Men and women older than 50 are invited to participate in two studies being conducted by the exercise physiology research laboratory of biology assistant professor Tinna Traustadottir.

In one study, participants who are older than 50 and not currently exercising regularly and who have not been diagnosed with chronic diseases will exercise three days per week as part of an eight-week exercise intervention study. Study personnel will supervise the training, which takes place at the Health and Learning Center. Membership is not required to participate. There also will be two five-hour oxidative stress challenges that involve having a blood pressure cuff inflated for three 10-minute periods during the first half hour of the visit, followed by periodic blood draws for the remaining four hours. Financial compensation is being offered to participants who complete this study.

A second study is investigating the effects of acute exercise on the resistance to oxidative stress in participants ages 50 and older. Individuals must be generally healthy and can be physically active but not highly fit. The study requires six visits to the lab: a screening visit; a physician-supervised exercise stress test; two visits where the participant will complete the test of resistance to oxidative stress, one of those will be preceded by acute exercise performed on the day prior, and the other will be preceded by a blood draw on the day prior.
