Validity Of Boston Marathon Qualifying Times, Paul M. Vanderburgh Mar 2015

Validity Of Boston Marathon Qualifying Times, Paul M. Vanderburgh

Paul M. Vanderburgh

Purpose: To assess the validity of Boston Marathon qualifying (BMQ) standards for men and women. Methods: Percent differences between BMQ and current world records (WR) by sex and age group were computed. WR was chosen as the criterion comparison because it is not confounded by intensity, body composition, lifestyle, or environmental factors. A consistent difference across age groups would indicate an appropriate slope of the age-vs-BMQ curve. Inconsistent differences were corrected by adjusting BMQ standards to achieve a uniform percentage difference from WR. Results: BMQ standards for men were consistently ~50% slower than WR (mean 51.5% ± 1.4%, range 49.6–54.4%), …


Political Drive To Screen For Pre-Dementia: Not Evidence Based And Ignores The Harms Of Diagnosis, David Le Couteur, Jenny A. Doust, Helen Creasey, Carol Brayne Feb 2015

Political Drive To Screen For Pre-Dementia: Not Evidence Based And Ignores The Harms Of Diagnosis, David Le Couteur, Jenny A. Doust, Helen Creasey, Carol Brayne

Jenny Doust

Current policy in many countries is aimed at increasing the rates of diagnosis of dementia and cognitive impairment.1 2 3 This policy drive has been accompanied by research into early detection of dementia, including preclinical identification of underlying neurobiology that might later be associated with dementia.4 Although the clinical features of people with established dementia are unmistakable,5 6 the ability of these preclinical features to predict future disease is less clear. Nevertheless, the belief that there is value in screening for “pre-dementia” or mild cognitive impairment is creeping into clinical practice, with the resulting overdiagnosis having potential adverse consequences for …


Impaired Skeletal Muscle Blood Flow Control With Advancing Age In Humans: Attenuated Atp Release And Local Vasodilation During Erythrocyte Deoxygenation, Brett S. Kirby, Anne R. Crecelius, Wyatt F. Voyles, Frank A. Dinenno Jan 2015

Impaired Skeletal Muscle Blood Flow Control With Advancing Age In Humans: Attenuated Atp Release And Local Vasodilation During Erythrocyte Deoxygenation, Brett S. Kirby, Anne R. Crecelius, Wyatt F. Voyles, Frank A. Dinenno

Anne R. Crecelius

Rationale: Skeletal muscle blood flow is coupled with the oxygenation state of hemoglobin in young adults, whereby the erythrocyte functions as an oxygen sensor and releases ATP during deoxygenation to evoke vasodilation. Whether this function is impaired in humans of advanced age is unknown. Objective: To test the hypothesis that older adults demonstrate impaired muscle blood flow and lower intravascular ATP during conditions of erythrocyte deoxygenation. Methods and Results: We showed impaired forearm blood flow responses during 2 conditions of erythrocyte deoxygenation (systemic hypoxia and graded handgrip exercise) with age, which was caused by reduced local vasodilation. In young adults, …


Technology And Aging: An Emerging Research And Development Sector In Maine, Carol H. Kim, David Neivandt, Lenard W. Kaye, Jennifer A. Crittenden Jan 2015

Technology And Aging: An Emerging Research And Development Sector In Maine, Carol H. Kim, David Neivandt, Lenard W. Kaye, Jennifer A. Crittenden

Maine Policy Review

The authors discuss the importance of research for developing products and services that cater to the needs of a rapidly growing aging population and provide examples of projects underway at the University of Maine. Products designed to improve and protect older adult health and well-being represent a significant opportunity for economic growth in Maine.


Effect Of Tai Chi Exercise Combined With Mental Imagery Theory In Improving Balance In A Diabetic And Elderly Population, Abdulrahman Alsubiheen, Jerrold S. Petrofsky, Noha S. Daher, Everett Lohman, Edward Balbas Jan 2015

Effect Of Tai Chi Exercise Combined With Mental Imagery Theory In Improving Balance In A Diabetic And Elderly Population, Abdulrahman Alsubiheen, Jerrold S. Petrofsky, Noha S. Daher, Everett Lohman, Edward Balbas

College of Health & Human Services (TUN) Publications and Research

BACKGROUND: One of the effects of diabetes mellitus (DM), peripheral neuropathy, affects the sensation in the feet and can increase the chance of falling. The purpose of the study was to investigate the effect of 8 weeks of Tai Chi (TC) training combined with mental imagery (MI) on improving balance in people with diabetes and an age matched control group.
MATERIAL AND METHODS: Seventeen healthy subjects and 12 diabetic sedentary subjects ranging from 40–80 years of age were recruited. All subjects in both groups attended a Yang style of TC class using MI strategies, 2 sessions a week …
