The benefits of exercise in geriatric women

The impact of Tai Chi exercise on coronary heart disease: a systematic review

PURPOSE

(a) To explore current studies on Tai Chi and its impact on coronary heart disease (CHD), (b) provide critique of existing studies, and (c) provide recommendations for clinical practice and future research.

DATA SOURCES

Comprehensive review of literature.

CONCLUSIONS

Tai Chi is a safe alternative exercise for patients who are at risk of CHD or with existing CHD. Implementing Tai Chi exercise may improve serum lipids, blood pressure, and heart rate.

IMPLICATIONS FOR PRACTICE

Nurse practitioners (NPs) are in an ideal position to facilitate health promotion and disease prevention. NPs may prescribe Tai Chi as an alternative exercise therapy for their patients who are at risk for developing CHD and even for those with existing CHD. Tai Chi exercise may help prevent and even reverse the progression of cardiac disease.

Leisure-Time Physical Activity and Health-Care Utilization in Older Adults

This study examined whether leisure-time physical activity (LTPA) was associated with health-care utilization in a racially diverse sample of rural and urban older adults. Community-dwelling adults (N= 1,000, 75.32 ± 6.72 years old) self-reported participating in LTPA and their use of the health-care system (physician visits, number and length of hospitalizations, and emergency-room visits). After controlling for variables associated with health and health-care utilization, older adults who reported lower levels of LTPA also reported a greater number of nights in the hospital in the preceding year. There was no support, however, for a relationship between LTPA and the other indicators of health-care utilization. Our findings suggest that being physically active might translate to a quicker recovery for older adults who are hospitalized. Being physically active might not only have health benefits for older persons but also lead to lower health-care costs.

Effects of Tai Chi and resistance training on cardiovascular risk factors in elderly Chinese subjects: a 12-month longitudinal, randomized, controlled intervention study

BACKGROUND

Tai Chi is rapidly gaining in popularity, worldwide. This study was performed to assess its impact on cardiovascular risk factors in comparison with resistance training exercises in elderly Chinese subjects.

METHODS

A total of 207 healthy elderly participants (65-74 years, 113/207 (55%) men) were randomly assigned to one of three intervention groups: (1) Tai Chi, three times/week for 1 h/session (n = 64); (2) resistance training exercise, three times/week for 1 h/session (n = 65); (3) usual level of physical activity control group (n = 78). Anthropometric measures, dual X-ray densitometry body composition, blood pressure, lipids, glycaemic and insulin sensitivity indices were measured at baseline and 12 months. Repeated-measures analysis of variance (anova) was used to assess the between-group changes using a last-observation-carried-forward intention-to-treat approach.

RESULTS

A total of 180 (87.0%) subjects completed the study. No significant changes were identified in the Tai Chi group compared to the resistance training or control group. Of the primary outcomes, only the improvement in the insulin sensitivity index differed, being significantly greater in the resistance training than in the control group [mean difference 0.018 (95% confidence interval ( CI) 0.000-0.037) mmol glucose/min, P = 0.02), and tending to be greater than in the Tai Chi group (mean difference 0.019 (95% CI 0.000-0.038) mmol glucose/min, P < 0.06).

CONCLUSION

Tai Chi had no significant effect on any measure compared to the controls, whereas resistance training improved the insulin sensitivity index in this 12-month study.

Non-Equipment Exercise-Related Injuries Among U.S. Women 65 and Older: Emergency Department Visits from 1994–2001

The objective of this study was to estimate the relative frequency, types of injury, types of exercise, and mechanism of non-equipment exercise-related injury among women 65 and older. Methods included a descriptive analysis of emergency department (ED) visits to hospitals participating in the National Electronic Injury Surveillance System (NEISS). Researchers identified 851 exercise-related injuries to women 65 and older. Estimates are that 37729 older women were treated in emergency departments for injuries related to non-equipment type exercise activity from 1994-2001. Although there are many benefits to exercise, injuries due to overuse and existing physical conditions such as osteoporosis are a concern for active older women. Promotion of safe exercise activities and programs for older women are recommended.

The Impact of Exercise on Age-Related Physiological Changes and Pathological Manifestations

The most inactive Americans are over the age of 65. Age-related physiological changes affect the ability to perform certain types of exercise. The cardiovascular and musculoskeletal systems are directly affected by these age-related changes, resulting in the modification of an exercise regimen. Individualized exercise programs depend on comorbidities, which limit the risks and maximize the benefits of exercise. Evidence supports the benefits of wellness exercise programs. The type of exercise beneficial for an individual is dependent on his or her overall health, disease state, and medications. Age-related physiological changes lead to the development of a wide range of chronic disorders that are often mistakenly assumed to be part of the normal aging process. The purpose of this article is to review the age-related physiological changes associated with exercise, the benefits and risks of exercise, and the wellness guidelines for initiating exercise in an individual over 65 years old. Included in this article is a discussion of the specific exercise guidelines for osteoarthritis, osteoporosis, obesity, psychological health, and diabetes mellitus.
