Maximal oxygen uptake (VO₂max) declines with advancing age and is a predictor of morbidity and mortality risk. The purpose here was to assess the utility of constant load tests performed either above or below peak work rate obtained from a graded exercise test for verification of VO₂max in older adults. Twenty-two healthy older adults (9M, 13F, 67 ± 6 years, BMI: 26.3 ± 5.1 kg·m⁻²) participated in the study. Participants were asked to complete two experimental trials in a randomized, counterbalanced cross-over design. Both trials (cycle ergometer) consisted of (1) an identical graded exercise …

Postprandial Exhaled Nitric Oxide Responses In Older And Younger Adults With And Without Acute Exercise, Molly Miller

Masters Theses, 2020-current

A single high fat meal (HFM) increases airway inflammation in young, healthy individuals. Additionally, aging increases airway resistance and inflammation, though the airway inflammatory response to a HFM has not been investigated. Exercise is a natural anti-inflammatory, but has yet to be administered with a HFM as a method to study postprandial airway inflammation in older adults. Purpose: To investigate whether older individuals have greater postprandial airway inflammation compared to younger counterparts, and to explore whether exercise may modify the postprandial airway response in older adults. Methods: 12 younger adults (23.3±3.9 years; 5 M/7 F) and 12 older adults (67.7±6 …

Self-Selected Maximum But Not Jogging Speed Decreases With Age In Male And Female Runners, Heather Hamilton, Rumit Singh Kakar

College of Health Sciences Posters

Introduction: Running velocity decreases with age, likely resulting from physiological and musculoskeletal changes associated with aging. Females experience a more rapid decline in physical performance during middle age than males, therefore it is important to consider separate-sex analyses when studying running biomechanics and running-related injury. The purpose of this study was to determine the relationship between age and different running speeds separately for female and male runners.

Methods: Male (n=33) and female (n=46) runners (ages 18–65 years) ran at their self-selected JOG (long distance) and MAX (maximal running) pace on a treadmill. Running velocity was recorded. Simple linear regression was …
