Effects of a regular walking exercise program on behavioral and biochemical aspects in elderly people with type II diabetes.
ABSTRACT The present study examined the effects of a regular walking exercise program on behavioral (daily physical activity, physical strength, energy consumption) and biochemical (fasting blood glucose [FBG], glycated hemoglobin [HbA1c], total cholesterol, triglycerides [TG], low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol) aspects of elderly people with type II diabetes. A randomized and stratified experimental design was used with experimental and control groups. The experimental group was subjected to a 6 month walking exercise program, involving walking exercise three times per week for 50 min, and a 4 week education program on diet control and the prevention of complications, once per week for 20 min. Post-test was conducted after 3 and 6 months to examine short- and long-term behavioral and biochemical effects. The regular walking exercise program effectively increased daily physical activity, physical strength, and energy consumption (behavioral aspects), and decreased FBG, HbA1c, and TG levels (biochemical aspects) in elderly people with type II diabetes. The incidence of type II diabetes complications might be reduced by implementing a regular walking exercise program.

ABSTRACT: Comparisons of physical activity measured by accelerometers in overweight/obese adults and their normal-weight counterparts are limited. Compliance with the 2002 Institute of Medicine (IOM) exercise recommendations for 60 minutes of moderate-intensity exercise daily has not been reported. The purpose of this study was to compare physical activity, as measured by accelerometers, in overweight/obese adults vs. normal-weight controls and to assess compliance with recommendations for physical activity by the IOM in 2002 and by the Centers for Disease Control and Prevention and American College of Sports Medicine in 1995 for 30 minutes of moderate-intensity activity, preferably all days of the week. Sixty-two overweight/obese subjects, BMI > or = 25, included 31 adults, 12 men and 19 women, 25 to 69 years old, and their normal-weight controls, BMI 18.5 to 24.9, matched for gender, age, and height. Body composition was assessed using DXA. Physical activity was measured with Actigraph accelerometers (MTI, Fort Walton Beach, FL) worn by each participant for 7 consecutive days. Accelerometry data indicated that overweight/obese adults recorded approximately 60 counts per minute less per day and spent 21 minutes less engaged in moderate or greater intensity activity than their normal-weight counterparts. Although 71% to 94% of those studied met 1995 recommendations, only 13% of overweight/obese subjects and 26% of normal-weight participants met 2002 exercise recommendations. These results suggest that daily minutes spent in moderate-intensity activity or greater are associated with weight status and that the 2002 IOM recommendations may be difficult to meet even for normal-weight individuals.Obesity 12/2006; 14(12):2259-65. · 3.92 Impact Factor

ABSTRACT: This paper, which has been reviewed and approved by the Board of Directors of the American Sleep Disorders Association, provides the background for the Standards of Practice Committee's parameters for the practice of sleep medicine in North America. The growing use of activity-based monitoring (actigraphy) in sleep medicine and sleep research has enriched and challenged traditional sleep-monitoring techniques. This review summarizes the empirical data on the validity of actigraphy in assessing sleep-wake patterns and assessing clinical and control groups ranging in age from infancy to elderly. An overview of sleep-related actigraphic studies is also included. Actigraphy provides useful measures of sleep-wake schedule and sleep quality. The data also suggest that actigraphy, despite its limitations, may be a useful, cost-effective method for assessing specific sleep disorders, such as insomnia and schedule disorders, and for monitoring their treatment process. Methodological issues such as the proper use of actigraphy and possible artifacts have not been systematically addressed in clinical research and practice.Sleep 06/1995; 18(4):288-302. · 5.10 Impact Factor

ABSTRACT: This analysis describes physical activity levels and factors associated with physical activity in an ethnically diverse (African American, Native American, white) sample of rural older adults with diabetes. Data were collected using a population-based, cross-sectional stratified random sample survey of 701 community-dwelling elders with diabetes completed in 2 rural North Carolina counties. Outcome measures were as follows: first, physical activity in the past year, and second, days physically active in the prior week (0-7). Potential correlates included personal and health characteristics and were evaluated for statistical significance using logistic regression models. About half (52.5%) of the participants stated that they had engaged in physical activity in the past year. Among those, 42.5% stated that they had no days with at least 30 minutes of continuous physical activity in the prior week, while 21.5% reported daily physical activity. Common activities were walking and housework. Correlates of physical activity in the past year and days active in the prior week included measures of physical health and mobility. Physical activity in this ethnically diverse sample of rural elders with diabetes is limited. Effort must be invested to increase physical activity in these groups.The Journal of Rural Health 02/2006; 22(2):164-8. · 1.44 Impact Factor
