Intermediate-day Onions produce bulbs where the total amount of daylight is approximately 12-14 hours, which is the amount mid-section states receive in the summer. Intermediates are also known as day-neutral onions. Long-day Onions produce bulbs where the total amount of daylight is 14-16 hours.
Anaerobic Zone. The anaerobic zone is slightly more intense than the aerobic zone. Anaerobic means without oxygen, so don't be surprised if you are unable to speak except for short words at a time in this zone. The anaerobic zone is 80 to 90 percent of your maximum heart rate.erobic Zone. The aerobic target zone is 70 to 80 percent of your maximal heart rate. Multiply your maximum heart rate by this percentage to determine the intensity you must maintain to remain in this zone.
The anaerobic energy system provides energy in the absense of Oxygen. This is used in the first few minutes of all exercise, before there is suffiecient oxygen available at the muscles for aerobic metabolism.ue to lactic acid production, this energy system can only be predominant for up to 2 minutes. Following anaerobic exercise, despite the metabolic process used not requiring oxygen, your body will be in Oxygen Debt and so your respiration rate will be very high.
