Does cold-water endurance swimming affect pulmonary function in healthy adults?
Illidi, Camilla Rønn; Stang, Julie; Melau, Jørgen; Hisdal, Jonny; Stensrud, Trine (Peer reviewed; Journal article, 2021)Abstract: The acute effects of cold-water endurance swimming on the respiratory system have received little attention. We investigated pulmonary responses to cold-water endurance swimming in healthy recreational triathletes. ... -
Exhaled nitric oxide after high-intensity exercise at 2800 m altitude
Stang, Julie; Bråten, Veslemøy; Caspersen, Cecilie; Thorsen, Einar; Stensrud, Trine (Journal article; Peer reviewed, 2014-01-22)Background: Nitric oxide (NO) concentration in exhaled gas is a marker of some inflammatory processes in the lung, and endogenous NO plays a role in the physiological responses to exercise and altitude. The aim of this ... -
Exhaled nitric oxide concentration in the period of 60 min after submaximal exercise in the cold
Stensrud, Trine; Stang, Julie; Thorsen, Einar; Bråten, Veslemøy (Journal article; Peer reviewed, 2014-10-10)Background: Fractional expired nitric oxide (FENO) is decreased after exercise. The effect of exercise in the cold upon FENO is unknown. Purpose: To examine changes in FENO after a short, high intensive ... -
Expired nitric oxide after high intensive exercise at altitude
Stang, Julie (Master thesis, 2010)Nitric oxide has, as an exhaled biomarker, become an accepted tool in the management of inflammatory airway diseases, with its non-invasive, quick and easy measurement procedures. However, its use is still discussed and ... -
