Yhteens\u00e4 28 harjoittele-matonta, normaalipainoista tervett\u00e4 miest\u00e4 (ik\u00e4 40-55 v.) satunnaistettiin HIT (n = 14) ja MIT (n =14) ryhmiin.

Oikean kammion metaboliaa tutkittiin positroniemissiotomografialla (PET) ja rakenteellisia ja toiminnallisia parametreja magneettikuvauksella (MRI).

HIT has been shown to rapidly improve the pumping capacity of the heart and aerobic fitness similarly compared to more time-demanding traditional moderate-intensity training (MIT) such as jogging. As the most common reason people cite for their inactivity is the lack of time, HIT could be an effective alternative to improve both individual and public health. The purpose of this study was to investigate the effects of HIT and MIT on the right ventricular glucose and fat metabolism along with its structural and functional parameters. In total, 28 untrained, lean and healthy men of age 40-55 years were randomized into HIT (n = 14) and MIT (n = 14) groups. Both groups had six training sessions within two weeks. In a session, the HIT group did 4-6 x 30 s all-out cycling with 4 min recovery between bouts, whereas the MIT group cycled for 40-60 min at 60% VO2max. Right ventricular metabolism was measured with positron emission tomography (PET) and structural and functional parameters with magnetic resonance imaging (MRI). The main finding was that the right ventricular glucose uptake was decreased (p = 0.001 for the training effect) after both HIT (-22 %) and MIT (-15 %) whereas fat metabolism remained unchanged (p = 0.96). Further, end-diastolic and end-systolic volumes were increased (HIT 5% and 6%, MIT 3% and 7%, p = 0.002 and 0.007) whereas ejection fraction was decreased (HIT -2%, MIT -4%, p = 0.034). However, none of the changes were different between the training groups (p > 0.05 for the group*training effect). Hence, two weeks of training induced adaptations in right ventricular glucose metabolism and volume while its mass and stroke volume remained unchanged.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Marja Heiskanen (mheiskan) on 2015-05-18 06:44:38.518282.
