Abstract

This study was carried out to investigate the expression of Irisin(browning) by natural factors such as 'cold' and 'aging' and was undertaken to understand the health factors and positive effects associated with fat metabolism, which can be attributed to natural factors. First study was that 6 healthy subjects participated in and exposed cold for 4 weeks(300 min/day, 5 times/week, -15°C~-25°C). Body composition, isokinetic muscular function(60°/s and 240°/s by Humac Norm) and irisin concentration were measured pre and post cold exposure. Second study was that we examined the changes of serum Irisin expression by aging process(10wk, 80wk) and aerobic exercise. Conduct of aerobic exercise with regular cold exposure or aging process is a factor that increases browning of white fat The increase of Irisin is a positive factor for the imbalance of fat metabolism and improvement of performance.
