The decision strategy used to adapt the training load. Legend. After each training session, the participants rated their training session according to the perceived discomfort (0–10) and perceived exertion (0–10). RPD was divided into low (0–3), moderate (4–6) and high (7–10). RPE was also divided into three categories: very light to moderate (0–6), vigorous (7), and hard to maximum effort (8–10). Arrows in the last line illustrate the training load adaptation for each of the nine possible parameter combinations. This decision strategy originated from and the figure is adapted from [18]
