The best heart rate monitor training uses monitors to assess how exertion influences your pulse between maximum and minimum (resting) heart rates. This is how exercisers determine target heart rate (THR) zones: those measurements that indicate positive and healthy heart exertion.
Heart Rate Monitor Training: Recovery Zone
Those who train for basic endurance and aerobic capacity should engage heart rate monitor training not exceeding 70 percent of their maximum heart rate. This type of heart rate monitor training burns fat while allowing muscles to re-energize with glycogen. All easy-recovery falls into this category.
Heart Rate Monitor Training: Aerobic Zone
The aerobic zone develops the cardiovascular system: the body’s ability to import oxygen to working muscles while exporting carbon dioxide from them. Typically, exercisers aim for a target heart rate between 70 and 80 percent of maximum in this type of heart rate monitor training.
Heart Rate Monitor Training: Anaerobic Zone
The training zone uses the lactic acid system to draw on glycogen in the muscles themselves as the primary form of fuel. Those using this heart rate monitor training zone eventually make the lactic acid by-product last longer. The anaerobic zone requires between 80 to 90 percent of maximum heart rate to be effective.
Heart Rate Monitor Training: Red Line Zone
Put simply, your heart can’t work any harder: 90 to 100 percent maximum. Only very fit people are able to train in this heart rate monitor training zone, as it relies on fast-twitch muscles fibers for short, intense burst of speed.
When exercisers notice a lower heart during a given intensity, the body is becoming more fit. However, it is important to remember that some external factors also influence fluctuating heart rates: dehydration, heat, humidity and altitude to name a few.
