Study Arms (2)

Widely pristine area

EXPERIMENTAL

Outdoor mountain hiking (approximately 6 hours, 8km, 800 altitude meters, estimated speed: 4km/h \[uphill\], 5.2km/h \[downhill\]) in a widely pristine area with moderate intensity (Rating of perceived exertion: \~ 11-15).

Behavioral: Mountain hiking

Anthropogenically influenced area

ACTIVE COMPARATOR

Outdoor mountain hiking (approximately 6 hours, 8km, 800 altitude meters, estimated speed: 4km/h \[uphill\], 5.2km/h \[downhill\]) in an anthropogenically influenced area with moderate intensity (Rating of perceived exertion: \~ 11-15). All characteristics of the hiking (duration, time, difference in altitude, ...) are planned to be comparable to the experimental condition except the area.

Behavioral: Mountain hiking
