Diagram of timeline for testing protocol. The top row shows the order of upper body power (UBP) tests and rest intervals (RI), as well as the total time accumulated (in parentheses) within each measurement period. The second row shows the approximate times at which eight separate fingertip blood lactate samples were collected (indicated sequentially as L1-L8). Arrows within this same row point toward the time period at which the test actually occurred (shown as darkened boxes within third row). Times within parentheses in the third row indicate actual RI time following each test.
