Schematic overview of the experimental protocol.
Set-up for the five tests. D = duration, v = velocity, HR = heart rate, RPE = rate of perceived exertion, * = resistance is individually determined.
Fig 3.
Extracted variables for the a) isometric strength test, b) sprint test, c) Wingate test and d) graded exercise test. Strength (F) is the average of both arms (in blue); power output (PO) is the sum of both arms (in green); velocity (v) is the average of both arms (in red).
Fig 4.
Comparison of the individual estimated P30 (left graph) and POpeak (right graph) with the actual measured P30 and POpeak. The number attached to the symbol is the same as participant numbers in Table 1. Dotted lines correspond w a perfect fit and solid lines represent 20% boundaries. A = measured in Amsterdam, G = measured in Groningen, F = female, M = male.
