  1. Self-regulatory strength depletion and muscle-endurance performance: a test of the limited-strength model in older adults.

    Journal of Aging and Physical Activity 19(3):177 (2011) PMID 21727299

    Self-regulation consumes a form of strength or energy. The authors investigated aftereffects of self-regulation depletion on muscle-endurance performance in older adults. Participants (N = 61, mean age = 71) were randomized to a self-regulation-depletion or control group and completed 2 muscle-e...
  2. Item-response-theory analysis of two scales for self-efficacy for exercise behavior in people with arthritis.

    Journal of Aging and Physical Activity 19(3):239 (2011) PMID 21727304

    Benefits of physical activity for those with arthritis are clear, yet physical activity is difficult to initiate and maintain. Self-efficacy is a key modifiable psychosocial determinant of physical activity. This study examined two scales for self-efficacy for exercise behavior (SEEB) to identif...

  6. Predicting habitual physical activity using coping strategies in older fallers engaged in falls-prevention exercise.

    Journal of Aging and Physical Activity 19(3):189 (2011) PMID 21727300

    One third of adults over 65 yr old fall each year. Wide-ranging consequences include fracture, reduced activity, and death. Research synthesis suggests that falls-prevention programs can be effective in reducing falls by about 20%. Strength and balance training is the most efficacious component,...
  7. Enhancing strength and postocclusive calf blood flow in older people with training with blood-flow restriction.

    The response of calf-muscle strength, resting blood flow, and postocclusive blood flow (PObf) were investigated after 4 wk of low-load resistance training (LLRT) with and without blood-flow restriction in a matched-leg design. Ten untrained older individuals age 62-73 yr performed unilateral pla...
  8. Synergistic effect of social support and self-efficacy on physical exercise in older adults.

    Journal of Aging and Physical Activity 19(3):249 (2011) PMID 21727305

    The purpose of the current study was to examine whether the effects of social support on physical exercise in older adults depend on individual perceptions of self-efficacy. Three hundred nine older German adults (age 65-85) were assessed at 3 points in time (3 months apart). In hierarchical-reg...
  9. The impact of high-calorie-expenditure exercise on quality of life in older adults with coronary heart disease.

    Journal of Aging and Physical Activity 19(2):99 (2011) PMID 21558566

    The acceptability of a high-calorie-expenditure (HCE) exercise program in older coronary heart disease patients participating in a behavioral weight-control program was evaluated. Seventy-four overweight patients (median age 63 yr) were randomly assigned to a 5-mo intervention of HCE exercise (3...
  10. Physical activity and cognitive-health content in top-circulating magazines, 2006-2008.

    Journal of Aging and Physical Activity 19(2):147 (2011) PMID 21558569

    Physical activity may promote cognitive health in older adults. Popular media play an important role in preventive health communication. This study examined articles discussing associations between physical activity and cognitive health in top-circulating magazines targeting older adults. 42,753...
  11. Changes in executive function after acute bouts of passive cycling in Parkinson's disease.

    Journal of Aging and Physical Activity 19(2):87 (2011) PMID 21558565

    Individuals with Parkinson's disease (PD) often experience cognitive declines. Although pharmacologic therapies are helpful in treating motor deficits in PD, they do not appear to be effective for cognitive complications. Acute bouts of moderate aerobic exercise have been shown to improve cognit...
  12. The effect of guided relaxation and exercise imagery on self-reported leisure-time exercise behaviors in older adults.

    Journal of Aging and Physical Activity 19(2):137 (2011) PMID 21558568

    The purpose of this study was to examine the effects of a 6-wk intervention that used guided relaxation and exercise imagery (GREI) to increase self-reported leisure-time exercise behavior among older adults. A total of 93 community-dwelling healthy older adults (age 70.38 ± 8.15 yr, 66 female) ...
  13. Stair-ascent performance in elderly women: effect of explosive strength training.

    Journal of Aging and Physical Activity 19(2):117 (2011) PMID 21558567

    Explosive-type strength training may alter kinetics and neuromuscular activity during stair ascent in elderly women. This may improve functional ability. Nineteen women (69.7 ± 3.4 yr) were randomly allocated to strength training (TG; twice per wk, 12 wk) or a control group (CG). Stair ascent wa...
