Public Posting As A Strategy To Increase Walking: A Worksite Intervention, Rayleen Earney, Timothy J. Bungum

Environmental & Occupational Health Faculty Publications

Because most American adults do not meet recommended physical activity guidelines, the need for new and innovative strategies is apparent. The current study employed public posting in an attempt to increase walking behavior in a worksite setting. Pedometer generated data was publicly posted in a prominent location in the worksite. In our study that utilized a pre-experimental design, we found that walking steps were statistically higher during the intervention and in a post intervention period as compared to the baseline data. We conclude that the public posting of physical activity data has the potential to increase walking behavior.

The Effects Of Movement Based Interventions On Doms And Muscle Damage Following Eccentric Exercise, Zainal A. Zainuddin

Theses: Doctorates and Masters

Delayed onset muscle soreness (DOMS) is a common symptom experienced by most adults following unaccustomed exercise. It is known that DOMS is peculiar to eccentric exercise that results in muscle damage which is characterized by prolonged loss of muscle function. DOMS and subsequent impaired muscle function, reduces the ability to maximize performance of daily living tasks, and has negative effects on sports adherence and activity based healthy lifestyle. Thus, treatments to ameliorate DOMS and enhance recovery of muscle function are important.
