  • Exercise as treatment for dementia showed efficacy for mood status, psychosocial functioning, physical health and caregiver distress
  • Daily 30 minutes of exercise diminishes the number of hospitalization needed, decreased depressive symptoms, increased quality of life in patients with Alzheimer’s disease
  • In comparison with a sedentary group, the group with a year of exercise intervention improved in quality of life

Physical Exercise and Parkinson’s Disease
Also in Parkinson’s Disease epidemiological studies have shown that exercise can protect against the disease. The disease is associated with tremor, rigidity, and hypokinesia which can result in falls and tiredness.The main advantage of exercise in PD is improvement of functional capabilities due to strength and balance training. This improves motor skills, improves their quality of life and reduces the number of falls.

Although somewhat limited, evidence suggests that exercise training is beneficial to patients with PD, especially in functional capacity and ADLs improvement

The protective effect of exercise can be explained by effects on the brain as can be read in the Neuroscience of Exercise on Dr. Shock’s blog.

By now, most of us have heard about the new recommended guidelines for adults under 65 to get at least 30 minutes a day of moderately intense cardio, five days a week. The American College of Sports Medicine (ACSM) and the American Heart Association (AHA) Guidelines here

However, many people have a hard time finding time to exercise after work with long commutes, family obligations and just maintaining the household. At work, people face deadlines, scores of emails, phone calls and piles of paperwork to address. One way for employers and employees to help keep health care costs down, reduce risks of illness, and help improve overall health and well being is to encourage employees to step up their steps!

According to Health Enhancement Systems’ report, Walking: The Health and Economic Impact, there’s no wellness investment that pays a higher dividend than a robust walking program. Here are just a few of the health-related findings specifically associated with walking:

• Protects against heart attack and stroke.
• Helps prevent weight gain.
• Reduces risk of diabetes.
• Lowers overall mortality.
• Decreases heart disease risk.
• Maintains a healthy BMI.
• Enhances fitness with little time or effort.

According to a Loughbrough University study, women who took three 10-minute brisk walks, 5 days a week, had nearly the same increases in fitness levels as women who walked continuously for 30 minutes. In fact, those who walked in briefer sessions lost more weight and inches around the waist than the 30-minute walkers! More here from Health Enhancement Systems

Why Walk?
• Walking is the only exercise where participation rates don’t decrease as
individuals reach middle age and older. One national survey found that
compared with any other group, men 65 and older had the highest percent
of regular walkers — 39.4%.14
• It’s the most popular physical activity in America. More than 56 million people
walk for fitness at least 100 days a year.15
• Walking is inexpensive and easy. All a person needs is a pair of comfortable,
supportive shoes.16
• It comes naturally and can be done in connection with other daily activities —
for example: walking to work, circling the mall or grocery aisles, walking
the dog, or pacing while on the phone.
• Walking is a low impact, safe form of exercise — even for those who are
obese or have arthritis.

How to Find Time to Walk at Work
Employers cannot mandate that employees walk at work. And we don’t encourage employees to shirk their work responsibilities to complete their walking goals. But many smokers take “smoke breaks” at work, leaving the office for 10-15 minutes to smoke a cigarette outdoors. Why shouldn’t the nonsmokers take advantage of a similar break in the work flow for a far healthier result!

And the lunch “hour” is also a great time to get coworkers together and take a brisk walk outside the office or at a nearby mall. Although some do not take a full hour for lunch, and others may want to split the lunch break up into 30 minutes of walking and then time to eat lunch, there are many ways you can fit in a walk a few times during the workweek lunch time.

• A simple plan would be to set up 3 ten-minute walk breaks inside the office building if there is enough space, or weather permitting outside the office.

• Alternatively, staff can set up 20-30 minute walk breaks at lunch time.

• And for those lucky few that take a train or bus or subway to work, try getting off a few blocks or even a half mile earlier than normal and then walk to your destination from there. it’s an easy way to add a few steps to your day and explore your own neighborhood.

Benefits of Walking at Work
Employers have found that allowing employees to take minibreaks leads to increased productivity and job satisfaction. According to Health Enhancement Solutions, walking, like other physical activity, employee productivity increases with physical activity. Findings include:
• Better concentration 1
• Enhanced memory and learning 2
• Improved ability to make complex decisions 1
• Increased physical stamina. 3, 4

Walking promotes an overall sense of wellness by helping people to:
• Control appetite and increase the body’s metabolism 5
• Improve mood and well-being 2, 4
• Reduce symptoms of depression and anxiety 2
• Relax, feel more energetic, and control stress 4, 6
• Sleep better. 7, 8

Programs to Encourage People to Walk at Work
• Employers can encourage or even provide low cost pedometers to help staff monitor the steps they take every day. Recomended Top Ten Pedometers. The Sportline 360 Fitness Pedometer is $22 pedometer that’s easier to use, lightweight and clips on a belt or waistline of trowsers Order here
• Employers or Employees can start a Walking Club at work.

Walking Club Tips
• Spread the word – use email, voicemail and posters to get people interested
• Make it fun and make it friendly. Start slowly so that none of your co-workers are too intimidated to continue.
• Set a Walking club schedule so that it become part of your regular daily routine. Even if some people cannot commit to every day, make sure at least 2 of you keep up the schedule to maintain momentum.
• Encourage your colleagues to take walking breaks instead of coffee breaks in order to get some fresh air– and avoid problems sleeping alter at night due to too much caffeine.
• Promote a noon-hour walking group.
• Create an indoor walking route in case of poor weather – go to a local mall if your workspace is not conducive to walking. Walk the stairwells if your office is a high rise or building with access to stairs.
• Track your walking groups progress on a graph or poster in a main foyer to inspire others to join.
• Hold a contest or challenge between departments.
• Host a heart healthy nutritious potluck before or after your walking groups noon-hour walk.
• Ask your colleagues when they would prefer to walk. Some people need a “pick me up” in the morning while others require one in the later afternoon.
