WebIn cycling training, the term threshold refers to your functional threshold power (FTP). Your FTP is an estimate of the highest amount of power you can sustain for sixty minutes. This metric helps scale your workouts to your current fitness by defining your power zones for power-based training. Fortunately, you won’t have to complete an all ... WebIn other words, the CT value is the lowest PCR cycle number at which the fluorescent probe signal for the amplified target sequence is greater than the minimal detection level determined during validation by the user1,2. Lower CT values are associated with a higher amount of target viral sequence (copy number) in the sample tested.

When the Ct value is low, it means that there was a lot of starting material (many pages with the sentence we were interested in, or many copies of the coronavirus).

WebThe crux of power-based training is a benchmark called FTP, which stands for Functional Threshold Power. This is an estimated measure of your highest sustainable power, measured in watts, that can be held for one hour. FTP is an important metric because it’s used to scale every workout to your specific needs. Web1 nov. 2024 · The cycle threshold (Ct) is the number of amplification cycles required for the fluorescent signal to become strong enough to confirm a positive result. Because of the way PCR works, the more virus in a sample to start with, the fewer cycles are needed for a signal to be detected – the lower the Ct value.
