The Differences of Aerobic and Anaerobic Exercises on Metabolism

“Metabolism is the most basic job your body must complete in order to survive and function. How your metabolism works depends on the type of exercise you’re doing at the time. There are two types of exercise, aerobic and anaerobic. Aerobic exercise, such as jogging, depends on oxygen to produce energy, while anaerobic exercise can be performed in the absence of oxygen. During aerobic exercise, your body has a steady supply of oxygen to produce ATP, giving your body a tremendous energy-yielding capacity. Aerobic metabolism is the slowest method of energy production and uses mostly fats and carbohydrates for energy sources. Anaerobic metabolism is the dominant source of energy for short, high-intensity activities such as weightlifting and sprinting. Anaerobic metabolism provides energy at a high rate but in small amounts, which is why your muscles fatigue after only a dozen reps. [1]

The fitness industry is experiencing a surge of interest and growth in high intensity interval training (HIIT). This method of training involves repeated bouts of high intensity efforts that range from 5 seconds to 8 minutes followed by recovery periods of varying lengths of time. Because of the nature of high intensity exercise, the effectiveness of this type of training for fat burning has been examined closely. A metabolic benefit of HIIT training is the increase in post-exercise energy expenditure referred to as Excess Post-exercise Oxygen Consumption (E.P.O.C.). Following an exercise session, oxygen consumption (and thus caloric expenditure) remains elevated as the working muscle cells restore physiological and metabolic factors in the cell to pre-exercise levels. This translates into higher and longer post-exercise caloric expenditure. [2]”

Want to get some great HIIT workouts into your routine? Here at Synergy we offer multiple HIIT training groups! We have a HIIT Spin group on Thursdays at 12:15pm and one bright and early Friday morning at 6am. While both groups meet for under an hour, these high-intensity workouts will have you sweating! We also offer two HIIT & Core groups; one Wednesday mornings at 6am and one Thursday evenings at 5:30pm.
