The Trainer is 'IN' - Anaerobic vs. Aerobic Exercise
With the popularity of HIIT-style classes on the rise, it’s important to know that these classes do more than just allow you to burn more calories in a shorter period of time. HIIT-style classes train both our anaerobic (without oxygen) and aerobic (with oxygen) metabolic systems, allowing us to rapidly improve our exercise capacities, tolerance, and performance. Our aerobic system is the system that works the majority of the time, while our anaerobic system only works during high-intensity and short duration exercise (less than 3 minutes). The point where the need for energy exceeds what the aerobic system can produce is known as the anaerobic threshold. This metabolic threshold represents the intensity of exercise where anaerobic metabolism produces waste by products that lead to a deterioration in performance known as fatigue (impairing muscle contractions). As we approach this threshold we start to breathe harder and exercise simply becomes more uncomfortable. Benefits of anaerobic training include increased endurance, greater ability to stand fatigue, improved cardiovascular fitness, and the building of overall strength and muscle mass because strength training is the most common form of anaerobic training. So next time you have to do a set of burpees remember the benefits of being out of breath and uncomfortable!
