Copeland Creek Riparian Restoration Exercise Project

Project Description: Physical activity is a significant part of watershed restoration. Volunteer work crews clean up refuse, maintain paths, plant natives, and remove invasive species. These activities can potentially benefit the health of the participants. This project examines the effects of self-paced restoration activities on heart rate and metabolism. We explore the importance of the type and duration of activity. Often gym sessions or other traditional forms of activity last 45 minutes to 1.5 hours, but every day activities like gardening can be an all day event.

Duration: Spring 2013 - ongoing

Type of Educational Activities: Service-learning

Project Faculty: Bulent Sokmen (Kinesiology)

Partners: Sonoma County Water Agency, City of Rohnert Park (Susan Haydon), Center for Environmental Inquiry (Suzanne DeCoursey)

Participating Courses: Physiology of Exercise (KIN 360) - 6 students

Location: This class project is conducted at Sonoma State University’s garden, Copeland Creek, and SSU's Fairfield Osborn Preserve.

Activities: Class participants performed various self-paced gardening-related activities, varying in physical activity intensities. During 2013 studies, resting heart rates (HR) were recorded prior to the activity to get baseline values and then every 10 min for 60 min. During 2014 studies, blood glucose, blood pressure and heart rate were recorded every 30 minutes for 2 hours and compared to resting and walking activities.

Participants: Students in KIN 101 and Center for Environmental Inquiry's Land Management Training (11 women & 10 men) (20.1±1.78 years; 69.7±9.3 kg; 171.8±5.2 cm) volunteered for this class project.

Measurements are conducted by SSU students under the guidance of Dr. Bulent Sokmen.

Results Summary: When compared to walkers, people engaged in self-paced gardening/restoration activities (e.g., shoveling, raking, carrying dirt in a wheelbarrow, and placing leaves into a container) showed similar reductions in blood pressure, but burned more calories and sustained higher heart rates.
