Perceived Barriers, Benefits And Motives For Physical Activity: Two Primary-Care Physical Activity Prescription Programs, Asmita Patel, Grant M. Schofield, Gregory S. Kolt, Justin Keogh

Justin Keogh

This study examined whether perceived barriers, benefits, and motives for physical activity differed based on allocation to 2 different types of primary-care activity prescription programs (pedometer-based vs. time-based Green Prescription). Eighty participants from the Healthy Steps study completed a questionnaire that assessed their perceived barriers, benefits, and motives for physical activity. Factor analysis was carried out to identify common themes of barriers, benefits, and motives for physical activity. Factor scores were then used to explore betweengroups differences for perceived barriers, benefits, and motives based on group allocation and demographic variables. No significant differences were found in factor scores based on …

Fatigability And Recovery Of Arm Muscles With Advanced Age For Dynamic And Isometric Contractions, Tejin Yoon, Bonnie Schlinder-Delap, Sandra K. Hunter

Exercise Science Faculty Research and Publications

This study determined whether age-related mechanisms can increase fatigue of arm muscles during maximal velocity dynamic contractions, as it occurs in the lower limb. We compared elbow flexor fatigue of young (n = 10, 20.8 ± 2.7 years) and old men (n = 16, 73.8 ± 6.1 years) during and in recovery from a dynamic and an isometric postural fatiguing task. Each task was maintained until failure while supporting a load equivalent to 20% of maximal voluntary isometric contraction (MVIC) torque. Transcranial magnetic stimulation (TMS) was used to assess supraspinal fatigue (superimposed twitch, SIT) and muscle relaxation. Time …

An Intergenerational Leisure Activity Program To Promote Successful Aging, Rachel Becker, Jason Zacharias

Occupational Therapy Capstones

PROBLEM: By the year 2030, older adults who are 65 years of age or older will account for 20% of the US population (Center for Disease Control, 2008); however, the rate of successful aging has decreased 25% from 1998 to 2004 (McLaughlin, Connell, Heeringa, Li, &Roberts, 2009).

PURPOSE: The purpose of this scholarly project is to develop an intergenerational program that will promote successful aging of older adults. METHOD: A literature review was conducted on older adults and successful aging using PubMed, OT search, CINAHL, AJOT, Google scholar, and textbooks. RESULTS: Researchers indicated that intergenerational programs promote successful aging and …

Sex Differences In Marathon Running With Advanced Age: Physiology Or Participation?, Sandra K. Hunter, Alyssa A. Stevens

Exercise Science Faculty Research and Publications

The sex difference in marathon performance increases with age and place of the finisher, even at the elite level. Sociological factors may explain the increased sex gap, but there is limited empirical evidence for specific factors.

Purpose: The purposes of this study were to determine the sex difference in velocity for the marathon across the place of finisher (1st–10th place) with advanced age and (2) to determine the association between the sex difference in participation (ratio of men-to-women finishers) and the sex difference in running velocity.

Methods: Running times of the first 10 placed men and women in the 5-yr …
