Adhering to precise execution standards in the conduct of all PRT activities ensures the development of body management and fundamental movement skills. PROGRESSION. Progression is the systematic increase in the intensity, duration, volume, and difficulty of PRT activities. The proper progression of PRT activities allows the body to positively adapt to the stresses of training. When progression is violated by too rapid an increase in intensity, duration, volume or difficulty the Soldier is unable to adapt to the demands of training.
The intensity at which you lose and regain the tone is your absolute threshold for that particular tone. Weber defined the absolute threshold as the intensity at which the stimulus was detected on 50% of trials.A stimulus detected on, say, 20% of trials is by this definition below the absolute threshold for detection, although of course it is sometimes detected nevertheless.he difference threshold is the average of the two differences between the comparison stimuli and the standard. Weber noticed that the difference threshold is a constant proportion of the initial stimulus intensity.
