Dr. Nils Hakansson of Biomedical Engineering (BME) in collaboration with Human Performance Studies (HPS) and Medical Laboratories (ML) is requesting volunteers 55 years of age or older for a study to determine whether Blood Flow Restriction therapy during moderate exercise results in the improved functional activity and health outcomes. The results of the study may provide a new approach to promoting health through moderate exercise. During the study, participants will pedal an exercise bike with or without Blood Flow Restriction therapy for approximately 30 minutes, two times per week over a four-week period. During the four weeks participants will perform the following procedures: Blood and saliva samples will be collected and tested for proteins related to the exercise at the beginning and end of three pedaling sessions. Lactic acid will be measured from a drop of blood obtained from participants’ finger tips every five minutes (six times total per visit). A 30-second sit-to-stand activity will be performed at the end of each visit to assess exercise functional outcomes. Heart rate will be measured as participants pedal an exercise bike. Participants must meet the following criteria: Participants must be age 55 or older No known muscular disorders No known neurological disorders No known cardiopulmonary disorders No use of nicotine products Not have diabetes Not be in an active exercise program All studies will be performed at the Human Performance Laboratory (Room 210) located in the Heskett Center. To participate in the study, follow the link below.
