21. Effects of exercise and amino acid intake on mechanisms regulating protein synthesis and breakdown in human muscle
Sammanfattning : Skeletal muscle adapts differently to specific modes of exercise, where resistance training results in muscle growth and endurance training induces mitochondrial biogenesis. These are results of molecular events that occur after each exercise session, increasing the expression of specific genes and the rate of both synthesis and breakdown of protein. LÄS MER
22. Endogenous antioxidants in human skeletal muscle and adaption in energy metabolism : with reference to exercise-training, exercise-related factors and nutrition
Sammanfattning : The antioxidant homeostasis is determined by a wide array of interacting cellular antioxidants, as well as being influenced by the homeostasis in energy metabolism. Changes in antioxidant homeostasis, as a consequences of altered production of reactive oxygen species (ROS). and/or by changes in the resident levels of antioxidants. LÄS MER
23. Metabolic and Cardiovascular Responses During Variable Intensity Exercise
Sammanfattning : Previous research investigating endurance sports from a physiological perspectivehas mainly used constant or graded exercise protocols, although the nature ofsports like cross-country skiing and road cycling leads to continuous variations inworkload. Current knowledge is thus limited as regards physiological responses tovariations in exercise intensity. LÄS MER
24. Physiological response to exercise in the Icelandic horse
Sammanfattning : This thesis examined the exercise physiology of the Icelandic horse by: 1) studying physiological response in stallions and mares of different ages performing a true breed evaluation field test (BEFT); 2) comparing the effect of ridden tölt and trot at three speeds on physiological response; 3) evaluating physiological response to a simulated 100 m flying pace race; 4) measuring the effect of increasing body weight ratio (BWR) of rider to horse (20, 25, 30, and 35 %) on physiological response in an standardised incremental field exercise test at tölt at 5.4 m/s; and 5) determining the effect of rider on physiological response.

25. Regulation of protein synthesis in human skeletal muscle : separate and combined effects of exercise and amino acids
Sammanfattning : Skeletal muscle is a highly plastic tissue which has the ability to adapt to various forms of external stimuli such as diverse modes of contractile activity. Thus, performance of endurance exercise over several of weeks results in increased oxidative capacity. LÄS MER
