In aerobic training, what intensity range is defined as 50 to 85% of your heart rate reserve with activity lasting from 30 minutes to several hours?

The intensity range of 50 to 85% of your heart rate reserve is indicative of long, sustained efforts that are characteristic of aerobic training. This training style is aimed at improving cardiovascular endurance and efficiency. Specifically, the long slow distance approach emphasizes maintaining a moderate pace over extended periods, often lasting from 30 minutes to several hours.

This method is particularly effective for building a solid aerobic base, enhancing the body's ability to utilize oxygen, and improving overall endurance. It allows the body to adapt to sustained efforts by increasing the capillary density around muscles and improving the efficiency of energy production.

While the other training modalities have their respective benefits, they do not align with the defined intensity range or duration in the same way that long slow distance training does. For instance, high-intensity interval training focuses on short bursts of intense activity, while Fartlek training involves varying speeds and intensities rather than maintaining a steady, moderate effort. Moderate intensity training can refer to various practices, but it doesn’t specifically capture the extended duration as well as long slow distance does.
