Physical Activity and Older Adults

Regular physical activity has been shown to improve the functional status and quality of life of older adults. It is recommended that, if appropriate, older adults should engage in at least 30 minutes of moderate-intensity physical activity 5 days per week.

BENEFITS OF PHYSICAL ACTIVITY FOR OLDER ADULT:

Many non-communicable diseases (NCDs) prevalent in older adults can benefit from participation in regular physical activity:

• Cardiovascular disease (coronary heart disease, stroke);
• Osteoarthritis (a disease that causes joint swelling and pain and limits movement);
• Osteoporosis (a disease in which bones become fragile and more likely to break);
• Hypertension (elevated blood pressure and is also a risk factor for several other NCDs).

While being active from an early age can help prevent many diseases, regular movement and activity can also help relieve the disability and pain associated with these conditions. Importantly, the benefits of physical activity can be enjoyed even if regular practice starts late in life. It has been suggested that older adults engaged in regular physical activity demonstrate improved:

• Balance
• Strength
• Coordination and motor control
• Flexibility
• Endurance.

Consequently, physical activity can reduce the risk of falls-a major cause of disability among older people. Physical activity has also been shown to improve mental health and cognitive function in older adults and has been found to contribute to the management of disorders such as depression and anxiety. Active lifestyles often provide older persons with regular occasions to make new friendships, maintain social networks, and interact with other people of all ages.

Despite this, a global trend of declining physical activity participation that is associated with increasing age has been observed.

 

RECOMMENDATIONS FOR OLDER ADULTS:

Physical activity for older adults can take many forms (e.g. walking, swimming, stretching, dancing, gardening, hiking, cycling or organised exercise sessions). However, there are several important considerations specific to the older adult population with regard to physical activity recommendations:

• Recommended intensity of aerobic activity should take into account the older adult's aerobic fitness.
• Activities that maintain or increase flexibility are recommended.
• Balance exercises are recommended for older adults at risk of falls.
• Older adults that have medical conditions or disabilities that may affect their capacity to be physically active should seek advice from a doctor.

IMPLICATIONS OF PHYSICAL ACTIVITY IN OLDER ADULTS:

The number of people over 60 years old is projected to double in the next 20 years. Most of these older persons will be living in developing countries. Reducing and postponing age-related disability is an essential public health measure and physical activity can play an important role in creating and sustaining well-being at all ages.

Walking faster key to survival among elderly

Washington, Jan 5 (IANS) A higher walking speed could be the key to older adults surviving for longer, a study suggests. Stephanie Studenski of the University of Pittsburgh in the US and her colleagues conducted a study to co-relate gait speed with survival in older adults.

The study analyzed nine studies between 1986 and 2000 using individual data from 34,485 community-dwelling adults aged 65 years or above, reports the Journal of the American Medical Association.

Participants had an average age of 73.5 years, while 59.6 percent were women and 79.8 percent were white, according to a Pittsburgh statement.

Walking speed was calculated for each participant using distance in meters and time in seconds.

Researchers said slower walking speed indicated weak organ systems and higher energy cost of walking, thus indicating poor survival rate.

During the course of the study, there were 17,528 deaths. The overall five-year survival rate was 84.8 percent while the 10-year survival rate was 59.7 percent.

The researchers found that walking speed was associated with differences in the probability of survival at all ages in both sexes, but was especially notable after 75 years of age.
