What are Threshold-Intervals in Cycling?

Threshold-intervals in cycling are intense workouts designed to improve an athlete’s ability to sustain a high level of effort over time. These intervals involve cycling at or near an athlete’s lactate threshold heart rate (LTHR), which is the maximum effort a person can sustain for an extended period of time before their performance begins to suffer. The goal of threshold-intervals is to increase the athlete’s lactate threshold, allowing them to sustain a higher level of effort for longer periods of time.

The typical protocol for threshold-intervals involves cycling at LTHR for 15-30 minutes, followed by a short rest period and then another interval at LTHR. This process is repeated for several rounds, with the total interval time increasing as the athlete’s fitness level increases. Studies have shown that when done correctly, threshold-interval workouts can improve an athlete’s performance by up to 10-15%.

Threshold-intervals are an important part of any cyclist’s training program. They help to improve an athlete’s endurance and allow them to perform at a higher level for longer periods of time. With the right approach, threshold-intervals can be a great way to take your cycling performance to the next level.


The Origin of the Term “Threshold-Intervals” in Cycling

The term “threshold-intervals” first appeared in the context of cycling in the late 1990s, when it was used to describe a type of interval training designed to improve a cyclist’s aerobic capacity. The term was coined by cycling coach Joe Friel, who was based in the United States at the time.

Friel’s approach to threshold-intervals involved alternating hard and easy efforts. The hard efforts were designed to push the rider’s aerobic threshold, while the easy efforts allowed the rider to recover. This type of interval training was designed to improve a cyclist’s ability to sustain a high level of performance for long periods of time.

Threshold-intervals have become a popular training tool for cyclists in recent years, as they are seen as an effective way to improve aerobic capacity and performance. Many professional cyclists use threshold-intervals as part of their training regimen, and the technique has become a staple of cycling training programs around the world.
