Interplay of 3 Energy Systems
Surfing energy system interplay-
At the start of surfing when you are carrying the board out to the water your body would be working in the aerobic system because you are only working in a sub maximal intensity of <80% max HR for over 75 seconds. When running out to the water with our board your body would move into the anaerobic glycolysis system because you are working at a 85%-90% max HR for a longer period of time for about 5-15 seconds before moving into the ATP/PC system to jump on to the board and start to paddle out into the water/wave which is high intensity 95%+ max HR for a short period of 5 seconds with peak power of 2-4 seconds than you will move into the anaerobic system for a longer intensity. When you reach the spot in the water and you are waiting for a wave your body will be working in a aerobic system because you don't require a high intensity of energy and aerobic system is a long duration when it is the dominate system. When you are paddling with the wave you are working to keep up with the wave which is a high intensity for a short duration. as you are riding the wave you are working in the anaerobic system because you are just riding with the board. Its an increased intensity from aerobic system but isn't high enough to be the ATP/PC system. After you finish the wave you would be working in the aerobic system because you don't require a high energy level to hold your board.
