CARDIORESPIRATORY ENDURANCE AEROBIC EXERCISE (part 2) EXERCISE FOR CARDIORESPIRATORY ENDURANCE •Using large muscle groups (legs) •Must be continues for minimum of 20 min (non-stop) •Must be rhythmical •Aerobic – Low to Moderate Intensity (60-85% of MHR) AEROBIC EXERCISE means "with oxygen", and refers to the use of oxygen in muscles' energy-generating process. INTENSITY – sub maximal and lower 55 – 85% of individual maximum HR Heart rate is an excellent indicator of intensity during aerobic exercise ENERGY DURING AEROBIC EXERCISE 1. CARBOHYDRATES (GLUCOSE) O2 + C6H12O6 ENERGY + CO2 + H2O 2. FAT is used ONLY WITH GLUCOSE AND FAT RELEASING ENZIMES STORA GE PLACE TIME ENERG Y SUPPLY CARBOHYDRATE FAT S FAT CELLS MUSCLES (glycogen), BLOOD, LIVER UP TO 1 HOUR CAN BE INCREASE UP TO 2.5x UNLIMITED UP TO 80% http://on.aol.com/video/kathrine-switzer-first-woman-to-enter-the-boston-marathon517280189 • http://www.youtube.com/watch?v=LoG0G rs4EEo • Todd Akin ANAEROBIC EXERCISE oxygen supply in skeletal muscle is LOWER than demand INTENSITY – sub maximal and maximal 85-100% of individual maximum HR LENGTH – up to 3 min depending on intensity (100% intensity – 45 sec) ENERGY DURING ANAEROBIC EXERCISE 1. CARBOHYDRATES (GLUCOSE) ONLY lactic acid is produced due to insufficient oxygen supply Anaerobic workout (running) Anaerobic threshold
