Fig. 3

Annotated examples of pre- and post-training documentation including (a) the skill training focus according to a skill training periodisation plan (i.e., top part; see [22]); (b) the measurement of perceived physical well-being (i.e., the middle-left graph for goalkeeper 1 and middle-right graph for goalkeeper 2) and (c) the exemplary physical output data on each goalkeeper’s training loading (i.e., the bottom-left graph for goalkeeper 1 and bottom-right graph for goalkeeper 2). Notably, the data shown in the graphs is only representative of that usually collected by sport scientists and coaches in high-performance training environments
