Sports ScienceBioenergeticsUniversityNone Created by: anniecritchlowCreated on: 07-05-19 09:59 What stimulates structural and functional adaptions to improve performance in specific physical tasks? Training 1 of 27 What is overload? Systems or tissues exposed to stimuli beyond what it is accustomed to in order to get training effect 2 of 27 What is specificity? Training effects are specific to muscles involved, fibres recruited and principle energy systems involved 3 of 27 What is reversibility? Gains can be as quickly lost as they are gained when the stimulus is removed 4 of 27 2-3 months of endurance training usually increases VO2 max by? 15-20% 5 of 27 Endurance training should be done at... >50% VO2 max 6 of 27 A large contribution of improving skeletal muscle bioenergetics is due to... Improved muscle O2 extraction 7 of 27 What is not a metabolic adaption to endurance training? Less substrate oxidation 8 of 27 What happens to mitochondria content with endurance training? Increases 9 of 27 How does mitochondrial volume correlate with VO2 max? Positive 10 of 27 A greater mitochondrial oxidative capacity after training does not result in... Larger use of ATP and PCr at onset 11 of 27 Endurance training has what effect on GP and PFK activity Lowers GP activity and PFK activity 12 of 27 After endurance training, is there more glycolysis or oxidative phosphorylation taking place? Oxidative phosphorylation 13 of 27 Endurance training has what impact on fuel utilisation? More fat oxidation, more CHO oxidation 14 of 27 What is not an effect of using more fat oxidation after endurance training? Quicker rate of reaction 15 of 27 After endurance training, there is higher mobilisation and transport of FFA into muscle? True 16 of 27 There are decreased intramuscular triacyglycerol stores after endurance training? False 17 of 27 There is decreased capacity for beta-oxidation, TCA cycle and OXPHOS after endurance training? False 18 of 27 What is not a reason for the increased capacity for CHO metabolism? Increased liver stores of glycogen 19 of 27 What is not a way that endurance training improves acid base balance? Decreased reliance on fat reduced pyruvate formation 20 of 27 How does interval training improve anaerobic capacity of muscle? Increased buffering capacity of H+ 21 of 27 How does interval training affect activity of GP, PFK and LDH? Increases activity of all 22 of 27 Endurance training can induce fibre type shifts from fast to slow muscle? True 23 of 27 What is not a feature of type I muscle fibre? Higher ATPase activity 24 of 27 What increases muscle fibre cross-sectional area to increase force production? Resistance training 25 of 27 What is not a result of strength training? Increases mitochondrial capacity 26 of 27 What is described as the maximal force that a muscle can generate Muscular strength 27 of 27
