Physical EducationExercise physiologyA2/A-levelOCR Created by: RJ_Created on: 06-12-16 09:23 Aerobic Capacity The ability to take in, transport and use oxygen to sustain prolonged periods of aerobic/sub-maximal work. 1 of 18 VO2 max The maximum amount of oxygen that can be taken in and used by the body in one min. 2 of 18 Mitochondria Organelle in a cell which is the site for aerobic respiration. 3 of 18 Myoglobin Red pigment in muscle cells that acts as a temporary store for O2 and transports it to the mitochondria. 4 of 18 Slow Oxidative Muscle Fibres Muscle fibers designed for low intensity long duration activities. 5 of 18 Hypertrophy Increase in size of tissue, e.g. Heart and skeletal muscle. 6 of 18 Bradycardia A decreased resting heart rate (60bpm or below). Generally associated with endurance athletes. 7 of 18 Maximum cardiac output (Qmax) The maximum volume of blood that can be pumped out of the left ventricle in one min. 8 of 18 OBLA Onset of blood lactate accumulation - the point at which lactic acid levels begin to increase significantly. 9 of 18 Continuous Training Exercise performed at a steady pace to completion without any periods of rest. 10 of 18 Interval Training A system of training that alternates periods of exercise with periods of rest. 11 of 18 Fartlek Training A form of continuous training in which there are periods of varied intensity which stress both the aerobic and anaerobic energy systems. 12 of 18 Target Zone The heart rate which indicates the level of intensity of exercise which produces maximum training benefits. 13 of 18 Maximum Heart Rate (HRmax) The maximum number of times the heart beats in one min (220-age) 14 of 18 Energy Continuum Ther relative contribution of each energy system depending on the intensity and duration of the exercise. 15 of 18 External Gas Exchange Gas exchange that occurs between the lungs and the blood. 16 of 18 Internal Gas Exchange Gas exchange that occurs between the blood and the tissue cells, e.g. muscle 17 of 18 Overload Principle of training whereby the body is made to work harder than normal. 18 of 18
